How to calculate overtime for salaried employees: the regular rate of pay, bonuses and the fluctuating workweek
To calculate overtime for a salaried non-exempt employee, divide the weekly salary by the number of hours it is intended to compensate to get the regular rate, add in any nondiscretionary bonuses or shift premiums earned that week, then pay 1.5 times that rate for every hour past 40. The division is the easy part. Nearly every real mistake comes from using base salary as the regular rate when something else should have been folded in first.
Before any of this matters, confirm the person is actually entitled to overtime. Paying a salary does not make a role exempt. The job has to clear the minimum salary level and pass a duties test, and if it fails either one the employee is salaried non-exempt and this arithmetic applies. The full test is on our page on exempt vs non exempt employees, and the 2026 salary floors are on the exempt salary threshold page.
Step 1: find the regular rate
The regular rate is the hourly figure overtime is built on. For a weekly salary, 29 CFR 778.113 says to divide the salary by the number of hours the salary is intended to compensate. That phrase carries weight. It is not automatically 40. If you hired someone at $875 a week for a 35-hour schedule, the regular rate is $25.00, not $21.88.
A worked example. An operations coordinator earns $1,000 a week for a standard 40-hour schedule and works 46 hours in a busy week. The regular rate is $1,000 divided by 40, or $25.00. Overtime is 1.5 times that, $37.50. The week costs $1,000 for the first 40 hours plus six hours at $37.50, which is $1,225.00.
Salaries paid on any other cycle get converted first. Multiply a monthly salary by 12 and divide by 52 for the weekly equivalent. Multiply a semimonthly salary by 24 and divide by 52. A $5,200 monthly salary works out to $1,200 a week, so a 40-hour schedule gives a $30.00 regular rate. Dividing the monthly figure by four is close enough to look right and wrong often enough to create back pay, because there are 4.33 weeks in an average month.
Step 2: add everything that belongs in the regular rate
This is where the money is. The regular rate is not base pay. It is total compensation for the week divided across the hours, minus a short list of statutory exclusions. Nondiscretionary bonuses belong in it. So do production and attendance incentives, shift differentials, hazard pay, on-call premiums and most commissions. Anything you promised in advance for hitting a target is nondiscretionary, whatever your policy calls it.
Take the same coordinator. Salary $1,000 for a 40-hour schedule, 45 hours worked, plus a $200 production bonus that was promised for hitting a weekly target. The salary side is $1,000 for the first 40 hours and five hours at $37.50, so $1,187.50. Then the bonus. It raises the regular rate by $200 divided by the 45 hours worked, which is $4.44, and an extra half-time premium is owed on that increment for the five overtime hours: 5 times 0.5 times $4.44, or $11.11. The week costs $1,398.61.
Eleven dollars is not what hurts. What hurts is that the same eleven dollars is missing from every bonus week for every person in the job code, for two or three years, and then doubles as liquidated damages. Overtime recalculation on bonuses is one of the most common findings in a wage and hour audit precisely because the individual amounts look too small to bother with.
Bonuses that cover a longer period work the same way with an extra step. A quarterly bonus is allocated back across the weeks it was earned in, and the additional half-time premium is recomputed for the overtime hours in each of those weeks. If the bonus cannot be tied to particular weeks, allocating it evenly across the period is generally acceptable. The practical move is to write the allocation method into the bonus plan document up front, and to keep the recurring obligations that flow from it tracked in one place rather than in whoever runs payroll that quarter.
Step 3: decide which of the two methods you are using
There are two lawful ways to pay overtime on a salary, and they produce very different numbers for the same person in the same week. Most employers use the first without knowing the second exists.
| $600 salary, 48 hours worked | Standard method | Fluctuating workweek |
|---|---|---|
| What the salary buys | A set schedule, usually 40 hours | Straight time for every hour worked, however many |
| Regular rate | $600 / 40 = $15.00 | $600 / 48 = $12.50 |
| Overtime multiplier | 1.5 times the rate for 8 hours | 0.5 times the rate for 8 hours, since straight time is already paid |
| Overtime owed | 8 x $22.50 = $180.00 | 8 x $6.25 = $50.00 |
| Total for the week | $780.00 | $650.00 |
| Catch | Costs rise steeply with hours, which is the point | Five conditions must all hold, and the rate falls as hours rise |
The $130 gap on one week is why the fluctuating workweek method attracts employers, and why plaintiffs' lawyers look hard at whether the conditions were met. Under 29 CFR 778.114(a) all five have to hold: hours genuinely fluctuate week to week, the salary is fixed and does not vary with hours, the salary is high enough to clear minimum wage even in the longest week, employer and employee have a clear and mutual understanding that the fixed salary covers all hours worked, and the extra half-time premium is actually paid on top.
