You've just worked the busiest week of the month. You're tired, your feet hurt, and then your pay stub lands — and the number looks... small. Not obviously wrong. Just smaller than you expected for all those extra hours. So you do some rough math in your head and wonder if you're missing something, or if payroll is.
You're not alone in that moment. Overtime is one of the most misunderstood parts of a paycheck. Some people assume every hour past eight in a day pays extra. Others think a Sunday automatically means time and a half. Plenty of folks have no idea a bonus can change their overtime rate, or that a new federal tax deduction now covers part of what they earn on overtime hours.
Let's fix that. This guide covers what overtime pay is, how the federal rule works, how to calculate overtime pay yourself with real numbers, and how to spot the quiet mistakes that shave dollars off a check.
The basic rule: 40 hours in a week, then time and a half
Start with the federal law, because everything else builds on it. The Fair Labor Standards Act (the FLSA) says non-exempt employees in the US must be paid at least 1.5 times their regular rate for every hour worked over 40 in a single workweek. That 1.5 rate is "time and a half."
First, it's per workweek, not per pay period. Paid every two weeks, working 45 hours one week and 35 the next? That's still five overtime hours. Your employer can't average the two weeks into a neat 40 and 40 to make the extra pay disappear.
Second, federal law has no daily overtime rule at all. Working 12 hours on a Tuesday triggers nothing under the FLSA by itself, as long as your weekly total stays at 40 or under. There's also no federal requirement to pay extra for weekends, nights, or holidays. A Christmas Day premium comes from state law, your employer's policy, or a union contract — not Washington.
So what is overtime pay, in plain terms? Not a bonus or a gift for being a team player. It's a legal minimum price for your time past 40 hours a week, set high on purpose so your 50th hour costs more than your 10th.
Your regular rate is probably higher than your hourly wage
Here's the detail that trips up even careful people. "Regular rate" doesn't always mean the hourly number on your offer letter. It's supposed to include most of what you earn for your work that week — base pay, yes, but also shift differentials and non-discretionary bonuses.
Say you earn $20 an hour and got a $100 production bonus in a week where you worked 45 hours. The shortcut is to pay overtime as 1.5 times $20 and treat the bonus separately. The FLSA math is pickier: the bonus gets folded into your total pay for the week first, which nudges your regular rate up — and every overtime hour with it. On one check the difference might be a few dollars. Over a year of heavy overtime, it stops being a few dollars.
Not everything counts. Discretionary gifts, expense reimbursements, and paid time off generally sit outside the regular rate. And hours you were paid for but didn't work — a holiday where the plant was closed, say — don't count toward the 40-hour threshold. Overtime is about hours actually worked: take Monday off for a holiday, work Tuesday to Saturday at eight hours a day, and you've worked 40 hours, not 48, even though you were paid for 48.
We built the calculator on this site largely because of this wrinkle. People ran their numbers with just their base wage and felt sure payroll had shorted them. Sometimes it had. Sometimes the bonus math explained the gap.
How to calculate overtime pay, step by step
The calculation isn't hard. First, find your regular rate for the week — with a single hourly wage and nothing else, that's just your wage. Second, split your hours at 40. Third, pay the overtime hours at 1.5 times the regular rate and add the two piles together.
One thing to watch: some stubs list all your hours at the straight rate, then add a separate half-rate "overtime premium" line for the extra 0.5 on top. That method is legitimate — it's the same time-and-a-half pay split into two lines. Other stubs list overtime hours at the full 1.5 rate. Both arrive at the same place if the math is honest.
Marcus earns $22 an hour and works 47 hours in one week.
Regular pay: 40 hours × $22 = $880
Overtime pay: 7 hours × $33 (that's $22 × 1.5) = $231
Gross pay for the week: $880 + $231 = $1,111
Paid straight time for all 47 hours, Marcus would have gotten $1,034. The overtime rule put an extra $77 in his check — hold onto that $77, because it matters again in the tax section.
If your pay includes a bonus or a differential, do the longer version: add up everything you earned that week at straight time, divide by the hours you actually worked, and that's your regular rate. Overtime hours then earn an extra half of that rate on top.

Calculate my overtime payState rules can pay you more than the federal floor
The FLSA is a floor, not a ceiling. States are free to be more generous, and several are — mostly by adding the daily rules federal law skips. California is the best-known example.
Under California law, you earn 1.5 times your rate after eight hours in a day, double time after 12 hours in a day, plus extra rules for the seventh straight day of work in a workweek. Alaska and a few other states have daily thresholds of their own, and some states set weekly thresholds lower than 40. Details vary, so check your own state's labor department page — that's the source that counts, not a coworker's memory of their last job.
A California worker earning $20 an hour works one 11-hour day.
