Overtime calculator

This overtime calculator works out your regular pay, overtime at time and a half, and double time for a week. It uses the federal 40-hour rule, plus the daily overtime rules in California, Alaska, Nevada and Colorado.

  • Federal FLSA rule: 1.5× past 40 hours
  • Daily rules for CA, AK, NV and CO
  • Shows the overtime “half” used for the tax deduction

How to use the overtime calculator

  1. Enter your regular hourly rate and choose your state. Pick Federal only if your state is not listed.
  2. Enter the hours you worked on each day of your workweek, starting with the first day of the workweek. Or switch to a weekly total.
  3. Read your total pay, split into regular pay, overtime at 1.5× and any double time.
  4. Check the note under the figures for the rule that was applied.

How overtime pay is calculated

Overtime pay is your regular hourly rate times 1.5 for each overtime hour. Double time is your rate times 2.

total pay = regular hours × rate + overtime hours × rate × 1.5 + double-time hours × rate × 2

Federal rule (all states). Under the Fair Labor Standards Act, non-exempt employees get at least time and a half for hours worked over 40 in a workweek. A workweek is a fixed 168-hour period (seven 24-hour days) and weeks cannot be averaged.

States with daily overtime. Where a state pays overtime by the day, the daily overtime hours are counted first. Only the remaining regular hours count toward the 40-hour weekly limit, so no hour is paid overtime twice. California and Alaska spell this out; for 1.5× rules it gives the same result as paying whichever of the daily or weekly totals is larger, which is Colorado’s rule.

Worked example

A California worker earning $20.00 an hour works three 13-hour days in one workweek (39 hours in total).

  1. Each day: hours 1 to 8 are regular, hours 9 to 12 are overtime at 1.5×, and hour 13 is double time.
  2. For three days: 24 regular hours, 12 overtime hours and 3 double-time hours.
  3. Regular pay: 24 × $20.00 = $480.00. Overtime: 12 × $30.00 = $360.00. Double time: 3 × $40.00 = $120.00.
  4. Total: $480.00 + $360.00 + $120.00 = $960.00.

Under the federal rule alone, 39 hours is under 40, so the same week pays 39 × $20.00 = $780.00. Choose California and enter 13, 13 and 13 to see the $960.00.

Overtime rules by state

Every state follows the federal 40-hour rule. These states add a daily rule. Last checked 28 October 2026.

StateTime and a half (1.5×)Double time (2×)
Federal (FLSA)Over 40 hours in a workweekNone required
CaliforniaOver 8 hours in a workday, over 40 in a workweek, and the first 8 hours on the 7th consecutive day worked in a workweekOver 12 hours in a workday, and over 8 hours on the 7th consecutive day
AlaskaOver 8 hours in a day or 40 in a week (employers with 4 or more employees)None
NevadaOver 40 hours a week; also over 8 hours in a 24-hour workday if paid under $18.00 an hour (1.5 × the $12.00 minimum wage), unless on an agreed four 10-hour day scheduleNone
ColoradoOver 40 hours a workweek, 12 hours a workday, or 12 consecutive hours, whichever pays moreNone

California’s seventh-day rule applies only when you work all seven days of the same workweek. This calculator does not model Colorado’s 12-consecutive-hours rule for shifts that cross the start of a workday, alternative workweek schedules, or industry exemptions.

Overtime and the federal tax deduction

Starting with 2025 tax returns, federal income tax law lets eligible workers deduct “qualified overtime compensation”: the extra half of the time and a half that the FLSA requires. If you earn $20.00 an hour and work 50 hours, the 10 overtime hours pay $30.00 each, and the deductible part is the $10.00 premium on each hour, or $100.00. Under IRS guidance it covers only overtime the FLSA requires (hours over 40 in a workweek), and pay above 1.5× does not count.

The deduction is capped at $12,500 a year ($25,000 on a joint return) and phases out when modified adjusted gross income is over $150,000 ($300,000 joint). The “Federal premium” figure in the calculator shows that half for the week. Last checked 28 October 2026; ask a tax professional about your own return.

Common questions

How do I calculate my overtime rate?

Multiply your regular hourly rate by 1.5. At $20.00 an hour, overtime is $30.00 an hour, and double time is $40.00 an hour.

How much is 10 hours of overtime?

Ten overtime hours pay 10 × 1.5 × your hourly rate. At $20.00 an hour that is $300.00, on top of $800.00 for the first 40 hours, so a 50-hour week pays $1,100.00.

Is overtime after 8 hours a day?

Not under federal law, which counts only hours over 40 in a workweek. California, Alaska and Nevada (for workers under $18.00 an hour) pay overtime after 8 hours in a day, and Colorado after 12.

When does double time start in California?

California pays double time for hours over 12 in a workday, and for hours over 8 on the seventh consecutive day worked in a workweek.

How is overtime calculated on a biweekly paycheck?

Overtime is figured for each workweek separately; two weeks cannot be averaged. Working 45 hours one week and 35 the next gives 5 overtime hours, even though the total is 80.

Is overtime pay tax free now?

Not entirely. Eligible workers can deduct the extra half of FLSA-required time and a half, up to $12,500 a year ($25,000 joint), with a phase-out above $150,000 of modified AGI ($300,000 joint). The rest of your overtime pay is still taxed.