The regulation's own example is worth having. An employee on $600 a week whose hours vary works 37.5, 44, 50 and 48 hours over four weeks. The regular rate in each week is $16.00, $13.64, $12.00 and $12.50, and the pay is $600.00, $627.28, $660.00 and $650.00. Notice what happens between the third and fourth weeks: two extra hours of work added $10.00 of pay, because the regular rate itself fell from $12.50 to $12.00 as the hours went up. Each additional hour is worth less than the one before it. That is lawful under this method, and it is exactly why the clear and mutual understanding requirement is the condition that gets litigated.
One detail people get wrong: bonuses and premiums are compatible with the fluctuating workweek method, and they still go into the regular rate. The 2020 revision to the rule confirmed that explicitly. What breaks the method is a salary that moves with hours worked, which is what happens the first time somebody docks a short week.
The five mistakes that create back pay
Averaging across a pay period. Overtime is owed per workweek, a fixed and regularly recurring 168-hour period. A 48-hour week followed by a 32-hour week owes eight hours of overtime, not zero, even though the biweekly total is 80.
Using base salary as the regular rate. Covered above, and it is the single biggest source of quiet liability.
Paying comp time instead of cash. Private-sector employers cannot substitute time off in a later week for overtime pay. Public agencies can, under narrow conditions. Most small companies that offer comp time believe it is a generous perk and are actually running an unpaid overtime program.
Not counting hours that count. Required training, mandatory travel during the workday, and work performed on a phone after hours are compensable. If a non-exempt employee answers messages at 9pm on a manager's request, that time is hours worked, and unrecorded hours worked are still owed.
Ignoring the state layer. Federal law is a floor. California requires overtime past eight hours in a day and double time past twelve, plus overtime on the seventh consecutive day. Alaska, Nevada and Colorado have daily overtime rules of their own. Compute the federal weekly figure and the state figure, and pay whichever is higher.
Set the salary with the overtime in it
The reason this arithmetic belongs in a compensation conversation rather than a payroll one is that the salary number itself should be chosen knowing what the overtime will cost. A role expected to run 46-hour weeks in peak season on the standard method costs about 12 percent more than its base salary suggests over a year. Budgeting that role at base and discovering the rest in Q4 is a planning failure, not a compliance one, but it feels identical when it lands.
Price the role against real market data first, then decide the schedule and the method, then model the total. If you are building the band from scratch, the mechanics are in our guide to creating salary bands, and the wider grid those bands sit in is covered under salary structure. If the reason you are reading this is that a role just failed its duties test, the sequence for moving someone across without creating a second problem is in reclassifying exempt to non-exempt.
How do you calculate overtime for a salaried employee?
Divide the weekly salary by the number of hours the salary is intended to compensate to get the regular rate, then pay 1.5 times that rate for every hour past 40 in the workweek. A $1,000 salary covering a 40-hour schedule gives a regular rate of $25.00, so a 46-hour week costs $1,000 plus six hours at $37.50, which is $1,225.
What is the regular rate of pay?
The regular rate is the hourly figure overtime is calculated from, and it is usually higher than base pay. It includes nondiscretionary bonuses, production and attendance incentives, shift differentials and commissions, not just the salary. Only specific categories listed in section 7(e) of the FLSA, such as genuinely discretionary bonuses and gifts, can be left out.
Is overtime calculated per week or per pay period?
Per workweek, always. A workweek is a fixed and regularly recurring period of 168 hours, seven consecutive 24-hour periods, and it does not have to match your pay cycle or the calendar week. Averaging two weeks of a biweekly period together is a violation even when the total looks fine.
