Overtime Pay Calculator (1.5× and 2× Rates)
Calculate gross pay with overtime — regular hours plus time-and-a-half (and optional double-time) on hours over 40 — from your rate and hours. Runs in your browser.
US federal: 40/week.
Time-and-a-half = 1.5.
Subset of hours paid at 2× (some states/contracts).
Overtime pay = OT hours × base rate × multiplier. Under US federal law (FLSA), non-exempt employees earn at least 1.5× their regular rate for hours over 40 in a workweek. Some states (e.g. California) add daily overtime and double-time rules — adjust the threshold and double-time fields accordingly. Overtime is based on the “regular rate,” which includes certain bonuses and differentials. Gross pay, before taxes. Educational; everything runs in your browser.
About this tool
Overtime pay is the higher rate non-exempt employees earn for working beyond a threshold, and this calculator splits a week's hours into regular and overtime portions to compute gross pay. Under the US Fair Labor Standards Act (FLSA), covered employees must be paid at least time-and-a-half — 1.5 times their regular rate — for hours worked over 40 in a workweek, and this tool defaults to that 40-hour threshold and 1.5× multiplier. It also supports double-time (2×), which federal law doesn't require but some states and union contracts do: California, for example, mandates overtime after 8 hours in a day and double-time after 12 hours in a day or beyond 8 on the seventh consecutive workday. You enter total hours, base rate, the overtime threshold, the overtime multiplier, and optionally a number of double-time hours, and the tool breaks out regular pay, overtime pay, and double-time pay into a gross total. A subtle but important point reflected in the design: overtime is legally calculated on the 'regular rate of pay,' which isn't always just the base wage — it includes most non-discretionary bonuses, shift differentials, and commissions averaged into an hourly figure, so a worker who earns a shift differential has a higher overtime rate than their base alone. The threshold is also weekly under federal law (not daily), so 9 hours one day and 7 the next is no overtime federally even though one day exceeded 8 — unless a state's daily rule applies, which is why the threshold is editable. Exempt salaried employees (meeting the FLSA duties and salary tests) generally don't receive overtime at all. The result is gross pay before taxes and withholding. Use it to check a paycheck or estimate earnings for an overtime week. Everything runs in your browser; nothing is uploaded.
How to use it
- Enter total hours worked in the week and your base hourly rate.
- Set the overtime threshold (40 under federal law) and the OT multiplier (1.5 for time-and-a-half).
- If applicable, enter double-time hours and their multiplier.
- Read the gross pay broken into regular, overtime, and double-time.
Frequently asked questions
- How is overtime pay calculated?
- Overtime pay = overtime hours × base rate × multiplier. Hours over the threshold (40/week federally) are paid at 1.5×. Total gross = regular hours × rate + overtime pay (+ any double-time).
- When does overtime apply?
- Under US federal law (FLSA), non-exempt employees earn overtime for hours over 40 in a workweek. Some states add daily overtime (e.g. over 8 hours/day in California). Exempt salaried employees generally do not get overtime.
- What is double-time?
- Pay at 2× the regular rate. Federal law does not require it, but some states and contracts do — California, for instance, requires double-time after 12 hours in a day. Enter those hours in the double-time field.
- Is overtime based on my base wage only?
- Not necessarily. Overtime uses the "regular rate of pay," which includes most non-discretionary bonuses, commissions, and shift differentials averaged in — so the OT rate can be higher than 1.5× the base wage alone.
- Is the threshold daily or weekly?
- Federally it is weekly (over 40 hours). Working 9 hours one day is not federal overtime if the week stays under 40. Daily overtime exists only in certain states — adjust the threshold for those rules.
- Is the result before or after taxes?
- Before. The figure is gross pay; taxes and withholdings are deducted separately.
