UK Take Home Pay Calculator: What Is Your Salary After Tax in 2025?

A UK employee earning £40,000 gross per year takes home approximately £31,920 after income tax and National Insurance, or about £2,660 per month. The exact figure depends on your tax code, pension contributions, student loan repayments and whether you pay into a salary sacrifice scheme. For most employees on a standard 1257L tax code with no student loan, the effective deduction is roughly 20% of gross pay.

This guide explains how UK take home pay is calculated for 2025/26, what a salary calculator does behind the scenes, and how to account for deductions that reduce your net pay further. Use our UK salary calculator to see your exact take home pay based on your gross salary and circumstances.

What take home pay means

Take home pay (also called net pay) is the amount that actually reaches your bank account after all deductions. Gross pay is your salary before any deductions. The gap between gross and net is made up of income tax, National Insurance contributions, and any other deductions your employer makes, such as pension contributions, student loan repayments, or childcare voucher schemes.

When a job advert says £35,000 per year, that is almost always the gross figure. Your actual spending power is the net amount. Understanding this difference is essential for budgeting, comparing job offers, and negotiating salary, particularly when one role offers a higher gross salary but the other has better pension contributions or benefits that affect your net position.

Income tax bands for 2025/26

UK income tax is charged in bands. Everyone receives a personal allowance of £12,570, which is tax-free. Earnings between £12,571 and £50,270 are taxed at the basic rate of 20%. Earnings between £50,271 and £125,140 are taxed at the higher rate of 40%. Earnings above £125,140 are taxed at the additional rate of 45%.

For a detailed explanation of how these bands work and how the personal allowance is tapered for high earners, see our UK income tax bands guide for 2025. For a broader overview of salary after tax, read our UK salary after tax guide.

National Insurance contributions

Employee National Insurance is charged separately from income tax. For 2025/26, you pay 8% on earnings between £12,584 and £50,284 per year, and 2% on earnings above £50,284. These thresholds are slightly different from the income tax bands, which is why the combined effective rate does not map neatly to a single percentage.

National Insurance is calculated per pay period (weekly or monthly) rather than cumulatively across the year in the same way as income tax. This means your NI deduction is consistent each month, while income tax may vary if you receive bonuses or have a change in tax code mid-year.

How NI interacts with income tax

Both income tax and NI are deducted from your gross pay, but they use different thresholds and rates. On a £40,000 salary, you pay approximately £5,480 in income tax and £2,291 in employee NI, giving total deductions of roughly £7,771 and take home pay of about £32,229. The effective combined rate is approximately 19.4%.

For higher earners, the marginal rate of combined income tax and NI on earnings between £50,270 and £100,000 is effectively 42% (40% income tax plus 2% NI). Above £100,000, the personal allowance taper can push the marginal rate even higher on a portion of income.

How a UK salary calculator works

A salary calculator takes your gross annual or monthly pay and applies the current tax and NI rules to estimate your net pay. The calculation follows the same logic as your employer's payroll system. Enter your gross salary, select your pay frequency (annual, monthly, weekly), and the calculator shows your income tax, NI, and take home amount.

More advanced calculators let you add optional deductions: student loan plan (Plan 1, 2, 4, or Postgraduate), pension contribution percentage, and tax code adjustments. These options make the estimate more accurate for your specific situation. A basic calculator without these options gives a good approximation for employees on standard codes with no additional deductions.

Use the UK salary calculator to model your take home pay at different salary levels and see how crossing a tax band boundary affects your net income.

Student loan repayments

If you have a student loan, repayments are deducted from your salary through PAYE once your income exceeds the threshold for your plan. For Plan 2 (loans taken out from 2012 onwards in England and Wales), the threshold is £27,295 per year and you repay 9% of income above that threshold. For Plan 1, the threshold is lower at £24,990. Plan 4 (Scotland) uses a threshold of £31,395. Postgraduate loans have a separate £21,000 threshold at 6%.

Student loan repayments are not tax-deductible, but they are deducted after tax and NI. On a £35,000 salary with a Plan 2 loan, you repay 9% of (£35,000 minus £27,295), which is 9% of £7,705, equalling £693.45 per year or about £57.79 per month. This further reduces your take home pay beyond tax and NI.

Pension contributions and salary sacrifice

Workplace pension contributions reduce your take home pay but also reduce your income tax and NI liability. If you contribute 5% of your £40,000 salary (£2,000) into a pension through a net pay arrangement, your taxable pay drops to £38,000, saving you approximately £400 in income tax and £160 in NI. Your employer may also contribute, typically 3% to 5%, which does not come out of your pay.

