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.

You choose the applicable rules

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.

Gross pay before tax and deductions. This result does not determine legal entitlement.

Included

  • Gross ordinary earnings from the hourly rate and ordinary hours you enter
  • Up to three named overtime-hour groups using your full-pay multipliers
  • Gross total, total hours, average across all hours and equivalent rate over ordinary hours

Not included

  • Whether any hour qualifies for overtime or which multiplier legally applies
  • Tax, deductions, take-home pay, bonuses, commissions, allowances and time off in lieu
  • Minimum-wage, award, collective-agreement, employment-contract or payroll compliance

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.

Common questions

Does 1.5 always apply after 40 hours?
No. Forty hours and 1.5× are familiar examples in some rules, but coverage, thresholds, base rates and exceptions vary. Enter the hours and full-pay factor supplied by the law, award, collective agreement or contract that applies to you.
What does full-pay multiplier mean?
It is the complete factor applied to the hourly rate for that tier. At 1.5, a $20 hourly rate produces $30 for each entered tier hour. It does not add a further $30 on top.
What are the additional overtime rates for?
Use them when your rule separates hours at different factors—for example time and a half, double time, or a distinct weekend or public-holiday rate. Add only the rates you need, up to three.
Which pay period should I use?
Use any one period, but keep every hour in the same period. The calculator does not convert weekly, fortnightly or monthly hours.
Are tax and take-home pay included?
No. The result is gross pay before tax, deductions and other payroll adjustments. It also excludes bonuses, commissions, shift differentials and allowances unless you have already included them in the hourly rate.
