How UK Take-Home Pay Is Worked Out [2026/27]

The building blocks of your payslip

Every UK payslip starts with your gross pay — your salary before anything is taken off — and ends with your net pay, the amount that actually lands in your bank account. In between sit four deductions, applied in a specific order that most people never see. Understanding that order is the key to understanding your pay, because a pound moved from one stage to another can be worth very different amounts.

The four deductions are: pension contributions, income tax, National Insurance, and student loan repayments. Depending on your pension scheme, contributions are usually taken off first, reducing the figure that tax and NI are then calculated on. That single fact is why a workplace pension is often described as the most tax-efficient thing an ordinary employee can do.

Income tax: the personal allowance and the bands

Income tax in England, Wales and Northern Ireland works in slices. You do not pay one rate on your whole salary — you pay each rate only on the portion of income that falls inside its band. For 2026/27 the bands are:

• Personal allowance — £0 to £12,570: taxed at 0%. Everyone with income under £100,000 gets this tax-free slice.
• Basic rate — £12,570 to £50,270: taxed at 20%.
• Higher rate — £50,270 to £125,140: taxed at 40%.
• Additional rate — above £125,140: taxed at 45%.

A common myth is that getting a pay rise into the higher-rate band means you “take home less”. That is not how slices work: only the pounds above £50,270 are taxed at 40%, so every extra pound still leaves you better off — just not by as much. The one genuine trap is the £100,000 threshold, where your personal allowance is withdrawn by £1 for every £2 earned. Between £100,000 and £125,140 that withdrawal creates an effective 60% marginal rate, one of the quirks of the UK system worth planning around.

If you live in Scotland, income tax is devolved and uses six bands rather than three, with a starter rate below 20% and intermediate and advanced rates in between — so a Scottish taxpayer on the same salary takes home a slightly different amount. Our Scottish take-home pay calculator handles those bands.

National Insurance

National Insurance (NI) is a second tax on earnings, but it uses a flatter structure. For employees in 2026/27, you pay 8% on earnings between £12,570 and £50,270, and 2% on everything above £50,270. Unlike income tax, NI is normally calculated on each pay period rather than annualised, which is why a large one-off bonus can be hit slightly differently from regular salary.

The important thing to notice is what happens at the top: above £50,270, income tax jumps to 40% but NI drops to 2%. So the combined marginal rate on higher-rate income is 42%, not 48% — a detail that matters when you're weighing up a pay rise or an extra pension contribution.

Pension contributions and salary sacrifice

A workplace pension contribution is deducted before income tax, so a basic-rate taxpayer effectively gets 20% of it back, and a higher-rate taxpayer 40%. Put £100 into your pension and it costs a higher-rate taxpayer just £60 of take-home pay.

Salary sacrifice goes one step further. Instead of paying into a pension out of taxed salary, you agree to a lower gross salary and your employer pays the difference straight into your pension. Because your gross salary is now lower, you save both income tax and National Insurance on the sacrificed amount — and many employers pass on their own NI saving too. It's the single most efficient way to boost pension savings, and it can also pull your taxable income back below the £100,000 taper or the higher-rate threshold.

Student loan repayments

If you studied at university, student loan repayments come out of your pay once you earn above a plan-specific threshold. You repay 9% of income above the threshold (6% for a postgraduate loan), and the threshold depends on which plan you're on:

• Plan 1 — older loans, with the lowest threshold.
• Plan 2 — most English and Welsh graduates who started from 2012.
• Plan 4 — Scottish borrowers.
• Plan 5 — students who started courses from 2023 onwards.
• Postgraduate loan — repaid at 6%, on top of any undergraduate plan.

Student loan repayments are not really a “tax” — they clear a debt — but they reduce your take-home pay all the same, so any honest calculation has to include them. If you're on two plans at once (an undergraduate and a postgraduate loan), both apply.

A worked example

Take a £50,000 salary in 2026/27, standard tax code, no student loan and no pension contribution:

Now add a 5% pension contribution (£2,500). That £2,500 comes off before tax, so you save £500 in tax on it — the contribution reduces your take-home pay by only about £2,000, while £2,500 lands in your pension. This is the leverage that makes pensions so powerful, and it's exactly the kind of trade-off worth testing before you set your contribution rate.

Because everyone's tax code, pension and student-loan situation is different, the only way to get your number is to run it. The take-home pay calculator applies the finalised 2026/27 rates and shows the full breakdown; if you want to compare two offers side by side, the compare-two-salaries tool does it in one view.

Why your real payslip might differ

Online estimates assume the standard tax code (1257L) and no complications. Your actual pay can differ because of a non-standard tax code, benefits in kind (like a company car or private medical cover), a second job that uses up your allowance, workplace benefits, or simply living in Scotland. Your tax code and payslip are always the authoritative source — check them against gov.uk if a figure looks wrong, and contact HMRC if your code seems incorrect.
