A 1904 method, made for right now

Decide what you're saving for. Then go live your life.

Kakeibo is a 120-year-old Japanese money method that still holds up because it's genuinely simple: set your savings number first, track everything in four easy categories, then look back and see what actually happened. This is that method, built as something you'll actually want to open — no spreadsheets, no guilt trips, no 47-tab budget doc.

Takes about two minutes to set up. Future-you is already glad you did.

How it works

Three steps, the same order every month

Not three features to explore in any order — a sequence. Kakeibo works because the plan comes before the spending, not after it. Once it clicks, it just clicks.

1
Plan
Set a savings goal and write down what you're planning to cut back on this month — before you spend a single rupee. That's the whole trick.
2
Track
Log each purchase into one of four categories. Takes about ten seconds, and the weekly buckets show exactly what's left to spend.
3
Reflect
Close the week, close the month, then look back at the whole year. Patterns show up that a single month never reveals — and it feels genuinely good to see.

Not just a philosophy — a working tracker

Where your money details actually go

Your account numbers never leave this device

UPI IDs and account names are saved only in this browser's local storage — never uploaded, never synced, never sent in a single network request this app makes. On this device, they're also encrypted at rest and masked until you unlock Settings with your device's own authentication (Windows Hello, Touch ID, Face ID, or Android biometric/screen-lock), falling back to a PIN only when a browser or device can't do that — so a glance at your screen, or someone else picking up this device, doesn't show them in the clear. Everything that says what you bought or how much you saved is designed to be encrypted before it ever reaches a server, so that not even we could read it. That's the one rule this app doesn't compromise on for convenience.

What Is Kakeibo? A Beginner's Guide to Japanese Household Budgeting

Kakeibo (say it: kah-KAY-boh) is a simple Japanese method for tracking household money. You write down what you earn and what you spend, sorted into four easy categories — and you decide how much to save before you spend, not after.

Where kakeibo comes from

Kakeibo was created in 1904 by Hani Motoko, Japan's first female journalist. She wanted an easy way for ordinary households to control their money without needing to be good at maths. It caught on, and it's still taught in Japanese schools today — even young children use a simplified version. The word itself just means "household financial ledger."

The core idea: save first, spend what's left

Most budgets fail for the same reason: people spend all month, then look at whatever's left over and call that "savings." Usually, there's nothing left. Kakeibo flips the order — you decide how much you want to save first, before you spend a single rupee that month.

IncomeFixed costsSavings goal=What you can spend

Fixed costs are the bills you can't avoid — rent, insurance, a phone plan. Once you subtract those and your savings goal from your income, whatever remains is genuinely yours to spend for the rest of the month, without guilt.

How it differs from a budgeting app

Most budgeting apps show you what you already spent, after the fact. Kakeibo makes you decide your savings goal before you spend anything, and has you write each expense down — a small extra effort that keeps you paying attention. It's less about automation and more about noticing.

Frequently asked questions

What does "kakeibo" mean?

Kakeibo literally means "household financial ledger" in Japanese.

How much money can I save with kakeibo?

The method's own long-standing estimate is 20–30% of monthly spending, though results vary by person and how consistently you track.

Do I have to write it by hand?

The original method uses a paper notebook. Digital versions, like this app, follow the same structure while keeping the same daily habit at the center.

Is kakeibo good for beginners?

Yes — it doesn't require any financial knowledge. You just decide a savings number and write down what you spend.

Kakeibo basics

The Four Kakeibo Categories, Explained

The categories aren't really about what you bought — they're about why you bought it. Each one is built to catch a different kind of spending you'd otherwise talk yourself out of noticing.

Essentials (必需) — things you'd buy even being strict with yourself

Groceries, transport, medicine, the phone bill — the things that keep life running. The point of tracking this bucket isn't to shrink it to zero, it's to catch creep: essentials quietly grow over time without ever feeling like a decision.

Optional (任意) — deliberate wants

Clothes, shoes, gifts, a taxi instead of the bus. Things you chose, and could have skipped without your life falling apart. This is the bucket most people already think of as "discretionary spending."

Culture & leisure (娯楽) — the spending people don't notice

Restaurants, coffee, movies, a work lunch bought instead of packed from home. This gets its own column on purpose, because it's psychologically invisible — a coffee here, a delivery order there — none of it registers as "shopping," so it keeps bleeding money while people cut clothes and gadgets instead.

