How Is Time-and-a-Half Calculated? Formula and Examples

The U.S. Department of Labor says the Fair Labor Standards Act (FLSA) requires covered, nonexempt employees to get overtime pay of at least one and one-half times their regular rate for every hour worked over 40 in a workweek. That sounds simple. In practice, it is one of the easiest places for payroll to go wrong.

The math is not the hard part. The hard part is knowing which pay counts toward the “regular rate,” which hours count as overtime, and when the workweek starts and ends. This guide walks you through the formula, then through real examples with bonuses, shift differentials, two pay rates, salaries, piece rates, and tipped workers.

What Does Time-and-a-Half Mean?

Time-and-a-half is the common name for the federal overtime rate. It means you pay 1.5 times an employee’s regular hourly rate for each overtime hour.

A few points shape how it works:

• It applies to nonexempt employees. Exempt employees, such as many salaried managers and professionals, are not owed overtime under the FLSA.
• It starts after 40 hours in one workweek. Federal law does not require overtime for hours over 8 in a day, for weekends, or for holidays.
• It is based on the regular rate, which is not always the same as the base hourly wage.
• It is a minimum. Some states set stricter rules, and some employers pay more than the law requires.

If you are still sorting out who is exempt and who is not, start there first. Overtime only applies once you have classified each role correctly.

How Do You Calculate Time-and-a-Half Step by Step?

For a simple hourly employee with no bonuses or extra pay, the calculation takes four steps:

1. Add up the hours worked in the workweek.
2. Subtract 40 to find the overtime hours.
3. Multiply the hourly rate by 1.5 to find the overtime rate.
4. Pay 40 hours at the regular rate, plus the overtime hours at the overtime rate.

Here is an example. Maria earns $22.50 an hour and works 48 hours in one workweek.

• Regular pay: 40 hours x $22.50 = $900.00
• Overtime rate: $22.50 x 1.5 = $33.75
• Overtime pay: 8 hours x $33.75 = $270.00
• Total gross pay: $900.00 + $270.00 = $1,170.00

You can also reach the same total another way. Pay all 48 hours at $22.50 ($1,080.00), then add a half-time premium of $11.25 for each of the 8 overtime hours ($90.00). The total is still $1,170.00. This second method matters later, because it is the method you need when the regular rate includes more than the hourly wage.

Round only at the end, and round to the cent. Rounding the overtime rate too early can leave you a few cents short on every paycheck, and those cents add up across a large team.

What Is the Regular Rate and Why Does It Matter?

The regular rate is the average hourly pay the employee earned for the week. You find it by dividing total pay for the workweek by total hours worked. Total pay includes the hourly wage and most other forms of pay tied to the work.

This is where many errors start. Employers often multiply the base wage by 1.5 and stop there. If the employee also earned a shift differential, a production bonus, or a commission, that shortcut underpays overtime.

Pay that usually belongs in the regular rate includes:

• Hourly wages and piece-rate earnings
• Shift differentials and hazard pay
• Commissions
• Nondiscretionary bonuses, such as attendance, productivity, and retention bonuses promised in advance

Pay that generally stays out includes truly discretionary bonuses, gifts, expense reimbursements, and pay for time not worked, such as vacation or sick leave. The Department of Labor explains the bonus rules in Fact Sheet #56C. A bonus is discretionary only if the employer decides both whether to pay it and how much to pay it, and does so at or near the end of the period, without any earlier promise. If you announced the bonus in advance, treat it as part of the regular rate.

Example: Shift Differential and a Flat Bonus

Devon earns $19 an hour. He works 44 hours in the week. He also earns a $2 per hour night differential for 20 of those hours and a $60 attendance bonus that was promised in advance.

• Hourly pay: 44 hours x $19 = $836.00
• Night differential: 20 hours x $2 = $40.00
• Attendance bonus: $60.00
• Total straight-time pay: $936.00
• Regular rate: $936.00 / 44 hours = $21.27 (rounded)
• Half-time premium: 4 overtime hours x ($21.27 x 0.5) = about $42.55
• Total gross pay: $936.00 + $42.55 = about $978.55

Notice that you do not multiply the full $936.00 by 1.5. The employee already received straight-time pay for all 44 hours. You only owe the extra half for the 4 overtime hours.

Example: A Quarterly Nondiscretionary Bonus

A bonus paid for more than one workweek has to be spread back over the weeks in which it was earned. Say Priya earns $20 an hour and receives a $1,300 productivity bonus for a 13-week quarter. That adds $100 to each week ($1,300 / 13).

In a week when she works 45 hours:

• Hourly pay: 45 hours x $20 = $900.00
• Weekly share of the bonus: $100.00
• Total straight-time pay: $1,000.00
• Regular rate: $1,000.00 / 45 hours = $22.22 (rounded)
• Half-time premium: 5 overtime hours x ($22.22 x 0.5) = about $55.56
• Added pay for that week: about $55.56

You would owe that extra amount for each week in the quarter in which she worked overtime, and you would pay it when the bonus is paid or soon after.

