How to Calculate Overtime Hours

Overtime is any time worked beyond the standard weekly threshold agreed upon in an employment contract or set by local labor law. The most common threshold is 40 hours per week, though 44 and 48 hours are used in many Asian and Middle Eastern markets.

To calculate overtime: add up total hours worked across all days in the week. Subtract the threshold. Any positive remainder is overtime. For example: 46 hours total − 40 hour threshold = 6 hours overtime.

Frequently Asked Questions

About overtime calculation

How is overtime calculated?
Overtime is calculated by subtracting the standard weekly threshold from total hours worked. Any hours above the threshold are overtime. E.g. 45 hours worked − 40 hour threshold = 5 hours overtime.
What is the standard overtime threshold?
In most countries, the standard overtime threshold is 40 hours per week. However, this varies — the UK uses 48 hours, India and UAE use 48 hours, and Australia uses 38 hours.
How do I calculate overtime pay?
Multiply overtime hours by the overtime rate (commonly 1.5x the regular hourly rate). E.g. 5 OT hours × (regular rate × 1.5) = overtime pay.
Do all hours above 8 per day count as overtime?
It depends on jurisdiction and contract. Some countries use daily overtime (over 8h/day), others use weekly overtime (over 40h/week). Check your local labor law or employment agreement.
