Overtime only feels worth it when you know exactly what those extra hours pay. The problem is that most payslips show one total figure, with the overtime part buried inside it. A time and a half calculator separates the numbers for you: enter your hourly rate and your overtime hours, and it shows your overtime rate, the pay for those extra hours, and the premium you earned on top of your normal wage.
Time and a half simply means 1.5 times your regular hourly rate. If you earn $20 an hour, your time and a half rate is $30 an hour. Simple in theory, but what counts as your regular rate, when overtime legally starts, and how a salary converts to an hourly figure all change the final answer. This page explains the calculator, the formula behind it, and the US rules that decide who qualifies, with worked examples you can check against your own payslip.

What Is Time and a Half?
Time and a half is a pay rate of one and a half times an employee’s regular hourly rate, and it is the standard overtime rate in the United States. The “half” is the key part: for every overtime hour, you get your full normal rate plus an extra 50% on top. That extra 50% is called the overtime premium.
For example, if your regular rate is $18 an hour, your time and a half rate is $27 an hour. Ten overtime hours at that rate pay $270, of which $180 is what those hours would have paid at straight time, and $90 is the premium, the actual reward for working beyond your normal schedule.
Time and a half most commonly applies to hours worked beyond 40 in a single workweek, and can also appear in contracts and company policies for weekends, holidays, or night shifts.
How to Use the Time and a Half Calculator
The calculator needs only a few inputs:
- Enter your regular hourly rate. If you are salaried, use the salary conversion method explained further down this page first.
- Enter your overtime hours. Count only the hours that qualify for the overtime rate, usually the hours beyond 40 in the workweek.
- Check the multiplier. The default is 1.5. Keep it there unless your employer pays a different premium.
- Read your results. You will see your overtime hourly rate, the total overtime pay, and the premium portion on its own.
Add your regular pay (hourly rate x regular hours) to the overtime figure to get your total gross pay for the week. If you track start and finish times, a work hours calculator helps you confirm the hours themselves before you price them.
The Time and a Half Formula
Every overtime calculator is built on three short steps:
- Overtime rate = Regular hourly rate x 1.5
- Overtime pay = Overtime rate x Overtime hours
- Total weekly pay = (Regular rate x 40) + Overtime pay
As a single formula:
Time and a Half Pay = Hourly Rate x 1.5 x Overtime Hours
And the premium on its own, the extra money above straight time, is:
Overtime Premium = Hourly Rate x 0.5 x Overtime Hours
That second formula matters because some payslips list only the 0.5 premium as overtime, with the straight-time portion of those hours already counted inside your regular pay. If your overtime figure looks smaller than expected, check that first, it is a common payroll layout, not necessarily an error.
Time and a Half Chart for Common Hourly Rates
Use this table for a quick answer without calculating. It shows the time and a half rate for common US hourly wages, and what 5 and 10 overtime hours pay at each rate.
| Hourly Rate | Time and a Half Rate | Double Time Rate | Pay for 5 OT Hours | Pay for 10 OT Hours |
|---|---|---|---|---|
| $10.00 | $15.00 | $20.00 | $75.00 | $150.00 |
| $12.00 | $18.00 | $24.00 | $90.00 | $180.00 |
| $15.00 | $22.50 | $30.00 | $112.50 | $225.00 |
| $18.00 | $27.00 | $36.00 | $135.00 | $270.00 |
| $20.00 | $30.00 | $40.00 | $150.00 | $300.00 |
| $25.00 | $37.50 | $50.00 | $187.50 | $375.00 |
| $30.00 | $45.00 | $60.00 | $225.00 | $450.00 |
| $35.00 | $52.50 | $70.00 | $262.50 | $525.00 |
| $40.00 | $60.00 | $80.00 | $300.00 | $600.00 |
| $50.00 | $75.00 | $100.00 | $375.00 | $750.00 |
Notice the pattern: a $2 pay rise lifts your overtime rate by $3, because the rate rises by one and a half times the raise.
Worked Example: A Step-by-Step Calculation
Maria earns $22 an hour as a warehouse associate. One week she works 46 hours.
- Overtime hours: 46 – 40 = 6 hours.
- Time and a half rate: $22.00 x 1.5 = $33.00 per overtime hour.
- Regular pay: 40 x $22.00 = $880.00.
- Overtime pay: 6 x $33.00 = $198.00.
- Total gross pay: $880.00 + $198.00 = $1,078.00.
| Pay Element | Calculation | Amount |
|---|---|---|
| Regular pay (40 hours) | 40 x $22.00 | $880.00 |
| Overtime pay (6 hours at 1.5x) | 6 x $33.00 | $198.00 |
| Total gross pay | $880.00 + $198.00 | $1,078.00 |
| Pay if all 46 hours were straight time | 46 x $22.00 | $1,012.00 |
| Overtime premium earned | $1,078.00 – $1,012.00 | $66.00 |
The last line is the one many people miss: compared with straight time for the same hours, the true bonus for the extra effort is the $66 premium.
Who Gets Time and a Half? The US Rules
In the United States, time and a half is set by the Fair Labor Standards Act (FLSA). Covered, nonexempt employees must receive overtime pay at not less than one and a half times their regular rate of pay for hours worked over 40 in a workweek, according to the U.S. Department of Labor. Five points decide how the rule applies to you:
- Nonexempt vs exempt. Overtime rights apply to nonexempt employees. Bona fide executive, administrative, and professional employees who meet the FLSA duties and salary tests are exempt, which is why many salaried managers receive no overtime.
