The working

Coverage: a non-workman on S$2,400.00 basic salary is at or under the S$2,600.00 limit, so overtime pay is compulsory under Part 4 (MOM).
Hourly basic rate = (12 × S$2,400.00) ÷ (52 × 44) = S$28,800.00 ÷ 2,288 = S$12.5874 an hour.
Overtime rate = S$12.5874 × 1.5 = S$18.8811 an hour.
Overtime pay = S$18.8811 × 7 hours = S$132.17, worked out from unrounded amounts and rounded once to the nearest cent (the tool’s convention).

Assumes MOM’s rules for a monthly-rated employee covered by Part 4, or a part-time employee. Basic salary leaves out allowances. Rounds once, at the end, to the nearest cent (our convention). Daily-rated, piece-rated, rest-day and public-holiday pay are not covered.

Rates and rules this tool uses

Overtime rate and when to pay it: For overtime work, your employer must pay you at least 1.5 times the hourly basic rate of pay. Payment must be made within 14 days after the last day of the salary period. MOM: hours of work, overtime and rest day, read 3 October 2026 (page says “Last Updated: 24 July 2025”).
Hourly basic rate, monthly-rated employee: (12 x Monthly basic rate of pay) / (52 x 44). MOM: hours of work, overtime and rest day, read 3 October 2026 (page says “Last Updated: 24 July 2025”).
Who can claim overtime: You can claim overtime if you are a non-workman earning a monthly basic salary of $2,600 or less, or a workman earning a monthly basic salary of $4,500 or less. Part 4 of the Employment Act does not cover managers and executives. If you are not covered under Part 4, your terms and conditions of employment will be according to your employment contract. MOM: hours of work, overtime and rest day, read 3 October 2026 (page says “Last Updated: 24 July 2025”).
What counts as basic salary: Basic salary excludes payment of overtime, bonus, annual wage supplement, productivity incentive payment, reimbursement for special expenses and all allowances. MOM: who is covered by the Employment Act, read 3 October 2026 (page says “Last Updated: 24 July 2025”).
Overtime rate cap for non-workmen (MOM does not settle this): “The overtime rate payable for non-workmen is capped at the salary level of $2,600, or an hourly rate of $13.60.” MOM’s example: a non-workman earns $2,600 a month and works 2 hours of overtime: $13.60 × 1.5 × 2 hours = $40.80. Our arithmetic: MOM’s formula gives $13.64 an hour at $2,600 ($40.91 for the same two hours), and the page does not explain the difference or say how a cap applies to a workman, so from about $2,593.07 a month the tool shows a non-workman both figures and a workman none. MOM: hours of work, overtime and rest day, read 3 October 2026 (page says “Last Updated: 24 July 2025”).
Maximum overtime hours: An employee can only work up to 72 overtime hours in a month. Rest day and public holiday work is not counted in the 72 hours, except work beyond the usual daily working hours on those days. MOM: hours of work, overtime and rest day, read 3 October 2026 (page says “Last Updated: 24 July 2025”).
Part-time overtime: Hours that exceed your daily hours but are less than a full-time employee’s normal hours are paid at your hourly basic rate; hours beyond a full-time employee’s normal hours at your hourly basic rate x 1.5. MOM’s example: 4 hours a day, a full-timer on 8, a $5 rate and 9 hours worked gives (4 hours x $5) + (1 hour x $5 x 1.5) = $27.50. MOM: overtime for part-time employees, read 3 October 2026 (page says “Last Updated: 25 July 2025”).
Hourly basic rate, monthly-rated part-time employee: 12 x Monthly basic rate of pay / (52 x No. of hours worked in a week). MOM: hourly and daily pay for part-time employees, read 3 October 2026 (page says “Last Updated: 29 July 2024”).
Who is a part-time employee: One who is under a contract of service to work less than 35 hours a week. MOM: who is a part-time employee, read 3 October 2026 (page says “Last Updated: 29 July 2024”).

Next review: MOM’s hours-of-work, who-is-covered and part-time overtime pages before each payroll run and whenever MOM announces new salary limits; also recheck whether MOM has explained its S$13.60 hourly cap figure. General information, not tax, legal or financial advice.

How is overtime pay worked out in Singapore?

Overtime pay is at least 1.5 times the hourly basic rate for each hour beyond contractual hours, and for a monthly-rated employee the hourly basic rate is (12 × monthly basic salary) ÷ (52 × 44). Both rules are on MOM’s hours-of-work page, which the tool above follows. It also applies MOM’s separate rule for part-time employees and shows each step of the working.

Who can claim overtime pay under the S$2,600 and S$4,500 limits?

The same page says you can claim overtime as a non-workman earning a monthly basic salary of S$2,600 or less, or as a workman earning S$4,500 or less. Generally, a workman’s work involves mainly manual labour. MOM’s coverage page says basic salary leaves out overtime, bonus, annual wage supplement, productivity incentive payment, reimbursement for special expenses and all allowances, and that Part 4 of the Employment Act does not cover all managers or executives. For anyone outside Part 4, terms follow the employment contract.

What does a worked overtime example look like?

Our illustration, not MOM’s: a non-workman earns S$2,400 basic salary plus a S$150 transport allowance and works 7 overtime hours in a month. The allowance is left out.

Hourly basic rate: 12 × S$2,400 = S$28,800, and 52 × 44 = 2,288, so S$28,800 ÷ 2,288 = S$12.5874.
Overtime rate: S$12.5874 × 1.5 = S$18.8811 an hour.
Overtime pay: S$18.8811 × 7 = S$132.1677 (rates shown to four decimals), rounded once, at the end, to S$132.17.

Rounding once is the tool’s convention: MOM’s current pages state no rounding rule, so rounding each rate first can move the total by a few cents.

How does overtime work for a part-time employee?

MOM’s part-time overtime page counts overtime as work beyond the part-time employee’s normal daily hours. Hours beyond those but below a similar full-time employee’s normal hours are paid at the hourly basic rate, and hours beyond the full-time employee’s normal hours at 1.5 times. MOM’s example: a part-timer works 4 hours a day, a full-timer 8, and the hourly basic rate is S$5. For a 9-hour day, overtime pay is (4 hours × S$5) + (1 hour × S$5 × 1.5) = S$27.50, which the tool reproduces. For monthly pay, MOM’s hourly and daily pay page gives (12 × monthly basic) ÷ (52 × hours worked in a week). Our reading: the S$27.50 pays the five hours beyond the 4-hour day, so the tool leaves out pay for contract hours.

What does this calculator not do?

It does not settle MOM’s S$13.60 figure. The hours-of-work page says the overtime rate for non-workmen is capped at the S$2,600 salary level, or S$13.60 an hour, and prints S$13.60 × 1.5 × 2 hours = S$40.80. Its formula gives S$13.64 an hour at S$2,600 and S$40.91 for the same two hours, and the page does not explain the gap. From about S$2,593.07 a month (our arithmetic from S$13.60) a non-workman sees both figures for their hours, each labelled, with “check with MOM”. A workman above that salary gets no figure, because the page names non-workmen only. MOM publishes its own overtime calculator for monthly-rated employees.

It also leaves out daily-rated and piece-rated pay, although MOM prints a formula for each on the same page, and pay for rest days and public holidays. It warns above MOM’s 72 overtime hours a month for employees covered by Part 4 but does not apply exemptions. MOM’s part-time page states no salary limit, so ask MOM about a part-timer near S$2,600 or S$4,500. Our guides cover overtime pay worked examples, public holiday pay and the first-employee checklist.
