How to Calculate Pro-Rated Annual Leave in Singapore: A Step-by-Step Guide
Calculates leave earned for part of a year. MOM rounds fractions below half a day down and half a day or more up to a full day.
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
- Full-year leave entitlement (days)
- Completed months of service this year
Step by step
- Enter the full-year leave entitlement (days).
- Enter the completed months of service this year.
- The results update as you type, or press Calculate.
- Read the leave earned first, then the supporting figures below it.
The formula
Pro-rated leave = (completed months ÷ 12) × full-year entitlement.
Worked example
For example, with these inputs:
- Full-year leave entitlement (days): 14
- Completed months of service this year: 7
the calculator returns:
- Leave earned: 8 days
- Exact pro-rated value: 8.1667 days
A second example
Now change the inputs to:
- Full-year leave entitlement (days): 17.5
- Completed months of service this year: 7
the calculator returns:
- Leave earned: 10 days
- Exact pro-rated value: 10.2083 days
Practical tips
- CPF rates drop in steps after age 55, so check which age band applies from the month after your birthday.
- Employer CPF is not part of your take-home pay, but it is part of your total compensation, so count it when comparing offers.
- Remember the S$8,000 monthly Ordinary Wage ceiling from January 2026: salary above it does not attract CPF.
- If you change jobs mid-year, the Additional Wage ceiling is calculated across all employers for the calendar year.
Background
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.
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.
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.
