Hourly to salary calculator
Convert an hourly rate into daily, weekly, monthly and annual pay — or work backwards from a salary to find the hourly rate it really represents.
Your result
| Period | Gross pay | Hours |
|---|---|---|
| Per hour | — | 1 |
| Per day | — | — |
| Per week | — | — |
| Per month | — | — |
| Per year | — | — |

The conversion, step by step
Going from an hourly rate to a salary takes two multiplications. Your rate times your weekly hours gives gross weekly pay; that times your paid weeks gives the annual figure. Someone on £15 an hour over a 37.5-hour week and 52 paid weeks earns £562.50 a week and £29,250 a year.
Going the other way, divide. The annual salary divided by the total hours you work in a year — weekly hours times paid weeks — gives the hourly rate. This is the number worth knowing when a job is advertised as a salary but you want to compare it against hourly work.
The monthly figure always comes from dividing the annual by twelve, never from multiplying the weekly by four. A calendar month averages about 4.35 weeks, so the four-week shortcut understates monthly pay by roughly eight per cent.
Where the common shortcuts go wrong
The best-known trick is to double your hourly rate and add three zeros: £15 an hour becomes "about £30,000". It works because 40 hours over 52 weeks is 2,080 hours, close enough to 2,000 for mental arithmetic.
It quietly assumes a 40-hour week, though. On the 37.5-hour week that most UK full-time contracts specify, the annual total is 1,950 hours, and the shortcut overstates your pay by nearly seven per cent — around £2,000 on a £30,000 salary. Anyone part-time, on a compressed week, or working shifts should ignore it entirely.
The other trap is paid weeks. Employees are paid across all 52 weeks, holiday included, so 52 is correct. Contractors, seasonal staff and term-time workers are not, and using 52 for them inflates the annual figure by exactly the weeks they do not get paid for.
Frequently asked questions
How do I convert an hourly rate to an annual salary?
Multiply your hourly rate by the hours you work each week, then multiply that by the number of paid weeks in your year. For someone on £15 an hour working 37.5 hours across 52 paid weeks, that is 15 × 37.5 × 52, giving £29,250 a year before tax.
Should I use 52 weeks or 48?
Use 52 if your holiday is paid, which is the case for most employees — you are paid across the whole year including your leave. Use a lower figure only if you genuinely are not paid for time off, as with some casual, seasonal or term-time work, or if you are quoting a contractor rate where unpaid weeks are real.
Why does the monthly figure not match my payslip?
Two reasons. This shows gross pay, before income tax, National Insurance, pension and any student loan repayment come off. And a month is not four weeks — it averages about 4.35 — so dividing the annual figure by twelve gives a higher monthly number than multiplying weekly pay by four.
Is the 2,080 hour shortcut accurate?
It is a reasonable rule of thumb for a 40-hour week over 52 weeks, and it is where the common advice to double your hourly rate and add three zeros comes from. It misleads anyone not on a 40-hour week — a 37.5-hour UK week is 1,950 hours, which makes the shortcut overstate annual pay by nearly seven per cent.
