Overtime Pay in Singapore
Overtime pay in Singapore is a key employment right for many workers, regulated by the Employment Act. It ensures employees are fairly compensated for work performed beyond their standard contractual hours. The Ministry of Manpower (MOM) sets clear rules on who is eligible, how to calculate the pay, and the limits on overtime work. This calculator helps you determine your exact entitlement based on these official rules.
Who is Entitled to Overtime Pay?
Eligibility is not universal and depends on your salary and job role. The relevant part of the law is Part IV of the Employment Act. It covers two main groups:
- Workmen: Employees doing manual labour, regardless of salary level, are covered for overtime pay.
- Other Employees (Non-Workmen): Employees who are not workmen are covered if they earn a basic monthly salary of $2,600 SGD or less.
Managers and Executives earning more than $4,500 SGD per month are generally not covered by Part IV. This means they are not entitled to statutory overtime pay under the Act. Their right to overtime pay depends entirely on what is written in their employment contract or collective agreement.
How Overtime Pay is Calculated: The Standard Formula
For covered employees working on a normal working day, the calculation follows a strict three-step process:
- Find Your Hourly Basic Rate: This is the foundation. The formula is: (Monthly Basic Salary × 12) / (52 weeks × Contractual Weekly Hours). Your basic salary excludes allowances, bonuses, and overtime itself.
- Apply the Overtime Multiplier: The law sets the overtime rate at 1.5 times your hourly basic rate.
- Multiply by Overtime Hours: Apply this rate to the number of overtime hours worked in a month. By law, overtime hours are capped at a maximum of 72 hours per month.
Example Calculation (Normal Day): Let's say Jane has a basic monthly salary of $2,200 and works 44 hours per week. She worked 10 hours of overtime on regular working days.
First, her hourly rate: ($2,200 × 12) / (52 × 44) = $26,400 / 2,288 = $11.54 per hour.
Her overtime pay is: $11.54 × 1.5 × 10 hours = $173.10.
Overtime Worked on a Rest Day
Payment for work on your scheduled rest day is significantly higher and uses a two-tier system:
- Work up to Normal Daily Hours: If you work any number of hours up to your normal daily working hours on a rest day, you are entitled to twice your daily salary. The daily salary is calculated as your hourly basic rate multiplied by your normal daily hours (typically derived as weekly hours divided by 6 working days).
- Work Beyond Normal Daily Hours: Any hours worked on the same rest day that exceed your normal daily hours are considered overtime. These extra hours are paid at 1.5 times your hourly basic rate.
Example Calculation (Rest Day with Overtime): John earns $1,800 monthly with a 40-hour week (normal daily hours ~6.67 hours). He works 10 hours on his rest day.
Hourly rate: ($1,800 × 12) / (52 × 40) = $10.38.
For the first 6.67 hours (normal day): $10.38 × 2 × 6.67 = $138.47.
For the remaining 3.33 hours (overtime): $10.38 × 1.5 × 3.33 = $51.85.
Total rest day pay: $138.47 + $51.85 = $190.32.
Important Limits and Practical Considerations
The 72-hour monthly cap on overtime is a strict legal limit for your protection. Your employer must pay you within 14 days after the end of the salary period. This calculator assumes a 6-day work week to determine daily hours for rest day pay. If you work a 5-day week, the calculation of your "daily rate" may differ; please consult your contract or MOM for guidance. This tool does not calculate pay for work on public holidays, which involves different rules (like getting an extra day's salary).
Next Steps: Documenting Your Terms
Clarity is the best way to prevent disputes over pay. Whether you are an employer or an employee, ensure that all terms related to overtime are explicitly stated in a written Employment Contract or Letter of Employment Offer. This document should specify the basic salary, normal working hours, the formula for the hourly rate, the applicable overtime rate(s), and how rest day and public holiday work is compensated. Having these details in writing provides a clear reference for both parties and ensures compliance with Singapore's employment laws.
