How to Make a Monthly Budget in the UK (Step by Step)

A monthly budget is simply a plan for your money: what comes in, what goes out, and what is left. It does not need special software or a finance degree. This guide shows you how to make a monthly budget in the UK step by step, using pounds and the kind of bills most UK households actually have, from council tax to the TV licence.

Why make a monthly budget?

Most people are paid monthly in the UK, and most big bills (rent or mortgage, council tax, energy, phone) are monthly too. A monthly budget lines up with that rhythm. It helps you:

Step 1: Work out your monthly income

Start with what actually lands in your bank account, your take-home pay after tax, National Insurance, pension contributions and any student loan repayments. Your payslip shows this as "net pay".

Add any other regular income, such as:

If your income changes from month to month (for example with shift work or self-employment), look back over the last few months and use a cautious figure, nearer the lower end, so that you are not caught short in a quieter month.

Step 2: List your fixed bills

Fixed bills are the costs that are roughly the same every month and usually go out by direct debit or standing order. Go through your bank statements and write down each one. Common UK examples include:

Do not forget annual costs. If you pay something once a year, such as car insurance or a subscription renewal, divide it by twelve and include that amount as a monthly figure. Putting this aside each month means the bill is not a shock when it arrives.

Step 3: Estimate your variable spending

Variable costs change from month to month. These are where budgets usually go wrong, because they are easy to underestimate. Typical categories are:

The most accurate way to estimate these is to look at the last two or three months of bank and card statements and add up what you really spent in each category. It can be eye-opening. Alternatively, track every purchase for one month with an expense log.

Step 4: Add savings as a "bill"

If you wait to save whatever is left at the end of the month, there is often nothing left. Instead, treat savings as a bill and pay yourself first, ideally by setting up a standing order to a savings account on pay day.

Useful savings pots to consider:

Even a small amount each month builds the habit, and you can increase it later.

Step 5: Do the maths

Now take your monthly income and subtract your fixed bills, variable spending and savings.

A simple framework: needs, wants and savings

If you like a rule of thumb, the "50/30/20" approach is popular: roughly half of take-home pay for needs, about a third for wants and a fifth for savings and extra debt repayments. It is only a guide. With UK rents and living costs, many households find that needs take up much more than half, and that is fine. The point is to make conscious choices, not to hit exact percentages.

Step 6: Track and review each month

A budget is not a one-off exercise. Set aside fifteen minutes at the end of each month (or on pay day) to:

  1. compare what you planned with what you actually spent
  2. note any categories that went over and why
  3. adjust next month's plan
  4. check upcoming one-off costs such as birthdays or renewals

Writing it down helps. Our printable Monthly Budget Tracker UK is designed in pounds sterling, with pages for income, bills, savings, debt and an expense log, so you can keep everything in one folder and see the year build up.
