Why you keep less than 3% of your pay rise
A 3% pay rise of £990 sounds significant, but the effective marginal tax rate on this additional income is 0.28080808080808084% — meaning you only keep £712 of the £990 increase.
The marginal rate combines income tax (20% or 40% depending on your band) and employee NI (8% on earnings between £12,570 and £50,270, 2% above). A pay rise that pushes you into the higher rate band (above £50,270) will be taxed at 42% on the portion above that threshold.

Understanding your pay rise after tax
When you receive a 3% pay rise from £33,000 to £33,990, the £990 increase in gross pay does not translate directly into more take-home pay. Income Tax and National Insurance are deducted from the additional earnings at your marginal rate — the rate that applies to the top slice of your income.
For most employees earning between £12,570 and £50,270, the marginal rate is 28%: 20% income tax plus 8% employee NI. Above £50,270, NI drops to 2% but income tax rises to 40%, giving a marginal rate of 42%. If your pay rise takes you over the £50,270 threshold, the portion above it is taxed at 42% rather than 28%.
If you want to maximise the benefit of your pay rise, consider salary sacrifice into a pension — contributions made this way reduce your taxable pay, effectively giving you the full gross value of part of your rise tax-free. You can also use a pension calculator to model the long-term impact.
