Salary to Hourly Calculator

When this calculator helps

Knowing what an annual salary works out to per hour turns an abstract number into something you can actually compare. Reach for this calculator when you are weighing a salaried offer against day-rate contracting or freelance work, sizing up a part-time role against a full-time one, or simply trying to put a value on an hour of your time before you agree to extra unpaid hours. A £39,000 job and a £42-an-hour contract are not easy to compare until both are in the same units.

It is just as useful for the quieter decisions: whether a promotion that adds five hours a week is really a raise once you divide the new salary by the new hours, or how a job that demands long unpaid evenings stacks up against one that respects a 37.5-hour week. Because you can set any working week and any number of paid weeks, you can model a UK contract exactly as it is written rather than relying on a one-size-fits-all assumption.

How to read your result

The hourly figure the calculator returns is gross — the rate before income tax, National Insurance, pension contributions and any salary sacrifice come out. For a basic-rate taxpayer the amount that actually reaches your bank account is usually around 70 to 80 per cent of the gross hourly shown, so treat this as the headline rate, not your take-home.

The figure also depends entirely on the two inputs you choose: your contracted hours per week and the number of paid weeks. Because a UK salaried role pays you through your statutory holiday, the honest divisor is 52 weeks, not the weeks you are physically at your desk. Change the hours to match your contract — 35, 37.5 and 40 all give noticeably different hourly rates from the same salary — and the result moves accordingly.

A worked example

Take a £39,000 salary on a standard 37.5-hour week, paid across all 52 weeks of the year. That is 1,950 paid hours, so the gross hourly comes to £20.00. Now suppose the same role actually expects 42 hours most weeks but only pays for 37.5: dividing £39,000 by the 42 hours you really work drops the effective rate to about £17.86 an hour, which is the truer picture of what your time is earning. Flip it the other way and a 35-hour City week on the same salary lifts the rate to roughly £21.43, showing how much the contracted week matters.

Common mistakes to avoid

Most errors come from picking the wrong divisor or from comparing two numbers that are not really comparable.

• Dividing by every hour in the calendar year rather than your contracted working hours — that badly understates the rate, because UK salaried staff are paid through their holiday weeks.
• Treating the gross hourly as what a contractor should charge — a freelancer must load on holiday cover, pension, sick pay, equipment and gaps between contracts, so a fair day rate is well above the salaried equivalent.
• Forgetting the value of benefits — employer pension contributions, private healthcare and paid sick leave are real pay that never appears in the hourly figure.
• Comparing your gross hourly directly against a net take-home rate someone else quoted; always compare like for like.

UK working hours and paid holiday

A typical UK full-time week is 37.5 hours — a 7.5-hour day across five days with an unpaid lunch — though 35 hours is common in finance and 40 in retail and the trades. On top of that, UK workers are entitled to 5.6 weeks (28 days) of statutory paid holiday, and that paid time off is the reason the naive 'salary divided by 2,080 hours' sum used in some countries does not fit here.

Because those holiday weeks are paid, a salaried UK worker actually performs roughly 46 to 47 weeks of work for a full year's salary. Dividing the salary across all 52 paid weeks, as this calculator does, gives the rate your contract really pays — but if you instead want the value of an hour genuinely worked, divide by the smaller number of weeks you are at your desk and the hourly figure rises. That gap between paid hours and worked hours is exactly what makes UK and EU hourly rates look lower than a crude annual-hours division would suggest.
