The salary behind £4,000 a month
£4,000 a month is £48,000 a year, or £923 a week. Working back from that figure, the table shows the gross salary that delivers it under the most common deduction patterns.

How the working goes
Take-home pay cannot be turned back into a salary with a single percentage, because the deductions are layered: nothing on the first £12,570, then 20% income tax and 8% National Insurance up to £50,270, then 40% and 2%, with the personal allowance withdrawn between £100,000 and £125,140. The calculator behind this page finds the salary by searching for the gross figure whose take-home equals £48,000 exactly, and then repeats the search with each deduction added.
On the standard pattern, deductions take £16,556 of the £64,556 salary, 25.6% of it. Because the salary is above £50,270, each extra pound of take-home you want costs about £1.72 of gross pay at the margin, since 40% tax and 2% National Insurance come off first. The net to gross calculator runs the search for any target and any combination of deductions.
What the salary works out at

| Take-home an hour, 37.5 hour week | £24.62 |
Job adverts quote the gross figure, so £64,556 is the number to look for, or £33.11 an hour for a full-time hourly role. The hourly rate ladder shows every hourly rate as a yearly figure, and the salary after tax pages work in the other direction.
Why the other patterns need more
A student loan takes 9% of pay above the plan threshold before the money reaches you, so the salary has to be high enough to cover the repayment as well as the tax on it: £6,460 more on Plan 2. A 5% pension contribution needs £3,521 more in salary, less than the £3,404 contribution itself, because the contribution reduces the pay that is taxed. In Scotland the salary needed is £3,288 higher, because Scottish income tax takes more at this level. The take-home pay calculator confirms the monthly figure for any salary and pattern.
