Overtime pay calculator
An hourly rate, overtime hours and the multiplier you use, and out comes the overtime premium and the gross for the period. Gross pay only, and it computes no tax.

How the answer is worked out
Every step, in the open, so you can rebuild it in a few spreadsheet cells and disagree with it if you want to. A calculator you cannot check is an ad.
The overtime rate
Each tier of overtime is paid at the regular hourly rate multiplied by the multiplier you set for that tier. A rate of 25 at a tier 1 multiplier of 1.5 is an overtime rate of 37.50 an hour. The multiplier is your input, because whether overtime is time and a half, double time or something your contract sets is not a number this site will assume.
Overtime pay and the premium
Overtime pay for a tier is the overtime rate for that tier multiplied by the hours in it, and the two tiers are added together. The premium is the part above plain time: the overtime pay minus what those same hours would have cost at the regular rate. It is the extra the multiplier costs you, which is often the figure a budget actually wants.
The gross, and what is not in it
The gross for the period is the regular pay, which is the rate times the regular hours you entered, plus the overtime pay. Every figure is gross. The tool computes no tax and no deductions, and it holds no statutory overtime threshold, daily or weekly, because those differ by country and are yours to apply.
What this tool does not know
What the law requires. Overtime thresholds, the point at which a premium is due, mandatory multipliers and which hours count all differ by country and sometimes by contract, and this tool asserts none of them: the multiplier and the hours are figures you enter from your own rules. It gives you the arithmetic of the overtime you describe, not a ruling on whether it is owed.
It also computes no tax. Every figure is gross. To turn an annual salary into the hourly rate this tool starts from, use the annual to hourly pay converter, and to read a pay rise use the salary raise calculator. For the wider context, see the guide to running a compensation review.
Questions with complete answers
How is overtime pay worked out here?
Each overtime tier is the regular hourly rate multiplied by the multiplier you set, then multiplied by the hours in that tier. The two tiers are added for total overtime pay, and the gross is regular pay plus overtime pay. Every line is shown in the working so you can check it rather than trust it.
Why do I have to enter the multiplier myself?
Because there is no single correct multiplier. Time and a half, double time, a flat premium or a rate your contract or collective agreement sets are all possible, and the point at which overtime even begins differs by country. A fixed number would look authoritative and be wrong for most people, so the multiplier and the hours are yours, and the tool shows the arithmetic it did with them.
Is this gross or take-home pay?
Gross, and only gross. The tool works on the hourly rate you enter and computes no tax, because tax bands and social contributions differ by country, change over time and are not the kind of number this site will invent. For net pay, take the gross figure to your payroll partner or an official calculator for the country concerned.
What are the two tiers for?
Many overtime rules pay a first band at one multiplier and a further band at a higher one, for example time and a half up to a point and double time beyond it. The second tier lets you model that. If you only have one overtime rate, leave the tier 2 hours at zero and it drops out of the result.
Is anything I type saved or sent anywhere?
No. It computes in your browser and nothing is sent anywhere. There is no email wall, no account and no storage. The link button puts your figures in the address itself if you want to send them to someone, and pay figures are sensitive, so think before you paste that link somewhere public.
Overtime is arithmetic. The hours behind it are a record worth keeping.
