Monthly Budget Calculator
Add up what comes in and what goes out each month, and see exactly what’s left.
Edit, add or remove any line. Bills can be entered weekly, monthly, quarterly or yearly and are converted to a monthly figure. Your figures stay in this browser tab — nothing is saved or sent.
Your monthly budget
Where your money goes
Each spending and savings line as a monthly amount and as a share of your income.
Monthly and yearly totals
Helpful for annual bills and for seeing how small monthly amounts add up over a year.

How to use this budget calculator
Start with the money you actually receive — take-home pay after tax, pension and student loan, plus any other regular income such as benefits, maintenance or rent from a lodger. Then list what goes out. Every line can be renamed, removed or added to, so the categories can match the way you think about your own spending.
Bills that aren’t monthly
Choose how often each amount is paid and the calculator converts it to a monthly equivalent: weekly amounts are multiplied by 52 and divided by 12 (so £80 a week is £346.67 a month, not £320), quarterly amounts are divided by 3 and yearly amounts by 12. Spreading annual costs such as car insurance, TV licence or Christmas across the year avoids a budget that only works in months without big bills.
What the figures mean
- Spending is everything except the lines in the Savings group.
- Left over is income minus spending minus savings. A negative figure is a shortfall: more is going out than coming in.
- Savings rate is your savings as a share of your income. The calculator also shows what the rate would be if any money left over were saved too.
About budgeting rules of thumb
You may come across rules such as putting 50% of income towards needs, 30% towards wants and 20% towards savings. They can be a useful prompt, but they’re not a standard everyone should meet — housing alone can take more than half of take-home pay in parts of the UK, and the right balance depends on your income, commitments and goals. This calculator shows where your money goes without judging it against a fixed formula.
If your budget shows a shortfall
A shortfall that’s covered by borrowing tends to grow over time. If you’re struggling to keep up with bills or debt repayments, free and confidential help is available — MoneyHelper can point you to free debt advice services near you or online.

Frequently asked questions
Should I use my gross salary or take-home pay?
Take-home pay — the amount that actually reaches your bank account after tax, National Insurance, pension and student loan. If you are not sure what that is, the UK Take-Home Pay Calculator on this site can estimate it.
How do I budget for annual or irregular bills?
Enter them at the frequency you pay them — for example yearly for car insurance — and the calculator converts them to a monthly amount. Setting that monthly amount aside means the money is there when the bill arrives.
What is a good savings rate?
There isn’t one figure that suits everyone. It depends on your income, essential costs, debts and what you are saving for. The savings rate here is a way to track your own progress rather than a target set by the calculator.
Is my budget saved anywhere?
No. The figures exist only in this browser tab while the page is open. Nothing is stored on your device or sent to our servers, so reloading the page resets it to the example figures.
