Most overtime calculators assume the federal rule and stop there. This one asks what rule you are working under. Enter a pay rate and the hours worked, set the weekly or daily threshold and the multiplier, and it works out regular pay, overtime at time and a half or double time, and the gross for the period as you type. Then download the result as a PDF, Excel, or CSV file. Everything runs in your browser, so your figures never leave your computer.
The blended regular rate is the straight-time pay at every rate added together, divided by the total hours. Overtime and double time are paid at their multiplier times that blended rate. Up to 3 rates. The hours here should add up to the hours in step 2.
The same blended rate is applied to every workweek in the period. If the mix of rates changed from one week to the next, run each week on its own.
Overtime is always computed per workweek, never across the whole pay period. A 50 hour week followed by a 30 hour week has 10 overtime hours, even though the two weeks average 40.
A semimonthly period does not line up with workweeks. Enter each workweek you are paying in this period. Overtime is still worked out one workweek at a time, and how to split a week that straddles two periods is a payroll decision this tool does not make.
A preset only fills in the fields below. Every number stays editable, and changing any of them clears the preset name. Picking a preset is not a finding that its rule applies to you.
Each workweek is counted both ways, by day and by week, and the count that gives the larger overtime total is used. The result says which rule was applied. No hour is ever counted as both daily and weekly overtime. Double time hours are taken out first and are not counted again as overtime.
Stacking. Daily overtime and double time come out of each day first. Weekly overtime then applies only to the regular hours that are left, above the weekly threshold, so no hour is ever paid twice. California is the common example of a stacking state. This tool does not decide which state’s rule applies to you.
How this tool treats the seventh consecutive day. With the box ticked, the seventh day counts only when hours are entered on all seven days of the same workweek, so it is always the last day of that workweek. Nothing carries over from the previous workweek, and a day left blank or at 0 breaks the run. On the seventh day, every hour up to the daily threshold is overtime at the daily multiplier, and every hour past it is paid at the double time multiplier, whatever the double time threshold is set to. If double time is switched off, those hours stay at the daily multiplier. Every seventh day hour is already a premium hour, so none of them count toward weekly overtime. Untick the box to treat the seventh day like any other day.
Weekly only. Only hours over the weekly threshold are overtime. The daily threshold, double time, and the seventh day are ignored entirely.
Names, rates, and hours stay on your computer. This tool runs entirely in your browser. Rates and hours are processed on your own device and never reach GlassJar, and neither does any name you enter.
This tool does arithmetic on the overtime rule you give it. It does not decide whether overtime is owed, how a worker is classified, or what any state requires. Rules vary by state and by classification. See the full Tool Notice and Terms of Use.
How to calculate overtime pay
Under federal law, overtime is owed after 40 hours in a workweek, at one and a half times the regular rate of pay. The calculation runs in three steps. Count the hours above the threshold. Multiply the base rate by the multiplier to get the overtime rate. Pay the regular hours at the base rate and the overtime hours at the overtime rate, then add the two together.
A worked example. Someone paid 24.00 dollars an hour works 46 hours in a week. The first 40 hours come to 960.00 dollars. The six overtime hours are paid at 36.00 dollars, which is 216.00 dollars. Gross pay for the week is 1,176.00 dollars. That is the whole method, and the calculator above shows each line so you can check it against a payslip.
Time and a half, and what it comes to
Time and a half means the base rate plus half of it again, which is the same as multiplying by 1.5. At 20.00 dollars an hour, time and a half is 30.00 dollars. At 18.50 dollars it is 27.75 dollars. At 31.20 dollars it is 46.80 dollars.
The calculator prints the overtime rate as a figure rather than leaving it implied, because that is the number people want to sanity check. When the multiplier is 1.5 it labels the line as time and a half. Change the multiplier and the label and the arithmetic change with it.
Double time, and the seventh day in a row
Double time is twice the base rate. Federal law does not require it at any point. It comes from a state rule or from a contract, so whether it applies to you depends on where the work happens and what was agreed.
