How to calculate overtime pay
Weekly gross = (rate × regular hours) + (rate × overtime multiplier × overtime hours) + (rate × double-time multiplier × double-time hours).
For $20 an hour with 40 regular hours, 5 hours at 1.5x and 2 hours at 2x:
| Pay type | Hours | Rate | Pay |
|---|---|---|---|
| Regular | 40 | $20 | $800 |
| Overtime | 5 | $30 | $150 |
| Double time | 2 | $40 | $80 |
| Weekly gross | 47 | $1,030 |
The annualized figure is $1,030 × 52 = $53,560, which assumes every week looks like this one. Few do, so read it as a rough scale. Both multipliers can be edited to match your contract.
If you are salaried, the tool divides salary by contract hours × 52. $52,000 on 40 hours gives $25 an hour. Your legal rate may differ: US rules build the regular rate from all pay for work, so some bonuses can raise it.
Overtime rules in the US, UK, India and Pakistan
What follows is a general summary, not legal advice. Your contract and local law decide what you are owed.
United States
Under the FLSA, covered employees generally get at least 1.5x their regular rate for hours over 40 in a workweek. Hours cannot be averaged across weeks, and weekends and holidays earn no federal premium as such. Double time is a matter for contracts and some states: California requires 2x after 12 hours in a day.
A salary alone does not make you exempt. Exempt status generally requires a duties test and at least $684 a week, and job titles do not decide it.
United Kingdom
GOV.UK says employers do not have to pay for overtime, though your average pay for all hours must not fall below the minimum wage. Your contract sets any premium. For a rough check, divide total pay by total hours.
India
The OSH Code, 2020 replaced the Factories Act, 1948 from 21 November 2025. Section 27 sets overtime at twice the rate of wages and requires the worker's consent. A Labour Ministry FAQ describes the trigger as more than 8 hours a day for a daily wager, or 48 hours a week. State rules also apply, so check yours.
Pakistan
Section 47 of the Factories Act, 1934 sets twice the ordinary rate for non-seasonal factory work over 9 hours a day or 48 a week. That ILO copy runs only to 1981, and provinces have since passed their own factory laws, so check the current act for your province.
For factory work in India or Pakistan, set the overtime multiplier to 2.
How to check your payslip for overtime
- Add up your hours for the pay period. The time card calculator can do this from your clock times.
- Find your contract's overtime terms, including the hours that trigger the premium.
- Enter the hours and multipliers here and compare the result with your gross pay.
- Look for a pattern. One small gap might be timing. The same gap every month deserves a question.
- Take your numbers to payroll or HR and ask how they calculated the figure.