- The workweek is fixed. A workweek is a fixed, regularly recurring period of 168 hours (seven consecutive 24-hour periods). Overtime is calculated per workweek; an employer cannot average hours across two weeks to avoid paying it.
- The regular rate is broader than your wage. It generally includes shift differentials and nondiscretionary bonuses, not just base hourly pay. The Department of Labor’s Fact Sheet #23 on FLSA overtime pay explains how the regular rate is worked out.
- State rules can pay more. Some states add daily overtime rules, California is the best-known example. Where state and federal law both apply, the employee gets whichever standard pays more.
- Weekends and holidays are not automatic. Federal law does not require time and a half simply because work falls on a Saturday, Sunday, or holiday. Premium pay for those days is a matter of agreement, unless the hours push the workweek past 40.
This calculator gives an estimate, not a legal ruling, if your classification is in question, your contract and state labor office are the authority.
Time and a Half vs Double Time
Double time is the next step up: twice the regular rate. It is far less common, and unlike time and a half it is generally not required by federal law.
| Feature | Time and a Half | Double Time |
|---|---|---|
| Multiplier | 1.5x regular rate | 2x regular rate |
| Rate on $20/hour | $30/hour | $40/hour |
| Premium over straight time | +50% | +100% |
| Required by FLSA after 40 hours/week | Yes, for nonexempt employees | No |
| Typical triggers | Weekly overtime over 40 hours | Holidays, Sundays, very long shifts, some state daily-overtime rules and contracts |
Employers sometimes pay double time voluntarily for holiday shifts or under a union agreement. To model it in the calculator, simply change the multiplier from 1.5 to 2.
How to Calculate Time and a Half on a Salary
Salaried nonexempt employees are still entitled to overtime in the US, but you need an hourly figure first. Under the FLSA method, the regular rate is your total pay for the workweek divided by the total hours you actually worked that week.
Example: James is paid $900 for a week in which he works 45 hours, and the salary covers straight-time pay for all 45 hours.
- Regular rate: $900 / 45 = $20.00 per hour.
- Premium owed: The salary already covers straight time, so he is owed the extra half rate on the 5 overtime hours: $20.00 x 0.5 x 5 = $50.00.
- Total pay: $900 + $50 = $950.00.
If a salary is instead agreed for a fixed 40-hour week, divide it by 40 for the regular rate and pay hours beyond 40 at the full 1.5x rate, the two methods differ, so your agreement matters. A pay raise calculator can help you compare a new offer in hourly terms.
Common Mistakes to Avoid
Most wrong overtime figures come from a few repeat errors:
- Using the base wage instead of the regular rate. Bonuses and shift differentials usually count toward the regular rate; ignoring them understates overtime pay.
- Averaging two weeks together. A 50-hour week followed by a 30-hour week is not a 40/40 split, the first week still contains 10 overtime hours.
- Assuming weekends automatically pay 1.5x. Under federal law they do not, unless the hours pass 40 in the week or your contract promises it.
- Missing the premium-only payslip layout. If overtime pay looks low, check whether the straight-time part of those hours sits inside your regular pay line.
- Counting unpaid breaks as hours worked. Only hours actually worked count toward the 40-hour threshold. A time card calculator can help you verify hours before pricing them.
- Ignoring state law. Daily overtime states can produce a higher figure than the federal weekly rule alone.
Gross Pay vs Take-Home Pay
Everything this calculator shows is gross pay, before deductions. Overtime is taxed like any other wages, federal income tax, Social Security, and Medicare all apply. A bigger paycheck can have more tax withheld that pay period, because withholding assumes that pace of earnings continues all year; that is a withholding effect, not a special overtime tax rate, and it balances out across the year.
For the after-tax picture in your state, compare your gross figure with a paycheck estimate such as our New Jersey paycheck calculator.
Conclusion
Time and a half is a simple idea, 1.5 times your regular rate for qualifying overtime hours, but the right answer depends on using the correct regular rate, the correct hours, and the rules that apply in your state. Use the calculator at the top of this page for an instant figure, check it against the rate chart and worked example, then compare it with your payslip line by line. If the numbers do not match, you now have the formula and the premium breakdown you need to ask payroll a precise question instead of a general one.
FAQs
How do I calculate time and a half for $20 an hour?
Multiply the hourly rate by 1.5: $20 x 1.5 = $30 an hour. Eight overtime hours at that rate pay 8 x $30 = $240, on top of your regular pay.
What is time and a half for $25 an hour?
$25 x 1.5 = $37.50 an hour. Five overtime hours pay $187.50, and ten pay $375. The rate chart on this page covers other common wages.
Is time and a half mandatory in the United States?
For covered, nonexempt employees, yes. The FLSA requires overtime pay of at least one and a half times the regular rate for hours over 40 in a workweek. Exempt employees, such as many executive, administrative, and professional staff who meet the FLSA tests, are not covered by this requirement.
Does time and a half apply to weekends and holidays?
Not automatically under federal law. Weekend and holiday hours only trigger time and a half if they take your week past 40 hours, if a state law requires it, or if your contract or company policy promises premium pay for them.
How many hours is overtime?
Under the FLSA, overtime starts after 40 hours worked in a single workweek. Some states, such as California, also have daily overtime rules that can trigger premium pay after 8 hours in a day. Hours cannot be averaged across two workweeks.
Is time and a half taxed differently from regular pay?
No. Overtime is taxed as ordinary wages at the same rates as regular pay. More tax may be withheld from a large overtime paycheck because withholding assumes that earnings pace continues, but overtime itself has no special higher tax rate.
