Overtime Pay in Singapore: MOM Rules & Calculation Guide
Overtime Pay in Singapore: A Practical Guide for SMEs (2026) Getting overtime right is one of the trickiest parts of payroll for SMEs in Singapore — get it wrong, and you’re looking at disputes with employees, compliance risks with Ministry of Manpower, and sometimes penalties that could’ve easily been avoided. Once you understand what Ministry of Manpower actually requires, though, it’s a lot more straightforward than it seems, and it goes a long way in keeping your team paid fairly and your payroll running smoothly. This guide breaks down Singapore’s overtime rules in plain language, walks through real examples, and shows how SMEs can make the whole process simpler to manage. What Is Overtime Pay in Singapore? Ministry of Manpower (MOM) defines overtime as any work an employee does beyond their normal contractual working hours — meal breaks and rest breaks don’t count toward this. Whether an employee is entitled to overtime pay depends on whether they’re covered under Part IV of the Employment Act. For employees who are covered, employers are required to pay at least 1.5 times the employee’s hourly basic rate for every hour of overtime worked. This payment can’t be delayed — it needs to reach the employee within 14 days of the end of the salary period it relates to. Who Is Eligible for Overtime Pay? Not every employee in Singapore qualifies for statutory overtime.Employees covered under Part IV of the Employment Act include: Non-workmen earning a monthly basic salary of $2,600 or less Workmen earning a monthly basic salary of $4,500 or less Managers and executives are generally not covered under Part IV of the Employment Act. Example: Administrative Executive Sarah works as an administrative assistant and earns a monthly basic salary of $2,400.Eligible for overtime pay because her salary falls within the non-workman threshold.Example: Operations ManagerJames earns $4,800 monthly and performs managerial duties.Generally not eligible for statutory overtime under Part IV. His employment terms will be governed by his employment contract. What Are the Normal Working Hours? MOM specifies that contractual working hours generally cannot exceed: Work Schedule Maximum Contractual Hours 5 days or fewer per week Up to 9 hours per day or 44 hours per week More than 5 days per week Up to 8 hours per day or 44 hours per week For alternative work arrangements, different averaging rules may apply.Example: When Does Overtime Start?ScenarioAn employee works: 8 hours per day, Monday to Friday,Total contractual hours: 40 per week, One day, the employee works until 8 PM instead of 6 PM.ResultNormal hours: 8, Additional hours worked: 2, Overtime claimable: 2 hours, Since the employee worked beyond contractual hours, the additional 2 hours are considered overtime. How Is Overtime Pay Calculated? MOM Overtime Formula Overtime Pay = Hourly Basic Rate of Pay × 1.5 × Overtime Hours Worked For monthly-rated employees, the hourly basic rate is calculated using: Hourly Basic Rate = (12 × Monthly Basic Salary) ÷ (52 × 44) Example: Overtime Pay Calculation Employee Details Monthly Basic Salary: S$2,400 Overtime Hours Worked: 10 hours Step 1: Calculate the Hourly Basic Rate Formula: Hourly Basic Rate = (12 × Monthly Basic Salary) ÷ (52 × 44) Calculation: = (12 × S$2,400) ÷ (52 × 44) = S$12.59 per hour Step 2: Calculate the Overtime Pay Formula: Overtime Pay = Hourly Basic Rate × 1.5 × Overtime Hours Worked Calculation: = S$12.59 × 1.5 × 10 = S$188.85 Result Monthly Basic Salary: S$2,400 Overtime Hours Worked: 10 hours Hourly Basic Rate: S$12.59 Total Overtime Pay: S$188.85 The employee should receive S$188.85 in overtime pay for 10 hours of overtime work, based on the Ministry of Manpower (MOM) overtime calculation formula. Note: Overtime pay is calculated using the employee’s basic salary only. Allowances, bonuses, commissions, incentives, and other variable payments are generally not included when calculating the hourly basic rate.

Overtime Rate Cap Employers Should Know For eligible non-workmen, overtime calculations are capped at a salary level of $2,600, equivalent to an hourly overtime calculation cap of $13.60 per hour.ExampleAn employee earns $2,600 monthly and works 2 overtime hours.Calculation:1 $13.60 × 1.5 × 22 = $40.80This is the example provided by MOM. Maximum Overtime Hours Allowed Employers should monitor overtime carefully.MOM limits eligible employees to: Maximum 72 overtime hours per month Employers requiring additional overtime must apply for an exemption. Example: Retail SME During Peak SeasonA retail business experiences high sales during year-end promotions. Employee OT accumulated: 68 hours Additional OT requested: 10 hours Without an approved exemption, the employer risks exceeding the statutory monthly OT limit. SMEs should monitor overtime proactively to avoid compliance issues. Maximum Daily Working Hours Employees generally cannot work more than 12 hours per day. Exceptions may apply for emergencies, urgent machinery repairs, national security requirements, unforeseen interruptions, or approved overtime exemptions. Example: Manufacturing BreakdownA production machine unexpectedly fails and urgent repair work is needed to fulfil customer orders.The employer may require employees to work beyond normal hours due to unforeseen operational interruptions, subject to MOM requirements. Understanding Rest Day Rules Employers must provide: One rest day every week A full day from midnight to midnight Maximum gap of 12 days between rest days Shift workers may have a continuous 30-hour rest period instead. How Is Pay Calculated for Work on a Rest Day? MOM differentiates between:Work requested by the employer, Work requested by the employeeHours worked beyond normal daily working hours. Example: Employer Requests Work on a Rest DayEmployee’s normal workday: 8 hours Employee
