How to Calculate OT Pay Singapore

Singapore Overtime Pay Guidelines (MOM)

Understanding how to calculate overtime pay in Singapore according to Ministry of Manpower (MOM) regulations is essential for both employers and employees.

Overtime Rates in Singapore

Type of Work	Rate	Calculation
Weekday Overtime	1.5x hourly rate	Basic hourly rate × 1.5
Rest Day Work	2x hourly rate	Basic hourly rate × 2
Public Holiday Work	2x hourly rate	Basic hourly rate × 2

Who is Entitled to Overtime Pay?

Non-exempt employees: Monthly salary below $2,500
Partially exempt employees: Monthly salary $2,500 - $4,500 (overtime only for work beyond normal hours)
Exempt employees: Monthly salary above $4,500 (not entitled to overtime pay)

How to Calculate Hourly Rate

Formula:

Hourly Rate = Monthly Basic Salary ÷ (Working Days per Month × Working Hours per Day)

Example:

Monthly Salary: $3,000
Working Days: 22 days
Working Hours: 8 hours/day
Hourly Rate = $3,000 ÷ (22 × 8) = $17.05

Overtime Calculation Examples

Example 1: Weekday Overtime

Hourly Rate: $17.05
Overtime Hours: 10 hours
OT Rate: $17.05 × 1.5 = $25.58
Total OT Pay: $25.58 × 10 = $255.80

Example 2: Rest Day Work

Hourly Rate: $17.05
Rest Day Hours: 8 hours
OT Rate: $17.05 × 2 = $34.10
Total OT Pay: $34.10 × 8 = $272.80
