Understanding Your Take-Home Pay: Hourly to Salary Conversion

If you’ve ever asked yourself “whats my take home pay” from an hourly rate, you’re not alone. Many UK employees and job seekers need to convert hourly wages into annual or monthly figures to compare job offers, budget, or plan for the future. The answer depends heavily on the number of hours you work each week, whether you’re full-time or part-time, and the tax and National Insurance rules that apply.

The Standard Conversion Rule

The most common method used by employers and HMRC is simple: multiply your hourly rate by your contracted weekly hours, then by 52 weeks. For example, if you earn the 2026 National Living Wage of £12.71 per hour and work 37.5 hours a week, your gross annual salary is:

£12.71 × 37.5 × 52 = £24,784.50

From that, you subtract Income Tax (after the £12,570 Personal Allowance) and National Insurance (8% on earnings between £12,570 and £50,270, then 2% above). According to payslipchecker.uk, the take-home pay for this scenario is about £1,780 per month.

If you work a different number of hours, the same formula applies. A part-time worker on the same rate for 20 hours a week would earn £12.71 × 20 × 52 = £13,218.40 gross per year. Because this is below the Personal Allowance, no Income Tax or National Insurance is due, so take-home pay equals gross pay – about £1,101 per month.

Full-Time vs Part-Time: What the Data Says

The Office for National Statistics (ONS) Annual Survey of Hours and Earnings (ASHE) for 2025 shows that median weekly earnings for full-time employees were £766.60, while part-time employees earned a median of £280.00 per week. Full-time is defined as more than 30 paid hours per week (or 25 for teaching professions). Part-time is 30 hours or fewer.

These figures highlight the significant difference in earnings between the two groups. However, hourly rates can vary widely by occupation, region, and age. The National Living Wage applies to all workers aged 21 and over, regardless of hours, so part-time workers on the minimum wage earn the same hourly rate as full-time colleagues.

Why Hours Assumptions Matter

When you see a job advert with an annual salary, the hourly equivalent depends on the assumed working week. For example, a £30,000 salary works out to £15.38 per hour at 37.5 hours per week, but £14.42 per hour at 40 hours per week. Always check the contracted hours before comparing offers.

Some online calculators use 52.14 weeks (365.25 days ÷ 7) instead of 52, but the difference is tiny – less than £40 per year on a minimum wage salary. The PAYE system runs on 52 weeks, so that’s the standard to use.

Take-Home Pay After Tax and Deductions

Your take-home pay is what’s left after Income Tax, National Insurance, pension contributions, and any student loan repayments. For the 2026/27 tax year, the Personal Allowance is £12,570. Above that, basic rate tax is 20% on the next £37,700, then 40% up to £125,140, and 45% above. National Insurance is 8% on earnings between £12,570 and £50,270, then 2% above.

Pension contributions can significantly reduce your take-home pay if they are made before tax (e.g., via salary sacrifice). For example, workcalc.co.uk shows that a teacher on £40,000 paying 8.9% into the Teachers’ Pension Scheme takes home £29,471.60 per year, or £2,455.97 per month.
