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.
What Is Overtime Pay for $20 an Hour?
Overtime for $20 an hour is $30 an hour at time and a half, or $40 an hour at double time. Here is what that means for a full week:
| Hours Worked at $20/hr | Regular Pay | Overtime Pay (1.5x) | Total Weekly Pay |
|---|---|---|---|
| 42 hours | $800.00 | $60.00 | $860.00 |
| 45 hours | $800.00 | $150.00 | $950.00 |
| 50 hours | $800.00 | $300.00 | $1,100.00 |
| 60 hours | $800.00 | $600.00 | $1,400.00 |
The same pattern works for any wage: multiply your hourly rate by 1.5 to get your overtime rate, then multiply that by your overtime hours. At $15 an hour, overtime is $22.50; at $25, it is $37.50. If your hours change from day to day, total them first with the Work Hours Calculator, which now shows your gross pay too.
Is Overtime Taxed Less in 2026?
Partly. Under the new federal "no tax on overtime" deduction, the extra half of your time and a half pay (the premium) can be subtracted from your taxable income, up to $12,500 a year. At $20 an hour, that is the $10 premium on each $30 overtime hour. Social Security and Medicare still apply. Our guide to no tax on overtime in 2026 shows who qualifies and how much it saves.
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.
Do overtime rules change by state?
Yes. Federal law (the FLSA) requires 1.5 times pay after 40 hours in a workweek, and many states simply follow that rule. A few go further: California pays overtime after 8 hours in a day and double time after 12, while states like Alaska, Nevada, and Colorado have their own daily overtime rules. When state and federal rules differ, the one that pays you more applies.
How do I calculate overtime on a biweekly paycheck?
Overtime is counted per workweek, not per pay period. If you work 45 hours one week and 35 the next, you are owed 5 hours of overtime even though your two-week total is exactly 80 hours. Run the calculator once for each week, then add the two results together.
Do salaried employees get overtime pay?
Some do. Salaried workers are only exempt from overtime if they meet the FLSA duties tests and earn at least the federal salary threshold of $684 per week (some states set a higher threshold). If you are salaried but non-exempt, convert your salary to an hourly rate with our Salary to Hourly Calculator, then use that rate here.
What is overtime pay for $20 an hour?
Overtime pay for $20 an hour is $30 an hour at time and a half (1.5x) or $40 an hour at double time. If you work 45 hours in a week at $20 an hour, you earn $800 in regular pay plus $150 in overtime, for $950 in total.
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.
