How to use the time and a half calculator
- Enter your regular hourly rate.
- Enter your regular hours and your overtime hours for the week.
- Choose time and a half, double time, double time and a half, or your own multiplier.
- Read the overtime rate and the pay line by line, then copy or print it.
- Switch the view to see a yearly estimate if every week looked the same.
How is time and a half calculated?
The overtime rate is your regular hourly rate times the multiplier, 1.5 for time and a half. Regular pay is the regular hours times the rate, and overtime pay is the overtime hours times the overtime rate. Gross pay is the two added together. The yearly view multiplies one week by 52. The calculator multiplies the rate you enter, so a bonus or differential that raises the regular rate has to be included in that rate first.
For example, at $20 an hour time and a half is $30.00 an hour. A week of 40 regular hours and 10 overtime hours pays $800.00 + $300.00 = $1,100.00, and the same 10 hours at double time would pay $400.00. The rate and hours are made up; yours come from what you type.
Who should use the time and a half calculator
- Hourly workers checking an overtime paycheck
- Managers and payroll staff pricing overtime for a week
- Anyone converting an hourly rate into time and a half or double time
Who should not use this
- Anyone whose pay includes bonuses or shift differentials; use the overtime rate adjustment calculator
- Employees in California who need daily and double-time rules; use the overtime calculator’s California option
- Anyone who needs taxes or take-home pay; this shows gross pay
Limitations
- It multiplies the rate you enter; it does not add bonuses or differentials to the regular rate.
- Gross pay only, before tax.
- It does not decide how many of your hours are overtime; that depends on the workweek and your state.
- Results are estimates, not legal, tax, payroll or financial advice.

How to calculate time and a half
Multiply your regular hourly rate by 1.5. At $20 an hour, time and a half is $20 × 1.5 = $30.00 an hour. Then multiply that overtime rate by the overtime hours. A week of 40 regular hours and 10 overtime hours at $20 pays $800.00 + $300.00 = $1,100.00.
What is time and a half for $15, $18 and $20 an hour?

When does federal law require time and a half?
The Fair Labor Standards Act requires covered, non-exempt employees to be paid at least one and one-half times their regular rate for hours worked over 40 in a workweek. The workweek is a fixed, recurring period of 168 hours, and each week is counted on its own: hours are not averaged over two weeks. Employees in executive, administrative, professional and some other exempt jobs are not covered by this rule, and being paid a salary does not by itself make someone exempt.
Some states add daily overtime. Alaska requires time and a half after 8 hours in a day as well as after 40 in a week. California adds double time after 12 hours in a day and for work over 8 hours on a seventh consecutive day. Nevada requires daily overtime after 8 hours only for employees paid under $18.00 an hour from July 1, 2026. This page applies the weekly federal rule; the overtime calculator has a California option, and the guide to overtime after 8 hours a day or 40 a week explains the state differences.
Overtime calculatorUse the overtime calculator for the California daily rules and the federal no-tax-on-overtime deduction.Double time and “double time and a half”
Double time is 2 times the regular rate, $40.00 at $20 an hour. “Double time and a half” most often means 2.5 times the rate, $50.00 at $20, but some people use the phrase for 2 times plus an extra half of something else, so confirm the multiplier in your pay policy. Federal law sets only the 1.5 minimum for overtime; double time comes from state law (such as California’s over-12-hours rule), a contract, a union agreement or an employer policy. Pick 2 or 2.5 in the calculator, or enter your own multiplier.
Time and a half on holidays
Federal law does not require time and a half for working a holiday. Employers that offer it do so by policy, contract or union agreement, and a holiday premium of 1.5 times or more can be credited against overtime owed. To work out pay for a holiday you worked, with the overtime effect, use the holiday pay calculator.
Holiday pay calculatorCalculate holiday pay, paid or worked, at time and a half or double time.Bonuses and shift differentials change the base rate
Time and a half is 1.5 times the regular rate of pay, and the regular rate is not always the hourly wage. Non-discretionary bonuses, commissions and shift differentials are included, so the true rate can be higher. At two hourly rates in one week it is the weighted average of both. A calculator that multiplies the base wage by 1.5 then underpays the overtime. The overtime rate adjustment calculator handles these cases.
Overtime rate adjustment calculatorWork out the regular rate with a bonus, a differential or two pay rates.Time and a half and taxes
Overtime is taxed like other wages: federal income tax withholding, Social Security and Medicare apply to it. A large overtime check can look heavily taxed because withholding is estimated from the pay period’s gross pay, but the tax is settled on your return. This calculator shows gross pay only. To see take-home pay for a change in gross, use the payroll adjustment calculator with taxes.
Payroll adjustment calculator with taxesSee what extra gross pay does to take-home pay.Common time and a half mistakes
Most overtime errors come from using the wrong base rate or the wrong hours. These are the ones to check first.
- Paying 1.5 times on all hours instead of only the hours over the threshold.
- Adding the overtime rate on top of straight-time pay for the same hours (the 1.5 already includes the straight time).
- Using the base wage when a bonus or differential raises the regular rate.
- Averaging hours over two weeks. Each workweek stands alone.
- Treating a salary as proof of exemption.
- Assuming every state follows the federal weekly rule.
When to ask a professional
If overtime was worked and not paid, or you are unsure whether a job is exempt, the Department of Labor’s Wage and Hour Division and your state labor department can tell you what applies. The Department of Labor also has an FLSA overtime calculator advisor to check a result against. Results here are estimates, not legal, tax, payroll or financial advice.
How much is overtime pay for $20 an hour?
Overtime pay for $20 an hour is $30.00 an hour at time and a half. Ten overtime hours add $300.00, and a week of 40 regular hours plus 10 overtime hours pays $1,100.00. Five overtime hours pay $150.00 on top of $800.00, for $950.00.
The same calculator works as an overtime rate calculator and a weekly overtime calculator: enter the rate and the week’s regular and overtime hours and it returns the overtime rate and the gross pay. Many people search for it as an OT calculator, and the arithmetic is the same.
