UK Gross to Net Salary Calculator
What is gross salary vs net salary in the UK?
Gross salary is your total pay before deductions. Net salary (take-home pay) is what lands in your bank after deductions under PAYE.
- Income Tax
- National Insurance contributions
- Pension contributions (if applicable)
- Student loan repayments (if applicable)
This UK take-home pay calculator helps you estimate that difference quickly.
How to use this UK take-home pay calculator
1) Enter your gross annual salary
Use your contracted annual salary before deductions.
2) Add any annual bonus
If you receive regular bonus pay, include it so your estimated net pay is closer to reality.
3) Set pension salary sacrifice
If your workplace pension uses salary sacrifice, entering a percentage can reduce both Income Tax and National Insurance in this model.
4) Confirm tax code and region
Most people use 1257L, but custom tax codes can materially affect net income. Scottish taxpayers should choose Scotland for Scottish rates.
5) Select student loan plan
Different plans have different thresholds and repayment rates. Choosing the right one improves estimate quality.
What this calculator includes

What can make your real payslip different?
Your actual monthly net pay can vary versus any online UK salary calculator. Common reasons include:
- Non-salary-sacrifice pension arrangements (relief-at-source or net pay differences)
- Benefits in kind and tax adjustments
- One-off payroll adjustments, backpay, or irregular bonuses
- Changing tax codes during the tax year
- Payroll frequency effects (weekly/fortnightly/four-weekly/monthly)
Example: quick gross to net check
If someone earns £45,000 with 5% salary sacrifice pension and no student loan, their estimated annual net pay is usually much lower than gross, because the main deductions still add up significantly. This is why checking monthly take-home pay before accepting a job offer is so useful.
Why use a gross to net salary calculator before changing jobs?
- Compare job offers more accurately
- Estimate real monthly affordability for rent/mortgage
- Plan pension contributions with confidence
- Avoid overestimating post-tax income
