Why Work Backwards From Take-Home Pay?
Job adverts and salary negotiations are almost always framed in gross salary, but what actually matters to your budget is what lands in your bank account. This calculator inverts the usual maths — tell it the monthly or annual take-home you need, and it works out the gross salary to ask for, accounting for Income Tax, National Insurance, your region, pension contributions and any student loan.
How the Calculation Works
Because Income Tax and National Insurance are banded (not a single flat rate), there's no simple formula to reverse — this tool searches for the exact gross salary whose take-home pay matches your target, using the same deterministic bands as the main take-home pay calculator.
Useful for salary negotiations, evaluating a job offer against your current take-home, or setting a minimum acceptable rate when freelancing or contracting.

The figure above is an estimate of what you're entitled to or what it costs you — deciding what to actually do with it (invest, overpay debt, top up a pension) is a bigger decision worth getting right.
- Received a redundancy payout: understand tax-free thresholds and how to make a lump sum work for you long-term.
- Planning parental leave: budget around the drop from full pay to statutory rate, and check what protections apply.
- Deciding whether to overpay a student loan: for many people investing the surplus outperforms early repayment — but it depends on your plan type and income trajectory.
- Reviewing pension contributions: small percentage changes compound significantly over a career.
