For each monthly amount: what it is a year, the take-home if it's your gross pay, and the salary you need if it's what you want to take home. 2026/27 rates for England, Wales and Northern Ireland.
"Take-home" treats the amount as your gross (before-tax) monthly pay. "Salary needed" treats it as the amount you want left after Income Tax and National Insurance, and gives the yearly salary that pays it. Both assume no pension or student loan; the UK salary calculator handles those.
