How this final salary calculator works
Final salary is usually affected by how many days you worked in your final month, whether you took unpaid leave, whether unused annual leave is encashed, and whether there are other allowances or deductions.
1. Calculate final-month salary
For an incomplete final month, monthly gross rate is divided by the total working days in that month and multiplied by days actually worked.
2. Add salary for days worked
Paid days worked are multiplied by daily salary to estimate your prorated final month salary.
3. Add or deduct adjustments
Unused annual leave encashment uses the gross daily rate. Other contractual payments and valid deductions can then be added or deducted.
Final salary formula
A simple final salary estimate can be calculated using daily salary, paid days worked, unused leave and deductions.
| Item | Formula | Meaning |
|---|---|---|
| Incomplete final-month salary | Monthly gross rate ÷ working days in month × days actually worked | Salary earned for an incomplete final month |
| Gross daily rate | 12 × monthly gross rate ÷ (52 × average working days per week) | Used for salary in lieu of annual leave |
| Leave encashment | Gross daily rate × unused annual leave days | Estimated value of unused annual leave paid out |
| Final salary | Final-month salary + leave encashment + other pay − deductions | Estimated final gross amount before CPF and tax adjustments |
Common final salary examples
These examples show how final salary may change depending on paid days worked and unused annual leave.
S$5,000 salary, 10 of 22 working days
Incomplete final-month salary is about S$2,272.73 using S$5,000 ÷ 22 × 10.
3 days unused annual leave
For a 5-day workweek, the gross daily rate on S$5,000 is about S$230.77, so 3 days are about S$692.31.
Other adjustments
Add contractual amounts that are payable and deduct valid payroll deductions separately; they do not change the incomplete-month denominator.

Frequently Asked Questions
How do I calculate final salary in Singapore?
For an incomplete final month, calculate salary using the MOM incomplete-month formula, then add any unused annual leave encashment based on the gross daily rate and other payable amounts, less valid deductions.
Is final salary based on working days or calendar days?
For a monthly-rated full-time employee with an incomplete final month, MOM uses the total working days in the relevant month. Salary in lieu of annual leave uses the gross rate of pay instead.
Can unused annual leave be paid out when I resign?
Unused annual leave may be encashed depending on the Employment Act, your employment contract and company policy. You should confirm your leave balance and payout treatment with HR.
Does this calculator include CPF?
No. This calculator estimates final gross salary before CPF. Use the CPF Calculator to estimate CPF on salary items.
Can I use this for resignation salary?
Yes. This calculator is designed for employees who resign, leave mid-month or want to estimate their final payslip.
Is this final salary calculator official?
No. It is an independent estimate for planning only. For official employment matters, check MOM guidance or your employer’s HR policy.
