Hourly Salary Calculator UK 2025

To convert hourly rate to annual salary, multiply your hourly rate by the number of hours you work per week, then multiply by 52 weeks. Formula: Hourly Rate × Hours per Week × 52 = Annual Salary. For example, £15/hour × 40 hours × 52 weeks = £31,200 annual salary.

£15 per hour equals £31,200 annually based on a standard 40-hour week (£15 × 40 × 52). If you work 37.5 hours, it would be £29,250 annually. After tax and NI on £31,200, you'd take home approximately £25,300 per year or £2,108 per month.

There's no legal definition in the UK, but full-time is typically considered 35-40 hours per week. Common standards are 37.5 hours (7.5 hrs × 5 days) or 40 hours (8 hrs × 5 days). The average UK full-time employee works around 36.4 hours per week.

The UK National Minimum Wage from April 2025 is: £12.21/hour for ages 21+, £10.00/hour for ages 18-20, and £7.55/hour for under 18s and apprentices. At £12.21/hour working 40 hours, you'd earn £25,397 annually.

To calculate your hourly rate from an annual salary, divide the salary by the total working hours in a year. Formula: Annual Salary ÷ (Hours per Week × 52) = Hourly Rate. For example, £35,000 ÷ (40 × 52) = £35,000 ÷ 2,080 = £16.83 per hour.
