Overtime pay calculator
Add ordinary hours and up to three named overtime rates for one pay period, using the hourly rate and full-pay multipliers that apply to you.
The hourly amount used for ordinary and overtime calculations.
Keep ordinary and overtime hours inside the same pay period.
Overtime rates
Common rates are time and a half (1.5×) and double time (2×). Add up to three rates and name them to match your workplace or agreement.
A multiplier of 1.5 means rate × 1.5 for that hour—not an extra 1.5× on top.
Enter the hours and full-pay multipliers from the law, award, collective agreement or employment contract that applies to you. This calculator only adds the amounts; it does not decide overtime entitlement.

What this means
Each row covers a separate group of hours in the same pay period. Ordinary earnings are the hourly rate multiplied by ordinary hours.
For each overtime rate, the hourly rate is multiplied by that rate's hours and the full-pay multiplier you enter. A factor of 1.5 means that hour contributes 1.5 times the hourly rate—not another 1.5 times on top.
Ordinary earnings and every active overtime rate are added to produce gross earnings. The average across all hours divides that total by every entered hour. The ordinary-hours equivalent divides it by ordinary hours, showing what the same gross pay would equal per ordinary hour. The calculator does not decide which hours or factors apply to you.
Formula & worked example
ordinary earnings = hourly rate × ordinary hours each overtime rate = hourly rate × that rate's hours × its full-pay multiplier gross earnings = ordinary earnings + all overtime-rate earnings total hours = ordinary hours + all overtime hours average across all hours = gross earnings ÷ total hours (when total hours > 0) equivalent rate over ordinary hours = gross earnings ÷ ordinary hours (when ordinary hours > 0)
$25 hourly rate, 40 ordinary hours, 5 time-and-a-half hours and 0 double-time hours
- Ordinary earnings: $25 × 40
- $1,000
- Time and a half: $25 × 5 × 1.5
- $187.50
- Double time: $25 × 0 × 2
- $0
- Gross earnings: $1,000 + $187.50 + $0
- $1,187.50
- Total hours: 40 + 5 + 0
- 45 hours
- Average across all hours: $1,187.50 ÷ 45
- $26.39
- Equivalent rate over ordinary hours: $1,187.50 ÷ 40
- $29.69
For these hours and factors, gross earnings are $1,187.50: an average of $26.39 across all 45 hours, or the equivalent of $29.69 over the 40 ordinary hours. These figures do not determine overtime entitlement.
