How to Calculate Overtime Pay

Overtime pay at time and a half is required by federal law for any nonexempt employee who works more than 40 hours in a workweek. The formula is straightforward once you know the regular rate.

Run your own overtime math

Enter a rate and hours to see the overtime premium.

Time and a half means your regular hourly rate multiplied by 1.5. Federal law (FLSA) requires this rate for every hour a nonexempt employee works beyond 40 in a single workweek. Some states have daily overtime rules too, so always check your state's law.

The overtime formula, step by step

Worked example: hourly employee

ItemCalculationAmount
Regular rate$18.00/hr
Overtime rate (1.5x)$18.00 x 1.5$27.00/hr
Regular pay (40 hrs)40 x $18.00$720.00
Overtime pay (6 hrs)6 x $27.00$162.00
Total gross pay$882.00

What "double time" means

Some employers and some state laws (notably California) require double time, which is the regular rate x 2.0, for hours beyond a certain daily or weekly threshold. Double time is not required under federal law but may be required by your state or your employment contract.

Salaried nonexempt employees

Many salaried workers are still entitled to overtime. Find their effective hourly rate by dividing their weekly salary by 40, then apply the 1.5x formula for any hours over 40. A salaried employee earning $800/week has an effective rate of $20/hr and an overtime rate of $30/hr.

Which employees are exempt?

Executive, administrative, and professional employees who earn more than the salary threshold set by the Department of Labor are typically exempt from overtime. Exempt status depends on both job duties and salary level. When in doubt, check with the Department of Labor or your payroll provider. See how to calculate total hours worked first to know whether overtime applies.

State overtime laws that go beyond federal rules

Federal law sets the floor, but several states require overtime in situations where federal law would not. Key examples:

Always verify your state's current rules with the state labor agency or a qualified employment professional. This information is provided for general educational purposes only and is not legal advice.

How the FLSA workweek definition affects overtime

Overtime under the FLSA is calculated on a workweek basis, not a pay period basis. A workweek is any fixed recurring period of 168 hours, which is seven consecutive 24-hour periods. Employers choose the start day of their workweek (Sunday through Saturday are common choices), and that day is fixed unless there is a legitimate business reason to change it. This matters because a biweekly pay period covering two weeks contains two separate workweeks for overtime purposes. Hours from one week cannot be averaged into the other. If an employee works 36 hours in week one and 44 hours in week two of a biweekly pay period, they are owed overtime for 4 hours in week two even if the two-week average is 40 hours. Use the time card calculator to track each workweek separately and catch overtime before processing payroll.

The regular rate when employees receive bonuses or shift differentials

The "regular rate" used for overtime calculations is not always just the base hourly wage. Under the FLSA, most non-discretionary bonuses (production bonuses, attendance bonuses, and similar incentive pay) must be folded into the regular rate before computing overtime. For example, if an employee earns a $60 non-discretionary bonus in a 50-hour week, divide $60 by 50 to get $1.20 per hour, add that to the base rate, then apply 1.5x to the combined rate for overtime hours. Discretionary bonuses that are not announced in advance are generally excluded from the regular rate. This corner of wage law gets complicated fast; treat this page as a starting point and check the specifics with a payroll provider or employment attorney.

Two jobs, two rates, one overtime calculation

An employee who splits the week between roles at different pay rates does not get to pick which rate feeds the formula, and by default neither does the employer. The FLSA's standard method, spelled out in 29 CFR 778.115, is a weighted average: total the straight-time earnings from both rates, divide by total hours to find the regular rate, then pay an extra half of that rate for each overtime hour. Half, not 1.5, because the straight-time portion of every hour is already inside the weekly total.

ItemCalculationAmount
Warehouse hours32 x $19.00$608.00
Delivery hours12 x $23.00$276.00
Regular rate$884.00 / 44$20.09/hr
Overtime premium (4 hrs)4 x $20.09 x 0.5$40.18
Total gross pay$884.00 + $40.18$924.18

There is an alternative. With an agreement reached before the work is performed, the employer may instead pay 1.5 times the rate of whichever job the overtime hours were actually spent on. Absent that agreement, the weighted average controls.

