Convert gross UK salary into estimated net pay after PAYE, National Insurance, pension, and student loan deductions.
How gross to net is worked out
Gross pay is the headline figure in the contract. Net pay is what is left once PAYE Income Tax, employee National Insurance, any pension contribution and any student loan repayment have come off. Each one is worked out on a different base, which is why two people on the same gross salary can take home different amounts: the tax code sets how much pay is tax-free, National Insurance has its own thresholds and ignores the code, and student loan repayments start above a threshold set by the plan.
Of £35,000.00 gross a year: Income Tax £4,486.00, National Insurance £1,794.40, Take-home £28,719.60.
Saving £120 a month — about 5% of this take-home — becomes £7,941.48 in five years at an example 4%: try the savings calculator.

Changing the rate or method can change taxable income, National Insurance and take-home pay.
Tax code and region
Scottish Income Tax, Welsh codes, emergency tax or a non-standard tax code can move the result.
Student loan plan
A different plan can change deductions because each plan uses its own threshold and repayment rate.

Extra pay and payroll timing can make a real payslip differ from the smooth annual estimate.

What the gross to net estimate assumes
The figures on this page are worked from gross to net, using the values below. Open the calculator if your example salary differs.
Example salary£35,000 annual gross
What would change this figure
This estimate is worked out on £35,000 annual gross. Change any of those and the take-home figure moves; pension method and student loan plan usually move it most. A payslip can differ from any calculator because payroll works pay period by pay period, so a tax-code change, a bonus, arrears or a refund can land in one month and not the next. See how each deduction is worked out.
It starts from the question on this page, shows the useful salary assumptions, and opens PayBreakdown's calculator so gross pay, take-home pay, tax, National Insurance, pension, student loan, region, and tax-code settings can be adjusted.
Can I change the assumptions?
Yes. Open the calculator from this page to change salary, hours, pension, student loan, tax year, region, tax code, bonus, and other pay settings.
