Figure out your total pay including regular hours, overtime (1.5x), and double-time (2x) hours. See your effective hourly rate and projected weekly, monthly, and annual earnings.
Overtime pay is one of the strongest features of U.S. labor law for hourly workers. The Fair Labor Standards Act (FLSA), enacted in 1938, requires that non-exempt employees be paid at least 1.5 times their regular hourly rate for any hours worked beyond 40 in a workweek. This "time and a half" premium creates a meaningful economic incentive — a worker earning $25/hour effectively earns $37.50 per overtime hour, and an extra 10 hours of overtime per week can add hundreds of dollars to a paycheck.
Some states go beyond the federal floor. California requires daily overtime (1.5x for hours over 8 in a day, 2x for hours over 12), Saturday/Sunday premiums in certain industries, and seventh-consecutive-day double time. Several other states have daily overtime rules, weekly thresholds below 40 for specific industries (e.g., 5-day, 35-hour weeks for some healthcare workers), or higher premiums for collective bargaining agreements.
This calculator computes total weekly gross pay across regular, overtime (1.5x), and double-time (2x) hours, then extrapolates to monthly and annual figures. Use it to understand a paycheck, plan around expected overtime, or evaluate whether overtime opportunities are worth the marginal effort and tax cost. The output is gross — take-home pay after federal, state, and FICA tax is typically 65–80% of gross for most middle-income earners.
Hourly rate: $25. 40 regular hours + 10 OT hours per week. Regular pay: $25 × 40 = $1,000 OT pay: $25 × 1.5 × 10 = $375 Weekly total: $1,375 Annual (52 weeks): $71,500 Effective hourly: $27.50/hour The 25% increase in hours (40 to 50) produces a 37.5% increase in pay ($1,000 to $1,375) because of the 1.5x premium. Overtime is materially valuable when consistent.
Hourly rate: $30. Working a 16-hour day in California (rare but instructive). Hours 1–8: regular pay = $30 × 8 = $240 Hours 9–12: 1.5x overtime = $30 × 1.5 × 4 = $180 Hours 13–16: 2x double-time = $30 × 2 × 4 = $240 Daily total for 16 hours: $660 (effective $41.25/hour for the day) The same 16 hours at flat $30 would be $480 — California's daily OT plus DT structure produces $180 in additional premium. State labor laws can dramatically change pay outcomes.
$22/hour, 40 regular + 25 OT hours/week (heavy OT pattern). Weekly: $22 × 40 + $22 × 1.5 × 25 = $880 + $825 = $1,705 Annual: $1,705 × 52 = $88,660 Without OT (just 40 hours): $880 × 52 = $45,760. Probably 12% federal marginal bracket. With OT: $88,660. Probably 22% federal marginal bracket. The bracket jump increases the marginal tax on each OT hour. Hours 1–12 OT might be taxed at 12% federal; hours 13–25 may push into 22% federal. Take-home grows with OT but slightly less than gross suggests because of the bracket creep.
Use this calculator at any decision point involving overtime: deciding whether to accept extra hours, projecting annual income with planned overtime, comparing job offers where one has higher base pay vs. overtime opportunity, or simply understanding what a complex paycheck should look like.
For seasonal workers, contractors, and shift workers, the calculator is most useful for projecting annual gross when overtime varies week to week. Average your typical weekly OT hours across the past 6–12 months and use that as the projection input — more realistic than assuming consistent peak weeks.
Pair this with the salary-to-hourly calculator (the inverse direction — given annual salary, compute the equivalent hourly rate), the hourly-to-salary calculator (to compare hourly + OT positions against salaried alternatives), the income-tax-estimator (for after-tax calculations), and the payroll-tax calculator (for FICA and other withholdings on OT pay).
A common workplace dynamic worth knowing: in many industries, overtime is the difference between "decent income" and "good income" — especially for skilled trades, healthcare technicians, manufacturing, public safety, and union jobs. Workers who can sustain 10–15 hours of regular weekly overtime often earn 25–40% more than their straight-time-only counterparts. But chronic high overtime carries real costs: sleep debt, family time costs, accident risk increase, and long-term health impacts. Worth measuring not just the dollar value but the time cost.
An evolving area: federal salary threshold for overtime exemption. As of 2025, salaried employees earning below $58,656/year ($35,568 was the prior 2019 threshold; multiple revisions and court challenges have occurred) are non-exempt and must receive overtime regardless of duties. This threshold has been in legal flux — check current DOL guidance for the latest rule before assuming a salaried role is exempt.
