Overtime calculator
Enter the week's hours as they were worked. Regular hours price at your rate, overtime at 1.5× under the federal weekly frame, and double time — if your employer pays it — at the multiplier you declare.
Result — $25.00/hour — 40 regular + 10 overtime hours — 50 hours in the week

Regular pay — 40 h at $25.00Why this line?Pay for the week's regular hours at the regular rate — the hours that are not paid at a premium. Why this rate: Your declared regular rate — under the FLSA the overtime premium is computed from the employee's regular rate, which is why the rate you enter drives every line below. What changes it: The rate and the number of regular hours you enter. | $1,000.00 | $52,000.00 |
Overtime pay — 10 h at 1.5xWhy this line?Pay for overtime hours at 1.5 times the regular rate. Under the federal Fair Labor Standards Act, hours worked over 40 in a workweek are paid at not less than one and one-half times the regular rate (29 U.S.C. section 207(a); U.S. Department of Labor, Wage and Hour Division). Why this rate: The 1.5x premium is the federal floor for covered employees; some states and many employers pay more, or pay it sooner (daily overtime rules, for example in California) — those are not modeled here. What changes it: The rate and the overtime hours you enter. The split between regular and overtime hours is yours to declare, week by week — this tool does not average hours across weeks, and neither does the FLSA.

Gross pay for the weekWhy this line?The week's gross pay: regular pay + overtime pay + double-time pay, before any tax or deduction. To turn it into take-home pay, run it through the paycheck calculator (the link under the result does that, prefilled). Why this rate: Not a rate — the sum of the week's pay lines above it. What changes it: Every line above it. | $1,375.00 | $71,500.00 |

Methodology, limits and sources
Rates verified on 2026-10-26 (primary sources listed per line).
Model, declared: gross for the week = rate × regular hours + rate × 1.5 × overtime hours + rate × multiplier × double-time hours. The 1.5× premium and the workweek frame are the federal Fair Labor Standards Act rule (29 U.S.C. §207(a); U.S. Department of Labor, Wage and Hour Division — read on 2026-10-26). The double-time multiplier is an employer-policy input, never a federal rule. Limits: state daily-overtime rules are not modeled; the regular rate is the rate you enter (fold-ins such as non-discretionary bonuses are not computed); exempt employees are out of scope. Figures are gross — the take-home step is the paycheck calculator, prefilled from the annualized week.
The federal rule, and its shape
The Fair Labor Standards Act sets the frame: for covered, non-exempt employees, hours worked over 40 in a workweek are paid at not less than one and one-half times the regular rate (29 U.S.C. §207(a)). A workweek is a fixed 168-hour period — it does not have to start on Monday, but it cannot float, and hours cannot be averaged over two weeks to escape the premium. This calculator takes the split as you declare it: regular hours at the rate, overtime hours at 1.5×.
Worked example
At $25/hour with 40 regular hours and 10 overtime hours: regular pay is 40 × $25 = $1,000.00; overtime is 10 × $37.50 = $375.00; the week's gross is $1,375.00, an effective rate of $27.50 an hour over the 50 hours. The same week at straight time would pay $1,250.00 — the premium is worth $125.00. That default is exactly what the calculator shows when the page loads.
Double time: a policy, not a law
No federal law requires double time. Where it exists — union contracts, employer policies, some state rules for very long days — it is a term of the job, not of the FLSA. This calculator therefore treats it as your input: set the double-time hours and the multiplier (2× by default) and they are priced as declared. Set them to zero when your employer has no such policy.
What this model does not do
State daily-overtime rules (for example California's over-8-hours-in-a-day premium) are not modeled — the frame here is the federal weekly one. The FLSA regular rate can also be higher than your base rate when non-discretionary bonuses or shift differentials must be folded into it; this calculator prices the rate you enter. Salaried exempt employees are outside the FLSA overtime rule entirely.

Frequently asked questions
How is overtime pay calculated?
Hours over 40 in a workweek are paid at 1.5 times the regular rate: 10 overtime hours at $25/hour pay 10 × $37.50 = $375. The premium half is what the rule adds — the base rate for those hours is already in the straight-time pay.
Can my employer average my hours over two weeks?
No. The FLSA workweek stands alone: 50 hours in one week and 30 in the next is 10 overtime hours, not two 40-hour weeks — with a narrow exception for certain hospital and residential-care schedules (the “8 and 80” system).
Is double time required by law?
Not by federal law. Double time comes from employer policy, a union contract or, for some very long days, state law. That is why this calculator asks you for the multiplier instead of assuming one.
Who is exempt from overtime?
Employees classified as exempt under the FLSA — most salaried executive, administrative and professional employees who meet the duties and salary tests. Classification depends on the job's duties, not its title.
Is overtime taxed differently?
The withholding on the paycheck is computed like any other wages. One federal provision does apply at filing time: the IRC §225 deduction for qualified overtime compensation (the premium half of FLSA overtime, TY2025–2028, claimed on the return). It is a filing-time deduction, not a withholding rule, and the paycheck calculator does not model it — declared here rather than implied.