Unforeseen (不測) — the shock absorber

Repairs, medical bills, replacing a broken phone. Track this bucket for a full year and it stops looking unforeseen — something in this category happens almost every month, just never the same thing twice.

When something could fit two buckets

Ask: was this a routine necessity, a choice you made for yourself, a choice you made for enjoyment, or a rare one-off? That question sorts almost anything correctly, even purchases the categories don't obviously cover.

What are the four kakeibo categories?

Essentials, optional spending, culture & leisure, and unforeseen expenses.

Kakeibo basics

How Kakeibo's Weekly and Monthly Rhythm Works

Three nested rhythms — daily entries, weekly checkpoints, a monthly close — and each layer catches something the others miss.

The daily habit

Every night, or at least a couple of times a week, you write down what you spent and which category it belongs to. Daily is ideal; twice a week is the realistic floor — any less and you're relying on memory instead of receipts, and the numbers get soft.

The weekly "wallet"

At the start of the month you have a wallet — your full disposable budget. Week one spends out of it directly. Week two doesn't start over: it starts with whatever week one left behind. A monthly total only tells you what happened after it's too late to change anything; a weekly wallet tells you, mid-month, exactly how much is left while there's still time to adjust.

The monthly close

At month's end, the four weekly totals get rolled up by category. Utility bills and any big one-off purchases are tracked on their own line, so they don't distort the normal week-to-week pattern. Then: money you had to spend, minus what you actually spent, equals what you saved — followed by two honest questions: what stood out this month, and what would change next time?

How often do I need to update kakeibo?

Ideally every day. At minimum, twice a week — any less often and the numbers stop being reliable.

Kakeibo basics

The Kakeibo Annual Review: What a Full Year Reveals

A single expensive month might just be bad luck. If the same thing shows up every month, that's not an anomaly anymore — and you can only see the pattern by looking at twelve months side by side.

A year, by category

Lay out all twelve months' category totals side by side, and ask which month was hardest and which was easiest — and why. The "why" matters more than the number: a hard month from a one-off medical bill teaches nothing, but the same overspending category three months running tells you exactly where to focus.

Turning totals into shape

Work out what percentage of the year's spending each category represents. "Essentials were 45% of everything" invites a question raw rupee totals don't: does that feel right, or high? Is there a category you'd honestly like to spend more on?

The surprises that keep happening

Big one-off purchases collected across a year, with a monthly average, usually reveal that "unforeseen" isn't unforeseen at all — something notable happens almost every month. That's the moment to start a sinking fund for it in advance, instead of being blindsided each time.

Your results

The close of the year is deliberately not just a number: how much you saved, month by month against plan, what you learned, and — importantly — what you'll actually do with what you saved. Kakeibo isn't discipline for its own sake; it exists so you get to decide, on purpose, what your money buys you.

Kakeibo basics

10 Kakeibo Habits That Actually Stick

The ledger tells you what happened. These habits are what keep you using it long enough for that to matter.

  • Set one specific, time-bound goal. "Save more" doesn't work. "Save 5% of every paycheck" does — you can check it, and know when you're done.
  • Don't count on gifts of fate. Bonuses, inheritance, tax refunds — never in the budget math. Only plan around money you're actually likely to earn.
  • The 10-second rule. Reaching for something unplanned, stop and ask "why am I buying this?" If you can't answer convincingly, put it back.
  • The 30-day rule. For bigger purchases, write it down and wait 30 days. Most of the time, the wanting fades on its own.
  • Pay cash for daily discretionary spending. Handing over physical money registers as a loss in a way tapping a card doesn't.
  • Cut recurring indulgences gradually, not all at once. Swap a weekly treat for a monthly one rather than cancelling everything — it sticks better.
  • The piggy bank, literally. Spare change into a jar, only opened when full. The amounts genuinely surprise people.
  • Allow yourself small, planned indulgences. A system that demands total restriction is a system people abandon.
  • Talk to people close to you about your goals. Having someone who knows what you're working toward makes the plan easier to actually follow.
  • Don't spiral over one bad decision. Ten good choices and one bad one is still mostly good choices — understand why it happened, then move on.

Sinking Funds: How to Stop Being Surprised by Money

Car repairs, annual renewals, a friend's wedding — none of these are truly unpredictable. They're just irregular. Treating "irregular" like "unpredictable" is what makes them feel like emergencies.

