Estimate the gross UK salary needed for a target net take-home amount, then compare it with tax, NI, pension, and student loan assumptions.
Use this net-to-gross calculator when you know the monthly take-home pay you want and need an estimated gross UK salary to compare. It uses the shared PAYE engine with tax year, region, pension and student-loan assumptions, then links to the deeper required-salary tool for further checks.
Enter the take-home pay you need and this solves for the gross salary that produces it.
A gross salary of £36,778 leaves about £30,000 after Income Tax and National Insurance — £2,500 a month.
2026/27 rates, England, Wales and Northern Ireland, no student loan. Open the full calculator to change region, student loan or pension method.
Payslip showing different figures? The payslip checker works out what your pay and tax code should have produced and shows which assumption could explain the gap.
Planning estimate only. Pay-event outputs cannot confirm real payroll treatment, HMRC records, employer policy, employment terms, or payslip timing.

|---|---|

| Tax code | HMRC tax-code changes, K codes, BR/D codes, or emergency markers can change PAYE deductions. |

The figures on this page are worked from net to gross, using the values below. Open the calculator if your example salary differs.
The calculator tests gross annual salary amounts until it reaches the target monthly take-home estimate under the selected PAYE assumptions.
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 estimates the gross annual salary needed to reach a target monthly take-home amount after Income Tax, National Insurance, pension and student-loan assumptions.
Real payroll can differ because of tax code changes, pension method, student-loan records, benefits, bonuses, overtime, previous-period adjustments and payroll timing.
Yes. This page includes quick pension-rate and student-loan settings, and the related required-salary tool can be used for further scenario checks.
