How to budget: a beginner's guide

By The Income Tracker · Updated 16 September 2026 · 6 min read

The short answer

A budget is your income minus your spending, planned before the month starts and checked after it ends. Start with one month of real bank transactions, not estimates. Sort them into about ten categories and you will know your essentials, your flexible spending and your surplus (or deficit) inside twenty minutes. Then decide three things: what to cut, what to save, and when you will look again.

Step 1: know what actually lands

Use take-home pay, after tax, National Insurance, pension and student loan. Add benefits and any regular extra income. If you are paid weekly or four-weekly, convert to a monthly average (weekly times 52, divided by 12) and remember some months will have an extra payday.

Step 2: get one month of real transactions

Guessing is where budgets die. Download last month's transactions from your bank as a CSV. Every UK bank can do it and this site has a guide for each. Import the file into The Income Tracker and every line is on screen with its date and amount. Only got a PDF? Copy the rows and paste them in.

Step 3: ten categories, no more

Housing, Bills, Groceries, Transport, Debt, Subscriptions, Eating out, Shopping, Health, Savings. Drag each transaction into one. Thirty categories look thorough and get abandoned by week three; ten is enough to see where the money goes.

Step 4: read your three numbers

NumberHow to get itWhat it tells you
EssentialsHousing + Bills + Groceries + Transport + minimum debt paymentsWhat the month costs before any choices
Flexible spendingEverything else except savingsWhere cuts are possible
SurplusIncome minus everythingWhat you can save, or the size of the problem

Step 5: pick a method you will keep

None is better in general. The best method is the one you are still doing in March.

MethodIn one lineSuits
50/30/20Half on needs, 30% on wants, 20% to savings and debtA simple target with room to move
Zero-basedEvery pound gets a job before the month startsPeople who like control
Pay yourself firstMove savings on payday, spend what remainsPeople who hate tracking

Step 6: the ten-minute monthly check

On the first weekend of the month, import the new statement, categorise what is new (the app remembers the rest), and compare the three numbers with last month. Adjust one thing. That habit, repeated, is the entire skill.

If the surplus is negative

First, pay the priority bills: rent or mortgage, council tax, energy, and anything with a court or licence behind it. Then cut flexible spending and look at subscriptions. If it still does not balance, talk to a free advice service such as StepChange, Citizens Advice or National Debtline before it becomes arrears. A negative number on a budget is information, not a verdict.

Frequently asked questions

How do I start a budget with no experience?
Get one month of real bank transactions, sort them into ten categories, and read three numbers: essentials, flexible spending and surplus. That takes about twenty minutes and tells you exactly where you stand.
What is the easiest budgeting method?
Pay yourself first is the least effort: move savings on payday and spend the rest. 50/30/20 gives a target to aim for. Zero-based is the most control and the most work.
Do I need an app to budget?
No, but it saves typing. A free tool that reads your bank CSV, such as The Income Tracker, does the sorting and totals so the monthly check takes minutes.
How often should I check my budget?
Once a month, on a set day, is enough for most people. Weekly checks help in the first two months while the habit forms.
