How to Calculate Overtime Pay (MOM) in Singapore: A Step-by-Step Guide
Uses the Ministry of Manpower formula to work out the hourly basic rate and overtime pay for employees covered by Part IV of the Employment Act.
In Singapore, payslip maths decides how much you can save, invest and spend, and CPF takes a sizeable share before the money reaches your bank account. Knowing the numbers in advance makes salary negotiations, job switches and budgeting far less of a guess.
What you need
- Monthly basic salary (S$)
- Overtime hours worked
Step by step
- Enter the monthly basic salary (S$).
- Enter the overtime hours worked.
- The results update as you type, or press Calculate.
- Read the hourly basic rate first, then the supporting figures below it.
The formula
Hourly basic rate = (12 × monthly basic salary) ÷ (52 × 44). Overtime pay = 1.5 × hourly rate × overtime hours.
Worked example
For example, with these inputs:
- Monthly basic salary (S$): 2,400
- Overtime hours worked: 20
the calculator returns:
- Hourly basic rate: S$12.59
- Overtime rate (1.5×): S$18.88
- Overtime pay: S$377.62
A second example
Now change the inputs to:
- Monthly basic salary (S$): 3,000
- Overtime hours worked: 20
the calculator returns:
- Hourly basic rate: S$15.73
- Overtime rate (1.5×): S$23.60
- Overtime pay: S$472.03
Practical tips
- Overtime eligibility depends on your salary and role under Part IV of the Employment Act, not just your job title.
- Employer CPF is not part of your take-home pay, but it is part of your total compensation, so count it when comparing offers.
- If you change jobs mid-year, the Additional Wage ceiling is calculated across all employers for the calendar year.
- CPF rates drop in steps after age 55, so check which age band applies from the month after your birthday.
Background
CPF distinguishes between ordinary wages, which are paid for work in the month such as basic salary and fixed allowances, and additional wages, such as annual bonuses and leave encashment. Ordinary wages are capped at S$8,000 a month from January 2026, while additional wages are capped by an annual ceiling of S$102,000 minus the ordinary wages already subject to CPF in the year.
Payslips must be itemised, showing basic pay, allowances, overtime, deductions and CPF. Comparing a payslip against an independent calculation is the easiest way to catch mistakes, especially in the first month of a new job, after a pay rise, or when you cross an age band.
Contribution rates fall as workers get older, to keep older workers employable while their retirement savings continue to grow. The Government has been raising rates for workers above 55 in stages since 2022, with the latest change in January 2026 and another planned for 2027, so figures for senior workers change more often than for younger employees.
