How UK Take-Home Pay Is Calculated
David Mohamad · 19 March 2026
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 2025/26 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. A large pension 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 2025/26: the first £37,700 above your personal allowance is taxed at the basic rate (20%), and anything above that is taxed at the higher rate (40%) up to £125,140, then 45% on everything above.
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 2025/26: 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.
