Reverse Salary Calculator (2026/27)
Start from the take-home pay you want and work back to the salary you need. Covers England, Wales, Northern Ireland and Scotland, with pension and student loan deductions included.
The salary you need
An estimate for guidance only, not financial advice. Assumes a single PAYE salary taxed under the standard Personal Allowance for 2026/27. If your tax code is not the standard one, the gross needed will differ.
What salary do I need to take home a given amount?
The gross salary required for each common monthly take-home target in 2026/27, with Scotland alongside because the answer genuinely differs.

| £1,500/mo | £18,000 | £20,112 | £20,057 | −£55 |
| £2,000/mo | £24,000 | £28,445 | £28,390 | −£55 |

England, Wales and Northern Ireland against Scotland for 2026/27. No pension, student loan or other deductions assumed — each of those raises the gross needed.
Working the other direction instead — you know the salary and want the take-home? Use the main take-home pay calculator, or read the band-by-band breakdown for a specific salary.
What one pound of take-home actually costs
This is the part a forward calculator hides. Because Income Tax is marginal, the price of an extra pound in your pocket depends entirely on where you already are — and it rises in steps, not smoothly.
| Take-home | Gross salary | Where that lands | Gross cost of £1 more take-home |
|---|---|---|---|
| £2,000/mo | £28,445 | Basic rate band | £1.39 |
| £3,500/mo | £54,211 | Higher rate band | £1.72 |
| £6,000/mo | £109,059 | Personal Allowance taper | £2.63 |
In the basic-rate band you give up 20% Income Tax and 8% National Insurance, so about £1.39 of gross is needed for each £1 of take-home. Cross into the higher-rate band and that becomes £1.72.
The worst region is the Personal Allowance taper between £100,000 and £125,140, where the allowance is withdrawn by £1 for every £2 earned on top of the 40% rate. There, £2.63 of gross is needed for each extra pound of take-home — which is the same 60% effective marginal rate seen from the other side. A student loan pushes every one of these figures higher again.
Scotland: the crossover
Scottish taxpayers do not simply need a bigger salary for the same take-home — it depends where you are on the scale, and the direction reverses.
At a £2,000 monthly take-home a Scottish taxpayer needs £55 less gross than someone in the rest of the UK, because Scotland's starter and basic bands are more generous at lower incomes. By £3,000 a month the position has flipped and they need £841 more. At £5,000 a month the gap widens to £4,835.
That is the same crossover the Scottish Income Tax pages describe from the forward direction, where Scottish taxpayers begin paying more than the rest of the UK at around £33,500 of salary.
Why there is no simple net-to-gross formula
Going forwards is arithmetic. Going backwards is not, and it is worth being honest about why.
UK take-home pay is piecewise. Income Tax changes rate at its band boundaries, National Insurance changes rate at the primary threshold and again at the upper earnings limit, the Personal Allowance tapers away between £100,000 and £125,140, and a student loan starts at a threshold of its own. Those breakpoints do not line up with each other, so the relationship between gross and net is a chain of straight lines with different slopes rather than one line.
You can rearrange the formula within any single segment, but you have to know which segment the answer lands in before you can pick the right rearrangement — and that is the thing you are trying to find out. So this calculator does the honest version: it runs the real forward calculation repeatedly, narrowing the range until it finds the gross figure that produces your target take-home exactly. It never stores a rate of its own, which means it cannot drift out of date when the bands change each April.
Reverse salary calculator FAQ
What salary do I need to take home £3,000 a month?
About £45,112 a year in England, Wales or Northern Ireland for 2026/27, assuming no pension contributions or student loan. In Scotland you would need roughly £45,953 for the same take-home. Adding a pension contribution or a student loan raises the gross needed.
How do you work out gross salary from net pay?
There is no single formula, because UK take-home pay is piecewise: Income Tax bands, the National Insurance thresholds and the Personal Allowance taper all have different breakpoints that do not line up. This calculator inverts the real calculation by narrowing in on the gross figure that produces your target net, which is exact to the penny and stays correct when rates change.
Why does more take-home cost so much more gross?
Because each extra pound is taxed at your marginal rate, not your average one. Around £2,000 a month of take-home, one more pound of net pay costs about £1.39 of gross. In the higher-rate band that rises to £1.72, and inside the Personal Allowance taper it reaches £2.63 — because the allowance is being withdrawn at the same time as the 40% rate applies.
Do I need a bigger salary in Scotland for the same take-home?
Above roughly a £2,500 monthly take-home, yes. The crossover matters: at £2,000 a month a Scottish taxpayer actually needs slightly less gross, because Scotland's starter and basic bands are more generous at lower incomes. At £5,000 a month the position reverses sharply and a Scottish taxpayer needs about £4,835 more gross for the identical take-home.
Does this include pension and student loan deductions?
The headline figures assume neither. Both increase the gross salary you need, because they come out of the same pay: a student loan takes 9% of everything above your plan's threshold, and a pension contribution reduces take-home pound for pound even though it saves tax. Use the options in the calculator to include them.
Is take-home pay the same as net pay?
Yes, they mean the same thing — the amount that actually reaches your bank account after Income Tax, National Insurance and any other deductions your employer takes. Gross pay is the headline salary figure before any of that comes off.
