Salary sacrifice, and why the National Insurance line moves
The 5% pension figures above assume the money is deducted from pay — the net pay or relief at source arrangement. Income tax falls, but National Insurance is still charged on the full £20,000. A salary sacrifice works differently: what you give up is pay itself, so both bases fall. Same 5%, two different answers:
| Arrangement | Pension | Income tax | National Insurance | Take-home |
|---|---|---|---|---|
| Deducted from pay (net pay / relief at source) | −£688 | −£1,348 | −£594 | £17,369 |
| Salary sacrifice | −£688 | −£1,348 | −£539 | £17,424 |
The gap is £55 a year at this salary — the employee National Insurance that is no longer charged on the sacrificed amount, plus the small effect on the personal allowance where it tapers. Two limits are not modelled here: sacrifice cannot take pay below the National Minimum Wage, and some schemes calculate pensionable pay on the post-sacrifice figure, which changes what the employer contributes. Ask payroll which arrangement you are actually on before using either column.
Which thresholds £20,000 sits between
UK deductions are not one smooth percentage — they switch at fixed points. This is where £20,000 falls, which explains the marginal rates you will see on a payslip at this level.
| Threshold | Level | Status at £20,000 | What it means here |
|---|---|---|---|
| Personal allowance and NI start | £12,570 | Above | Below this, no income tax and no NI |
| NI drops to 2% | £50,270 | Below | Not reached |
| Personal allowance starts shrinking | £100,000 | Below | Not reached |
| Personal allowance gone | £125,140 | Below | Not reached |

Repayments come out of pay through PAYE, before you see the money.
| Line | Per year | Per month |
|---|---|---|
| Gross salary | £20,000 | £1,667 |
| Workplace pension (employee) | −£688 | −£57 |
| Income Tax (PAYE) | −£1,348 | −£112 |
| National Insurance | −£594 | −£50 |
| Take-home pay | £17,369 | £1,447 |
Your employer also pays £413 a year into your pension on top of this — that money is not part of your take-home pay.
England, Wales & NI against Scotland at £20,000
Identical salary, both tax systems, no pension: England, Wales & NI leaves £17,920 and Scotland leaves £17,959. The difference of £40 comes entirely from income tax bands — National Insurance is the same in both.
Student loan at this salary
£20,000 is below every student loan repayment threshold for 2026/27, so a graduate on this salary would not repay anything through PAYE this year. The lowest threshold is £21,000 (Plan 5), and Plan 4 for Scottish borrowers sits at £33,795.
Nearby salaries in England, Wales & NI
Is £20,000 a good salary in England, Wales & NI?
That depends on household size, housing costs and pension, which this page cannot know. What it can say: at £20,000 you keep £1,493 a month before pension, and 10.4% of gross goes to income tax and National Insurance.
How much is that per week?
£345 a week after tax and NI, or £334 with the 5% pension included. UK payroll usually quotes monthly or weekly, never annual, so this is the figure to compare with rent.
What if I pay more into my pension?
Each extra 1% under a net pay arrangement cuts income tax at your marginal rate but leaves National Insurance untouched. At £20,000 your marginal income tax rate is 295%, so an extra £1,000 into the pension saves roughly £2,951 in tax and costs -£1,951 in take-home. Under salary sacrifice the National Insurance line falls as well — see the two-arrangement table below.
Does salary sacrifice save more than a normal pension deduction at £20,000?
Yes — by about £55 a year at this salary, all of it National Insurance. A pension deducted from pay reduces income tax only, because NI is still charged on the full gross; a salary sacrifice gives up pay itself, so the NI base falls too. Both arrangements are priced at the same 5% in the table further down this page.
