Overtime Calculator

This free Overtime Calculator splits your hours at an overtime threshold (40 by default) and pays the extra hours at time and a half (1.5x) or double time (2x). It shows regular pay, overtime pay, and total gross pay instantly in your browser.

Calculate Your Overtime Pay

The Tools Kit’s free Overtime Calculator works out how much you earn for the hours you work beyond your normal schedule. Enter your hourly rate and hours worked, set the overtime threshold, and choose time and a half or double time to see your regular pay, overtime pay, and total gross pay side by side. Everything is calculated instantly in your browser, with no signup.

Overtime pay = (hours worked − threshold) × hourly rate × multiplier. At $22.50 an hour for 46 hours, 6 overtime hours at time and a half add $202.50 to $900.00 of regular pay, for $1,102.50 in total. If you are not sure how many hours you worked, total your shifts first with the time card calculator.

How to Use the Overtime Calculator

  1. 1

    Enter your hourly rate

    Type your regular hourly pay rate in dollars, for example 22.50.

  2. 2

    Enter the hours worked

    Enter the total hours worked in the period you are checking, such as one workweek. Decimal hours like 46.5 are accepted.

  3. 3

    Set the overtime threshold

    Leave it at 40 for the standard US weekly rule, or enter a different number of hours after which overtime starts, such as 8 for a single day.

  4. 4

    Choose the overtime multiplier

    Select 1.5x for time and a half or 2x for double time.

  5. 5

    Read your pay breakdown

    Regular pay, overtime pay, and total gross pay appear instantly, with the regular and overtime hours shown under each figure.

Results appear once both the hourly rate and hours worked are filled in. If the threshold field is left blank, the calculator uses 40 hours.

Overtime Pay Formula With Worked Examples

The calculator splits your hours at the threshold. Regular hours are the smaller of your hours worked and the threshold; overtime hours are anything above it. Regular pay is regular hours × rate, overtime pay is overtime hours × rate × multiplier, and total pay is the two added together.

  • Time and a half, weekly: $18 an hour, 52 hours, 40-hour threshold, 1.5x. Regular pay is 40 × $18 = $720.00, overtime is 12 × $18 × 1.5 = $324.00, and total pay is $1,044.00.
  • Double time, daily: $20 an hour, 10 hours in one day, 8-hour threshold, 2x. Regular pay is 8 × $20 = $160.00, overtime is 2 × $20 × 2 = $80.00, and total pay is $240.00.
  • No overtime: $25 an hour for 38 hours with a 40-hour threshold is all regular time: 38 × $25 = $950.00, with zero overtime pay.

To see what share of your paycheck came from overtime, divide overtime pay by total pay with the percentage calculator; in the first example, $324 of $1,044 is about 31%.

US Overtime Rules: Weekly, Daily, and Double Time

Under the federal Fair Labor Standards Act (FLSA), non-exempt employees must be paid at least 1.5 times their regular rate for every hour over 40 in a workweek. A workweek is any fixed, recurring seven-day period set by the employer, and each one stands alone: hours cannot be averaged across two weeks. Working 50 hours one week and 30 the next still means 10 overtime hours, even though the two-week total is exactly 80. For a biweekly paycheck, run the calculator once per week and add the results.

Federal law does not require daily overtime or double time, but some states and union contracts do. California, for example, requires time and a half after 8 hours in a workday and double time after 12. This calculator applies one threshold and one multiplier per calculation, so set the threshold to 8 for a daily check, and split a day that crosses into double time into two calculations. State rules change, so confirm your own state’s law or your employment contract.

Your FLSA regular rate can also be higher than your base wage, because certain non-discretionary bonuses and commissions must be folded into it. The calculator multiplies only the hourly rate you type in, so adjust that figure first if a bonus applies.

From Overtime Pay to Take-Home Pay

The total shown here is gross pay, before any tax or deduction. Overtime is taxed as ordinary wages, so to estimate what actually lands in your bank account, enter your gross pay into the paycheck calculator. Salaried workers who are non-exempt can find their hourly rate with the salary to hourly calculator, and if you want to see what a steady overtime schedule adds up to over a year, the hourly to salary calculator annualizes an hourly wage. Freelancers billing extra hours to a client can turn the result into a bill with the invoice generator.

Common uses

  • Checking that a pay stub pays overtime at the right rate
  • Estimating a paycheck before a week with extra shifts
  • Comparing what time and a half and double time pay for the same hours
  • Working out daily overtime for a long shift in a state with daily rules
  • Budgeting overtime labor costs for a small business payroll
  • Deciding whether picking up an extra shift is worth it

How is overtime pay calculated?

Under the US Fair Labor Standards Act, non-exempt employees earn 1.5× their regular rate for hours over 40 in a workweek. At $20 an hour, overtime pays $30. Some states add daily overtime rules that trigger before 40 weekly hours, so state law can be more generous than federal.
