Understanding Your Salary After Tax: Hourly, Weekly, and Annual Pay in the UK

Understanding Your Salary After Tax: Hourly, Weekly, and Annual Pay

When you're offered a job or planning your finances, knowing your salary after tax is essential. The amount you see on your contract (gross pay) is rarely what lands in your bank account. Deductions for Income Tax, National Insurance, and possibly pension or student loans all reduce your take-home pay. For UK workers on minimum wage or hourly rates, the relationship between hourly, weekly, and annual pay can be confusing. This guide explains how your salary after tax is calculated and what to expect at different pay frequencies.

Hourly Rates and Statutory Minimums

The UK government sets statutory minimum wages that change each April. For 2026/27, the rates are:

• National Living Wage (21+): £12.71 per hour
• National Minimum Wage (18–20): £10.85 per hour
• National Minimum Wage (under 18): £8.00 per hour
• Apprentice rate: £8.00 per hour

These are the legal minimums. Many employers pay more, especially in sectors like retail, hospitality, and healthcare. Your actual hourly rate determines your gross weekly and annual earnings, which then feed into your salary after tax calculation.

From Hourly to Weekly to Annual Gross Pay

Your gross pay depends on your hourly rate and the number of hours you work each week. A standard full-time week is often 37.5 or 40 hours, but part-time roles are common. Here’s how the National Living Wage converts:

• 40 hours/week: £12.71 × 40 = £508.40 gross per week; £26,437 gross per year
• 37.5 hours/week: £12.71 × 37.5 = £476.63 gross per week; £24,785 gross per year

For the 18–20 rate at 40 hours: £10.85 × 40 = £434.00 per week; £22,568 per year. For under 18/apprentice at 40 hours: £8.00 × 40 = £320.00 per week; £16,640 per year.

These annual figures are the starting point for calculating your salary after tax.

How Take-Home Pay Is Calculated

Your employer uses the PAYE system to deduct Income Tax and National Insurance. For 2026/27, the standard tax code is 1257L, giving you a personal allowance of £12,570 – the amount you can earn before paying tax. Above that:

• Income Tax: 20% on earnings from £12,571 to £50,270
• National Insurance (employee): 8% on earnings from £12,571 to £50,270

Using these rules, a full-time worker on the National Living Wage (40 hours, £26,437 gross) pays:

• Income Tax: 20% of (£26,437 – £12,570) = £2,773
• National Insurance: 8% of (£26,437 – £12,570) = £1,109
• Total deductions: £3,882
• Take-home pay: £26,437 – £3,882 = £22,555 per year (£1,880 per month)

For a 37.5-hour week (£24,785 gross), take-home is approximately £21,364 per year (£1,780 per month). These figures are based on standard assumptions and no other deductions. Your actual salary after tax may differ if you have a different tax code, work in Scotland, contribute to a pension, or repay a student loan.

Why Pay Frequency Matters

Whether you are paid weekly, fortnightly, or monthly affects your cash flow but not your total annual salary after tax. However, the way deductions are applied per pay period can cause slight variations if your hours fluctuate. For example, if you are paid weekly and work overtime one week, you may pay more tax that week but it balances out over the year. Monthly paid workers see consistent deductions each month. Understanding your pay schedule helps you budget effectively.

Variations That Affect Your Take-Home Pay

Several factors can change your salary after tax from the standard figures:

• Scottish taxpayers: Different tax bands apply. The starter rate of 19% on earnings between £12,571 and £16,537 can reduce your tax bill slightly.
• Workplace pension: Auto-enrolment typically deducts 5% of qualifying earnings (between £6,240 and £50,270). At NLW rates, this reduces monthly take-home by about £84.
• Student loan repayments: If you have a Plan 1, 2, or 5 loan, repayments start once your earnings exceed the threshold (e.g., Plan 5: £25,000). This can reduce take-home by 9% of earnings above the threshold.
• Tax code adjustments: If you have a company car, owe underpaid tax, or have multiple jobs, your tax code may change, altering your deductions.

Always check your payslip to ensure the correct code is applied. For more detailed guidance, visit our pay guides section.

Comparing Hourly, Weekly, and Annual Pay

When job hunting, you may see salaries advertised as hourly, weekly, or annual. To compare offers, convert everything to an annual gross figure. For example:

• £12.71/hr × 40 hrs × 52 weeks = £26,437
• £10.85/hr × 37.5 hrs × 52 weeks = £21,158

Then use a salary after tax calculator to estimate take-home. Remember that hourly roles often offer overtime, which can boost your earnings but also increase tax and NI. Our UK Minimum Wage page has more information on statutory rates.

Part-Time and Variable Hours

If you work fewer than about 19 hours per week on the National Living Wage, your annual gross may fall below the personal allowance of £12,570. In that case, you pay no Income Tax, but National Insurance still applies if your weekly earnings exceed the primary threshold (roughly £242 per week). This means your salary after tax is closer to your gross pay, but you still lose a small amount to NI.

For example, working 15 hours per week at £12.71 gives gross £9,913.80 per year – below the tax threshold, so no Income Tax. National Insurance would be minimal or zero depending on weekly earnings. Your take-home is almost your full gross.

Using Salary Calculators

To get a precise estimate of your salary after tax, use a reputable online calculator. Many are available from tax software providers and government-backed sites. Enter your hourly rate, weekly hours, tax code, and any deductions like pension or student loans. The calculator will show your monthly, weekly, and annual take-home pay. Remember that these are estimates – your actual payslip may differ due to rounding or mid-year changes.
