How to make a monthly budget in the UK (with a free 50/30/20 example)
A budget is just a plan for your money before the month starts, so you are not guessing at the end of it. This guide walks you through making one in the UK, step by step, with a free 50/30/20 example you can copy.
Why a monthly budget works well in the UK
Most people in the UK are paid monthly, and most big bills (rent or mortgage, council tax, energy, phone, broadband) go out monthly by Direct Debit. That makes a monthly budget the natural fit: one plan per payday, matched to the bills that actually leave your account.
A budget is not about cutting out everything you enjoy. It is about deciding in advance where your money goes, so the essentials are covered, you have something put aside, and you can spend the rest without guilt.
Step 1: Work out your real monthly income
Use your take-home pay, the amount that lands in your bank account after Income Tax, National Insurance, pension contributions and any student loan repayments. Your payslip shows this as "net pay". Do not budget from your salary before deductions, because you never see that money.
- Regular pay: use the net figure from your last payslip.
- Pay that changes: if you work shifts, overtime or zero-hours, look at your last three to six months and use the lowest typical month. Anything above that is a bonus you can save or use to catch up.
- Other income: add regular money such as Universal Credit, Child Benefit or maintenance you receive. Universal Credit is paid monthly, so it fits straight in.
- Weekly or four-weekly pay: multiply weekly pay by 52 and divide by 12 to get a fair monthly average. Some months will have an extra payday; treat that as a top-up.
Step 2: List everything that goes out
Download the last two or three months of bank and credit card statements. Go through them line by line and sort each payment into one of three groups. This is the most useful hour you will spend on your money this year, because most people find at least one payment they had forgotten about.
Needs
Things you must pay to live and work: rent or mortgage, council tax, gas and electricity, water, basic food shopping, travel to work, phone, broadband if you need it for work or benefits, insurance you are required to have, childcare, and minimum payments on any debts.
Wants
Things that make life better but you could pause: takeaways and eating out, streaming services, gym memberships, clothes beyond the basics, hobbies, nights out, holidays and upgrades.
Savings and extra debt payments
Money that improves your future: an emergency fund, savings for a goal, pension top-ups, and anything you pay on debts above the minimum.
Do not forget the irregular costs: car MOT and servicing, the TV licence if you need one, birthdays, Christmas, school uniforms, annual subscriptions and glasses or dental work. Add up what they cost over a year, divide by 12 and treat that as a monthly bill you pay into a separate pot.
Step 3: Use the 50/30/20 rule as a starting point
The 50/30/20 rule is a simple way to split take-home pay:
- 50% for needs
- 30% for wants
- 20% for savings and paying off debt faster
It is a rule of thumb, not a law. With UK rents and energy costs, many people find their needs take more than half their income, especially in London and other big cities. That is fine. Use the split to see where you are, then adjust it to something like 60/20/20 or 70/20/10 that works for you right now.
A free 50/30/20 example
Here is a worked example for someone with a take-home pay of £2,000 a month. The figures are illustrative, so swap in your own.
| Category | Share | Monthly amount | Example spending |
|---|---|---|---|
| Needs | 50% | £1,000 | Rent share £650, council tax £110, energy and water £120, food shop £100, travel £20 |
| Wants | 30% | £600 | Eating out and takeaways £150, streaming and gym £45, clothes £60, social and hobbies £200, irregular costs pot £145 |
| Savings and debt | 20% | £400 | Emergency fund £200, extra credit card payment £150, holiday pot £50 |
| Total | 100% | £2,000 | Every pound has a job |
If your needs come to £1,300 instead, you have two choices: bring wants down to £400 and savings to £300, or look for ways to cut the needs themselves. Our guide to 25 ways to cut household bills in the UK is a good place to start.

Step 4: Set up your accounts to do the work
A budget is much easier to stick to when your bank accounts match it. A simple set-up that works for many people:
- Bills account: your salary lands here and every Direct Debit for needs goes out from here.
- Spending account or pot: on payday, move your "wants" money here. When it is gone, it is gone until next payday.
- Savings account: move your savings amount on payday, before you have a chance to spend it. Many banks let you set this up as a standing order.
Many UK banking apps offer free "pots" or "spaces" inside one account, which makes this easy without opening several accounts. If you can, ask your providers to move Direct Debit dates to just after payday so you never have bills leaving before your money arrives.
Some people stick to a budget better with a physical planner or a cash envelope wallet for weekly spending. See budget planners on Amazon UK (affiliate link placeholder).
Step 5: Track it for the first three months
Your first budget will be wrong, and that is normal. Once a week, spend ten minutes checking what you have actually spent against the plan. Notice which categories ran over and why. After two or three months you will know your real numbers and the budget will feel easy.
Tips that help:
- Round up, not down. If the food shop is "about £90", budget £100.
- Keep a small buffer. £20 to £50 for things you could not predict stops one surprise wrecking the month.
- Check subscriptions. Search your statements for small regular payments you no longer use.
- Plan for the big months. December, back-to-school and the month your car insurance renews will need extra. Your irregular costs pot is there for this.
What if the numbers don't add up?
If your essential spending is more than your income, a budget has done its job by showing you that clearly. The next step is to make sure you are getting all the help you are entitled to. GOV.UK lists free, independent benefits calculators that take around 15 minutes and can show support you did not know about, including help with council tax.
If you are falling behind on bills or debts, get free advice early. MoneyHelper (backed by the government), StepChange, National Debtline and Citizens Advice all help for free. You never need to pay for debt advice. Our guide to the debt snowball vs avalanche method explains how to choose which debt to clear first.
