Knowing how to calculate take-home pay helps you judge a job offer, plan a budget and spot mistakes on your payslip. Your take-home pay is the money that actually reaches your bank account after tax, National Insurance and any other deductions have come out of your gross salary. For most people in the UK it is a lot lower than the headline figure, and the gap depends on a handful of numbers you can check yourself.
This guide explains what take-home pay is, what comes out of it, how to work it out step by step with a worked example and what can change the result.
What is take-home pay?
Take-home pay, also called net pay, is what you receive after deductions. Gross pay is the amount in your contract before anything is taken off. The difference between the two is made up of Income Tax, National Insurance and, depending on your situation, pension contributions, student loan repayments and other deductions.
When an employer says a job pays £35,000, that is gross pay. What you can spend each month is the net figure on your payslip, and a take home calculator is the fastest way to see it for your own salary and tax code.
What comes out of your gross pay
- Income Tax: you pay nothing on the first £12,570 of income, the standard personal allowance. In England, Wales and Northern Ireland the basic rate of 20% applies to income up to £50,270, then 40% above that, and 45% on income above £125,140. Scotland has its own bands.
- National Insurance: employees pay 8% on earnings between £12,570 and £50,270 a year, and 2% on anything above.
- Workplace pension: under automatic enrolment, employees usually pay at least 5% of qualifying earnings, although the exact amount depends on the scheme.
- Student loan: repayments start once your income passes the threshold for your plan and are taken as a percentage of the income above it.
- Other deductions: examples include salary sacrifice benefits, union fees and payroll giving.
How to calculate take-home pay, step by step
- Start with your gross annual salary. Use the figure in your contract, before any deductions.
- Subtract your tax-free allowance. For most people this is £12,570. Your tax code on a payslip, usually 1257L, shows what has been applied.
- Apply the Income Tax rates. Multiply the income above the allowance by 20% up to the basic rate limit, then 40% and 45% for any income above the higher thresholds.
- Work out National Insurance. Multiply the earnings between £12,570 and £50,270 by 8% and anything above by 2%.
- Deduct pension and other items. Take off your pension contribution, student loan repayment and any other deductions that apply to you.
- Divide by 12 or 52. This turns the annual result into monthly or weekly take-home pay.
Here is an example for someone in England on £35,000, with no pension or student loan. Income Tax is 20% of the £22,430 above the allowance, which is £4,486. National Insurance is 8% of the same £22,430, which is £1,794. Together that is about £6,280, so annual take-home pay is roughly £28,720, or about £2,393 a month. Pension contributions and a student loan would reduce that further, so the quickest way to check the exact figure for your salary and deductions is an online calculator that does all of these steps for you.
What changes your take-home pay
- Your tax code: a wrong code can mean you pay too much or too little tax, so check it on your payslip.
- Where you live: Scottish taxpayers pay Income Tax at different rates and bands from the rest of the UK.
- Pension contributions: contributions made before tax reduce your taxable pay, so the cost to your take-home pay is lower than the contribution itself.
- Student loan plan: the plan you are on sets the threshold and the percentage taken.
- Bonuses and overtime: extra pay is taxed at your marginal rate, which can make a bonus look smaller than expected.
- Benefits in kind: a company car or private medical insurance can change your tax code and reduce your pay.
Gross pay vs net pay: why it matters
Comparing job offers by gross salary alone can be misleading. A higher salary with a large student loan repayment and a generous pension contribution can leave you with less cash each month than a lower salary with fewer deductions. Always compare the monthly take-home figure after your own deductions, and check whether the offer includes employer pension contributions on top.
Common mistakes to avoid
- Using gross pay for budgeting. Plan with the net amount that reaches your account.
- Forgetting the part-year effect. If you start a job part-way through the tax year, your payslips and your annual total will not match a simple 12-month calculation.
- Ignoring your tax code. An emergency or wrong code can take hundreds of pounds a year from your pay until it is corrected.
- Leaving out student loan or pension. Many online figures omit them, so check what is included.
Frequently asked questions
What is take-home pay?
It is the amount you receive after Income Tax, National Insurance and other deductions are taken from your gross salary. It is the figure on your payslip labelled net pay.
How do I work out take-home pay from gross?
Subtract the £12,570 personal allowance, apply the Income Tax rates to the rest and add up National Insurance. Then deduct any pension and student loan and divide by 12 for a monthly figure.
What is the difference between gross and net pay?
Gross pay is your salary before deductions and net pay is what remains after tax, National Insurance and any other deductions. Your payslip shows both figures.
How much is £30,000 after tax in the UK?
For someone in England with no pension or student loan, £30,000 leaves roughly £25,120 after Income Tax and National Insurance, or about £2,093 a month. Other deductions will reduce it.
Why is my take-home pay lower than I expected?
Common reasons are a pension contribution, a student loan repayment, an emergency tax code or a benefit in kind. Check your payslip against your tax code and contract.
