UK Hourly to Annual Salary Conversion — Key Reference Rates and Tax Implications

Converting between hourly and annual pay is more nuanced than multiplying by 52 weeks. The number of paid hours per week, whether holidays are paid, overtime rates and part-time arrangements all affect the final figure. This converter handles all combinations and includes the 2026/27 National Minimum Wage check and take-home pay calculation.

Unpaid overtime can push effective pay below NMW

If you are contracted to 37.5 hours/week but regularly work 45+ hours unpaid, your effective hourly rate may fall below the National Living Wage — which is illegal regardless of your job title or salary level. The NMW applies to all workers except those who are genuinely self-employed. Calculate your effective hourly rate by dividing your gross weekly pay by actual hours worked.

Frequently Asked Questions

How do I convert an hourly rate to an annual salary?

Annual salary = Hourly rate × Hours per week × Paid weeks per year. For 37.5 hours/week, 52 paid weeks: multiply by 1,950. For 40 hours/week: multiply by 2,080. For part-year or term-time work: multiply by actual paid weeks. Example: £18/hour × 37.5 hours × 52 weeks = £35,100 gross annual salary.

What is the UK National Living Wage in 2026?

The National Living Wage (for workers aged 21+) is £12.21/hour from April 2026, following the annual April uprating. This equates to approximately £23,810/year for a 37.5-hour week or £25,397 for a 40-hour week. Employees under 21 receive lower NMW rates. Employers must pay at least the NMW — paying below is illegal and subject to significant penalties.

Does overtime change my annual salary significantly?

Yes. At £18/hour, 5 hours of overtime per week at 1.5× rate adds £7,020 gross to your annual earnings — approximately a 20% boost on a £35,100 base salary. After tax, overtime income is taxed at your marginal rate, so a basic-rate taxpayer keeps approximately 72% of overtime gross (after income tax and NI). Our calculator includes the overtime premium in the annual total.
