How this was worked out

    The formula

    hourly pay = annual salary ÷ (hours a week × 52)

    Where it comes from

    To turn a salary into an hourly figure you have to go up to the year first and back down to the hour, because the year is the only period that does not depend on how the pay is split or how the week is arranged. With the annual salary and the hours in the year, the division is then direct.

    How to work it out by hand

    1. Multiply your monthly salary by the number of instalments a year
    2. Multiply your weekly hours by 52 to get the hours in the year
    3. Divide the annual salary by the hours in the year
    4. Check the hours are the ones you really work, not the ones in the contract

    What is worth knowing

    The commonest mistake is treating a month as four weeks. A month is 52 ÷ 12 = 4.33 weeks, so dividing a monthly salary by 160 hours instead of 173.33 inflates the rate by 8.33 %. The second is forgetting extra instalments: on fourteen payments the payslip shows one figure while the real monthly average is 16.7 % higher. The third is counting contracted hours when you work more: every unpaid hour lowers your real hourly pay without the payslip changing at all.

    Frequently asked questions

    How many working hours are there in a month?

    On a 40-hour week, 173.33 hours a month: 40 × 52 ÷ 12. Not 160, which is what you get from counting four exact weeks.

    How do I turn a monthly salary into an hourly one?

    Multiply the monthly figure by the instalments you receive a year and divide by the hours in the year. On 2,000 a month over fourteen instalments and a 40-hour week, that is 13.46 an hour.

    Is this on gross or on net pay?

    On whatever you type in. Put in your gross and you get gross per hour; put in what actually lands in your account and you get what you really earn per hour, which is the figure to compare offers with.

    Why does my hourly pay drop when I do unpaid overtime?

    Because the annual salary stays the same while the hours go up. Entering your real hours instead of the contracted ones is what makes the calculation honest.
