Pro-Rated Salary in Singapore: Your Questions Answered
These are the questions people ask most often about pro-rated salary. Each answer is short; follow the links for the full detail.
What does a pro-rated salary calculation tell me?
Calculates salary for an incomplete month, such as when you join or leave mid-month.
What is the formula?
Pro-rated salary = monthly salary × days worked ÷ working days in that month.
What do I need to enter?
Monthly salary (S$), Days worked, Working days in the month.
Are these figures exact?
They follow the published CPF and MOM formulas, but your employer's payroll may round slightly differently or include allowances in a different way. Your payslip is the final reference.
Can you show an example?
For example, with these inputs:
- Monthly salary (S$): 4,000
- Days worked: 12
- Working days in the month: 22
the calculator returns:
- Pro-rated salary: S$2,181.82
- Deduction vs full month: S$1,818.18
Any tips?
- Employer CPF is not part of your take-home pay, but it is part of your total compensation, so count it when comparing offers.
- First- and second-year PRs contribute at graduated rates unless they opt in to full rates, so their figures will be lower.
- Keep a copy of your payslips: MOM requires employers to issue itemised payslips, which makes checking deductions easy.
Background
The Employment Act sets out how hourly and daily rates are calculated for overtime, public holiday work and salary deductions. These formulas use the monthly basic rate of pay rather than gross salary, which is why the numbers can look lower than a simple division of your salary by hours worked.
The Central Provident Fund is Singapore's mandatory savings scheme for citizens and permanent residents. Contributions are shared between employee and employer and flow into the Ordinary Account for housing, education and investment, the Special Account for retirement, and MediSave for healthcare. Because the money is locked up for specific purposes, many people underestimate how much of their total pay it represents.
Total compensation in Singapore is more than the number on your offer letter. Employer CPF, variable bonuses, the Annual Wage Supplement (often called the 13th month) and benefits all add value, and comparing offers on take-home pay alone can hide meaningful differences.
