Overtime Calculator

See expected gross from this week's total hours (federal 40-hour split)—or from confirmed regular, 1.5x OT, and 2x DT buckets—before you take numbers to payroll.

How do you want to enter hours?

Enter this week's total hours. Hours over 40 become 1.5x OT under the federal weekly baseline.

Expected Gross Pay
$1,375.00
Regular:$1,000.00
Overtime:$375.00
Double time:$0.00
Flat tax estimate

Optional flat percentage for a rough tax and net planning estimate.

Federal weekly baseline only
Hours above 40 show as 1.5x OT. Check the calculation details before you rely on this estimate.

How did we get this number?

Values, rates, and formulas for this estimate—open when you want to check the math.

Which values and rates were used?

Regular rate $25.00; total hours 50; auto-split into 40 regular, 10 OT, and 0 DT.

OT rate $37.50 at 1.5x; DT rate $50.00 at 2x.

What about the tax estimate?

Estimated tax
$302.50
Estimated net
$1,072.50

One flat percentage on expected gross—not withholding, take-home, deductions, filing status, or a tax-return result.

What math produced this gross?

Total hours were split at the federal 40-hour workweek baseline, then these formulas ran.

Regular: $25.00 × 40 hours × 1 = $1,000.00

Overtime: $25.00 × 10 hours × 1.5 = $375.00

Double time: $25.00 × 0 hours × 2 = $0.00

What does this estimate assume?
Total hours auto-split at the federal 40-hour workweek baseline. Not an eligibility, state daily, salary, or employer-policy decision. Switch to confirmed hour buckets if you already know regular / OT / DT.

Which example matches what you're checking?

Load one into the calculator, then edit every value to match your facts.

Illustrative only—not real cases, and not conclusions about anyone's pay.

Just a normal OT week?

One ordinary OT week on the federal 40-hour baseline.

What goes in?
$20 confirmed regular rate; 45 total workweek hours.
Why that gross?
40 regular + 5 at 1.5× → $800 + $150 = $950 expected gross.
When does this help?
See how total hours become earnings lines.
Pattern and limits
  • What transfers? Hours over 40 create a 1.5× OT line on this federal path.
  • What stays out of scope? Does not decide eligibility, state daily rules, or employer policy.

Longer week—and a rough tax take?

A 50-hour federal week plus an optional flat tax planning rate.

What goes in?
$25 confirmed regular rate; 50 total hours; 22% flat tax estimate.
Why that gross?
40 regular + 10 at 1.5× → $1,000 + $375 = $1,375 gross; ~$302.50 tax estimate.
When does this help?
Compare gross OT earnings with a rough flat-rate tax figure.
Pattern and limits
  • What transfers? Past 40 hours, straight-time and 1.5× OT split on separate lines.
  • What stays out of scope? Flat % is not exact withholding; the weekly split is not an eligibility decision.

Stub shows straight time + premium?

Same $25 / 50-hour week, shown the way some paystubs split lines.

What goes in?
$25 rate; 50 total hours; $1,250 straight time paid; $125 0.5× OT premium paid.
Why that gross?
Straight time for all 50 hours + OT premium = $1,375—comparison matches.
When does this help?
When the stub lists all hours at straight time and the extra premium alone.
Pattern and limits
  • What transfers? Full-rate OT and straight time + premium can equal the same gross.
  • What stays out of scope? Arithmetic only—does not validate payroll layout, classification, taxes, or compliance.

Is this the right calculator for your case?

Federal weekly estimate from total hours, or from hour buckets you already confirmed. It does not decide coverage, exemption, salary treatment, or state-law eligibility—use a specialist path below when your case is different.

Only need a 1.5x rate and a simple weekly total? Use the Time and a Half Calculator.

What can throw this estimate off?

Usually the week or the rate. Total Hours auto-splits at the federal 40-hour workweek baseline; confirmed hour buckets use the regular / OT / DT you already know. Neither path rebuilds a timecard, decides overtime eligibility, or covers salary, California daily rules, or OBBBA tax treatment.

Why can't I just add up the pay period?

Federal overtime runs on a fixed 168-hour workweek. A biweekly stub usually covers two weeks—so pay-period totals alone do not show which hours were OT.

Is my base hourly rate enough?

Nondiscretionary bonuses, commissions, shift differentials, and multiple rates can raise the regular rate. Enter a rate you have already confirmed for the period you are checking.

Check DOL Fact Sheet #56A

What should I do with the result?

  1. 1

    What do I enter first?

    Confirmed regular rate plus this week's total hours for a federal 40-hour split—or switch to confirmed regular, OT, and DT buckets. The first result is expected gross and its earnings lines.

  2. 2

    How do I check the numbers?

    Review hours, rates, multipliers, and formulas—including any auto-split from total hours. Wrong buckets or rate? Fix those before you compare a paystub.

  3. 3

    How do I match my paystub?

    From either input path, choose full-rate lines or straight time plus premiums. Enter every non-zero pre-tax earnings line before treating the total comparison as complete.

  4. 4

    What do I take to payroll or HR?

    Copy the neutral summary: inputs, formulas, expected vs entered amounts, differences, and facts still to confirm.

Where do these rules come from?

Rules last checked:

Each card links one federal boundary to the DOL source checked on that date. California daily overtime has its own official page and calculator.

Who maintains these boundaries?

This site—Overtime Calculator—maintains the page. Rule boundaries change only after a check against the sources below, using the federal weekly 40-hour baseline or the hour buckets you confirm.

Read our methodology for scope, source process, and other rule sets.

This is an arithmetic estimate from the facts you enter. It does not determine FLSA coverage, exemption status, state-law eligibility, contract rights, or whether a payroll practice is lawful. Confirm unresolved facts with payroll, HR, the relevant labor agency, or a qualified adviser.

Still stuck on a detail?

Total Hours mode: hours over 40 become 1.5x OT under the federal weekly baseline; double time stays at 0. Confirmed hour-bucket mode: multiply the regular, OT, and DT hours you enter by 1x, 1.5x, and 2x. Neither mode decides which hours legally qualify.
