The UK net salary calculator converts gross annual salary into the actual take-home pay (net pay) that an employee receives after deducting income tax, National Insurance (NI) contributions, student loan repayments (if applicable), and pension contributions. In 2024-25, the personal allowance is £12,570 — earnings up to this amount are tax-free. Income between £12,570 and £50,270 is taxed at 20% (basic rate), income between £50,270 and £125,140 at 40% (higher rate), and income above £125,140 at 45% (additional rate). Class 1 NI contributions are charged at 8% on earnings from £12,570 to £50,270, and 2% above £50,270. Under auto-enrolment, a minimum employee pension contribution of 5% of qualifying earnings applies (if opted in). Student loan repayments begin above £27,295 for Plan 2 (most post-2012 graduates) at 9% of income above the threshold. Scottish taxpayers face different income tax rates through devolved Scottish income tax, while Welsh taxpayers pay a Welsh Rate of Income Tax that mirrors England's rates. The calculator produces monthly, weekly, and daily breakdowns to help with budgeting.
Net Pay = Gross Pay - Income Tax - Class 1 NI - Student Loan (if applicable) - Pension Contribution (if applicable)
- 1Enter your gross annual salary; the calculator converts to monthly/weekly/daily if needed
- 2Calculate income tax using the progressive UK rate bands (0%/20%/40%/45%) after subtracting the personal allowance of £12,570
- 3Calculate Class 1 National Insurance: 8% on earnings £12,570-£50,270 and 2% on earnings above £50,270
- 4Deduct any student loan repayments (Plan 1: 9% over £24,990; Plan 2: 9% over £27,295; Plan 4 Scotland: 9% over £31,395; PG Loan: 6% over £21,000 — 2024-25 rates)
- 5Deduct pension contributions (minimum 5% of qualifying earnings under auto-enrolment; qualifying band £6,240-£50,270)
- 6Sum all deductions and subtract from gross pay to obtain net (take-home) pay
- 7For Scottish residents, apply Scottish income tax bands instead of England/Wales/NI bands (19%/20%/21%/42%/45%/48%)
Income tax ~£3,486; NI ~£1,380; student loan ~£246. Deductions total ~£5,112 from gross.
Tax: (£30,000 - £12,570) × 20% = £3,486. NI: (£30,000 - £12,570) × 8% = £1,394. Student loan: (£30,000 - £27,295) × 9% = £243. Net = £30,000 - £3,486 - £1,394 - £243 = £24,877.
Higher rate tax on income above £50,270; pension reduces taxable income
Tax: £7,540 basic rate + £1,892 higher rate = £9,432. NI: £3,016 + £96 = £3,112. Pension: £2,198 (auto-enrolment qualifying earnings). Net ≈ £40,258.
Personal allowance begins to taper away above £100,000, creating an effective 60% rate on income £100,001-£125,140
At exactly £100,000, the personal allowance is still fully in place. One extra pound of income starts the taper, making pension contributions highly valuable at this income level.
Tax: (£18,000 - £12,570) × 20% = £1,086. NI: (£18,000 - £12,570) × 8% = £434. Net: £18,000 - £1,520 = £16,480.
A part-time worker earning £18,000 pays relatively modest income tax and NI, retaining around 90% of gross earnings.

Pro Tip
If you are close to the £50,270 or £100,000 thresholds, consider making additional pension contributions to reduce your adjusted net income below the threshold. This can save significant amounts in income tax and NI by keeping you in a lower band.
Did you know?
In 1970-71, the top rate of UK income tax was 83% on earned income and 98% on investment income (the 'super tax'). Today's maximum rate of 45% for most taxpayers (48% in Scotland) represents a dramatic reduction in the highest marginal tax rates.
