The Resto Method
A Kakeibo notebook adapted for how people actually live — with multiple bank accounts, credit cards, and income that doesn't always arrive on schedule.

The Core Idea
Kakeibo is a Japanese method from 1904. A household would sit down with a physical notebook, record what came in, record what went out, and reflect on whether their money went toward things that mattered to them. No forecasts, no guilt, no complexity.
Resto is that notebook, adapted for how people in Mexico actually live — with multiple bank accounts, credit cards, digital wallets like Mercado Pago, and income that doesn't always arrive on a fixed schedule.
Setup
Record your income sources
Add every source of money that comes into your life. Be honest and conservative — if your side income is irregular, enter the minimum you reliably receive.
- What it is (paycheck, freelance, rental income)
- The amount
- How often it arrives (weekly, biweekly, semimonthly, monthly)
Resto converts everything to a daily number. That number is your daily allowance — the single most important figure in the app.
Record your fixed expenses
These are the things you've already committed to paying. Rent, car insurance, Netflix, phone bill, gym membership, annual software subscriptions. Everything you'd have to actively cancel to stop paying.
- What it is
- The amount
- How often you pay it (monthly, annual, semiannual, one-time)
Be thorough. The most common setup mistake is forgetting infrequent but large payments — car insurance paid twice a year, annual subscriptions, holiday travel.
What percentage of your income is committed to fixed expenses
Your true daily allowance
If your fixed expenses exceed 50% of income, that's the first thing worth addressing — before anything else.
Record your account balances
Add each account where your money lives.
- Checking account
- Credit cards
- Digital wallets
- Savings accounts
For each account, enter the current balance from your actual bank app. For credit cards, enter what you currently owe. These balances don't update automatically — you update them manually. Resto isn't a real-time dashboard. It's a reflection tool.
Daily Life
The only habit that matters
Every time you spend money on something discretionary — coffee, lunch, clothing, a taxi, anything that wasn't already committed — open Resto and add a transaction.
- Amount
- What it was
- Category (almost always Discretionary)
The goal is under 10 seconds per entry.
Why this matters
The Kakeibo method only works if you record spending close to when it happens. Trying to reconstruct a week of transactions from memory on Sunday night is exhausting and inaccurate. Thirty seconds in the moment is the whole practice.
The four transaction categories
Discretionary
You chose to spend this
Coffee, dinner, clothing
Fixed Expense
A committed expense you paid
Rent, phone bill
Account Transfer
Money moving between your accounts
Paying credit card from checking
Extra Income
Unexpected money in
A refund, a small freelance job
Most of your day-to-day entries will be Discretionary. The others exist to keep the spending picture accurate.
The Account Transfer rule
When you pay your credit card bill from your checking account, you need to do two things:
- 1 Add the payment as a transaction, categorized as Account Transfer. This ensures the payment doesn't inflate your apparent discretionary spending.
- 2 Update your credit card balance manually in the Accounts tab. This keeps your Today tab accurate.
Both steps matter. The transaction records the movement. The balance update reflects the new reality.
Weekly Reflection
This is the heart of Kakeibo. Not the daily tracking — the weekly pause.
Open the Reflect tab and look at the last seven days. Ask yourself four questions:
How much did I have available?
Your daily allowance multiplied by seven. This is your budget for the week — not a category-by-category breakdown, just one number.
How much did I actually spend?
The total discretionary spending Resto recorded.
Where did it go?
Look at the top merchants and the daily spending chart. Was there a day that surprised you? A merchant you forgot about?
Does that feel right?
Not 'was I over or under budget' — that framing creates guilt. The real question is whether the money went toward things that were actually worth it to you.
A week where you spent $300 on a meaningful trip with friends is a good week. A week where you spent $300 and can't remember on what is the thing worth examining.
Write nothing down. No action items required. Just look at it honestly for five minutes.
Monthly Reset
Update your account balances
Open each of your banking apps and update the balances in Resto. This keeps the Today tab's cash status calculation meaningful.
Check the Today tab
The cash status shows you:
Checking balance
minus credit card debt
minus one month of fixed expenses (your safety buffer)
= surplus or deficit
A surplus means you have breathing room.
A deficit means you're spending ahead of your income and something needs to change.
Look at the upcoming fixed expenses
The next 30 days of committed payments are listed. If a large infrequent expense is coming — car insurance, an annual subscription — you can see it before it hits and plan accordingly.
Annual Review
Go back to your income sources and fixed expenses and update them. Things change:
- Did you get a raise?
- Did you add or cancel subscriptions?
- Is your rent different?
- Are there annual expenses you forgot to add last year?
This recalibrates your daily allowance for the year ahead.
What Resto is not for
Not a forecasting tool
You don't set spending targets per category. You don't predict how much you'll spend on groceries next month. Those predictions are almost always wrong and create anxiety without improving behavior.
Not a replacement for checking your bank apps
You still need to open your banking apps regularly. Resto is a layer of reflection on top of that, not a substitute for it.
Not about optimizing every purchase
The daily allowance gives you freedom within a number. If you're under your allowance, spend without guilt. The method only asks you to notice when patterns emerge that don't match your values.
Managing finances with a partner?
Resto supports households -- two people managing money together with shared visibility and personal privacy.
The one thing that makes it work
Record transactions when they happen.
Everything else — the weekly reflection, the monthly reset, the annual review — depends on having accurate data. And accurate data comes from the habit of the thirty-second entry.
