How the reverse calculation works

Most salary tools go forwards: enter a gross salary, see the take-home. This one runs the other way. You tell it the monthly net pay your budget requires, and it searches through gross salaries — applying the 2026/27 Income Tax bands and National Insurance at each candidate — until the resulting take-home matches your target. The maths is the same engine as our forward tools, simply iterated.

This is genuinely useful when you are planning around the cost of living. Rather than guessing whether a £35,000 role covers your outgoings, you can state “I need £2,300 a month clear” and read off the salary that delivers it.

Mind the gap. Above the £12,570 thresholds every extra pound of gross pay loses 20% to Income Tax and 8% to National Insurance, so the salary you need is meaningfully higher than the net you want. Cross higher-rate territory and the gap widens.

Worked example: £2,500 a month net

Say you need £2,500 take-home each month — that is £30,000 a year clear. The tool searches upward and finds that a gross salary of roughly £40,200 produces it:

  • Gross: about £40,200.
  • Income Tax: about £5,526.
  • National Insurance: about £2,210.
  • Take-home: about £30,000 a year, or £2,500 a month.

For a precise breakdown of that gross figure, drop it into the income tax calculator.

Using it for budgeting

Pair the result with your essential outgoings — rent or mortgage, bills, food and travel — to judge whether a role is viable. If the required salary looks out of reach, a pension contribution or salary-sacrifice arrangement can change the picture by reducing taxable pay. This tool is a planning aid, not advice.
