Overtime Pay Calculator
Your pay for a week with overtime: time and a half, double time and the total.
Good to know. Time and a half on 8 extra hours is worth 12 regular ones. Evenings add up faster than they feel.

How it works
In plain words
Regular hours are paid at your normal rate. Overtime hours are paid at the normal rate times the overtime multiplier, usually 1.5. Double-time hours are paid at twice the normal rate. Add the three together.
The formula
total = rate × regular + rate × multiplier × overtime + rate × 2 × double time
Worked example
40 regular hours at 20 is 800. 8 overtime hours at 1.5 × 20 = 30 an hour is 240. Total pay: 1,040.00.

About the overtime pay calculator
Overtime is usually paid at a higher rate than regular hours. The most common is “time and a half”: 1.5 times your normal hourly rate. At 20 an hour, each overtime hour is worth 30, so a 48-hour week pays as much as 52 regular hours.
In the US, the Fair Labor Standards Act requires time and a half for hours over 40 in a workweek for most hourly (non-exempt) employees. Some states go further: California, for example, also pays overtime after 8 hours in a day and double time after 12. Salaried exempt employees usually aren’t owed overtime at all.
Elsewhere the rules come from contracts, collective agreements and national law rather than one federal rule. In the UK there is no legal right to overtime pay, but many employers pay time and a half or double time; in Canada, most provinces require time and a half after 40 or 44 hours. Enter the multiplier your contract uses: 1.25, 1.5 or 2.
The calculator works on one pay period, typically a week. All figures are before tax. Remember that overtime pay is taxed like the rest of your pay, so a big overtime week can put more of your pay into a higher tax bracket for withholding, even though your yearly tax is what matters in the end.
