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 the employee’s normal work schedule so the calculator can count the working days in that month.
MOM no-pay leave calculation
A monthly-rated full-time employee who takes no-pay leave has an incomplete month of work. MOM calculates the payable salary using the monthly gross rate of pay divided by the total number of working days in that month, multiplied by days actually worked.
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 illustrate the MOM incomplete-month approach. The exact amount changes with the number of scheduled working days in the relevant month.
| Scenario | Monthly salary | Example calculation | Estimated deduction |
|---|---|---|---|
| 1 unpaid day in a 23-working-day month | S$4,000 | S$4,000 ÷ 23 × 1 day | About S$173.91 |
| 3 unpaid days in a 23-working-day month | S$4,000 | S$4,000 ÷ 23 × 3 days | About S$521.74 |
| 2 unpaid days in a 22-working-day month | S$4,000 | S$4,000 ÷ 22 × 2 days | About S$363.64 |
| Half-day unpaid leave in a 23-working-day month | S$4,000 | S$4,000 ÷ 23 × 0.5 day | About S$86.96 |
Why the number of working days matters
For a monthly-rated full-time employee on no-pay leave, MOM treats the month as an incomplete month of work. The denominator is the total number of working days in that month under the employee’s normal work schedule. Rest days and non-working days are excluded, while public holidays that fall on scheduled working days are included.
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 | For monthly-rated full-time employees, check the MOM incomplete-month rule and the employee’s actual work schedule; company policy should not override statutory minimum requirements. |
| CPF | CPF is not calculated here. CPF may be based on the actual wages payable after deduction. |
| Allowances | Only include allowances that form part of the MOM monthly gross rate of pay. MOM excludes items such as travel, food and housing allowances, overtime, bonuses and AWS from this gross-rate definition. |
| Public holidays | Public holidays that fall on scheduled working days remain in the working-day count for the MOM incomplete-month formula. |

What is unpaid leave?
Unpaid leave, also called no-pay leave, is leave where the employee is not paid for the leave period. The salary for the month may be reduced based on the number of unpaid days.
How do I calculate unpaid leave deduction in Singapore?
For a monthly-rated full-time employee, use the monthly gross rate divided by the total working days in that month, then apply the number of unpaid working days (or equivalently calculate salary for days actually worked).
Should unpaid leave be deducted based on calendar days or working days?
For the MOM statutory incomplete-month calculation, use the employee’s working days in the relevant month. A calendar-day or fixed 26-day shortcut should not replace that formula.
Can unpaid leave be half day?
Yes, if your employer allows half-day unpaid leave. You can enter 0.5 day in this calculator.
Does unpaid leave affect CPF?
This calculator does not calculate CPF. In practice, CPF is usually calculated based on the actual wages payable, so unpaid leave may reduce the wage amount used for CPF calculation.
Does unpaid leave affect annual leave?
It may depend on company policy and the length of unpaid leave. For long periods of unpaid leave, employers may have specific rules on leave accrual.
Is no-pay leave the same as unpaid leave?
In many workplace situations, no-pay leave and unpaid leave mean the same thing: approved leave where salary is not paid for the leave period.
Is this unpaid leave calculator official?
No. SG Salary Tools provides general planning calculators only. For exact payroll treatment, check your employment contract, HR policy or seek professional advice.
