How this overtime calculator works
Under the federal Fair Labor Standards Act (FLSA), a non-exempt employee must be paid at least one and a half times the regular rate for hours worked over 40 in a workweek. A workweek is a fixed, repeating period of 168 hours, and each workweek stands alone. Federal law does not set a daily limit, and it does not require overtime for weekend or holiday work as such.
If you are paid every two weeks, the Biweekly Timesheet Calculator checks each workweek on its own. Some states and employers add their own rules, such as overtime after a set number of hours in a day. The Daily shifts tab lets you enter those rules. California has a longer set of rules, so it has its own page: the California Overtime Calculator. For the formula in plain steps, read How to Calculate Overtime.
Three steps
- Enter your total hours for the week, or switch to Daily shifts and enter each day.
- Set the overtime rules your employer or state uses. The defaults are 40 hours and 1.5 times.
- Read regular hours, overtime hours and pay, and open the working to check each line.
Worked examples
50 hours in a week at $20.00 an hour: the first 40 hours at $20.00 is $800.00, and the 10 overtime hours at $30.00 is $300.00, so the total is $1,100.00.
On the Daily shifts tab with daily overtime after 8 hours and double time after 12 hours, a Monday of 13:00 paid time comes out as 8:00 regular, 4:00 at 1.5 times and 1:00 at 2 times. Use Fill example on either tab to load these.
| Entry | Regular | Overtime | Total pay |
|---|---|---|---|
| 50 hours in the week | 40:00, $800.00 | 10:00, $300.00 | $1,100.00 |
| 45 hours in the week | 40:00, $800.00 | 5:00, $150.00 | $950.00 |
Questions people ask
How do you calculate overtime pay?
Multiply your regular hourly rate by 1.5 to get the overtime rate, then multiply that by your overtime hours. Add the pay for your regular hours. At $20.00 an hour with 50 hours worked, regular pay is 40 x $20.00 = $800.00 and overtime pay is 10 x $30.00 = $300.00, for $1,100.00 in all.
How is overtime calculated for 45 hours?
45 hours in a workweek has 5 overtime hours, because everything over 40 is overtime. At $20.00 an hour that is 40 x $20.00 = $800.00 plus 5 x $30.00 = $150.00, which is $950.00.
What does time and a half mean?
It means you are paid 1.5 times your regular rate for those hours. At $20.00 an hour, time and a half is $30.00 an hour. The Time and a Half Calculator starts from a rate and shows the pay.
Is overtime calculated daily or weekly?
Federal law counts it weekly: hours over 40 in a workweek. It has no daily threshold. Some states, California among them, and some employers also count hours over a set number in a single day. Use the Daily shifts tab to apply a daily rule, and see the California page for that state's rules.
Does an unpaid lunch count toward overtime?
No. A real meal period, usually 30 minutes or more with the worker fully relieved of duty, is not work time, so it does not count toward the 40 hours. Short rest breaks of about 5 to 20 minutes are paid and do count. See 29 CFR 785.19 and the Department of Labor's breaks page.
What counts as the regular rate of pay?
It is not always your base hourly rate. The regular rate includes all pay for the work except certain payments the law excludes, such as discretionary bonuses. If you get that kind of pay, your regular rate can be higher than your base rate, and so can your overtime pay. Fact Sheet #23 explains how it is figured.
Do salaried employees get overtime?
It depends on whether the employee is exempt, which turns on the job duties and the pay, and being paid a salary does not decide it by itself. This calculator does not decide exempt status and does not state any salary threshold. Check Fact Sheet #23 and your state labor department for the current rules.
About this calculator
The rules here are the federal ones, plus the daily options you set yourself. The weekly rule comes from the Department of Labor's Fact Sheet #23: hours over 40 in a fixed 168 hour workweek are paid at one and a half times the regular rate, with no averaging across weeks. Daily overtime, double time and premium days are options you set, not federal law, and the page says so wherever they appear.
I tested the calculator with named cases before publishing: 50 hours at $20.00, 45:30 hours at $18.50, and a 13 hour Monday with daily overtime after 8 hours and double time after 12. The page links its source so you can check the current rule yourself, and I update the calculator if that source changes.

This calculator gives estimates for checking and planning pay. It is not legal, tax or payroll advice. Your employer's pay policy, your contract and the law where you work decide what you are owed. Overtime rules apply to non-exempt employees. This tool does not decide whether you are exempt.
