How Take-Home Pay Is Calculated in the UK (2026/27) — With Examples

Understanding your payslip is the first step to feeling in control of your money. Yet millions of UK workers glance at their monthly figure without ever knowing exactly how HMRC arrived at it. This guide walks through the whole calculation — the same one used by our take-home pay calculator — using the 2026/27 rates.

The building blocks

Your take-home pay is your gross salary minus four deductions: income tax, employee National Insurance, any pension contribution you make, and any student loan repayment. Everything else (salary sacrifice, benefits in kind) is a variation on those four themes.

Step 1: Work out taxable income

For most employees, taxable income equals your gross salary minus any salary-sacrifice pension contributions. Salary sacrifice literally reduces the pay used to calculate both income tax and National Insurance — which is why increasing pension contributions can lower your tax bill twice over. Our salary sacrifice calculator shows the effect side by side with a standard contribution.

If your pension uses "relief at source" instead (common for personal pensions and NEST), your gross salary is unchanged and the tax relief is added back into the pension pot. The end result for basic-rate taxpayers is similar, but the mechanics are different.

Step 2: Apply the personal allowance

Every UK taxpayer gets a personal allowance — £12,570 for 2026/27 — of income taxed at 0%. Above £100,000 the allowance tapers by £1 for every £2 of extra income, meaning it's fully withdrawn by £125,140. Someone earning £110,000 loses £5,000 of allowance, leaving £7,570 tax-free.

Step 3: Apply the income-tax bands

Income above the allowance is taxed in slices:

• 20% (basic rate) on income to £50,270
• 40% (higher rate) on income to £125,140
• 45% (additional rate) above £125,140

A £30,000 salary with no pension pays tax on £30,000 − £12,570 = £17,430 at 20% = £3,486.

Step 4: Add employee National Insurance

Employee NI in 2026/27 is 8% on earnings between £12,570 and £50,270, then 2% on anything above. On £30,000 that's £17,430 × 8% = £1,394.40.

Step 5: Student loan (if applicable)

Undergraduate plans deduct 9% of earnings above the plan's threshold; postgraduate loans deduct 6%. Details for each plan, including the specific thresholds, are in our guide to student loan plans and can be modelled precisely in the student loan repayment calculator.

Step 6: Put it all together

A £30,000 salary with no pension and no student loan works out at £30,000 − £3,486 − £1,394.40 = £25,119.60 a year, or £2,093.30 a month. A quick sanity check: divide take-home by gross to see your effective total tax rate — for this example, about 16.3%.

A second worked example: £60,000 salary

The maths scales the same way, just crossing into the higher-rate band. On £60,000 with no pension:

• Taxable income: £60,000 − £12,570 = £47,430
• Basic-rate slice: £37,700 (up to the £50,270 threshold) × 20% = £7,540
• Higher-rate slice: £9,730 (the remainder) × 40% = £3,892
• Income tax total: £11,432
• NI: £37,700 × 8% = £3,016, plus £9,730 × 2% = £194.60 → NI total: £3,210.60
• Take-home pay: £60,000 − £11,432 − £3,210.60 = £45,357.40 a year, or £3,779.78 a month

That's an effective combined tax-and-NI rate of about 24.4% — noticeably higher than the £30,000 example, because part of the income now sits in the 40% band.

Where the surprises hide

Two features regularly catch people out. The 60% effective tax trap between £100,000 and £125,140 combines 40% tax on the extra income with the loss of the personal allowance — for every additional £1 of gross salary in that band, you keep just 40p. And the NI kink at £50,270 doesn't reduce total pay but does mean each extra £1 delivers 58p rather than 68p as you cross from basic to higher rate on the tax side while NI drops from 8% to 2%.

Salary sacrifice — the quiet winner

Because salary-sacrifice pension contributions cut both income tax and NI, they often deliver the highest effective return in your compensation package. A basic-rate taxpayer sacrificing £100 gets it into their pension for a personal cost of £72; a higher-rate taxpayer for £58.

A quick payslip checklist

Before you query a figure with payroll, check these in order:

• Is your tax code correct — does it match the personal allowance you expect (1257L for the standard allowance)?
• Is your pension method salary sacrifice or relief-at-source — they show differently on a payslip.
• Does the NI category letter match your circumstances (most employees are category A)?
• Is a student loan plan flagged, and is it the right one?
• Does year-to-date tax look consistent with a steady monthly salary, or does it suggest a bonus month pushed you temporarily into a higher band?

Common questions

Is this the same as my personal tax code? Not always. Your tax code adjusts your allowance for benefits, previous under- or over-payments and other quirks — a code of 1257L means the standard £12,570 allowance.

What about bonuses? Bonuses attract the same tax and NI as regular pay, but they can temporarily push your monthly income into a higher band, meaning more tax at source. HMRC squares up over the tax year, so any overpayment usually washes out at year end.

Why does my colleague on the same salary take home more? Different pension contributions, tax codes, or benefits in kind — or a different student loan plan.

Does part-time or pro-rata pay change the calculation? No — the same allowance, bands and NI thresholds apply; only your gross pay figure changes. Our pro rata salary calculator is useful for working out the annual-equivalent figure first.
