Tell us the take-home pay you're aiming for and we'll work backwards to the gross salary that gets you there — useful for negotiating offers, setting a rate as a contractor, or working out what a job needs to pay.
There's no simple formula for "gross needed to net £X" — so this calculator searches for the exact answer instead of guessing at one.
Income Tax is banded, National Insurance has its own thresholds, and student loan repayments only kick in above a plan-specific figure — and above £100,000 your Personal Allowance itself starts shrinking, changing the shape of the curve again.
It tries a gross salary, calculates the resulting take-home exactly the way the main NetSlip calculator does, and narrows in until the take-home matches what you asked for, to the penny.
This is particularly useful when negotiating a job offer around a take-home number a landlord or lender expects, when setting a day rate as a contractor, or when you simply want to know what payrise would be needed to clear a certain amount every month after deductions.
Rates and thresholds are for the 2026/27 tax year (6 April 2026 – 5 April 2027). This calculator is provided for planning purposes and doesn't account for every individual circumstance — treat it as a strong estimate, not a guarantee.
