How to Use This Overtime Pay Calculator
- Enter your Regular Hourly Rate — your standard pay per hour, before overtime.
- Enter Regular Hours Worked — typically up to 40 for a standard workweek.
- Enter Overtime Hours Worked — any hours beyond your regular schedule.
- Select your Overtime Multiplier — 1.5× (Time and a Half), 2.0× (Double Time), or 1.0× (Straight Time).
- Read your Pay Breakdown — Regular Pay, Overtime Pay, and Total Pay all update instantly.
How to Calculate Overtime Pay (Manual Formula)
Overtime Pay = Hourly Rate × Overtime Multiplier × Overtime Hours
Total Pay = Regular Pay + Overtime Pay
Worked example: Say you earn $20 per hour, worked 40 regular hours, and 5 overtime hours at the standard 1.5× rate.
- Regular Pay: 20 × 40 = $800.00
- Overtime rate: 20 × 1.5 = $30.00/hour
- Overtime Pay: 30 × 5 = $150.00
- Total Pay: 800 + 150 = $950.00
Understanding Overtime Multipliers
- 1.5× (Time and a Half) — the standard rate required under the Fair Labor Standards Act for non-exempt employees working beyond 40 hours in a workweek. At $20/hour, time-and-a-half is $30/hour.
- 2.0× (Double Time) — not required by federal law, but some employers pay double time for holidays, or state law requires it after working very long single-day shifts (California, for example — see below). At $20/hour, double time is $40/hour.
- 1.0× (Straight Time) — some exempt employees or contract workers are paid their standard rate for all hours worked, with no overtime premium at all.
Calculating Overtime Pay in California
Federal law only looks at a 40-hour workweek. California goes further, applying daily overtime rules on top of the weekly one:
- Hours worked beyond 8 in a single day are paid at 1.5×.
- Hours worked beyond 12 in a single day are paid at 2.0× (double time).
Worked example: A $25/hour employee works 13 hours in one day.
- First 8 hours at regular rate: 8 × 25 = $200.00
- Hours 9–12 (4 hours) at 1.5×: 4 × 37.50 = $150.00
- Hour 13 at 2.0×: 1 × 50 = $50.00
- Total for the day: $400.00
This calculator takes one multiplier at a time, so to reproduce a California-style daily split, run it twice and add the results: first with Regular Hours = 8, Overtime Hours = 4, Multiplier = 1.5× (giving $350.00), then again with Regular Hours = 0, Overtime Hours = 1, Multiplier = 2.0× (giving $50.00). Together that's $400.00, matching the manual calculation above.
Overtime rules vary by state, and some states (California included) have additional rules for the 7th consecutive workday. Confirm the exact thresholds that apply to your situation before relying on any calculation for payroll purposes.
Frequently Asked Questions
How is overtime pay calculated on a paycheck?
Multiply your hourly rate by your overtime multiplier to get your overtime rate, then multiply that by the number of overtime hours worked. Add this to your regular pay (hourly rate × regular hours) for your total pay. The calculator above does this instantly.
Does this calculator work for California overtime rules?
Not automatically — it applies one multiplier at a time rather than California's automatic daily 8-hour and 12-hour thresholds. See the California section above for how to run it twice to reproduce a daily split manually.
Is time-and-a-half (1.5×) always the overtime rate?
No. 1.5× is the federal minimum for non-exempt employees under the Fair Labor Standards Act, but some employers pay more (like 2.0× for holidays or long shifts), and some exempt or contract workers aren't owed overtime at all. Check your employer's policy or your state's labor laws for your specific rate.
Is my data saved anywhere?
No. Nothing you enter is saved or sent anywhere — all calculations run locally in your browser and disappear when you refresh or close the page. Use the Print, Email, or Download buttons to save your results before you leave.
Whether you're checking a single week's paycheck or estimating pay for a long shift under California's daily rules, this calculator handles the arithmetic — just apply your state's specific overtime thresholds on top of the federal standard where they exist. If you only need a fast lookup of your 1.5× or 2× rate without a full pay breakdown, our Time and a Half Calculator covers that in one step.
