How to Calculate Salary with Overtime
Overtime pay is one of the most important — and most often miscalculated — components of a worker's paycheck. When extra hours are worked beyond a standard schedule, those hours are typically compensated at a higher rate: 1.5× regular pay (time-and-a-half) is the US federal minimum for non-exempt employees; 2× (double-time) is common for Sundays, holidays, or extended overtime; many countries and contracts use their own multipliers. This calculator handles any multiplier, any currency, and any time period.
The tool is split into two clean sections: Regular Worktime (your base hourly pay and normal hours) and Overtime (the multiplier, derived overtime hourly rate, and extra hours worked). It computes each side's totals separately, then adds them for the combined gross pay.
💡 Don't Forget: Overtime Rate ≠ Just the Multiplier
Overtime pay is Regular Hourly × Multiplier — not regular hourly plus the multiplier. A 1.5× multiplier on $20/hr gives a $30/hr overtime rate (not $21.50). This is the most common mistake in manual overtime math.
Supports 30+ currencies and flexible time periods (day / week / month / year), so whether you're checking a daily contractor rate or a monthly salary with occasional overtime, the math works. Pay period labels update dynamically in the results panel so totals always read clearly.

The Overtime Pay Formula
Overtime Hourly = Regular Hourly × Multiplier. For a $20/hr regular rate at 1.5× (time-and-a-half): overtime rate = 20 × 1.5 = $30/hr. At 2× (double-time): 20 × 2 = $40/hr. Note: this is the total overtime rate, not the bonus on top.
Total Regular = Regular Hourly × Regular Hours. At $20/hr for 160 hrs/mo (standard full-time): 20 × 160 = $3,200/mo. The "period" in the tool (day/week/month/year) is just a label — the math is rate × hours regardless.
Total Overtime = Overtime Hourly × Overtime Hours. At the same $20/hr regular rate with 1.5× multiplier and 10 overtime hours: total overtime = 30 × 10 = $300. Add this to the regular total for the combined paycheck.
Combined = Total Regular + Total Overtime. Full example: $3,200 + $300 = $3,500/mo gross. This is what appears on the pay stub before taxes, benefits, and other deductions.
Example: US Time-and-a-Half Overtime
Under the US Fair Labor Standards Act (FLSA), non-exempt employees must be paid at 1.5× their regular rate for any hours worked beyond 40 per week. Here's how that plays out:
| Scenario | Regular Pay (40 hrs × $20) | Overtime Hours | Overtime Pay (1.5×) | Weekly Total |
|---|---|---|---|---|
| No overtime | $800 | 0 hrs | $0 | $800 |
| Light OT | $800 | 5 hrs | $150 | $950 |
| Moderate OT | $800 | 10 hrs | $300 | $1,100 |
| Heavy OT | $800 | 20 hrs | $600 | $1,400 |
| Extreme OT | $800 | 40 hrs (80-hr week) | $1,200 | $2,000 |
Notice that at heavy overtime, the overtime portion can match or exceed the regular portion. This is why it's crucial to track OT hours carefully and verify that employers correctly apply the 1.5× multiplier — a surprisingly common payroll error.

Key Takeaways
Overtime pay is often the difference between a modest paycheck and a substantial one for hourly workers. Getting the math right — multiplying the regular rate by the overtime multiplier, then applying that rate to overtime hours — seems simple but is one of the most common payroll errors. This calculator removes the ambiguity and produces a defensible, auditable breakdown every time.
Key rule to remember: Overtime Hourly = Regular × Multiplier, not regular + multiplier. At 1.5×, you earn your regular rate plus half again — the whole block, not just the extra. For 10 overtime hours at $20/hr regular, that's $300 total, not $100 of "extra" on top of the regular $200.

Frequently Asked Questions
How do I calculate overtime pay?
Multiply your regular hourly rate by the overtime multiplier (commonly 1.5) to get the overtime hourly rate. Then multiply the overtime rate by the number of overtime hours worked. For a $20/hr job with 10 overtime hours at 1.5×: Overtime rate = 20 × 1.5 = $30/hr. Total overtime pay = 30 × 10 = $300.
What is time-and-a-half?
"Time-and-a-half" means 1.5× your regular hourly rate. It's the US federal minimum overtime rate for non-exempt employees working more than 40 hours per week under the Fair Labor Standards Act (FLSA). A $20/hr worker earns $30/hr during time-and-a-half overtime.
What is double-time?
"Double-time" means 2× your regular hourly rate. While not federally required in the US, double-time is common in union contracts, many states (California requires it for >12 hrs/day or >8 hrs on 7th consecutive workday), on Sundays, holidays, and for severe overtime. Some employers voluntarily offer double-time to encourage coverage of undesirable shifts.
When does overtime start?
It depends on the jurisdiction and role type:
- US FLSA: After 40 hours in a workweek for non-exempt employees
- California: After 8 hrs/day OR 40 hrs/week, whichever hits first
- Canada (federal): After 8 hrs/day or 40 hrs/week
- UK: No federal overtime premium requirement, but most employment contracts specify it
- EU Working Time Directive: Caps total weekly hours at 48 (averaged over 17 weeks)
Does overtime apply to salaried employees?
In the US, most salaried employees classified as "exempt" under FLSA (executive, administrative, professional roles meeting duty and salary-level tests) are not entitled to overtime pay. Salaried non-exempt employees, however, must receive overtime for hours beyond 40/week — calculated by dividing salary by expected weekly hours to derive an effective hourly rate. Exemption rules vary by country; always verify with local labor law.
Can I use custom multipliers like 1.25 or 1.75?
Yes — the multiplier field accepts any positive number. Union contracts and some employment agreements specify non-standard multipliers (e.g., 1.25× for shift differential, 1.75× for stand-by, 2.5× for certain holidays). Enter whatever your agreement specifies; the math is the same.
Is overtime taxed differently?
No — overtime is taxed at your normal income tax rate. However, the larger paycheck that includes overtime may push you temporarily into a higher withholding bracket for that pay period, making it look like OT is taxed more. This is reconciled at year-end when actual tax liability is calculated against total annual income.