First 8 hours at straight time: 8 × $20 = $160
Next 3 hours at time and a half: 3 × $30 = $90
Total for the day: $160 + $90 = $250
Under federal law alone, that day would pay $220 if the week stayed under 40 hours — the daily spike wouldn't matter. California's rule is worth $30 on this one shift.
Who doesn't get overtime at all?
Everything above applies to non-exempt employees. Exempt employees don't have a legal right to that 1.5 rate, no matter how many hours they work. A 55-hour week for a truly exempt employee pays the same salary as a 38-hour week.
The mistake people make is assuming a salary automatically means exempt. It doesn't. Exemption generally turns on two things together: how you're paid, including a federal salary threshold that has to be met, and what your actual job duties are. Many executive, administrative, professional, outside sales, and certain computer roles can qualify — but the title on your business card isn't the test. Your day-to-day duties are.
States set their own thresholds and twists on top of the federal ones, so the line sits in different places depending on where you work. If you're salaried, putting in regular 50-hour weeks, and your job looks a lot like the hourly jobs around you, raise the question — first with HR, and if the answer feels thin, with your state labor agency or an employment lawyer. Misclassification is one of the most common overtime problems out there, and it usually affects whole teams at once.
One combination confuses people: you can be paid a salary and still be non-exempt, meaning your salary covers straight-time hours and you still earn the premium past 40. If that's you, ask payroll how they turn your salary into a regular rate.
The new tax break: "no tax on overtime," with fine print
You've probably seen "no tax on overtime" in headlines. The reality, under the One Big Beautiful Bill, is narrower and still useful — if you know what counts. For tax years 2025 through 2028, workers can claim a deduction for qualified overtime. Here's how to calculate qualified overtime without overstating it: only the premium portion counts. Not the whole overtime rate. Just the extra 0.5 on top of your regular rate.
Go back to Marcus. His premium was $11 an hour — the half above his $22 base — across seven overtime hours. That's 7 × $11 = $77 of deductible premium for that week, not $231. Work a similar schedule all year and those halves stack into a deduction worth claiming — but it's a stack of halves, not of whole overtime checks.
Two more limits matter. First, the overtime has to be the kind the FLSA requires — hours over 40 in a workweek. Overtime earned only because of a state daily rule, like that California 11-hour day, doesn't qualify. Neither does extra pay your employer hands out voluntarily, like a weekend premium no law required. Second, this is a deduction, not tax-free paychecks: nothing changes in your weekly withholding. You claim it on your tax return, it reduces your taxable income, and your benefit depends on your tax bracket. Income limits and phase-outs apply, so higher earners may see it shrink or disappear.
Our calculator estimates the deductible premium alongside your gross pay. Treat the estimate as a planning figure, not a filing figure — a tax professional has the final word.
Checking your own pay stub in two minutes
So, how much is overtime pay supposed to be on your specific stub? Confirm the workweek dates printed on it and count your hours actually worked inside them — not scheduled hours, worked hours. Split at 40. Run your rate, including any bonus or differential that belongs in it. Then compare line by line, remembering some employers show the premium as its own line.
The most common honest mistakes are small: hours that landed in the wrong week because a shift crossed midnight, a bonus never folded into the rate, a differential averaged away. The most common dishonest pattern is averaging two weeks together so a heavy and a light week cancel out. See a two-week total with no weekly split on the stub? Ask about that first.
If the numbers don't match, start boring and friendly. Bring your timesheet records — photos of the schedule, your clock-in app history — and ask payroll to walk the math with you. Most discrepancies die right there, in either direction. If you're told it's because you're exempt, ask which exemption and how your duties fit it. If you hit a wall, state labor agencies take wage questions for free. And keep your records either way: a folder of pay stubs is dull right up until the day it's the most useful thing you own.

Check my pay nowFrequently asked questions
What is overtime pay?
Overtime pay is the higher rate non-exempt employees must receive for hours over 40 in a single workweek — at least 1.5 times their regular rate under the Fair Labor Standards Act. Some states add daily rules on top.
How does overtime work if I'm paid every two weeks?
Week by week, not per pay period. Work 45 hours in week one and 35 in week two and you're owed five overtime hours, even though your two-week total is exactly 80. An employer can't average the weeks away.
Do I get overtime for working weekends or holidays?
Not under federal law by itself. The FLSA requires the premium past 40 hours in a workweek, whichever days those hours fall on. Weekend or holiday premiums come from state law, company policy, or a union contract.
How much of my overtime is tax-deductible under the new law?
For tax years 2025–2028, only the premium portion — the extra 0.5 above your regular rate — and only for FLSA-required overtime. State daily overtime and voluntary premiums don't qualify, phase-outs apply, and you claim it on your tax return.
I'm salaried. Am I exempt from overtime?
Not automatically. Exemption depends on a salary threshold and your actual duties, and states vary. Plenty of salaried workers are non-exempt and still owed a premium past 40 hours, so ask payroll how your role was classified.
