Overtime pay is one of those things everyone assumes they understand until they actually try to calculate their own paycheck. Then the questions start. Is it time and a half or double time? Does it kick in after 40 hours or 8 hours in a day? What about holidays? Let's walk through how this works so you can check your next paycheck and make sure you're getting what you're owed.
The basic formula
In the US, overtime usually means any hours worked past 40 in a single workweek. For those hours, your employer has to pay you at least 1.5 times your regular rate. This is where the phrase “time and a half” comes from.
Here's the math:
Overtime Pay = Regular Hourly Rate × 1.5 × Overtime Hours
Say you make $20 an hour and you worked 48 hours this week. The first 40 are paid at your regular rate: 40 × $20 = $800. The extra 8 hours are paid at time and a half: 8 × $20 × 1.5 = $240. Your total pay for the week is $1,040.
Double time (and when it applies)
Some states and some union contracts include double time, which is 2 times your regular rate. California is the most well-known example. There, you get double time after 12 hours in a single day, or after 8 hours on the seventh day of work in a row.
If you're not in California or in a union, double time is usually only offered on holidays, and even then it's voluntary on the employer's part. Federal law doesn't require it.
A full week example
Let's do a realistic example. You work at a warehouse making $18 an hour. This week you put in:
- Monday: 10 hours
- Tuesday: 10 hours
- Wednesday: 9 hours
- Thursday: 10 hours
- Friday: 8 hours
Total: 47 hours. The first 40 are regular: 40 × $18 = $720. The extra 7 are overtime: 7 × $18 × 1.5 = $189. Your gross pay is $909.
Our overtime calculator handles this in a few clicks. You put in your hourly rate, regular hours, overtime hours, and it shows you the breakdown.
Salaried employees and overtime
This is where things get murky. Not everyone who's paid a salary is exempt from overtime. It depends on your job duties and how much you make. Under US federal law, if you earn less than about $35,568 a year and fit certain criteria, you still qualify for overtime even on a salary. The rules are complicated and they've been updated recently, so check the Department of Labor website or talk to HR if you're not sure.
Common salaried jobs that are exempt: executives, most professionals with advanced degrees, outside sales staff, and certain computer workers. Common jobs that are NOT exempt: inside sales, admin assistants, retail managers (in many cases), and hourly workers who were bumped up to salary.
Calculating overtime when your rate changes
Some folks earn different rates for different tasks. Maybe you make $15 an hour at one job site and $20 at another, but work for the same company. In that case, your overtime rate is based on the weighted average of your hourly rates for the week.
Here's how it works. Total earnings for the week divided by total hours gives you your regular rate of pay. Then the overtime premium is half of that rate times the overtime hours (because you've already been paid the straight time).
Sounds confusing? Yeah, it is. If this applies to you, ask HR for a clear breakdown of how they calculate it.
Holiday pay vs overtime
People mix these up all the time. Holiday pay is extra money your employer gives you for working on a recognized holiday like Christmas or Thanksgiving. Federal law doesn't require this. It's a benefit your company chooses to offer.
Overtime is separate. Even if you're working a holiday, you only get overtime pay if you cross 40 hours for the week. That said, many good employers will pay both, and the combined pay can be substantial.
Other countries do it differently
In the UK, there's no legal minimum overtime rate. Your contract has to spell it out. In the UAE, overtime is 1.25x on weekdays and 1.5x at night or on days off, with some jobs excluded entirely. In Pakistan, overtime is 2x for factory workers under the Factories Act. Every country is different, so if you're not in the US, check your local labor laws.
Things people get wrong
- “My boss says I don't get overtime because I'm on salary.” Not always true. Check if you meet the exempt criteria.
- “I worked 12 hours on Tuesday, so I get overtime for 4 hours.” Usually no. Overtime is based on the week, not the day (except in California and a few other places).
- “Comp time instead of overtime pay is fine.” In private sector jobs, this is generally illegal. Government jobs can offer comp time, private ones usually can't.
- “I'm a 1099 contractor so I should get overtime.” Nope. True independent contractors don't qualify. But if your boss is treating you like an employee while calling you a contractor, you may be misclassified.
Check your paycheck
Run your numbers through our overtime calculator and compare with what you actually got paid. If the numbers don't match, ask your payroll department. Mistakes happen. I've seen plenty of cases where a missing hour or wrong rate meant someone was owed hundreds of dollars.