Example: Two Pay Rates in One Week

When an employee works two jobs for you at different rates, you can use a weighted average. Sam works 30 hours as a cashier at $15 an hour and 18 hours on the stockroom crew at $21 an hour.

• Cashier pay: 30 x $15 = $450.00
• Stockroom pay: 18 x $21 = $378.00
• Total straight-time pay: $828.00 for 48 hours
• Regular rate: $828.00 / 48 hours = $17.25
• Half-time premium: 8 overtime hours x ($17.25 x 0.5) = $69.00
• Total gross pay: $828.00 + $69.00 = $897.00

This is common in retail and hospitality, where one person may cover the floor, the kitchen, and the front desk in the same week. Track hours by role, or the weighted average becomes a guess.

How Do You Calculate Time-and-a-Half for Salaried Nonexempt Employees?

A salary does not make someone exempt. If an employee does not meet the duties and pay tests for an exemption, you still owe overtime, even when you pay them a fixed amount each week.

The usual approach starts by working out the hourly rate the salary is meant to cover. Suppose an employee earns $1,000 a week for a regular 40-hour schedule:

• Regular rate: $1,000 / 40 hours = $25.00
• Overtime rate: $25.00 x 1.5 = $37.50
• Pay for 5 overtime hours: 5 x $37.50 = $187.50
• Total gross pay: $1,000.00 + $187.50 = $1,187.50

There is a second method, called the fluctuating workweek method. It can apply when the employee’s hours change from week to week and you and the employee clearly agree that the fixed salary covers all hours worked. Under this method, the regular rate is the salary divided by all hours worked that week, and you pay only an extra half-time premium. If the same employee works 50 hours for a $1,000 salary, the regular rate is $20.00 ($1,000 / 50). The premium is 10 overtime hours x $10.00 (half of $20.00) = $100.00, for total pay of $1,100.00. Some states do not allow this method, and California is one of them. Check your state’s rules before you use it. If you want to learn more about how fixed pay works, see our guide on how salary pay works.

How Do You Calculate Time-and-a-Half for Piece-Rate and Tipped Employees?

Piece-Rate Workers

For piece-rate pay, add up all the piece-rate earnings for the week and divide by the total hours worked. That gives you the regular rate. Then pay an extra half of that rate for each overtime hour.

For example, a production worker makes 460 pieces at $1.20 each over 46 hours.

• Piece-rate earnings: 460 x $1.20 = $552.00
• Regular rate: $552.00 / 46 hours = $12.00
• Half-time premium: 6 overtime hours x $6.00 = $36.00
• Total gross pay: $552.00 + $36.00 = $588.00

This comes up often in manufacturing, where output pay and shift work can mix in the same paycheck.

Tipped Employees

Tips make overtime less obvious. Under federal law, overtime for a tipped employee is based on the full minimum wage, not on the lower cash wage. If you take a tip credit, you pay 1.5 times the full minimum wage and subtract the same tip credit you used for regular hours.

Using the federal numbers as an example, the minimum wage is $7.25, so the overtime rate is $10.875 ($7.25 x 1.5). With the maximum federal tip credit of $5.12, the cash wage you owe for each overtime hour is about $5.76. Many states set higher minimum wages and smaller tip credits, so the number you owe may be higher. The tips themselves are not part of the regular rate, but you still need to track and report them correctly. If you run a restaurant, this is also a good time to review how you choose a restaurant payroll provider.

When Does the Workweek Start, and Why Does It Matter?

Overtime is counted by the workweek, not by the pay period. A workweek is a fixed, repeating period of 168 hours, which is seven days in a row. You choose when it starts, and it can begin on any day and at any hour. Once you set it, you should keep it consistent.

The key point is that you cannot average hours across two weeks. Suppose an employee is paid every two weeks, earns $20 an hour, and works 50 hours in week one and 30 hours in week two. That is 80 hours in total, but it is not zero overtime. The 10 hours over 40 in week one are overtime.

• Week one: 40 x $20 = $800.00, plus 10 x $30.00 = $300.00, for $1,100.00
• Week two: 30 x $20 = $600.00
• Total gross pay: $1,700.00, not the $1,600.00 you would get from averaging

Some states also count overtime by the day. California, for example, requires time-and-a-half for hours over 8 in a day and double time for hours over 12 in a day. Alaska, Colorado, and Nevada also have daily overtime rules in some situations. Suppose a California employee earns $24 an hour and works 13 hours in one day:

• First 8 hours: 8 x $24 = $192.00
• Hours 9 to 12: 4 x $36.00 = $144.00
• Hour 13 at double time: 1 x $48.00 = $48.00
• Total for the day: $384.00

If you pay employees in more than one state, daily rules can make one set of overtime settings wrong for another location. Our payroll compliance checklist is a good place to confirm the basics, and you can read it in the payroll compliance checklist.

How Is Overtime Taxed and Reported for 2026 and Later?

Overtime pay is taxed as regular wages. Federal income tax withholding, Social Security, and Medicare apply as they do for any other pay, and withholding rules did not change when the new overtime deduction began.

