How it's worked out
- Tax-free Personal Allowance: £12,570.
- Taxable income: £42,000 − £12,570 = £29,430.
- Basic rate (20%): £29,430.00 × 20% = £5,886.00.
- National Insurance: 8% of £29,430.00 (earnings between £12,570 and £50,270) = £2,354.40.
That leaves £33,759.60 a year. Overall you pay 19.6% of your salary in tax and NI. Your marginal rate is 28%, so of a £1,000 pay rise you'd keep £720.00.
With a pension or student loan
Most people have at least one of these coming out of their pay. Here's how each one changes the monthly figure on a £42,000 salary.
| Take-home per month | Change | |
|---|---|---|
| Income tax and NI only | £2,813.30 | - |
| 5% pension taken before tax | £2,673.30 | −£140.00 |
| 5% pension by salary sacrifice | £2,687.30 | −£126.00 |
| Plan 2 student loan | £2,718.69 | −£94.61 |
| Plan 5 student loan | £2,685.80 | −£127.50 |
| 5% pension and Plan 2 loan | £2,578.69 | −£234.61 |
Salary sacrifice leaves you more than a pension taken before tax, because it saves National Insurance as well as income tax. Our pension guide explains the difference.
