Net to Gross Salary Calculator UK 2026/27
Enter your desired take-home pay — find out what gross salary you need
How to use this calculator
Enter the amount you want to take home — annually or monthly — and this calculator works backwards to find the gross salary you would need to earn to achieve that take-home pay in 2026/27. This is useful when negotiating a salary, setting a day rate, or planning finances.
Frequently asked questions
To take home £2,500/month (£30,000/year) in 2026/27 with no student loan or pension, you need a gross salary of approximately £36,800. The exact figure depends on your tax code, pension contributions, and student loan.
Gross salary is your total pay before any deductions. Net salary (take-home pay) is what you receive after income tax, National Insurance, pension contributions, and student loan repayments are deducted by your employer via PAYE.
Pension contributions are deducted before tax (for most workplace pensions), which reduces your taxable income. This means a higher pension contribution lowers the gross salary needed to achieve your desired take-home pay.

How the calculation works
This calculator uses a binary search algorithm to find the exact gross salary that results in your desired net pay:
- Start: Set a range of possible gross salaries (£0 to £500,000)
- Midpoint test: Calculate take-home for the midpoint salary using 2026/27 HMRC rates
- Narrow range: If take-home is too low, raise the lower bound; if too high, lower the upper bound
- Repeat: After 50 iterations the result converges to within pennies of the correct gross salary
- Deductions: Income tax, NI, pension contributions, and student loan are all accounted for

How much gross pay you need for different take-home pay levels
The table works backwards from the take-home pay you want to the gross salary you would need to be offered, using 2026/27 rates for England, Wales and Northern Ireland (Income Tax at 20/40/45%, employee National Insurance at 8% and 2%, standard code 1257L, no pension). The last column adds a Plan 2 student loan, which takes a further 9% of earnings above £29,385.
| Take-home pay wanted | Gross salary needed | Tax and NI taken | Gross needed with a Plan 2 loan |
|---|---|---|---|
| £18,000 (£1,500/mo) | £20,112 | £2,112 | £20,112 |
| £20,000 (£1,667/mo) | £22,889 | £2,889 | £22,889 |
| £24,000 (£2,000/mo) | £28,445 | £4,445 | £28,445 |
| £30,000 (£2,500/mo) | £36,778 | £6,778 | £37,835 |
| £36,000 (£3,000/mo) | £45,112 | £9,112 | £47,358 |
| £40,000 (£3,333/mo) | £50,763 | £10,763 | £54,690 |
| £50,000 (£4,167/mo) | £68,004 | £18,004 | £75,098 |
| £60,000 (£5,000/mo) | £85,246 | £25,246 | £95,506 |
| £80,000 (£6,667/mo) | £128,705 | £48,705 | £149,020 |
The gap between gross and net grows faster than the salary does because each extra pound is taxed at a higher marginal rate. In the basic-rate band you lose 28p of every extra pound (20% Income Tax plus 8% National Insurance), which is why £30,000 take-home needs about £36,778, only £6,778 more. Above £50,270 you lose 42p of each extra pound (40% plus 2% NI), so each additional £1,000 of take-home needs roughly £1,720 of extra gross pay. Between £100,000 and £125,140 the Personal Allowance is withdrawn and the effective marginal rate reaches about 62%.
When to use a net-to-gross calculation
Work backwards when you have a number you need rather than a number you are offered. Common cases include checking whether a job offer covers your monthly outgoings, deciding what to ask for in a salary negotiation, working out the pay rise you would need to cover a rent increase, and setting a minimum salary when changing careers. Use the monthly toggle if your budget is monthly, and remember that the result is a before-tax figure: a recruiter's advertised salary is always the gross number.
Pension, student loan and other deductions
Most workplace pension contributions reduce your taxable pay, so a higher pension percentage changes the gross salary needed for the same take-home. With a salary sacrifice scheme, the contribution also reduces National Insurance, which makes the cost to your pay packet smaller than the pension saving. A student loan is deducted on top of tax and NI, which is why the loan column is higher than the plain figure at every level above the repayment threshold. Other deductions such as union fees, share-save schemes and cycle-to-work payments are not included, so allow for them separately.
What this calculator does not cover
The results assume you live in England, Wales or Northern Ireland and use the standard tax code. Scottish taxpayers pay different Income Tax rates and bands, so use our Scotland take-home pay calculator instead. Self-employed people pay Class 4 National Insurance and file a tax return, so their position differs again. Bonuses, benefits in kind, company cars and a different tax code all change the result, and the tool gives an estimate to guide a decision, not a payroll calculation.
