Work Hours Calculator
Enter your start and finish time on a 24-hour clock, your break and days per week.
This result is an estimate only. Double-check important figures before relying on them.
How it is calculated
- Daily hours = (finish − start − break) ÷ 60
- Weekly = daily × days per week
- Monthly = weekly × 52 ÷ 12
For overtime pay, use the overtime calculator.
Worked example
9:00 to 18:00 with a 60 minute break, 5 days a week:
- 8 hours a day, 40 a week, about 173.3 a month
- At RM20 an hour: RM800 a week
Why your number may differ
The average month ignores the actual number of working days. Public holidays and leave are not subtracted.

What if I work overnight?
If the finish time is earlier than the start, the shift is treated as passing midnight.
Does this include overtime?
No. For overtime rates, use the overtime calculator.
