How UK Take-Home Pay Is Calculated

Every UK take-home pay result follows the same basic steps. Your gross salary goes in at the top and your take-home pay comes out at the bottom, with deductions removed along the way.

Where calculators and payslips differ is in how — and at which step — pension is taken off. That one choice changes every number that comes after it.

Gross Salary

Your total salary before any deductions. This is the number on your contract. Everything else is worked out from this figure.

Pension Contributions

If you make pension payments through your employer, these can reduce your pay before other deductions are calculated. How much they reduce depends on the type of pension you have.

With salary sacrifice, pension comes off your gross before tax and NI. With NET pay, pension lowers your taxable income but not your NI. With relief at source, pension is taken from your net pay and your provider claims back basic-rate tax.

Personal Allowance and Taxable Income

Everyone gets a personal allowance — the amount you can earn tax-free. For 2026-27 this is £12,570. Your taxable income is your gross salary (after any pension reduction) minus this allowance.

If you earn above £100,000, your personal allowance is tapered: you lose £1 of allowance for every £2 earned above the threshold. By £125,140, the allowance is gone entirely.

Personal Allowance Taper

For every £2 you earn above £100,000, £1 of your personal allowance is removed. This means your allowance falls to zero at £125,140.

In the taper zone, you pay 40% tax on each extra pound you earn — plus 40% on the withdrawn allowance. That gives an effective marginal rate of 60% on income between £100,000 and £125,140.

NHS staff on Band 8d and above typically have base salaries in this range. The taper is a key reason higher earners see a disproportionate drop in take-home pay.

Salary sacrifice reduces your gross income before the taper applies. A large enough contribution can bring you back below £100,000 and restore some or all of your allowance.

Income Tax

Tax is charged in bands. For rest-of-UK (England, Wales, Northern Ireland) in 2026-27:

• Basic rate (20%) — the first £37,700 above your personal allowance (gross up to £50,270).
• Higher rate (40%) — earnings from £50,270 to £125,140.
• Additional rate (45%) — everything above £125,140.

Scotland has its own income tax bands with more brackets and different rates. The starter rate (19%) and intermediate rate (21%) mean Scottish taxpayers on lower and middle incomes pay slightly different amounts.

National Insurance

National Insurance is a separate charge from income tax with different thresholds. For 2026-27: 8% on earnings between £12,570 and £50,270, then 2% above that. NI funds state benefits like the State Pension.

Student Loan

Student loan repayments are calculated as a percentage of earnings above a plan-specific threshold. Plans 1, 2, 4, and 5 charge 9%; Postgraduate loans charge 6%. These come off after tax and NI.

Take-Home Pay

After income tax, National Insurance, pension, and student loan are all deducted, what remains is your take-home pay — the amount that lands in your bank account.

Why Pension Method Matters

The pension method changes where in the pipeline your pension is deducted, which affects every number after it. Two people with the same salary and the same pension amount can have different take-home pay because of the method used.
