MOM Overtime Calculator Singapore (2026)
Calculate your Singapore overtime pay at 1.5× the hourly basic rate, plus rest day and public holiday pay under Part IV of the Employment Act.
How Singapore Overtime Pay Works
Under Part IV of the Employment Act, eligible employees are entitled to overtime pay at at least 1.5× their hourly basic rate. Eligibility depends on category: workmen earning ≤$4,500/mo, or non-workmen earning ≤$2,600/mo. Rest day and public holiday work attract additional lump-sum payments on top of OT for hours beyond the normal working day.

Quick Reference
- • Workman OT cap: $4,500 monthly basic (above this, OT not statutorily required)
- • Non-workman OT cap: $2,600 monthly basic
- • OT rate: 1.5× hourly basic for normal-day, rest day excess, public holiday excess
- • Hourly rate formula: (12 × monthly basic) ÷ (52 × weekly hours)
- • Rest day ≤½ normal day → 1 day pay
- • Rest day >½ but ≤ normal day → 2 days pay
- • Rest day > normal day → 2 days pay + 1.5× OT for excess hours
- • Public holiday: extra day pay + 1.5× OT for hours beyond normal day
- • Statutory monthly OT cap: 72 hours (exceptions need MOM approval)
MOM Overtime Pay, Step by Step
Singapore's overtime rules are set by Part IV of the Employment Act. Only employees below certain salary caps are statutorily entitled to overtime — this prevents the rules from applying to managers and executives who set their own hours.
Worked example 1 — non-workman normal OT: $2,400/mo non-workman works 10 hours of OT. Hourly rate = (12 × 2,400) ÷ (52 × 44) = $12.59. OT pay = 10 × $12.59 × 1.5 = $188.85.
Worked example 2 — rest day work: Same employee works 7 hours on a rest day (more than half but ≤ normal). Pay = 2 × daily rate = 2 × ($12.59 × 8) = $201.44. If they had worked 10 hours: $201.44 + (2h × $12.59 × 1.5) = $201.44 + $37.77 = $239.21.
Worked example 3 — public holiday: Same employee works 8 hours on a PH. Extra day pay = $100.72. If they work 10 hours: $100.72 + 2h × 1.5× hourly = $100.72 + $37.77 = $138.49. PH pay is on top of the employee's normal monthly gross.
The 72-hour monthly OT cap is the statutory ceiling; persistent OT beyond it without MOM approval is an offence. If your employer is asking you to work consistently beyond this cap, that's a red flag worth raising.

Frequently Asked Questions
Who is entitled to overtime pay in Singapore?expand_more
Overtime pay is statutorily required only for employees covered under Part IV of the Employment Act. This means: (1) workmen earning a monthly basic salary of $4,500 or less, or (2) non-workmen earning $2,600 or less. Employees earning above these caps are not legally entitled to overtime pay — though many employers offer it contractually.
What is the overtime rate in Singapore?expand_more
The minimum overtime rate under MOM rules is 1.5× the employee’s hourly basic rate of pay. This applies to: (a) hours worked beyond 8 hours a day or 44 hours a week on normal days, (b) hours worked beyond the normal day on a rest day, and (c) hours worked beyond the normal day on a public holiday.
How is the hourly basic rate calculated?expand_more
For monthly-rated employees, the hourly basic rate = (12 × monthly basic salary) ÷ (52 × weekly working hours). For example, a $2,400 monthly salary at 44 hours/week works out to (12 × 2400) ÷ (52 × 44) = $12.59 per hour. This is the rate used as the basis for all overtime calculations.
How is rest day pay calculated?expand_more
Rest day pay depends on hours worked: (1) less than half the normal day → 1 day’s pay; (2) more than half but up to the normal day → 2 days’ pay; (3) beyond the normal day → 2 days’ pay PLUS 1.5× hourly basic for the excess hours. Rest day pay is in addition to the employee’s usual monthly salary.
How is public holiday pay calculated?expand_more
For employees who work on a public holiday: an extra day’s pay (in addition to the monthly gross), plus overtime at 1.5× hourly basic for hours worked beyond the normal day. As an alternative, employers may grant a day off in lieu instead of the extra day’s pay, by mutual agreement.
What is the maximum overtime allowed in Singapore?expand_more
The statutory monthly cap on overtime hours is 72 hours. Employers wishing to exceed this need to apply to MOM for an overtime exemption. The cap exists to protect employee health and work-life balance — going over it without approval is an offence under the Employment Act.
Are part-time and shift workers entitled to overtime?expand_more
Part-time employees covered under Part IV are entitled to overtime once they exceed the normal hours of a comparable full-time worker (typically 8/day or 44/week). Shift workers in continuous operations may have different averaging rules — typically OT applies once they exceed an average of 44 hours per week over a 3-week cycle.
