Overtime Pay Calculator

U.S. only tools

Overtime is not simply "more hours at the same rate". Federal law requires a premium of at least half the regular rate for every hour worked beyond 40 in a week, so those hours are paid at 1.5 times the regular rate — and the regular rate is not always the number on the contract.

Straight-time pay per hour, before the premium and before a bonus is spread into it.

Hours paid at the normal rate. Anything you enter above 40 in a week is moved to the overtime line automatically, because federal law makes hours past 40 overtime.

Hours past the weekly threshold, paid at the multiplier below.

1.5 is the federal minimum; a contract or state law may require more.

Used by states such as California after 12 hours in a day.

Where the week's pay comes from

  • Straight time$1,200.00
  • Overtime premium$100.00

The premium is the extra half (or more) paid only because those hours were overtime, on top of the straight-time pay for the same hours.

The week in detail

ItemHoursRateAmount
Straight time48$25.00$1,200.00
Overtime at 1.5x8$37.50$300.00
Weekly gross$1,300.00

Straight-time earnings cover every hour worked at the regular rate, bonus included; the premium lines are what the overtime hours earn above that.

Annual gross$67,600.00
Overtime hours a year416
Extra pay from premium and bonus this week$100.00
Extra pay from premiums and bonuses this year$5,200.00

The extra is the difference between this week and the same hours paid entirely at the straight-time rate, and that baseline leaves the bonus out - so this row carries this week's whole bonus as well as the overtime premium. The premium line above is the overtime premium on its own.

Federal law requires 50% above the regular rate for hours worked past 40 in a week, and there is no federal daily limit. States may go further — California and a few others require double time after 12 hours in a day. Salaried employees who meet the exemption tests are not entitled to overtime at all.

This calculator builds the week from the ground up: straight time, the overtime premium, any double-time hours, and the effect of a bonus on the rate the premium is calculated from.

About this overtime calculator

Overtime is one of the few pay questions with a federal answer: above 40 hours in a workweek the Fair Labor Standards Act requires at least one and a half times the regular rate, and a state may require more but not less.

The page adds the premium to your regular, overtime and double-time hours, lifts the regular rate when a nondiscretionary bonus belongs in it, and stops there: the exemption tests, state daily rules and the tax treatment of the larger check are named rather than guessed. The result is gross pay for the week and the year, and it is arithmetic on the rule rather than a payroll department.

How this overtime calculator works

The 40-hour weekly rule

The federal standard is a workweek of 40 hours. Everything above that is overtime, paid at one and a half times the regular rate. A 50-hour week is 40 hours of straight time plus 10 hours at 1.5x, which is the same as 45 hours at the normal rate.

The 40 hours is a weekly measure, not a daily one. Working 12 hours on Monday and 28 over the rest of the week is not federal overtime, even though the days are long. California and a handful of other states do impose daily overtime, which the multiplier and double-time fields let you model.

The regular rate is not always the hourly wage

The premium is calculated on the regular rate, which includes nondiscretionary payments: production bonuses, shift differentials, and commissions that are tied to hours worked. A $90 weekly bonus spread across 45 hours raises the regular rate from $20 to $22, and the overtime premium rises with it.

Discretionary bonuses, expense reimbursements and most gifts are excluded. This is why a bonus week and a normal week can produce different overtime even when the hours are identical.

The regular rate is the legal term for the denominator the premium is built on, and it is wider than the hourly wage on the contract. Nondiscretionary payments - production bonuses, shift differentials and commissions tied to hours worked - are added into it, so the premium is calculated on a number that can change from week to week, while discretionary gifts, expense reimbursements and similar one-offs stay out, which is why an identical set of hours can price differently in a bonus week.

Who is not entitled to overtime

Salaried employees who meet the duties and salary tests for the executive, administrative or professional exemptions are not entitled to overtime pay, no matter how many hours they work. Misclassifying a role to avoid overtime is one of the most common wage violations.

Also outside the federal rule: independent contractors, some agricultural workers, and certain transportation employees covered by other statutes.

The exemption is a test, not a title: a role labeled "manager" still owes overtime unless it actually meets the salary and duties tests for the executive, administrative or professional categories. Misclassifying a worker to dodge the premium is one of the most common wage-and-hour violations, and the page’s note is a reminder that the overtime entitlement is a legal floor the employer cannot contract away.

Gross pay is not take-home pay

Every figure here is gross: the premium is added to the wage before any deduction, and income tax and FICA come out afterwards. Overtime hours are taxed at the same marginal rate as the hours beside them, so a bigger check does not mean a higher rate on the extra hours - only more withheld in that period.

An estimate, not a return, and not tax advice.

Every figure on the page is gross, before income tax and FICA, and the annual row simply repeats the week across the number of weeks you enter, so it is an estimate of gross earnings rather than a forecast of a tax return. The higher weekly check comes with more withheld, not a higher rate on the extra hours, which is why the premium shows up in gross pay and only partly survives tax time.

Salaried, non-exempt, and the fluctuating workweek

Being paid a salary does not by itself remove the overtime premium. The exemption tests look at duties and at the salary basis, not at the label on the offer letter, so a salaried assistant manager who spends the week on the till is usually owed the premium while a genuine executive is not.

