Overtime Pay Calculator
Calculate overtime pay at time-and-a-half or double time.
What this calculator does
Calculates total pay including overtime, using your regular hourly rate, regular hours, overtime hours, and the applicable overtime multiplier (time-and-a-half or double time).
Who this is for
Hourly employees checking their expected paycheck before payday, anyone deciding whether picking up extra shifts is worth it financially, or employers double-checking a payroll calculation for a non-exempt employee.
How this calculator works
Under US federal law (FLSA), non-exempt employees earn at least 1.5x their regular rate for hours over 40 in a workweek. Some states and union contracts mandate double time in specific situations (e.g. over 12 hours in a day in California).
The formula
Total Pay = (Regular Hours × Regular Rate) + (Overtime Hours × Regular Rate × Overtime Multiplier).
Worked example
A $22/hour employee working 40 regular hours plus 6 overtime hours at time-and-a-half: Regular pay = 40 × $22 = $880. Overtime pay = 6 × $22 × 1.5 = $198. Total = $880 + $198 = $1,078 for the week.

Common mistakes
- Assuming overtime only kicks in above 40 hours/week everywhere. Some states (notably California) also require daily overtime after 8 hours in a single day, regardless of weekly total.
- Miscalculating the regular rate for salaried non-exempt employees. The "regular rate" used for overtime must include most bonuses and commissions, not just base salary divided by hours — this calculator assumes a flat hourly rate for simplicity.
- Assuming all employees qualify. Exempt employees (many salaried professional, executive, and administrative roles meeting specific criteria) aren't entitled to overtime pay under the FLSA.
- Forgetting that overtime pay is still subject to normal tax withholding. Overtime doesn't get taxed at a special higher rate — it's added to your regular income for the pay period and taxed at your normal marginal rate, though it can look like a bigger chunk was withheld due to how payroll systems annualize a single larger paycheck.

Frequently Asked Questions
Is overtime pay taxed at a higher rate?
No — overtime pay is taxed at your normal marginal tax rate, added on top of your regular income for that pay period. It can look like more was withheld because payroll systems sometimes annualize a larger single paycheck, but the actual tax rate applied isn't different or higher.
Does everyone get overtime after 40 hours?
Only non-exempt employees under the FLSA. Many salaried professional, executive, and administrative roles meeting specific criteria are classified as exempt and aren't entitled to overtime pay, regardless of hours worked.
When does double time apply?
Double time isn't required under federal law, but some states (like California) and union contracts mandate it for hours worked beyond a certain daily threshold, such as 12 hours in a single day.
Is overtime calculated weekly or by pay period?
Federal overtime law calculates it based on a fixed 7-day workweek, not a biweekly or monthly pay period — even if you're paid every two weeks, overtime eligibility is determined week by week.