What changed is the reporting. Under the 2025 tax law, eligible employees can deduct part of their “qualified overtime compensation” on their federal return. According to the Journal of Accountancy’s August 2026 update on IRS guidance, employers report the full amount of qualified overtime in Box 12 of Form W-2 using code TT beginning with 2026 forms. The deduction itself only applies to the premium portion, which is the extra half in time-and-a-half. It is capped at $12,500 per year ($25,000 for joint filers) and phases out for higher earners, starting at $150,000 of modified adjusted gross income ($300,000 for joint filers). It is available for tax years 2025 through 2028.

This means your payroll system needs to separate overtime premium pay from regular pay. If it only records total wages, you will have trouble filling in Box 12 accurately at year end. Our guide to year-end payroll covers the other W-2 steps you need to complete.

What Are Common Time-and-a-Half Mistakes?

Most overtime problems come from a short list of habits. Watch for these:

• Using the base wage only. Leaving bonuses, differentials, and commissions out of the regular rate underpays overtime.
• Multiplying total pay by 1.5. If the employee already received straight-time pay for all hours, you only owe the extra half for the overtime hours.
• Averaging across weeks. Overtime is figured week by week, even when you pay every two weeks.
• Ignoring off-the-clock work. Time spent answering messages, setting up, or closing down counts when the employee is required or allowed to do it.
• Treating a salary as an exemption. Only meeting the duties and pay tests makes someone exempt.
• Using a flat overtime bonus. A fixed payment in place of overtime pay can fall short in heavy weeks.
• Changing the workweek to avoid overtime. Shifting the start day to split a busy stretch can create problems if it is done to avoid paying overtime.
• Paying late. Overtime is due on the regular payday for the period in which the workweek ends, in most cases.

The best defense is a clear process. Set the workweek, record the hours daily, and let your payroll system check each week for overtime before you approve a run.

How Can Payroll Software Help You Get Overtime Right?

Overtime errors are rarely about math. They happen when data is spread across timesheets, spreadsheets, and pay stubs, and nobody checks whether a bonus belongs in the regular rate. Good payroll software calculates the weighted regular rate, applies state daily rules, and keeps a clear record of how each number was reached. That record helps if an employee or an auditor asks questions later.

Hybrid Payroll offers HR and payroll software that connects time, pay, and compliance in one place. Teams in industries such as manufacturing and hospitality often juggle shifts, differentials, and multiple rates, so the right setup matters. Firms with a mix of exempt and nonexempt staff, such as processors, support teams, and branch employees, can also look at payroll software for financial services firms to keep overtime rules and classifications consistent.

Frequently Asked Questions

Do you have to pay time-and-a-half on weekends and holidays?

Not under federal law. The FLSA only requires overtime after 40 hours in a workweek, and weekend or holiday hours count toward that total like any other hours. Some employers choose to pay a premium for those days as a policy or because of a contract. Check your state law, because a few states have extra rules for certain industries or days of rest.

What is double time, and when do you have to pay it?

Double time means paying twice the regular rate. The FLSA does not require it. Some states, such as California, require it after 12 hours in a day or after 8 hours on the seventh straight day of work. Employers and union contracts may also set double time as a rule for holidays or long shifts.

Can you give comp time instead of overtime pay?

In most private businesses, no. Employers generally must pay overtime in cash. Comp time in place of overtime pay is mostly limited to public agencies. A private employer can sometimes balance hours inside a single workweek, such as giving time off on Friday to offset extra hours earlier in that same week, but the totals must stay at 40 or fewer.

Do you pay overtime if the employee did not get approval to work extra hours?

Yes. If you know or should know that the employee worked the time, you must pay for it. You can discipline an employee for breaking a no-overtime rule, but you cannot refuse to pay for the hours they already worked.

Does paid time off count toward the 40 hours?

Under federal law, hours paid but not worked, such as vacation, sick leave, and holidays, do not count toward the 40-hour overtime threshold. Some states, union contracts, or company policies treat them differently, so check what applies to you.

Do exempt employees ever get time-and-a-half?

Not under the FLSA, as long as they truly meet an exemption. An employer can still choose to pay overtime to exempt staff, and some state rules and contracts may require it. If the job duties or pay do not meet the tests, the employee is nonexempt and overtime is due.

How long do you have to keep overtime records?

The FLSA requires you to keep payroll records, such as hours worked and pay rates, for at least three years. Time cards and wage computation records must be kept for at least two years. Some states require longer periods, so check your state rules.

What happens if you underpay overtime?

You may owe the unpaid wages, usually for the past two years, or three years if the violation was willful. You may also owe an equal amount as liquidated damages, which can double the bill, plus attorney fees. Fixing mistakes quickly and keeping clear records lowers the risk.

Conclusion

Time-and-a-half is simple on paper: 1.5 times the regular rate for hours over 40 in a workweek. The details are where the risk sits. Build the regular rate from all eligible pay, count overtime week by week, follow your state’s daily rules, and track overtime premiums for year-end reporting. With a clear process and the right payroll tools, you can pay overtime correctly every time.