What a sinking fund actually is

A sinking fund is money set aside a little at a time, on purpose, for a specific future expense you know is coming eventually — even if you don't know exactly when. Instead of paying ₹12,000 in one painful hit when the insurance renewal lands, you set aside ₹1,000 a month and barely notice it.

Kakeibo already points at this

Kakeibo's own "unforeseen" category and its year-end "significant expenses" table are doing exactly this kind of pattern-finding manually. Track a full year and it becomes obvious: something notable happens almost every month. That list is the starting point for your sinking funds — you don't need to guess, you already have a year of evidence.

Setting one up

Pick one recurring irregular cost, estimate its yearly total, divide by twelve, and set that amount aside every month — ideally into an account you don't touch for anything else. Start with just one. The goal isn't to fund everything at once, it's to stop being caught off guard by the thing that already happens every year.

Personal finance

Envelope Budgeting vs Kakeibo: What's the Difference?

Both are old, both work by splitting money into buckets before you spend it, and both are more about behavior than maths. Here's where they actually diverge.

How envelope budgeting works

You divide cash into labeled envelopes — groceries, entertainment, transport — at the start of the month. When an envelope is empty, spending in that category stops until next month. It's mechanical, visual, and effective largely because running out of physical cash is a hard, undeniable stop.

Where kakeibo goes further

Kakeibo starts the same way — money divided into categories before you spend — but adds two layers envelope budgeting doesn't have: a weekly running "wallet" that shows you exactly where you stand mid-month, and a written reflection at the end of every month asking what happened and why. Envelope budgeting tells you when you've run out. Kakeibo also asks why, and what you'll do differently.

Which one fits better

If cash-in-hand is the only thing that stops you from overspending, envelope budgeting's hard physical limit is hard to beat. If you want to actually understand your habits over time, not just cap them, kakeibo's reflection layer is the part worth the extra few minutes a week.

Pay Yourself First: The Habit That Makes Saving Automatic

Most people save whatever's left after spending, which usually means nothing. Flip the order — save first, spend what's left — and saving stops depending on willpower.

Why the order matters

Money sitting visibly in a spending account tends to get spent, a little at a time, until it's gone — not through one big decision, but through dozens of small reasonable-seeming ones. Money moved out first, before spending starts, never gets the chance to be nibbled away.

It's already built into kakeibo

This is exactly why kakeibo's formula subtracts the savings goal before calculating what you're allowed to spend, instead of treating savings as whatever survives the month. The structure does the willpower's job for you — by the time you start spending, the saving decision is already made.

Making it truly automatic

The habit gets stronger the less you have to remember to do it — a standing instruction that moves savings out right when income arrives removes the daily decision entirely. Kakeibo's own advice fits here too: keep that money somewhere you'll genuinely forget about until you need it.

Personal finance

The 50/30/20 Rule, Explained Simply

A rough ratio for splitting income — no tracking, no categories, just a gut-check on whether your spending is roughly in proportion.

The rule itself

Roughly 50% of income to needs, 30% to wants, and 20% to savings and debt repayment. No daily logging required — just check, once, whether your spending is in that general range.

What it's good for

It's fast. If someone has never looked at their spending in ratio terms before, it's a useful first gut-check — a five-minute sanity test rather than a full system.

Where it falls short

It's too coarse to actually change behavior, because it never asks why. It also lumps "eating out" into the same 30% bucket as "new clothes," which hides exactly the kind of invisible, easy-to-miss spending that kakeibo's culture & leisure category exists to expose. A ratio tells you the size of the problem, not its shape.

How it compares to kakeibo

Think of 50/30/20 as a thermometer and kakeibo as a full check-up. The ratio is a fine place to start noticing something's off; kakeibo's daily tracking and monthly reflection are what actually tell you what to do about it.

PPF (Public Provident Fund), Explained Simply

A 15-year government-backed savings account with tax-free interest and a tax deduction on the way in — the closest thing India's tax code offers to a guaranteed, risk-free long-term saver.

What it actually is

PPF is a savings account you open at a bank or post office, backed by the government, with a fixed 15-year tenure. The interest rate is set by the government each quarter, so it moves slowly and predictably rather than tracking the stock market. Contributions (up to the annual limit, currently ₹1.5 lakh) qualify for a deduction under Section 80C, the interest earned is tax-free, and the maturity amount is tax-free too — what's often called "EEE" (exempt-exempt-exempt) tax status, one of the few instruments in India that gets it.

