What Kakebo is
Kakebo (also written kakeibo, roughly “household account book”) is a Japanese method for keeping track of spending. It is the opposite of a spreadsheet full of formulas: a notebook, a few rules and the habit of writing things down and reflecting.
The method was created in 1904 by journalist Hani Motoko, so that Japanese families could manage household money more mindfully. More than a century later the idea still works, because it attacks the weak spot of almost every budget: we don’t look at what we spend.
The four Kakebo questions
The heart of the method is four questions, answered at the start and at the end of each month:
- How much money do I have? Add up the month’s income and subtract fixed bills (rent, power, internet, installments).
- How much would I like to save? Set a savings goal before you spend, not with whatever is left over.
- How much am I spending? Write down every expense on the day it happens.
- How can I improve? At the end of the month, compare the goal with the result and pick one change for the next month.
The question that makes the difference is the last one. Without it, logging expenses is just bookkeeping; with it, it becomes a habit.
The four categories
In Kakebo, every expense falls into one of four categories. They help you see what is essential and what is a choice.
| Category | What goes in | Examples |
|---|---|---|
| Survival | What you need to live | Housing, groceries, transport, health, household bills |
| Wants | What you want but could wait for | Restaurants, clothes, streaming apps, delivery |
| Culture | What feeds the mind | Books, courses, movies, museums, hobbies |
| Extra | The unexpected and the unusual | Repairs, gifts, fines, an unplanned trip |
Not sure whether something is “survival” or a “want”? Ask: if I went without this this month, would my life stop?
How to start in five steps
- Take a snapshot of the month. Write down your income and every fixed bill. What is left is your free money.
- Choose a savings goal. It can be small. What matters is deciding it before you spend.
- Log every expense the same day. Amount, description and category. It takes less than a minute, and forgetting is the main reason the method fails.
- Do a quick weekly review. Look at the total per category and check you are on plan.
- Reflect at the end of the month. Answer the four questions in writing and set one change for the next month.
Common mistakes
- Everything is “survival”. If most of your spending lands there, it is worth revisiting your criteria.
- Ignoring small purchases. Coffee, snacks and apps add up by the end of the month.
- Skipping the reflection. Without the review, you just have a bank statement by another name.
- Goals that are too big. Start with an amount you can really save and raise it little by little.
Kakebo on your phone
Many people love the notebook. Others prefer to carry the method in their pocket, with totals calculated automatically. That is why we built Kakeibow: an Android app that follows Kakebo, with the four categories, charts by category, goals and a review screen with the four questions. Your data stays only on your phone, with no account.
Kakeibow is now on Google Play: get the app and start with a 14-day free trial.
Summary
- Kakebo is writing down, categorizing and reflecting.
- Set your savings goal before you spend.
- Use the four categories: survival, wants, culture and extra.
- End every month by deciding how to improve the next one.
