How to actually run the ledger
The method takes ten minutes to understand and a month to get right. These are the places it gets difficult: sorting a receipt, a card that spends before you do, a month that does not arrive, and the reflection nobody quite knows how to write.

Starting a ledger
Day one, the calendar boundary people actually start on, and what goes in which envelope.
- You are holding a receipt that fits two envelopesThe four kakeibo categories explainedA working list of everyday expenses sorted into each envelope, with the awkward cases argued out rather than avoided.8 min
- You have never kept a ledgerHow to start kakeibo: your first month, step by stepDay one setup, a first week where nothing gets trimmed, and what to do when week three slips.9 min
- You are starting on the first of the monthThe kakeibo January reset: a 31 day planA dated plan for the month everybody already searches for a fresh start, including closing December out first.9 min
- You cannot tell a need from a wantNeeds versus wants in kakeibo: settling the cases the categories do not settle themselvesFour tests that settle a borderline expense, and why a rule you can repeat beats a rule that is right once.9 min
Running the month
The arithmetic before the month and the writing after it.
- The month is over and you have to write somethingThe four kakeibo questions, and prompts for the weekly and monthly reviewThe four questions in the order the method asks them, a weekly check, and prompts you can answer in fifteen minutes.6 min
- You want a number, not a percentageHow much should you save each month? The arithmetic, not a borrowed percentageNo agency publishes a recommended rate. Work the figure from your own income and your own Survival costs instead.9 min
- New in the libraryHow much of your income should go to rent? The 30 percent rule, tracedThe 30 percent figure is a 1980s public housing rent cap, not a budgeting finding. Work your own rent share out first, then see what BLS, ONS and the ABS actually publish, and what a heavy housing share does to the rest of the month.9 min
- New in the libraryHow big should your emergency fund be? Sizing it off Survival, not incomeThree to six months of Survival, not of income, and kept apart from the Extra envelope that already absorbs the ordinary shock. The arithmetic for both, worked through to a monthly figure.8 min
- New in the libraryHow to calculate your savings rate, and what the number actually depends onThe formula is one division, saved over take home pay. What actually moves the answer is three quiet decisions: gross or net, whether debt counts, whether an employer contribution counts, worked through on one household both ways.9 min
- New in the libraryWhat the average household actually spends, sorted into the four envelopesThe US Bureau of Labor Statistics, the UK Office for National Statistics and the Australian Household Spending Indicator, read carefully rather than skimmed, and sorted into Survival, Optional, Culture and Extra.9 min
- You want to know what this costs you in timeHow much time does kakeibo actually take?Seconds at the counter, minutes at the weekly check, and one longer sitting at the end of the month.8 min
- New in the libraryHow much should you spend on groceries? The data, split into the shop and the takeawayThe US Bureau of Labor Statistics puts food at 12.9 percent of average household spending, split into what is cooked at home and what is not. The UK and Australian data cannot give a comparable total, and this guide says so, then argues where a grocery bill actually moves.8 min
- New in the libraryHow much should you spend on transport? The running cost the repayment leaves outThe US Bureau of Labor Statistics prices the gap: gasoline, other vehicle expenses and public transportation together outweigh what the average household spends on buying the car in the first place. Where transport sits in Survival, and one worked comparison between running a car and not.9 min
- A charge keeps renewing and nobody decided that againThe subscription audit, done once and then keptEvery recurring charge at its annual cost, sorted into Optional and Culture, and reviewed on a date rather than a whim.8 min
- New in the libraryKakeibo for families with children: the costs that arrive with no noticeThe school notice, the season's sports kit and the birthday season all belong in the same envelope. Where children's costs sit inside the four categories, and what changes in the monthly reflection once they are in the house.9 min
When the month is difficult
Where the method breaks down for somebody, which is where the writing has to be best.
- The money moves before you doHow to do kakeibo with a credit card and digital paymentsCards, subscriptions, and the lag between the decision and the money actually leaving.5 min
- Two people, one householdKakeibo for couples: one ledger, not twoOne ledger rather than two, and a reflection run as a conversation rather than an audit.8 min
- Survival takes most of itKakeibo on a low income, and when payday is the whole planWhen there is nothing left to trim, the value is knowing the number before the month starts.8 min
- No two paydays are alikeKakeibo with irregular income, budgeting from your lowest monthPlan Survival from your lowest realistic month, then give a good month a job.8 min
- The month is already over budgetWhat to do when you blow the budget, without abandoning the ledgerRe-plan the rest of the month from what is genuinely left, rather than closing the book until the first.8 min
- A balance has to come down firstKakeibo when you are paying off debtWhere the minimum payment sits, where anything above it sits, and what the ledger is actually for while a balance is being paid down.9 min
- Your income arrives once a term, not once a monthKakeibo for students: budgeting a term, not a salaryPrice Survival against the whole term, then divide what is left by the week, with no assumption of rent, a car or a salary.9 min

The argument, and the record
What can be defended about the method, and who actually published it.
- You want to know who actually wrote itWho invented kakeibo? Hani Motoko and the history of the household ledgerHani Motoko, a magazine that was not yet called Fujin no Tomo, and the thin parts of the record left thin.7 min

- You are choosing between two systems, not starting from zeroKakeibo vs zero based budgeting: two ways to give a dollar a jobBoth insist every dollar gets a job. The difference is whether the job is decided in advance or asked about afterward.8 min
Where to start
If you have not met the method before, read what is kakeibo first. It covers the history, the four categories, the four questions and what the public spending data says about where household money actually goes, and it has the planner embedded so you can try it on your own income while you read.
If you have a number in mind rather than a method, go straight to the arithmetic. The calculators run in your browser on one page, and 294 common savings targets are already worked out per month, per week and per day.
Choosing between methods rather than learning one? The comparisons put kakeibo against the 50/30/20 rule, YNAB, physical envelopes and cash stuffing, including where each of them is the better answer.
What we publish
A guide goes up when there is a question we can answer better than the page currently ranking for it, and every one of them names the search it exists to answer before a word of it is written. None of them repeat the savings statistic that circulates in this niche without a source behind it, and the one guide that goes looking for that source is the one at the top of this page.
Reading times on this page are counted from the guides themselves at build time rather than typed in, so a guide that grows says so.
Reading about a ledger is not keeping one
The method is a month of entries and fifteen minutes of writing. The app is there to make the entries take seconds, which is the only part that ever stops people.
