What gross salary do I need for a specific net income?

It depends on your pension contributions and student loan plan as well as the target itself, since both reduce or reshape the calculation, but broadly the calculator works backwards through the 2026/27 income tax bands (20%/40%/60%/45%) and employee National Insurance (8%/2%) to solve for the required gross figure.

How do I reverse-calculate my required salary from a take-home target?

Enter the net income you want — for example, enough to take home £3,000 a month — and the calculator works backwards through 2026/27 income tax and National Insurance to find the gross annual salary that would produce it, rather than you having to guess and check with a standard forward calculator.

Why does the salary I need for the same take-home keep rising each year?

Because the personal allowance (£12,570) and the higher-rate threshold (£50,270) have been frozen since 2021 and are set to remain frozen until 2030/31 following the Autumn Budget, a growing share of any salary is taxed at higher rates each year even without inflation-adjusted increases to those thresholds — commonly known as fiscal drag.

Does this work for a monthly take-home target as well as annual?

Yes — enter either a monthly or annual net income target, and the calculator annualises it consistently before solving backwards for the required gross salary.

The gross salary you actually need for a given take-home target

Working out the gross salary you'd need to hit a specific net income target — a monthly figure to cover your outgoings, or matching a previous take-home — means running the 2026/27 income tax and National Insurance calculation in reverse. Because the personal allowance and higher-rate threshold have been frozen since 2021 and, following the Autumn Budget, are set to stay frozen until 2030/31, the gross salary needed to hit the same net target tends to creep up each year even without a real pay rise.

How to use this calculator
