What this calculator covers and how the numbers are worked out
This tool converts an hourly pay rate into an annual gross salary, which is useful whether you're comparing a job that pays by the hour against one advertised as a yearly salary, or just want to know what a rate translates to over a full year of work.
The formula is straightforward: annual pay equals your hourly rate multiplied by the hours you work each week, multiplied by the number of weeks you're actually paid for in the year. Getting an accurate annual figure depends mostly on getting that weekly hours and weeks-paid figure right for your own situation.
There's no legal definition of 'full time' in the UK, but most full-time roles fall somewhere between 37.5 and 40 hours a week, so that's a reasonable default if you're not sure. Part-time and casual work can obviously be any number of hours below that.
Here's a worked example for someone on a standard contract. Say your hourly rate is £13.50, you work 37.5 hours a week, and you're paid for all 52 weeks of the year because your holiday is paid. Your annual gross pay would be £13.50 × 37.5 × 52 = £26,325.
The number of weeks you use matters as much as the hourly rate itself. If you're paid for your annual leave, as most employees are, use 52 weeks, since you're effectively paid every week of the year even when you're on holiday. But if you're on a contract where some weeks genuinely go unpaid, for example a term-time-only role in a school, you need to reduce the weeks accordingly. A term-time worker paid £15 an hour for 30 hours a week across 39 paid weeks a year would earn £15 × 30 × 39 = £17,550 annually, notably less than if you incorrectly assumed 52 weeks.
It's worth being clear that this calculation always produces a gross figure, meaning it's your pay before any income tax, National Insurance or pension contributions are taken off. It tells you what you're paid, not what lands in your bank account.
Once you have your annual gross figure from this tool, you can feed it straight into the Salary Calculator on this site to see an estimate of your actual take-home pay after tax, National Insurance and any pension contribution or student loan repayment.
This is also a handy way to sanity-check a job advert. Recruitment ads sometimes quote an hourly rate for what is effectively a salaried role, or quote a day rate without saying how many hours a day covers. Converting everything to the same annual gross figure makes it much easier to compare offers that are presented in different formats, rather than trying to judge which sounds better from the headline number alone.
Use 52 if you're paid for your annual leave, which covers most employees. If some weeks genuinely go unpaid, such as a term-time-only contract, reduce the weeks to the number you're actually paid for.
It's always gross, meaning before income tax, National Insurance and any pension contribution. Put the resulting annual figure into the Salary Calculator to see an estimated take-home amount.
Use your average weekly hours across the year for the most realistic estimate, since the calculation assumes a consistent number of hours each paid week.
There's no fixed legal definition, but 37.5 to 40 hours a week is typical for full-time roles, so it's a reasonable starting point if your contract doesn't specify.
Use the actual number of weeks you're paid for rather than 52. A school support role paid for 39 weeks a year, for example, should use 39 in the calculation, not the full 52.
No, it's based on your regular contracted hourly rate and hours. If you regularly work paid overtime, you'd need to add that separately, for example using the Overtime Pay Calculator.
No, the pay frequency doesn't change your total annual pay, only how often you receive it, so the calculation gives the same annual figure regardless of your pay schedule.
Take the annual gross figure this tool gives you and enter it into the Salary Calculator, which applies income tax, National Insurance, pension and student loan deductions to show your take-home pay.
Not usually, as long as you're paid as normal for bank holidays like the rest of your annual leave; keep the weeks figure at 52. It would only matter if your contract treats bank holidays as unpaid, which is unusual for employees.
