Overtime Pay Calculator
Calculate your overtime pay based on hourly rate, hours worked, and overtime multiplier. Includes double-time calculations.
About this calculator
Federal law under the Fair Labor Standards Act (FLSA) requires covered nonexempt employees to receive overtime pay at not less than 1.5 times their regular rate for hours worked beyond 40 in a workweek -- a rule the U.S. Department of Labor's Wage and Hour Division enforces and describes at dol.gov/agencies/whd/overtime -- this calculator applies that principle directly, but leaves the exact hours and multiplier in your control since not every workweek or jurisdiction works the same way. Regular Pay is Hourly Rate multiplied by Regular Hours/Week, and Overtime Rate is Hourly Rate multiplied by Overtime Multiplier (1.5 by default, the FLSA's standard time-and -a-half). Overtime Pay is that Overtime Rate multiplied by Overtime Hours/Week, and an optional Double Time Hours/Week field -- paid flatly at 2x Hourly Rate -- covers holiday or contractual double-time provisions the base FLSA formula does not include.
Weekly Gross Pay sums all three components, and Bi-Weekly, Monthly, and Annual figures simply scale that weekly total forward assuming the same hours repeat every week. Effective Hourly Rate divides Weekly Gross Pay by total hours worked, showing the blended rate across regular, overtime, and double-time hours combined -- useful for comparing an overtime-heavy week against a straight hourly job. Importantly, this calculator applies whatever Overtime Hours/Week and Overtime Multiplier you enter -- it does not automatically detect a 40-hour threshold or enforce it, so you are responsible for entering hours consistent with your actual employer policy and state law, including states like California that require daily overtime after 8 hours regardless of the weekly total.

How to Use This Calculator
- Enter your Hourly Rate, Regular Hours/Week, and Overtime Hours/Week.
- Set the Overtime Multiplier (defaults to 1.5x for standard time and a half).
- Optionally add Double Time Hours/Week, paid at 2x your hourly rate, under advanced options.
- Review Regular Pay, Overtime Pay, and Weekly Gross Pay, plus Bi-Weekly, Monthly, and Annual projections.
- Use for payroll verification — this calculator applies the multiplier and hours you enter, not an automatic 40-hour threshold, so check your state's rules (e.g., California requires overtime after 8 hours/day).

What each input means
- Hourly Rate
- Your base hourly pay rate before any overtime multiplier.
- Regular Hours/Week
- Standard hours per week paid at your base rate (typically 40).
- Overtime Hours/Week
- Weekly hours beyond regular hours, paid at the overtime rate.
- Overtime Multiplier
- Standard overtime is 1.5x (time and a half).
- Double Time Hours/Week
- Hours paid at 2x rate (holidays, etc.).
How this is calculated
Formula
Overtime Pay = Hourly Rate × Overtime Multiplier × Overtime Hours. Standard overtime is 1.5× for hours over 40/week under FLSA.Worked example, using the default values

Frequently Asked Questions
Does this calculator automatically apply overtime after 40 hours?
No -- you manually split your total hours into Regular Hours/Week and Overtime Hours/Week yourself, and the calculator applies the Overtime Multiplier only to whatever you enter in the Overtime Hours/Week field. This flexibility matters because overtime rules vary: federal FLSA law (29 U.S.C. § 207, enforced by the U.S. Department of Labor's Wage and Hour Division) triggers overtime after 40 hours in a week, but some states like California require daily overtime after 8 hours in a single day regardless of the weekly total.
Why is there a separate Double Time Hours/Week field?
Double time (paid at 2x Hourly Rate) is not required under federal FLSA law, but many employer policies or state rules apply it for holiday work or, in California, for hours worked beyond 12 in a single day. This calculator keeps Double Time Hours/Week separate from Overtime Hours/Week since it's always paid at a fixed 2x rate rather than the adjustable Overtime Multiplier.
How does Effective Hourly Rate differ from Hourly Rate?
Hourly Rate is your base pay rate before any overtime multiplier is applied, while Effective Hourly Rate is Weekly Gross Pay divided by total hours worked across regular, overtime, and double-time combined. Effective Hourly Rate will always be at or above Hourly Rate whenever you work any overtime or double-time hours, since those hours pull the blended average up.
Does raising the Overtime Multiplier always increase Weekly Gross Pay?
Yes, as long as Overtime Hours/Week is greater than zero -- Overtime Pay is Hourly Rate multiplied by Overtime Multiplier multiplied by Overtime Hours/Week, so a higher multiplier directly raises Overtime Pay and therefore Weekly Gross Pay. If Overtime Hours/Week is set to zero, changing the multiplier has no effect since there are no overtime hours for it to apply to.
