How it works
Overtime is paid at a multiple of the ordinary hourly rate, applied only to hours worked beyond the standard week. The common rate is one and a half times, with double time reserved for rest days and public holidays.
Two premium tiers are supported here because most real schedules have them: a standard overtime rate for extra weekday hours, and a higher one for weekend or holiday work. Each is calculated against the same base hourly rate.
Pay = (regular × rate) + (OT₁ × rate × mult₁) + (OT₂ × rate × mult₂)
- Base rate — ordinary pay for one hour
- Standard hours — the hours in a normal week before overtime begins
- Multiplier — the premium applied to overtime hours — 1.5 is time and a half
Worked example
A 40-hour week at 500 an hour, plus 6 hours at 1.5× and 4 hours at 2×
Inputs
Results
Ten overtime hours — a quarter of the week — added 8,500, which is 43% more than the same hours would have earned at the base rate.
Frequently asked questions
When does overtime start?
That is set by your local law or employment agreement — commonly after 40 hours a week or 8 or 9 hours a day. Enter your standard hours and count anything beyond them as overtime.
How do I find my base hourly rate if I am salaried?
Divide your monthly salary by the contracted hours in a month. A 45-hour week works out to roughly 195 hours a month, though your contract may state the figure to use.
What is the second premium tier for?
Rest days, public holidays and night shifts, which usually attract a higher multiplier than ordinary weekday overtime. Leave it at zero hours if it does not apply.