The 15-year lock-in is the whole point

Partial withdrawals are allowed from the seventh year, and the account can be extended in five-year blocks after maturity — but the core design is deliberately illiquid. That's not a flaw to work around; it's what makes PPF a genuine long-term instrument (a child's education, a retirement cushion) rather than a place to park money you might need next year. If near-term liquidity matters more than the tax benefit, PPF is the wrong tool, not an under-optimized one.

Where it fits with kakeibo

Kakeibo tells you how much to save before you spend; PPF is one honest answer to "where does that saved money go" for the portion you won't touch for years. It pairs naturally with the Savings Goal figure on the Dashboard — decide the number first, using the method, then route part of it here once you've confirmed it's genuinely long-horizon money.

Frequently asked questions

What's the PPF tenure?

15 years from account opening, extendable afterward in blocks of five years.

Can I withdraw from PPF before 15 years?

Partial withdrawals are allowed from the seventh financial year onward, subject to rules on how much. Full withdrawal before maturity is only permitted in specific circumstances like medical emergencies.

Is PPF interest taxable?

No — interest earned and the maturity amount are both exempt from tax, alongside the Section 80C deduction on contributions.

India finance

EPF (Employee Provident Fund), Explained Simply

If you're salaried in India, you're probably already saving for retirement without noticing — a slice of every paycheck, matched by your employer, has been going into this account the whole time.

How the money actually moves

Both employee and employer contribute a percentage of basic salary (historically 12% each) every month. The employee's full share goes into the EPF account; part of the employer's share is redirected into the Employees' Pension Scheme (EPS), a separate pension component. EPFO, the government body running this, declares an interest rate annually. None of this requires you to do anything — it's payroll-automatic, which is exactly why most people can't say what their EPF balance actually is.

VPF: the same account, your choice to add more

Voluntary Provident Fund lets you contribute above the mandatory percentage into the same EPF account, at the same government-declared interest rate. It's one of the simplest ways to save more without opening anything new — the infrastructure already exists on your payslip.

Where it fits with kakeibo

EPF is a rare case where the "pay yourself first" principle kakeibo is built around already happens automatically, before the money ever reaches a bucket you'd track. Worth knowing it's there so the Income figure in Monthly Setup reflects take-home pay, not the pre-EPF number — and so retirement doesn't quietly fall out of the savings conversation just because it's invisible.

Frequently asked questions

Can I withdraw my EPF before retirement?

Partial withdrawals are allowed for specific reasons (home purchase, medical emergencies, a wedding), and full withdrawal is generally permitted after two months of unemployment, though early withdrawal has tax consequences.

What's the difference between EPF and EPS?

EPF is the provident-fund savings component; EPS is a linked pension scheme that part of the employer's contribution feeds into, paying out as a monthly pension after retirement rather than a lump sum.

India finance

NPS (National Pension System), Explained Simply

A voluntary, market-linked retirement account with a tax deduction that PPF and ELSS can't offer — an extra ₹50,000, on top of the usual 80C limit.

What makes it different from PPF

Unlike PPF's government-fixed rate, NPS money is invested across equity, corporate debt, and government bonds in proportions you largely choose, so returns move with the market rather than being guaranteed. It's a genuinely different risk profile aimed at the same job — long-horizon retirement saving — not a safer version of the same thing.

Tier I vs Tier II

Tier I is the actual retirement account: contributions are locked in until retirement age, with structured partial-withdrawal rules along the way, and this is the account that carries the tax benefits. Tier II is an optional, more liquid add-on account with no lock-in and no tax benefit of its own — useful only once Tier I is already funded.

The deduction PPF and ELSS don't have

Beyond the usual Section 80C ceiling, NPS contributions get an additional deduction of up to ₹50,000 under Section 80CCD(1B) — genuinely extra room, not a reshuffling of the same 80C limit other instruments compete for.

Where it fits with kakeibo

If the Savings Goal on the Dashboard already has a slice earmarked "long-term, don't touch," NPS is worth knowing about specifically because of that extra deduction — it's one of the few places additional saving translates into additional tax benefit, not just the same 80C room split differently.

Frequently asked questions

Is NPS safe?

It carries market risk since a portion is invested in equity, but the equity allocation is capped and typically reduces automatically as you approach retirement age, depending on the option chosen.

When can I withdraw from NPS?

At retirement (60), a portion can be withdrawn as a lump sum, and the rest must be used to purchase an annuity that pays a regular pension. Partial withdrawals before that are allowed only for specific, limited reasons.