The fluctuating workweek method

Some employers pay nonexempt workers a fixed salary for hours that swing week to week, then pay overtime as an extra half-time rather than full time and a half. The FLSA allows this (DOL Fact Sheet 82) when the salary is genuinely fixed, covers every hour worked at no less than minimum wage, and both sides clearly understand the arrangement. The math has a property worth seeing before you agree to it: the regular rate falls as hours rise. Here is a $600 fixed weekly salary across two different weeks.

WeekHoursRegular rateOvertime premiumTotal pay
Week 144$600 / 44 = $13.644 x $6.82 = $27.28$627.28
Week 250$600 / 50 = $12.0010 x $6.00 = $60.00$660.00

Ten overtime hours in week 2 added $60. Under the standard method, for a worker whose $600 salary covered a 40-hour week at an implied $15 rate, those same ten hours would have added $225. Several states, California and Pennsylvania among them, do not permit the fluctuating workweek under their own wage laws, so whether it can be used at all depends on where the work happens.

Overtime for tipped employees

The overtime rate for a tipped worker is computed on the full minimum wage, never on the $2.13 federal cash wage. At the $7.25 federal minimum, the overtime rate is $10.88. The employer may still take the same $5.12 tip credit against it, which leaves a cash overtime wage of $5.76 per hour. The recurring violation, common enough that the Department of Labor flags it in Fact Sheet 15, is multiplying $2.13 by 1.5 and paying $3.20 for overtime hours. That shorts the worker $2.56 an hour. States with a higher tipped minimum, or no tip credit at all, change the numbers, but the structure holds: overtime math starts from the full applicable minimum wage.

FAQs

What is time and a half?

Time and a half is an overtime pay rate equal to 1.5 times an employee's regular hourly rate. If you earn $16/hr, your time-and-a-half rate is $24/hr. Federal law requires it for nonexempt employees working more than 40 hours in a workweek.

How do I calculate my overtime pay?

Multiply your regular hourly rate by 1.5 to get the overtime rate, then multiply that by the number of hours worked over 40. Add that to your regular pay (40 x regular rate) for your total weekly gross pay. Example: $20/hr base, 5 overtime hours: ($20 x 40) + ($30 x 5) = $950.

Does overtime kick in after 8 hours a day or 40 hours a week?

Under federal law, overtime is triggered after 40 hours in a workweek, not per day. However, California and a few other states require overtime after 8 hours in a single day regardless of the weekly total. Check your state rules if you are outside those states.

What is the difference between overtime and double time?

Overtime (time and a half) is 1.5x the regular rate and applies after 40 hours per week under federal law. Double time (2x the regular rate) is not federally mandated but is required by some states like California for hours beyond 12 in a day or beyond 8 on the seventh consecutive day of a workweek.

Can my employer require me to work overtime?

Generally yes. The FLSA sets no limit on how many hours an adult employee can be scheduled in a week; it only requires the overtime premium once a nonexempt employee passes 40 hours. Refusing mandatory overtime can be grounds for discipline unless a contract, union agreement, or state rule says otherwise.

Is overtime taxed at a higher rate?

No. Tax brackets apply to annual income, so overtime dollars are taxed the same as regular dollars, even though withholding on one large check can temporarily run high. For federal tax years 2025 through 2028, workers can also deduct the extra half-time portion of FLSA-required overtime, up to $12,500 per year ($25,000 on a joint return), phasing out above $150,000 of modified adjusted gross income, under the tax law enacted in July 2025.

Does travel or training time count toward the 40 hours?

Often, yes. Required training during work hours and travel between job sites during the workday both count as hours worked under DOL rules. The ordinary commute from home to work does not. If counted time pushes the week past 40 hours, it earns the overtime rate like any other hour.

How far back can I claim unpaid overtime?

The FLSA statute of limitations is two years for most claims and three years when the violation was willful. State wage laws sometimes allow longer look-back periods, so a claim filed under state law can reach further than a federal one.