When a salaried employee is non-exempt, many employers use the fluctuating workweek method: the weekly salary is divided by the hours actually worked, so the regular rate falls as the week gets longer and the premium is half of that lower rate. It is legal only when the salary is genuinely meant to cover all hours worked, and it produces a smaller premium than dividing by 40 - which is why several states do not allow it.

Bonuses and shift differentials are the other trap. A nondiscretionary bonus has to be spread back over the weeks it was earned and the premium recalculated, so a bonus paid in December can create a small true-up payment for overtime worked in the summer, while a discretionary bonus never enters the regular rate at all.

Worked examples

Each example below was run through the calculator on this page when the site was built, so the numbers match what you see when you enter the same inputs.

48-hour week at $25 an hour

Regular hourly rate: $25.00 · Straight-time hours: 40 hours · Overtime hours: 8 hours · Overtime multiplier: 1.5 x · Double-time hours: 0 hours · Bonus earned this week: $0.00 · Weeks like this per year: 52 weeks

Gross pay for the week

$1,300.00

48 hours: 40 at $25.00 plus 8 at the premium rate.

Regular rate used: $25.00 · Overtime premium: $100.00 · Blended hourly rate: $27.08 · Annual pay at this pattern: $67,600.00

Eight overtime hours add $100 of premium: the same hours at straight time would be $1,200, not $1,300.

The same week with a $90 bonus

Regular hourly rate: $25.00 · Straight-time hours: 40 hours · Overtime hours: 8 hours · Overtime multiplier: 1.5 x · Double-time hours: 0 hours · Bonus earned this week: $90.00 · Weeks like this per year: 52 weeks

Gross pay for the week

$1,397.50

48 hours: 40 at $26.88 plus 8 at the premium rate.

Regular rate used: $26.88 · Overtime premium: $107.50 · Blended hourly rate: $29.11 · Annual pay at this pattern: $72,670.00

The bonus lifts the regular rate, so the overtime premium is calculated on a higher base.

56-hour week with double time

Regular hourly rate: $22.00 · Straight-time hours: 40 hours · Overtime hours: 12 hours · Overtime multiplier: 1.5 x · Double-time hours: 4 hours · Weeks like this per year: 48 weeks

Gross pay for the week

$1,452.00

56 hours: 40 at $22.00 plus 16 at the premium rate.

Regular rate used: $22.00 · Overtime premium: $132.00 · Blended hourly rate: $25.93 · Annual pay at this pattern: $69,696.00

The double-time hours model a state daily rule such as California’s after 12 hours in a day.

Season of long weeks

Regular hourly rate: $30.00 · Straight-time hours: 40 hours · Overtime hours: 15 hours · Overtime multiplier: 1.5 x · Double-time hours: 0 hours · Bonus earned this week: $0.00 · Weeks like this per year: 16 weeks

Gross pay for the week

$1,875.00

55 hours: 40 at $30.00 plus 15 at the premium rate.

Regular rate used: $30.00 · Overtime premium: $225.00 · Blended hourly rate: $34.09 · Annual pay at this pattern: $30,000.00

Fifteen extra hours a week for a season is worth a five-figure premium over the year.

Frequently asked questions

How is time and a half calculated?

Multiply the regular rate by 1.5 and pay it for every hour above 40 in the workweek. Equivalently, pay all hours at the regular rate and add a half-rate premium for the overtime hours — the two methods give the same total.

Is overtime after 8 hours a day or 40 hours a week?

Federally, 40 hours a week. Alaska, California, Nevada and a few other states also require daily overtime after 8 or 12 hours, and California requires double time after 12. Whichever rule gives more pay applies.

Does a bonus change my overtime rate?

A nondiscretionary bonus does. It is allocated across the hours worked in the period it was earned, which raises the regular rate and therefore the premium. Discretionary bonuses, gifts and expense reimbursements do not.

Are salaried employees paid overtime?

Only if they are non-exempt. Salaried employees who meet the duties test and earn at or above the salary threshold for the executive, administrative or professional exemption are exempt, and their pay does not change with hours.

Is overtime taxed at a higher rate?

No. Overtime is ordinary income and taxed at your marginal rate. Because the paycheck is larger, more tax is withheld in that period, but the annual liability is unchanged and any excess comes back at filing.

Can my employer require overtime?

In most US states, yes — an employer can require reasonable overtime and discipline an employee who refuses it. The requirement is that the hours are paid correctly, not that they are voluntary.

Does overtime count towards my Social Security record?

Yes. All taxable wages, overtime included, count towards the earnings record used to calculate Social Security benefits, and they are subject to the same 6.2% tax up to the annual wage base.

Assumptions and sources

  • The federal overtime premium of at least 1.5 times the regular rate for hours over 40 in a workweek follows the Fair Labor Standards Act; state rules can require more.
  • The regular rate includes nondiscretionary bonuses, shift differentials and commissions tied to hours worked, as set out in the US Department of Labor overtime rules.
  • Pay is shown as gross: income tax and FICA are not deducted here.
