How this unpaid leave calculator works
This calculator estimates how much salary may be deducted when an employee takes unpaid leave, no-pay leave or has unpaid absence during the salary month.
Use your monthly basic salary. You may also add fixed monthly allowance if needed.
Input the number of unpaid leave days, including half days if applicable.
Select calendar days, working days or fixed 26-day basis depending on your payroll method.
Unpaid leave deduction formula
The general idea is to calculate a daily rate first, then multiply it by the number of unpaid leave days.
| Basis | Formula | Common use |
|---|---|---|
| Calendar days | Monthly salary ÷ calendar days in the month × unpaid leave days | Useful when deduction is based on the full calendar month. |
| Working days | Monthly salary ÷ working days in the month × unpaid leave days | Useful when payroll counts only Monday to Friday working days. |
| Fixed 26-day basis | Monthly salary ÷ 26 × unpaid leave days | Commonly used as a simple daily rate salary deduction method. |
When is unpaid leave deduction used?
Unpaid leave deduction is usually used when an employee is not entitled to paid leave for the absence period, or when the employee applies for no-pay leave.
The employee takes approved leave but the leave is not paid by the employer.
The employee is absent without paid leave entitlement or without sufficient leave balance.
Unpaid days may reduce the monthly salary payable for that month.
Unpaid leave examples
These examples show how unpaid leave deduction may change depending on the calculation basis.
| Scenario | Monthly salary | Example calculation | Estimated deduction |
|---|---|---|---|
| 1 day unpaid leave in July 2026 | S$4,000 | S$4,000 ÷ 31 × 1 day | About S$129.03 |
| 3 days unpaid leave using 26-day basis | S$4,000 | S$4,000 ÷ 26 × 3 days | About S$461.54 |
| 2 unpaid working days in a 23-working-day month | S$4,000 | S$4,000 ÷ 23 × 2 days | About S$347.83 |
| Half-day unpaid leave using 26-day basis | S$4,000 | S$4,000 ÷ 26 × 0.5 day | About S$76.92 |
Calendar days vs working days vs 26 days
The unpaid leave deduction can be different depending on which basis your employer uses. This is why two employees with the same salary and same unpaid leave days may see different deductions under different payroll methods.
Divides salary by the number of days in the month, such as 28, 30 or 31 days.
Divides salary by working days in the month. This calculator counts Monday to Friday.
Divides salary by 26. This can produce a higher daily deduction than calendar basis.
Important notes before using the result
This calculator only estimates unpaid leave salary deduction. It does not decide whether unpaid leave should be approved, whether CPF applies, or whether other payroll adjustments are needed.
| Item | What to check |
|---|---|
| Employment contract | Check whether your contract states how no-pay leave or unpaid absence is deducted. |
| HR policy | Some companies use calendar days, some use working days, and some use 26-day basis. |
| CPF | CPF is not calculated here. CPF may be based on the actual wages payable after deduction. |
| Allowances | Some allowances may be deducted together with basic salary, while others may not be affected. |
| Public holidays | This calculator does not separately remove Singapore public holidays from working days. |
