Overtime pay calculator for Singapore

Overtime is any work beyond your normal hours of work, not counting breaks. Under the Employment Act it is paid at least 1.5 times your hourly basic rate.

Enter your monthly basic salary, your type of work and your overtime hours to see what your employer owes you.

How it's calculated

Your hourly basic rate is 12 times your monthly basic salary, divided by 52 weeks of 44 hours.
For non-workmen, the hourly rate used for overtime is capped at $13.60.
Overtime pay is the hourly basic rate times 1.5, times the overtime hours.
The rules cover non-workmen earning up to $2,600 and workmen earning up to $4,500 in basic monthly salary.

An example

A non-workman earning $2,600 who works 2 hours of overtime gets $40.80: $13.60 × 1.5 × 2.
