Overtime Calculator
Calculate overtime pay at a single hourly rate — regular pay, overtime pay, and total gross pay.
For most hourly employees, overtime is straightforward: hours worked beyond a set weekly threshold, usually 40, get paid at a higher rate, usually time-and-a-half. This calculator handles that standard case directly — enter your hourly rate and hours worked, and it splits your pay into regular and overtime portions using an adjustable threshold and multiplier, so it also works for states with a different weekly threshold or for modeling double-time. If you work multiple jobs at different pay rates in the same week, the FLSA blended-rate rules apply instead — use the Weighted Overtime Calculator for that case.
Federal FLSA default is 40. Some states set a lower weekly threshold or add daily overtime rules.
1.5 for standard time-and-a-half; use 2.0 to model double-time.

How to Use This Calculator
1. Enter your hourly rate
Your regular, non-overtime hourly pay rate.
2. Enter hours worked this week
Total hours for the week, including any overtime hours.
3. Set the overtime threshold
Defaults to 40 hours/week under federal FLSA rules — adjust if your state sets a lower threshold.
4. Set the overtime multiplier
1.5 for standard time-and-a-half, or 2.0 to model double-time pay.
How It Works
total_pay = (min(hours, threshold) × rate) + (max(0, hours − threshold) × rate × multiplier)46 hours at $22/hour, 40-hour threshold, 1.5x multiplier: (40 × $22) + (6 × $22 × 1.5) = $880 + $198 = $1,078 total.
Frequently Asked Questions
How is overtime pay calculated?
Hours up to the overtime threshold (40/week under federal rules) are paid at the regular rate. Hours beyond the threshold are paid at the regular rate multiplied by the overtime rate, typically 1.5x for time-and-a-half.
Is overtime always 40 hours a week?
40 hours per week is the federal FLSA default, but some states set a lower weekly threshold or add daily overtime rules for very long single shifts. Adjust the threshold field if your state's rules differ from the federal default.
What's the difference between this and the Weighted Overtime Calculator?
This tool assumes one hourly rate for the whole week. The Weighted Overtime Calculator is for the more complex case of an employee working multiple roles at different rates in the same week, which requires a blended "regular rate" calculation under FLSA rather than a simple multiplier.
Common Mistakes
❌ Applying overtime to a daily total instead of the weekly total
Federal FLSA overtime is based on total hours in a workweek, not hours in a single day. Some states (California is the best-known example) add daily overtime rules on top — check your specific state's rules if you're working long single shifts.
❌ Using this for an employee with multiple pay rates in one week
If someone works different roles at different hourly rates within the same week, federal rules require a weighted average "regular rate" calculation, not a simple single-rate overtime split. Use the Weighted Overtime Calculator for that case instead.
❌ Forgetting that salaried non-exempt employees can also owe overtime
Overtime eligibility depends on exemption status under FLSA, not just whether someone is paid hourly or salaried. A misclassified salaried employee can still be legally owed overtime pay.