India finance

ELSS (Equity-Linked Savings Scheme), Explained Simply

A tax-saving mutual fund with a 3-year lock-in — the shortest of every Section 80C option, and the only one that puts your money in the stock market instead of a government-fixed rate.

What it is

ELSS funds are ordinary equity mutual funds with one structural difference: contributions qualify for the Section 80C deduction, and in exchange, each individual investment is locked in for three years. Because it's an equity fund, returns aren't guaranteed and can be negative over short periods — the tradeoff for the shortest lock-in among 80C instruments is that you're actually taking market risk, not a discount on a safe product.

Why the 3-year lock-in changes the calculation

PPF locks money up for 15 years; ELSS for 3. That difference matters less for the tax deduction itself (both qualify equally) and more for what kind of goal the money is actually for — ELSS suits a saver who wants 80C benefits without giving up market-linked growth, and who can tolerate a fund's value moving during those 3 years without needing to touch it.

ELSS vs PPF, the honest tradeoff

PPF: government-guaranteed rate, 15-year lock-in, zero market risk. ELSS: market-linked returns that have historically outpaced PPF over long periods, 3-year lock-in, real risk of loss in a bad stretch. Neither is strictly better — it's a risk-tolerance question dressed up as a tax question, and most people benefit from knowing that before picking one to fill their 80C limit.

Where it fits with kakeibo

This is squarely a decision for the portion of the Savings Goal already earmarked long-term, not the weekly buckets — kakeibo's daily tracking doesn't change once the money's routed here; it only changes how quickly you'd want to check on it, since equity funds move.

Frequently asked questions

Is the ELSS lock-in per investment or per account?

Per investment. Each SIP installment or lump sum has its own 3-year lock-in counted from its own investment date, not from when the account was first opened.

Can I lose money in ELSS?

Yes — it's an equity investment, and the value can fall, including below what was originally invested, particularly over shorter stretches within the lock-in.

India finance

Sukanya Samriddhi Yojana, Explained Simply

A government savings scheme built specifically for a girl child's education or marriage, with one of the highest fixed interest rates of any small-savings instrument in India.

Who it's for and how it starts

The account can be opened by a parent or legal guardian for a girl child before she turns 10, at a bank or post office, with a modest minimum deposit. Only one account per girl child is allowed, and a family can open accounts for up to two girl children (with an exception for twins/triplets in the second birth).

The contribution and maturity timeline

Deposits are required for 15 years from account opening, but the account continues earning interest until it matures 21 years after opening (or on the girl's marriage after age 18, if earlier) — so contributions stop well before the money is actually needed, which is worth planning around rather than discovering later. Contributions qualify for the Section 80C deduction, and like PPF, interest and maturity proceeds are tax-free.

Partial withdrawal for education

Up to 50% of the balance can be withdrawn once the girl turns 18 (or completes 10th grade, whichever is earlier) specifically for education expenses — a built-in acknowledgment that "22 years away" and "her education starts now" are both true at once.

Where it fits with kakeibo

This is a rare instrument with the goal already built into the name. It slots naturally into the Goals and Intentions step at Monthly Setup — a long-horizon, purpose-specific line under "how will you actually achieve that," distinct from the general Savings Goal number.

Frequently asked questions

By what age must a Sukanya Samriddhi account be opened?

Before the girl child turns 10 years old.

When does the account mature?

21 years after the account was opened, or upon the girl's marriage after she turns 18, whichever comes first.

India finance

Section 80C vs 80D: The Two Deductions People Mix Up

80C covers where you save. 80D covers what you insure. They're separate limits, not one pool — maxing out 80C does nothing for 80D, and vice versa.

Section 80C: savings and specific spends

80C bundles a wide range of instruments and payments under one combined annual limit (currently ₹1.5 lakh): PPF, EPF, ELSS, Sukanya Samriddhi, life insurance premiums, principal repayment on a home loan, and children's tuition fees, among others. They all draw from the same ₹1.5 lakh ceiling — putting ₹1.5 lakh into PPF alone already exhausts the limit for every other 80C option that year.

Section 80D: health insurance premiums

80D is a separate deduction for health insurance premiums, with its own limit for self and family, and typically a higher limit for premiums paid for senior-citizen parents. This has nothing to do with the 80C bucket — a family fully using 80C on PPF and ELSS can still claim 80D in full on top of it.

