Time-and-a-half and double-time tool
Overtime Calculator
Calculate regular, overtime and double-time earnings from total hours or from hours already separated by pay category.
Estimated gross pay
Overtime pay formulas
Total pay = regular pay + overtime pay + double-time pay.
Regular pay = regular rate × regular hoursOvertime pay = regular rate × overtime hours × overtime multiplierDouble-time pay = regular rate × double-time hours × double-time multiplier
The premium above straight time is rate × overtime hours × max(overtime multiplier − 1, 0) plus the equivalent expression for double-time hours. It is already included in total gross pay.
In total-hours mode, regular hours = min(total hours, threshold) and overtime hours = max(total hours − threshold, 0).
Checked examples
| Inputs | Calculation | Result |
|---|---|---|
| $20/hour, 50 total hours, 40-hour threshold, 1.5× overtime | 40×$20 + 10×$20×1.5 | $1,100 total; $100 premium above straight time |
| $25/hour, 35 regular, 8 at 1.5× and 4 at 2× | $875 + $300 + $200 | $1,375 total; $200 premium above straight time |
| $18/hour, 38 total hours, 40-hour threshold | 38×$18 | $684 total; no overtime |
Choosing a method
Use total-hours mode for a simple threshold scenario. Use category mode when a timekeeping or payroll system has already separated regular, overtime and double-time hours. Do not enter the same hours in more than one category.
Important: this calculator performs pay arithmetic; it does not determine whether a worker is exempt, which hours legally count, or whether daily, weekly, seventh-day, collective-agreement or jurisdiction-specific rules apply. Enter the threshold, categories and multipliers that have already been determined for the situation.
Limits and assumptions
- Hourly rate: greater than 0 through 1,000,000.
- Each hours field: 0 through 1,000; total hours in threshold mode must be greater than 0.
- Multipliers: 0.01 through 10 and treated as total rates, not extra premiums.
- At least one category hour must be positive in category mode; total calculated pay cannot exceed 1 billion.
- Currency changes formatting only. Results are gross amounts before taxes and deductions.
Frequently asked questions
What is time-and-a-half?
Time-and-a-half is 1.5 times the regular hourly rate. At $20 per hour, the time-and-a-half rate is $30 per hour.
What is double time?
Double time is 2 times the regular hourly rate. At $20 per hour, the double-time rate is $40 per hour.
Is the premium the same as overtime pay?
No. Overtime pay includes straight-time value plus the premium. For 10 hours at $20 and 1.5×, overtime pay is $300; the premium portion alone is $100.
Does this calculate taxes or the 2026 overtime tax deduction?
No. It calculates gross earnings only and does not determine tax eligibility, withholding or deductions.
