Overtime Calculator
Overtime math is simple in theory, but small timesheet errors slip through more often than most people realize. This calculator lets you double-check your regular and overtime pay yourself in a few seconds, using the same math your paycheck is supposed to follow.
Enter your hours to see your total pay.
How to use this calculator
- Enter your regular hourly rate.
- Enter your regular hours (usually up to 40/week) and overtime hours separately.
- Choose your overtime multiplier — 1.5× is standard under federal law, some employers or holidays pay 2×.
- Click "Calculate overtime pay" for your total gross pay.
Why it matters
Under the federal Fair Labor Standards Act, most non-exempt hourly employees must be paid at least 1.5× their regular rate for hours worked beyond 40 in a week. Checking the math yourself helps confirm your paycheck is correct.
A worked example
Say you earn $24/hour and worked 40 regular hours plus 6 overtime hours in a week. Regular pay comes to $960, and overtime pay at 1.5× adds $216, for a total of $1,176 gross for the week. If your pay stub shows anything meaningfully lower — after accounting for known deductions — it's worth flagging to payroll, since small timesheet errors are one of the most common sources of underpaid overtime.
Frequently asked questions
Is overtime always 1.5x?
Federal law requires at least 1.5x for eligible employees after 40 hours/week. Some states, union contracts, or holiday policies pay more — check your specific rules.
Am I eligible for overtime?
Most hourly ("non-exempt") employees are eligible. Salaried "exempt" employees often are not, depending on job duties and salary level. This calculator doesn't determine eligibility.
Does this include taxes?
No, this is gross pay before taxes. Use the Paycheck Calculator for an after-tax estimate.
What about a part-time employee working extra hours?
Overtime rules are based on hours worked in a week, not your usual schedule — a part-time employee who crosses 40 hours in a single week is generally still owed overtime on the hours above that.
How do I check if my employer made a mistake?
Run your actual hours and rate through this calculator and compare it directly to your pay stub — a mismatch is worth raising with payroll, since most discrepancies turn out to be simple timesheet errors.
Is overtime calculated daily or weekly?
Federally, it's weekly — anything over 40 hours in a week. A handful of states (including California, Alaska, Colorado, and Nevada) also require daily overtime once you pass a set number of hours in a single day, on top of the weekly rule.
Am I owed time and a half for working a holiday?
Not automatically — federal law doesn't require extra pay just for working a holiday. Many employers offer it anyway as a benefit, so check your specific company policy rather than assuming it's a legal requirement.
Time-and-a-Half Rates
Time and a half means 1.5 times your regular hourly rate. Here is the overtime rate at common hourly wages, with double time for comparison:
| Regular hourly rate | Time and a half (1.5x) | Double time (2x) |
|---|---|---|
| $15.00 | $22.50 | $30.00 |
| $18.00 | $27.00 | $36.00 |
| $20.00 | $30.00 | $40.00 |
| $25.00 | $37.50 | $50.00 |
| $30.00 | $45.00 | $60.00 |
| $40.00 | $60.00 | $80.00 |
Overtime Pay by Hours Worked
This chart shows the overtime pay for the hours above 40 in a week at 1.5x. The last column shows total gross pay for a week with 40 regular hours plus 10 overtime hours.
| Hourly rate | 5 overtime hours | 10 overtime hours | 15 overtime hours | 20 overtime hours | Total for 40 + 10 hours |
|---|---|---|---|---|---|
| $15.00 | $112.50 | $225.00 | $337.50 | $450.00 | $825.00 |
| $18.00 | $135.00 | $270.00 | $405.00 | $540.00 | $990.00 |
| $20.00 | $150.00 | $300.00 | $450.00 | $600.00 | $1,100.00 |
| $25.00 | $187.50 | $375.00 | $562.50 | $750.00 | $1,375.00 |
| $30.00 | $225.00 | $450.00 | $675.00 | $900.00 | $1,650.00 |
How Overtime Pay Is Calculated
Multiply your regular hourly rate by 1.5, then multiply by the overtime hours worked. For $24 an hour and 6 overtime hours, that is $24 × 1.5 × 6 = $216, added to your regular pay. Under the Fair Labor Standards Act, covered non-exempt employees must receive at least time and a half for hours over 40 in a workweek. Some states also require daily overtime. You can read the federal rules on the U.S. Department of Labor page for overtime pay.