Why the distinction actually matters

The common mistake is treating "tax saving" as one undifferentiated pool and stopping once something, anything, has been claimed. Since 80C and 80D are genuinely separate ceilings, the real optimization question is two questions: have you used the 80C limit efficiently, and separately, is your family's health insurance actually adequate, not just present.

Where this fits with kakeibo

Health insurance premiums are the textbook Essentials (必需) entry — unglamorous, easy to underfund because nothing bad has happened yet. Kakeibo's own logic (track the boring necessary things precisely because they're boring) applies as much to 80D as it does to groceries.

Frequently asked questions

Can I claim both 80C and 80D in the same year?

Yes — they're independent limits. Fully using one has no effect on what's available under the other.

Does life insurance count under 80C or 80D?

Life insurance premiums fall under 80C. Health insurance premiums fall under 80D.

India finance

CIBIL Score, Explained Simply

A three-digit number from 300–900 that quietly decides two things about every loan you'll ever apply for: whether you get approved, and what interest rate you're offered if you do.

What actually moves the number

Payment history carries the most weight — on-time EMIs and credit card bills matter more than almost anything else. Credit utilization (how much of your available credit you're actually using), the length of your credit history, the mix of loan types, and how often you apply for new credit all factor in too. A score above roughly 750 is generally considered good; lenders use their own cutoffs beyond that.

Why it matters specifically for EMIs

A better score doesn't just improve approval odds — it directly affects the interest rate a lender offers, and the EMI Calculator's math makes that concrete: the same ₹5,00,000 loan at 9% instead of 12% is a meaningfully lower monthly payment and a much smaller total-interest number over the loan's life. A few points on a credit score can be worth more over five years than most rate-shopping between lenders.

The mistakes that quietly hurt it

Maxing out credit cards even if paid off monthly, closing old credit accounts (which shortens credit history), applying for several loans or cards in a short window, and missing even one EMI payment all move the number in the wrong direction — often more than people expect.

Where this fits with kakeibo

The weekly buckets and the EMI tracker exist partly to make sure EMIs actually get paid on time, every time — which is exactly the single biggest factor in this score. A missed payment tracked nowhere is a CIBIL hit nobody saw coming.

Frequently asked questions

What is a good CIBIL score?

Generally, 750 and above is considered good by most lenders, though exact cutoffs vary by lender and loan type.

Does checking my own CIBIL score lower it?

No — checking your own score is a "soft inquiry" and doesn't affect it. Only "hard inquiries," triggered when a lender checks your score for a loan application, can have a small impact.

Budgeting method

Changes what Add an Entry and Weekly buckets track on the Dashboard. Existing entries and EMIs are relabeled to fit the new categories, not deleted — switching back won't perfectly restore the originals.

These UPI IDs never sync to the cloud, here or in any real build — only balances and category totals would ever leave this device, nothing that identifies a real account. On this device, they're encrypted at rest and masked until you unlock with your device's own authentication (Windows Hello, Touch ID, Face ID, or Android biometric/screen-lock) — or a PIN, only as a fallback when this browser or device can't do that — see the Trust panel on the Home page for what that protects against.

A lock-screen or home-screen widget plus a Shortcuts / App Intents action — tap a category, type an amount, done — no need to open the app. Planned for the mobile build.

Tool

Free EMI Calculator

Work out the monthly payment on a loan in seconds. An EMI is really just another fixed cost in a kakeibo budget — calculate it here, then track it so it's subtracted from your disposable income automatically every month, exactly like Fixed costs, until the loan is paid off.

50/30/20 Budget Planner

Split your monthly income into needs, wants, and savings in one step — a five-minute gut-check on proportion, not a replacement for daily tracking.

A ratio tells you the size of a problem, not its shape — it can't tell “eating out” from “new clothes,” which is exactly what kakeibo's four categories are for. Use this for a quick sanity check; use the Dashboard when you want to actually change something.

Tool

Emergency Fund Calculator

Work out how big a cash buffer you actually need, and how long it'll take to build one — so an unforeseen expense stays unforeseen instead of becoming a crisis.

3–6 months is the usual range for steady salaried income; freelance or irregular income leans toward 6–12. This is exactly what kakeibo's Unforeseen (不測) category is for — a fund sized right means a burst pipe or a hospital bill stays a line item, not a crisis.

Dec was hardest — holiday spending across optional and culture. Jan was easiest — a deliberate pullback right after.