California is the common example. Hours past 12 in a single day are paid at double time, and on a seventh consecutive day in the same workweek the first 8 hours are overtime with anything beyond that at double time. The calculator has a double time threshold and multiplier you can set yourself, and a seventh day option when the stacking mode is on.
Daily overtime, weekly overtime, and the states that stack them
The federal rule counts a week. Several states also count a day, so a 10 hour Tuesday can earn overtime even in a week that never reaches 40 hours. Alaska, California, Colorado and Nevada all have daily thresholds, and the details differ between them.
That leaves the question of what happens when both rules could apply to the same week. This tool offers three answers. Larger of the two counts the week both ways and uses whichever produces more overtime. Stack them, which is how California works, takes the daily overtime out first and then applies the weekly rule to the regular hours that are left, so no hour is ever paid twice. Weekly only ignores the daily threshold altogether.
Which one is correct for you is a question about your state and the work being done, and this tool does not answer it. Your state labor agency publishes its own rule, and a qualified professional can tell you how it applies to a specific person.
Salaried people, and more than one pay rate
A salaried worker who is entitled to overtime still needs an hourly figure before the overtime rate exists. Switch the tool to salary and enter the annual amount and the hours the salary is meant to cover. It divides out to an hourly rate and uses that. Being paid a salary is not by itself what makes someone exempt, which is a separate test.
When someone works at two or three different rates in the same week, federal law prices their overtime from the weighted average of those rates rather than from whichever rate they happened to be on. The blended rate option takes the hours at each rate and works the average out for you.
If you are starting from clock in and clock out times
This page takes hours as numbers. If what you have is a week of clock times and unpaid breaks, start with the timesheet calculator instead. It turns the times into hours, applies the same kind of overtime rule, and prices the period for one person or a whole crew. Both tools are part of the free business calculators set.
What this tool does not decide
It does arithmetic on the rule you give it. It does not decide whether overtime is owed, whether a worker is exempt or non exempt, how someone should be classified, which state rule applies, or whether a bonus has to be rolled into the regular rate before the overtime rate is worked out. Those are questions for a qualified professional or your state labor agency. The details of what the tool does with your figures are in the tool notice.
Frequently Asked Questions
How do I calculate overtime pay?
Count the hours above your overtime threshold, multiply the base hourly rate by the overtime multiplier to get the overtime rate, then pay the regular hours at the base rate and the overtime hours at the overtime rate. At 24.00 dollars an hour with a 40 hour threshold and a 1.5 multiplier, a 46 hour week is 960.00 dollars of regular pay plus 216.00 dollars of overtime, so 1,176.00 dollars in total.
How much is time and a half?
Time and a half is 1.5 times the base hourly rate. At 15.00 dollars an hour it is 22.50 dollars, at 20.00 dollars it is 30.00 dollars, and at 25.00 dollars it is 37.50 dollars. The calculator shows the figure for whatever rate you enter.
Is overtime based on 40 hours a week or 8 hours a day?
Federal law counts the week and owes overtime after 40 hours. Some states, including Alaska, California, Colorado and Nevada, also count the day. This tool lets you set a weekly threshold, a daily threshold, or both, and choose how the two combine.
Does this handle double time?
Yes. Turn on double time and set the threshold and the multiplier. The default is hours past 12 in a day at twice the base rate, which follows the California pattern, and every number can be changed.
How does overtime work for a salaried employee?
If the person is entitled to overtime, their salary is converted to an hourly rate first, and the overtime rate comes from that. Switch the tool to salary and enter the annual figure and the hours it covers. Whether a salaried person is entitled to overtime at all is a separate classification question that this tool does not answer.
What if someone works at two different pay rates in the same week?
Federal law prices the overtime from the weighted average of the rates worked that week. Use the blended rate option, enter the hours at each rate, and the tool works out the average and uses it for the overtime premium.
Does anything I type get sent to GlassJar?
No. The rates, hours and names you enter are processed on your own device and are never transmitted to us. If you choose to download a file, the email address you give is all we receive.
