Overtime Pay Calculator
Work out regular pay, overtime hours and overtime pay for a week. The Ontario preset applies the Employment Standards Act rule — time and a half after 44 hours in a work week, no daily overtime. Switch to Custom for another province, a collective agreement or a contract that pays more.
Official sources
Limitations
- Only the Ontario preset is verified. Other provinces have different thresholds (several use 40 h/week and/or 8 h/day); the Custom option is pure arithmetic for the numbers you enter.
- Many Ontario jobs are exempt from overtime or have a higher threshold (managers and supervisors, IT professionals, some construction, road transport, agriculture). Check the exemptions tool linked in the sources.
- If you have two different rates in one week, each overtime hour is paid at 1.5× the rate for the work done in that hour — enter the week in two parts.
Results are estimates for general information and are not legal, tax, payroll or financial advice. Employment contracts, collective agreements and individual circumstances can change what you are owed.
Formula (Ontario preset)
regular hours = min(hours worked, 44) overtime hours = max(hours worked − 44, 0) regular pay = regular hours × rate overtime pay = overtime hours × rate × 1.5 total = regular pay + overtime pay
Worked example — 50 hours at $20/hour
| Regular: 44 h × $20.00 | $880.00 |
| Overtime: 6 h × $30.00 | $180.00 |
| Total gross for the week | $1,060.00 |
The same week banked as lieu time instead would be 6 × 1.5 = 9 hours of paid time off.
What counts as “hours worked”
Time you are required to be at work and available, including paid training and time spent waiting for work, counts. Unpaid eating periods do not. Public holiday pay and vacation pay are not hours worked, so a week with a paid holiday and 40 hours of work has 40 hours for overtime purposes.
Common ways overtime gets underpaid
- Counting per pay period instead of per week. 50 + 38 hours in a biweekly period is 6 overtime hours, not 0 — unless a signed averaging agreement exists.
- Lowering the rate in an overtime week. Not allowed; the regular rate cannot be reduced to offset overtime.
- “You agreed to no overtime.” Employees cannot sign away ESA overtime rights, only agree to averaging or lieu time.
- Paying a salary and assuming it covers everything. Only exempt roles lose overtime; a job title is not an exemption.

- Not sure of your weekly hours? Add them up with the hours calculator or the biweekly timesheet.
- Put the result into the Ontario gross pay checker to compare with your pay stub.
- If you think you have been underpaid, the Ministry of Labour’s Employment Standards Self-Service Tool walks through a claim.
Frequently asked questions
When does overtime start in Ontario?
After 44 hours in a work week, for most employees. Hours are counted per work week as defined by the employer (any fixed 7-day period), not per day and not per pay period. Working four 11-hour days earns no overtime under the ESA; working 45 hours in a week earns one overtime hour.
Is there daily overtime in Ontario?
No. The ESA has no daily overtime threshold. A contract or collective agreement can provide daily overtime, but the Act itself only looks at weekly hours.
What is the Ontario overtime rate?
One and a half times your regular rate (“time and a half”). At $20/hour the overtime rate is $30/hour; at the October 2026 general minimum wage of $17.95 it is $26.93.
Can I get time off instead of overtime pay?
Yes, if you agree in writing or electronically. You bank 1.5 hours of paid time off for each overtime hour, to be taken within 3 months (or 12 months with agreement). If you leave before using it, the overtime must be paid out.
How does an averaging agreement change overtime?
With a written or electronic averaging agreement, hours are averaged over 2 to 4 consecutive weeks and overtime is owed only on the hours above 44 × the number of weeks. For example 50 + 38 hours over two weeks averages 44, so no overtime is owed — without the agreement, the 50-hour week alone would earn 6 overtime hours. Tick “averaging agreement” in the calculator to compare.
I am salaried. Do I get overtime?
Often yes — salary does not remove the right to overtime unless your job is exempt. For a fixed weekly salary covering all hours, the ESA guide divides the weekly salary by 44 to get the regular rate ($950 ÷ 44 = $21.59), then pays 1.5× that for hours over 44. If the salary is for a set number of hours (say 40), the rate is salary ÷ 40, hours 41–44 are paid at the regular rate and hours over 44 at 1.5×.
