Example
Pay rise from GBP 45,000 to GBP 50,000
A worked example showing how a mid-range raise changes annual and monthly take-home pay.
Scenario
A move from £45,000 to £50,000 looks like a significant step. In net terms it produces the same £300/month gain as a raise from £30k to £35k or £40k to £45k — because all three raises sit entirely inside the basic-rate band. What makes this one different is what happens next: at £50,000 you are only £270 below the higher-rate threshold.
Take-home pay at £45,000
The personal allowance is £12,570. Taxable income is £45,000 minus £12,570 = £32,430.
| Deduction | Calculation | Annual amount | |---|---|---| | Income tax | £32,430 × 20% | £6,486 | | Employee NI | £32,430 × 8% | £2,594 | | Total deductions | | £9,080 | | Annual take-home | £45,000 − £9,080 | £35,920 | | Monthly take-home | £35,920 ÷ 12 | £2,993 |
Take-home pay at £50,000
Taxable income rises to £50,000 minus £12,570 = £37,430. The higher-rate threshold is £50,270 — your new salary of £50,000 is still £270 below it, so the entire income remains in the basic-rate band.
| Deduction | Calculation | Annual amount | |---|---|---| | Income tax | £37,430 × 20% | £7,486 | | Employee NI | £37,430 × 8% | £2,994 | | Total deductions | | £10,480 | | Annual take-home | £50,000 − £10,480 | £39,520 | | Monthly take-home | £39,520 ÷ 12 | £3,293 |
The gain from the raise
| | Before (£45k) | After (£50k) | Increase | |---|---|---|---| | Annual take-home | £35,920 | £39,520 | £3,600 | | Monthly take-home | £2,993 | £3,293 | £300 |
The £5,000 gross raise delivers £3,600 net per year, or £300 per month. You still keep 72p of every extra pound — the 20% + 8% basic-rate stack applies to the entire £5,000.
The higher-rate threshold warning
At £50,000 you are just £270 below the higher-rate threshold of £50,270. That is a narrow margin, with two immediate consequences:
1. Any future pay rise — even a modest £500 cost-of-living increase — will push the top portion of your salary into the higher-rate band, where income tax rises from 20% to 40% and NI drops from 8% to 2%. The combined marginal rate becomes 42% rather than 28%, so you keep only 58p per extra pound.
2. Any bonus will start crossing the threshold immediately. A £1,000 bonus, for example, would see £270 taxed at 28% and £730 taxed at 42%, producing a net bonus of around £756 rather than the £720 you might expect if the whole amount stayed at basic rate.
This page's raise itself clears cleanly — but it positions you right at the edge of the basic-rate band.
With Plan 2 student loan
Plan 2 repayments apply at 9% on earnings above £27,295.
| | Before (£45k) | After (£50k) | Difference | |---|---|---|---| | Plan 2 repayment | (£45,000 − £27,295) × 9% = £1,594 | (£50,000 − £27,295) × 9% = £2,043 | £450 | | Annual take-home after Plan 2 | £34,326 | £37,477 | £3,150 | | Monthly take-home | £2,861 | £3,123 | £263 |
With Plan 2 active, you keep 63% of the gross raise rather than 72%.
