Overtime calculator

Overtime is paid at a higher rate for hours worked beyond the standard working time. Calculating it correctly matters for both employees checking their payslips and employers running payroll. This calculator splits hours into regular and overtime tiers, applies the multipliers and shows total pay and the effective hourly rate.

How to use it

1. Enter the base hourly rate.
2. Enter regular hours and overtime hours for each rate tier, such as 1.5x and 2x.
3. Read regular pay, overtime pay, total gross pay and the effective hourly rate.

The formula

• Regular pay = regular hours × base rate
• Overtime pay = Σ (overtime hours × base rate × multiplier)
• Effective hourly rate = total pay / total hours

Worked example

Base rate 20 per hour, 40 regular hours, 6 hours at 1.5x and 2 hours at 2x:

• Regular pay: 40 × 20 = 800
• Time and a half: 6 × 30 = 180
• Double time: 2 × 40 = 80
• Total: 1,060 for 48 hours, an effective rate of 22.08 per hour.

Common rules (check local law)

• United States (FLSA): non-exempt employees get at least 1.5x for hours over 40 in a workweek. Some states, such as California, also require daily overtime and double time.
• India: the Factories Act sets overtime at twice the ordinary rate of wages beyond the daily or weekly limits.
• UK: there is no legal right to overtime pay, but average pay must not fall below the minimum wage.

Contracts and collective agreements often grant more generous rates for weekends, nights and public holidays.
