If you've ever looked at your payslip and wondered where a chunk of your salary went, a take home pay calculator is the fastest way to get a clear answer. It takes the number on your employment contract — your gross salary — and shows you exactly what's left after Income Tax, National Insurance, pension contributions and student loan repayments. No jargon, no spreadsheets — just the figure that actually matters: what lands in your bank account.
A take home pay calculator converts your gross (before-tax) salary into your net (after-tax) take-home pay. Enter your annual salary, tax code, and deduction details, and the tool instantly shows what you'll actually receive after Income Tax, National Insurance, pension, and student loan deductions.
Your Salary Details
Take Home Pay Calculator: A Plain-English Definition
A take home pay calculator is a free online tool that does one specific job: it works out how much of your salary you actually keep. You enter your gross annual salary — the big number on your contract — along with a few details about your situation (tax code, pension, student loan), and the calculator applies all the relevant UK tax rules to show your net (take-home) pay.
The "take-home" part of the name is literal — it's the money you take home. Everything else goes to HMRC (through Income Tax and National Insurance), your pension provider, or the Student Loans Company.
Gross Pay, Net Pay and Deductions
Three terms you'll see on every payslip and every salary calculator:
- Gross pay — your total salary before any deductions. This is the headline number in job adverts and employment contracts.
- Deductions — the amounts subtracted from your gross pay. The main ones are Income Tax, National Insurance, pension contributions, and student loan repayments.
- Net pay (take-home pay) — what's left after all deductions. This is the figure that appears in your bank account on payday.
The relationship is simple: Gross Pay − Deductions = Net Pay. A take home pay calculator automates this arithmetic using the current tax year's official rates and thresholds.
What Each Deduction Actually Is
Income Tax
Income Tax is the UK government's main tax on earnings. It's collected through a system called PAYE (Pay As You Earn) — your employer calculates the amount and sends it directly to HMRC before you see your pay. The amount depends on how much you earn and which tax band your income falls into (20%, 40%, or 45% for the rest of the UK; six bands in Scotland ranging from 19% to 48%).
National Insurance
National Insurance is a separate deduction from Income Tax. It funds state benefits (including the State Pension, NHS, and statutory sick pay). Employees pay 8% on earnings between £12,570 and £50,270 per year, and 2% above that. It appears as a separate line on your payslip.
Pension Contributions
If you're enrolled in a workplace pension (which is automatic for most UK employees), a percentage of your pay is deducted and invested for your retirement. The minimum auto-enrolment contribution is 5% of qualifying earnings (with your employer adding at least 3%). This reduces your take-home pay now but builds your retirement savings.
Student Loan Repayments
If you have a student loan, repayments are deducted from your salary once you earn above a certain threshold. The rate is 9% of income above the threshold for Plan 1, 2, 4, and 5, and 6% for Postgraduate loans. The thresholds vary by plan — for example, £27,295 for Plan 2 in 2026/27.
Frequently Asked Questions
A take home pay calculator is a free online tool that shows you how much of your gross salary you actually receive after deductions. You enter your annual salary, tax code, pension rate, and student loan plan, and the calculator works out your Income Tax, National Insurance, and other deductions to show your net (take-home) pay.
Your take home pay is the amount of money that actually arrives in your bank account after all payroll deductions — Income Tax, National Insurance, pension contributions, and student loan repayments — have been subtracted from your gross salary. It's also called net pay.
Gross pay is your total salary before any deductions. It's the headline figure on your employment contract. For example, if your contract says £35,000 per year, that's your gross pay. Your take-home (net) pay will be lower after Income Tax, National Insurance, and other deductions.
Net pay is the amount you receive after all deductions have been taken from your gross salary. It's the same as take-home pay. The word 'net' means the clean or final amount — what's left after everything has been subtracted.
PAYE stands for Pay As You Earn. It's the system HMRC uses to collect Income Tax and National Insurance directly from your salary before you receive it. Your employer calculates and deducts the correct amounts each pay period and sends them to HMRC on your behalf.
The Personal Allowance is the amount of income you can earn each year without paying any Income Tax. For the 2026/27 tax year, the standard Personal Allowance is £12,570. If you earn over £100,000, your allowance is gradually reduced by £1 for every £2 above the threshold.
A tax code is a combination of numbers and letters that tells your employer how much tax-free income you're entitled to. The standard code 1257L means you have a Personal Allowance of £12,570. Different codes adjust this allowance — for example, if HMRC is collecting unpaid tax from a previous year.
The amount depends on your gross salary, tax code, pension contributions, and student loan plan. Use the take home pay calculator on this page to enter your details and see an instant breakdown of your paycheck after all deductions. For a £30,000 salary on a standard tax code, expect roughly £2,093 per month.