Salary sacrifice schemes work similarly but with a structural difference: you agree to reduce your gross salary in exchange for a benefit (pension, cycle to work, electric vehicle, childcare). Because the sacrifice happens before tax and NI, you save on both. A £2,000 salary sacrifice for pension saves the same tax and NI as a £2,000 net pay contribution, but the mechanism is different on your payslip.

Tax codes and why yours might differ

The standard tax code for 2025/26 is 1257L, which gives you the full personal allowance of £12,570. If your tax code is different, your take home pay will differ from what a standard calculator shows. Common variations include BR (all income taxed at basic rate, no personal allowance), D0 (all at higher rate), and K codes (where you owe tax from previous underpayments or benefits).

If you receive taxable benefits from your employer (a company car, private medical insurance, or living accommodation), HMRC reduces your personal allowance through your tax code. A code of 1000L instead of 1257L means £2,570 less tax-free allowance and approximately £514 more income tax per year. Check your tax code on your payslip and query anything unexpected with HMRC.

Monthly vs annual take home pay

Most UK employees are paid monthly. To convert annual take home pay to monthly, divide by 12. A net annual salary of £31,920 is £2,660 per month. Some employers pay on a 4-weekly or weekly cycle, which means you receive 13 or 52 payments per year respectively, affecting how deductions are calculated per pay period.

If you are comparing a monthly salaried role with a daily-rate contract, convert both to the same time period before comparing take home pay. A contractor charging £350 per day for 220 working days earns £77,000 gross, but must also account for employer NI, pension, and lack of paid holiday, which a simple salary calculator does not capture.

Worked example: £25,000 salary

On a £25,000 gross salary with a 1257L tax code and no student loan, the personal allowance of £12,570 covers the first portion of income. Taxable income is £12,430, taxed at 20%, giving income tax of £2,486. Employee NI is 8% on earnings above £12,584, applied to (£25,000 minus £12,584), which is £12,416 at 8%, giving NI of £993.28.

Total deductions are approximately £3,479. Take home pay is approximately £21,521 per year, or £1,793 per month. The effective deduction rate is about 13.9%, reflecting the significant tax-free portion from the personal allowance.

Worked example: £50,000 salary

On £50,000 gross, taxable income after the personal allowance is £37,430. Income tax is £7,486 (20% on £37,430). Employee NI is 8% on (£50,000 minus £12,584), which is £37,416 at 8%, giving NI of £2,993.28. Total deductions are approximately £10,479. Take home pay is approximately £39,521 per year, or £3,293 per month.

At £50,000 you are just below the higher-rate threshold. An extra £1,000 in gross pay would push £1,000 into the 40% band, but only the income tax portion increases at the higher rate. The marginal deduction on that extra £1,000 is approximately 40% income tax plus 2% NI, or about 42%.

Worked example: £80,000 salary

On £80,000 gross, the first £37,700 above the personal allowance is taxed at 20% (£7,540), and the remaining £29,730 is taxed at 40% (£11,892). Total income tax is £19,432. Employee NI is 8% on the band up to £50,284 (£3,016) plus 2% on the amount above (£29,716 at 2% = £594.32), giving total NI of £3,610.32.

Total deductions are approximately £23,042. Take home pay is approximately £56,958 per year, or £4,747 per month. With a Plan 2 student loan, an additional 9% of (£80,000 minus £27,295) = £4,743.45 per year would be deducted, bringing net pay down to approximately £52,215.

Comparing job offers using take home pay

When comparing two job offers, look beyond the gross salary. A role offering £45,000 with a 10% employer pension contribution may be worth more in total compensation than a role offering £48,000 with a 3% pension contribution, even though the gross difference favours the higher salary. Factor in benefits, bonus structures, and any salary sacrifice opportunities.

Use a salary calculator to convert each offer to net pay, then add the value of employer pension contributions and other benefits. A £48,000 salary with 3% employer pension gives £1,440 in employer contributions. A £45,000 salary with 10% employer pension gives £4,500. The lower gross offer may deliver more total value.

Scottish income tax differences

Scotland sets its own income tax rates and bands. For 2025/26, Scottish taxpayers pay 19% on earnings between £12,571 and £15,397, 20% between £15,398 and £27,491, 21% between £27,492 and £43,662, 42% between £43,663 and £75,000, 45% between £75,001 and £125,140, and 48% above £125,140. National Insurance rates are the same across the UK.

If you live in Scotland, use a salary calculator configured for Scottish tax rates. The differences are most noticeable for earners between approximately £28,000 and £44,000, where Scottish rates are slightly higher, and for earners above £75,000, where the Scottish top rate of 48% exceeds the UK additional rate of 45%.
