Overtime Calculator

Calculate your overtime pay based on hours worked, hourly rate, and state. Shows regular pay, time-and-a-half, and double-time earnings.

Overtime pay can add hundreds of dollars to your paycheck if you're working more than 40 hours per week — or more than 8 hours per day in states with daily overtime laws. This calculator shows exactly what you should earn based on your hours worked, your hourly rate, and your state.

Enter your total hours worked this week, your regular hourly rate, and your state. The calculator breaks down your regular pay, overtime pay (hours 41-60 at 1.5x), and double-time pay (hours over 60, or daily thresholds in certain states).

Federal overtime rules (FLSA)

The Fair Labor Standards Act requires overtime pay at 1.5x the regular rate for all hours over 40 per workweek. This applies to most non-exempt hourly employees in the private sector. Exempt employees (salaried professionals, executives, and some administrative staff earning over $684/week) are not entitled to overtime.

California overtime rules

California has the strictest overtime laws in the country: daily overtime (1.5x) kicks in after 8 hours worked in a single day, and double time (2x) applies after 12 hours in a single day. The weekly calculation still applies on top of this — any hours over 40 in a week are overtime regardless of daily amounts.

Frequently Asked Questions

How is overtime pay calculated?

Take the hours worked over 40 in a week, multiply by 1.5 times your regular hourly rate. Example: 44 hours at $15/hr = 40 regular hours ($600) + 4 OT hours ($15 x 1.5 = $22.50 x 4 = $90) = $690 total.

Does my employer have to pay overtime?

If you're a non-exempt employee under FLSA and work over 40 hours in a workweek, yes — your employer must pay 1.5x for those hours. They can discipline you for unauthorized overtime, but they must still pay for it.

What is double time, and when does it apply?

Double time is 2x your regular hourly rate. It applies in California after 12 hours in a single workday. Some employers offer it voluntarily (often on holidays) even if not legally required by state law.

Can my employer avoid overtime by averaging hours across two weeks?

No — FLSA doesn't allow employers to average hours across multiple workweeks. Each workweek stands alone for overtime calculation, even if your employer pays you biweekly.

Are salaried workers entitled to overtime?

Salaried employees earning less than $684/week ($35,568/year) are generally entitled to overtime under FLSA. Those earning more may be exempt depending on their job duties. The 'salary level test' and 'duties test' both must be met for exemption.
