What is the overtime pay calculator — weekly & annual overtime earnings?
In short
Under the FLSA, hours worked beyond 40 per week must be paid at 1.5× your regular rate. At $25/hr, overtime pays $37.50/hr. Working 5 extra hours per week adds $187.50/week — about $9,375/year over 50 weeks. Double-time ($50/hr) applies in some states like California for hours over 12 in a day.
The Overtime Pay Calculator computes your overtime rate, weekly overtime earnings, and how much overtime adds to your annual salary. It supports the FLSA standard 1.5× multiplier, double-time (2×), holiday pay (2.5×), or any custom multiplier. Enter your regular hours and overtime hours per week to see a full weekly and annual breakdown.
How to use this calculator
- 1Enter your regular hourly rate.
- 2Set your regular hours per week (typically 40 under FLSA) and your overtime hours per week.
- 3Choose your overtime multiplier: 1.5× (federal standard), 2× (double-time), or a custom rate.
- 4Adjust weeks per year — use 50 to account for 2 weeks off, or 52 for a full calendar year.
- 5Read your overtime rate per hour, weekly totals, and total annual earnings with overtime.
The formula
- OT rate
- — Overtime hourly rate = regular rate × multiplier
- regular pay
- — Regular hours × regular hourly rate
- overtime pay
- — Overtime hours × OT rate
- total weekly pay
- — Regular pay + overtime pay for the week
- multiplier
- — 1.5 (FLSA), 2.0 (double-time), or custom
Worked example
The scenario
A warehouse worker earns $20/hr, works 40 regular hours and 8 overtime hours per week for 48 weeks a year (FLSA 1.5×).
The result
OT rate = $20 × 1.5 = $30/hr. Regular weekly pay = 40 × $20 = $800. Overtime weekly pay = 8 × $30 = $240. Total weekly = $1,040. Annual regular = $800 × 48 = $38,400. Annual overtime = $240 × 48 = $11,520. Total annual = $49,920.
Common use cases
- Calculate how much a consistent overtime schedule adds to your annual take-home pay.
- Compare job offers where one has guaranteed overtime vs. a higher base salary with no OT.
- Verify your paycheck when your employer switches to a different overtime multiplier.
- Determine whether to work extra hours based on your net overtime rate after taxes.
Limitations & assumptions
- Shows gross pay only — federal/state income tax and FICA reduce actual take-home; use the Paycheck Calculator for net pay.
- FLSA overtime is triggered at 40 hours/week; some states (California, Alaska) also mandate daily overtime (over 8 hours/day) — this calculator uses weekly hours only.
- Does not model fluctuating workweek methods where a fixed salary covers variable hours.
- Premium pay for holidays or weekends is not mandated by federal law — enter your actual multiplier.
