A month to month budget planner that survives past week two
Most monthly budgets are abandoned somewhere around the 12th. Not because people lack discipline, but because the planner answered the wrong question. Here is the version that holds up, and a printable you can use tonight.
Why monthly budgets collapse in week two
A typical budget planner asks you to divide your income into categories: so much for groceries, so much for transport, so much for fun. You fill it in on the 1st, feeling organised. By the 12th the rent has gone out, two bills you had forgotten have landed, and the number in your account no longer resembles anything on the page.
The problem is that the plan and reality diverge immediately, and nothing in the planner tells you what to do about it. You are left with a document describing a month that is no longer happening.
A month to month planner fixes this by tracking one thing the category approach leaves out: what is already committed. Your balance is not your budget. The money for rent is sitting in your account right now, and it is not yours to spend.
The three numbers that actually matter
Every workable monthly budget comes down to three figures. Everything else is detail.
1. Income for the month
What actually arrives, after tax. If your income varies, use the lowest of the last three months rather than the average. A budget built on your best month fails in your worst one.
2. Committed money
Everything already spoken for before you make a single choice: rent or mortgage, utilities, insurance, subscriptions, loan repayments, childcare, transport passes. These are not decisions you make each month. They are obligations that happen to you.
3. Free to spend
Income minus committed, divided by the days left. This is the only number you need on a Tuesday afternoon in a shop. Not your balance, not your category allowance. What is genuinely yours today.
Most people are surprised by how small this number is the first time they calculate it honestly. That surprise is the entire value of the exercise. Nothing changes while committed money and spendable money look identical in your banking app.

How to run it each month
- On payday, not the 1st. Fill in income and committed money the day you get paid. The calendar month is an accounting convention; your money arrives on a different schedule.
- Subtract before you spend. Work out free to spend before any discretionary purchase happens that month, not after.
- Check once a week, not daily. Daily checking turns into anxiety and then avoidance. Sunday evening, five minutes, update the week row.
- Carry the mistake forward. If you overspend in week two, recalculate free to spend for the days that remain rather than declaring the month a failure. This one habit is the difference between a budget that lasts a month and one that lasts a year.
What to do when the month goes wrong
It will. A car repair, a birthday you forgot, a bill larger than expected. The planner is not there to prevent that; it is there so you find out on the day it happens instead of at the end of the month.
When it does, you have three options and it helps to name them: reduce what is left for the rest of the month, move money from savings on purpose, or let something committed slide and plan for it deliberately. Any of those is fine. Not choosing is what leaves you overdrawn.
When paper stops being enough
Paper works, and for many people it works permanently, because writing something down by hand is what makes you notice it. If that is you, print this page each month and ignore everything below.
The arithmetic is where paper strains. Recalculating free to spend after every purchase, tracking which committed bills have actually left the account, remembering that the annual insurance payment lands in March, splitting one supermarket receipt across groceries and household. Doing that by hand is what makes people quietly stop.
That is the part Wallety automates. It uses this exact method: committed money comes out first, and it shows what is genuinely free to spend today. It is private and works offline, with no account and no bank login, so the arithmetic gets easier without handing your finances to anyone.
