How to plan a monthly budget

A simple rule-of-thumb budget is the 50/30/20 rule: around 50% of take-home pay on essentials, 30% on wants, and 20% on savings and debt repayments. This calculator lets you see how your numbers compare.

Enter your monthly income and how much you currently spend in each category. Use the leftover figure and savings rate to decide whether you need to reduce spending or increase savings to hit your financial goals.

Example budget

With £2,800 take-home income, you might allocate £1,600 to essentials (57%), £400 to wants (14%), £500 to savings (18%) and £200 to extra debt repayments (7%). This leaves £100 unallocated that you can keep as a buffer.
