| Before | After | Difference | |
|---|---|---|---|
| Salary | £30,000 | £31,500 | £1,500 |
| Take-home per year | £25,120 | £26,200 | £1,080 |
| Take-home per month | £2,093 | £2,183 | £90 |
| Take-home per week | £483.07 | £503.84 | £20.77 |
You keep about 72% of your pay rise after income tax and National Insurance (2026/27 rates, no pension or student loan).
How much of a pay rise do you keep?
A pay rise is taxed like the rest of your pay. For most employees in England, Wales and Northern Ireland, extra earnings between £12,570 and £50,270 lose 28p in every £1 (20p income tax plus 8p National Insurance). Above £50,270 you lose 42p (40p tax plus 2p NI).
That means a 5% rise on £30,000 (£1,500 extra a year) gives you about £1,080 more take-home pay: £90 a month. If you also repay a student loan or pay into a pension, you keep a little less.
Watch out for the tax thresholds
- £50,270: you start paying 40% on the next slice of income.
- £100,000 to £125,140: you lose Personal Allowance, so each extra £1 is effectively taxed at 60% before National Insurance. A pay rise here can leave you with little extra take-home, and pension contributions can help.
Typical pay rise sizes

| 3% | £30,900 | £54 |
| 5% | £31,500 | £90 |
| 7.5% | £32,250 | £135 |
| 10% | £33,000 | £180 |

Frequently asked questions
How much is a 5% pay rise?
On a £30,000 salary, a 5% rise adds £1,500 a year before tax, making £31,500. You take home around £1,080 more a year after tax and National Insurance.
Is a pay rise taxed more?
No. The rise is taxed at your normal marginal rate. It can look worse if it pushes you into a higher tax band or over a threshold, but you never end up with less take-home pay overall.
How do I calculate a percentage pay rise?
Multiply your salary by the percentage divided by 100, then add it to your salary. For a 4% rise on £25,000: £25,000 × 0.04 = £1,000, so the new salary is £26,000.
What is a good pay rise?
It depends on inflation, your sector and your performance. A rise that matches or beats inflation protects your spending power. Ask your employer how pay reviews work.
