Overtime Pay Formula
Total Pay = (Regular Hours × Hourly Rate) + (Overtime Hours × Hourly Rate × Overtime Multiplier)
Inputs used in this calculator
- Hourly Rate: Hourly rate used for this limited estimate; this tool does not calculate a legal regular rate.
- Hours Worked: Total weekly hours on the timecard.
- Regular Hours Threshold: Hours counted at base pay before overtime begins.
- Overtime Multiplier: Premium applied to overtime hours.
How to use the result
- Enter the employee hourly pay rate.
- Enter total hours worked in the week.
- Adjust the regular-hours threshold if your policy differs from 40 hours.
- Review regular pay, overtime pay, and total weekly pay.
Method, scope, and sources
Compact/weekly mode uses max(total included hours − entered weekly threshold, 0) at one entered base rate and multiplier. The advanced worksheet deducts entered breaks from daily hour totals, rounds each daily total by the selected increment, and applies no-premium, simple weekly, simple daily, or simple combined thresholds. Weekly extra overtime is calculated at the scenario level rather than allocated to specific days.
A planning estimate only. Daily and combined modes are not jurisdictional legal rules and do not calculate exemption, compensable time, punch rounding, double time, seventh-day rules, alternative schedules, multiple rates, statutory regular rate, premium stacking, taxes, deductions, or final payroll. Confirm the fixed workweek, policy or agreement, and applicable law outside this tool.
Method status: Partially supported.
Worked example
Hypothetical advanced weekly scenario: entered daily hours less entered breaks produce 44.00 rounded paid hours. With a user-confirmed 40-hour weekly threshold, $20.00 single base rate, and 1.5 multiplier, the scenario prices 40.00 regular hours and 4.00 overtime hours. This does not establish that the worker or hours are legally overtime-eligible.
Sources
- U.S. Department of Labor, Wage and Hour Division — Fact Sheet #23: Overtime Pay Requirements of the FLSA: For covered, nonexempt employees, supports at least 1.5 times the regular rate after 40 hours in a fixed 168-hour workweek; it bars averaging across workweeks and says weekends/holidays do not themselves trigger federal overtime.
- U.S. Department of Labor, Wage and Hour Division / eCFR — 29 CFR § 778.109 — The regular rate is an hourly rate: Defines regular rate as total remuneration subject to exclusions divided by hours actually worked, which limits an entered base hourly wage to a proxy in this scenario.
- California Department of Industrial Relations — Overtime: Shows why a weekly federal-style calculation is not universal: California has general daily overtime after eight hours and double time after 12 hours, subject to exceptions.
Questions about this calculation
Is overtime always 1.5× pay?
Under the U.S. federal FLSA, covered nonexempt employees generally receive at least 1.5 times the regular rate after 40 hours in a fixed workweek. Other laws, exemptions, agreements, and special rules can differ.
Why is the threshold configurable?
The threshold is a user-supplied scenario input. Daily, seventh-day, holiday, and local rules require a separate jurisdiction- or agreement-specific review and are not calculated here.
