How the example is figured
Federal rule: hours over 40 in a workweek are overtime at 1.5× (29 U.S.C. § 207). 10 + 10 + 10 + 10 + 5 = 45 hours, so 40 regular + 5 overtime. 40 × $20 = $800, plus 5 × $30 (1.5 × $20) = $150: $950 before taxes.
California rule: hours over 8 in a workday are overtime too (Labor Code § 510). Each 10-hour day has 2 overtime hours, 8 in all, and 4 × 8 + 5 = 37 regular hours. 37 × $20 = $740, plus 8 × $30 = $240: $980. Other states have their own rules; see overtime by state, and check your state’s rules.
This is an estimate for an hourly job, before taxes, not payroll or legal advice. Bonuses can raise the regular rate, and exempt employees may get no overtime. Your pay stub and your employer have the final numbers.
Frequently asked questions
How do I calculate overtime pay?
Multiply the overtime hours by 1.5 × your hourly rate and add your regular pay. 45 hours at $20 under the federal rule: 40 × $20 = $800 and 5 × $30 = $150, so $950 before taxes.
Is overtime after 40 hours a week or after 8 hours a day?
Federal law counts only hours over 40 in a workweek. A few states, such as California, Alaska and Nevada, also count hours over 8 in a day, and Colorado over 12. Check your state’s rules.
Does the calculator save my hours?
No. It runs in your browser and nothing is sent or saved. To keep a time card that adds up overtime by itself, use the Punchwise app for Android.
