How the overtime math works
Hours up to your overtime threshold pay at your regular rate; everything beyond it pays at the overtime rate — your regular rate times the multiplier. The US federal baseline (FLSA) is 1.5× after 40 hours in a workweek, which is where “time and a half” comes from.
Worked example: 46.5 hours at $18/hour with a 40-hour threshold splits into 40 regular hours (40 × $18 = $720) and 6.5 overtime hours at $27 (6.5 × $27 = $175.50) — total gross pay $895.50.
The threshold and multiplier are adjustable because rules differ: some US states add daily overtime (California requires 1.5× after 8 hours in a day and 2× after 12), many countries set weekly thresholds other than 40, and some contracts pay double time for holidays. This calculator does the arithmetic for whatever rule applies to you — it isn't legal advice.
Frequently asked questions
How is overtime pay calculated?
Multiply your regular hourly rate by the overtime multiplier — usually 1.5 — then by the overtime hours. At $18/hour, time and a half is $27/hour, so 6 overtime hours pay 6 × $27 = $162 on top of regular wages.
What is time and a half of my rate?
Time and a half is your hourly rate multiplied by 1.5. For example, $15 becomes $22.50, $18 becomes $27, and $22 becomes $33 per overtime hour. Enter your rate in the calculator to see it exactly.
When does overtime start?
Under the US federal FLSA, overtime starts after 40 hours in a workweek for non-exempt employees. Some states add daily overtime — California, for example, requires overtime after 8 hours in a single day — and some contracts or countries use different thresholds, which is why the threshold is adjustable here.
What is double time and when does it apply?
Double time is twice the regular rate. Federal law does not require it, but some states and union contracts do — California requires double time after 12 hours in a day, and some employers pay it for holidays. Switch the calculator to 2× to compute it.
Does this calculator give legal or tax advice?
No — it does the arithmetic. Overtime eligibility depends on your jurisdiction, your exemption status, and your contract, and the figures here are gross pay before taxes and deductions. Check your local labor rules or payroll department for the rules that apply to you.
