Overtime Calculator

What this overtime calculator does

This overtime calculator gives a fast gross-pay estimate from the inputs most people know: hourly rate, regular hours, overtime hours, overtime multiplier, and any double-time hours. Use the default overtime pay mode when you already know your hours, or switch to time card mode when you need to calculate weekly hours from clock-in and clock-out times first.

The overtime calculator starts with a 1.5x multiplier because time and a half is common in U.S. federal overtime discussions for many covered nonexempt employees. It also supports 2x double time and custom multipliers because some users are comparing employer policies, union agreements, local rules, or special shift arrangements. It does not decide whether a specific rule applies to you.

The overtime calculator updates immediately and shows money with two decimal places. Use the pay period selector in overtime pay mode when you want to annualize overtime pay. Use time card mode for a weekly time card estimate that subtracts unpaid breaks, splits regular and overtime hours, and summarizes gross pay.

How to use the overtime calculator

Choose the mode that matches the information you have. Select Overtime pay if you already know regular hours, overtime hours, and any double-time hours. Select Time card if you only have daily start times, end times, and break minutes, and want the calculator to total the week before estimating overtime.

Start with your regular hourly rate before overtime. Enter the hours that are paid at your regular rate, then enter overtime hours separately. If some hours are paid at double time, place those in the double-time field instead of mixing them into regular overtime hours.

Select the overtime multiplier that matches the scenario you are estimating. For many simple estimates, 1.5x means the overtime rate is one and one-half times the regular hourly rate. If your workplace uses a different multiplier for a specific situation, select Custom multiplier and enter that number.

Use the result cards to compare the parts of gross pay. The effective hourly rate is total gross pay divided by all hours entered. That number can help you compare a week with overtime against a week without overtime, but this overtime calculator is still a gross-pay estimate before taxes, deductions, and payroll adjustments.

When to use this overtime calculator

Use this overtime calculator when you want a quick check before taking an extra shift, reviewing a schedule, or comparing a regular week with a longer week. It is built for simple planning questions where you know the hourly rate and need the pay breakdown in plain numbers.

The overtime calculator is also useful when you are checking a paycheck estimate against your own notes. It separates regular pay, overtime pay, double-time pay, and total gross pay so you can see which part of the total changed.

If you do not know the overtime hours yet, switch the overtime calculator to time card mode and enter daily clock times instead. That mode totals the week first, then applies the weekly threshold and overtime multiplier.

Overtime calculator formula

This is the standard gross-pay method used across the calculators on this site unless a page explains a different method. It is intentionally transparent: every result comes from the same few inputs, and each result card names the calculation it represents.

Actual payroll calculations can include more than the base hourly wage. Under some rules, the regular rate may need to account for nondiscretionary bonuses, commissions, shift differentials, multiple pay rates, or other compensation. Treat the formula as a practical estimate, not a complete payroll audit.

overtimeRate = regularHourlyRate x overtimeMultiplier
overtimePay = overtimeHours x overtimeRate
regularPay = regularHours x regularHourlyRate
doubleTimePay = doubleTimeHours x regularHourlyRate x 2
totalGrossPay = regularPay + overtimePay + doubleTimePay
effectiveHourlyRate = totalGrossPay / totalHoursWorked

Example overtime calculation

Suppose you earn $25 per hour, work 40 regular hours, and work 8 overtime hours at 1.5x. Your regular pay is $1,000.00. Your overtime rate is $37.50 per hour. Eight overtime hours add $300.00 in overtime pay, so estimated gross pay is $1,300.00 before taxes and deductions.

Time and a half explained

Time and a half means 1.5 times the regular hourly rate. If the regular hourly rate is $20, the time-and-a-half rate is $30. If the regular hourly rate is $32, the time-and-a-half rate is $48. The phrase describes the rate, not the number of hours.

For U.S. federal overtime, the Fair Labor Standards Act is often summarized as requiring many covered nonexempt employees to receive overtime pay at not less than one and one-half times the regular rate for hours worked over 40 in a workweek. That summary still leaves important questions about coverage, exemptions, the regular rate, and state or local rules.

Double time explained

Double time means 2x the regular hourly rate. A $25 hourly rate becomes a $50 double-time rate. Double time may appear in workplace policies, collective bargaining agreements, certain state rules, long-shift rules, holiday policies, or special scheduling arrangements.

Do not assume double time applies only because a shift feels difficult or occurs on a particular day. The calculator can estimate pay once you know the hours and multiplier, but it does not determine whether a double-time rule applies to your job or location.

Weekend and holiday overtime note

Under the FLSA, extra pay is not required simply because work is performed on Saturdays, Sundays, holidays, or regular rest days unless overtime hours are worked on those days. This point surprises many users because employer policies may still offer holiday premiums, weekend premiums, or shift differentials.

State laws, local rules, industry rules, union agreements, employment contracts, and company policies may provide different or additional benefits. If a weekend or holiday shift also pushes the weekly total above an overtime threshold, the overtime calculation may still matter.

U.S. overtime rule overview

For many U.S. federal overtime calculations, the workweek is the relevant weekly period. A workweek is a fixed and regularly recurring period of 168 hours, or seven consecutive 24-hour periods. Federal overtime is generally not averaged across two or more workweeks.

The regular rate can be more than a base hourly wage. Depending on the compensation arrangement, nondiscretionary bonuses, commissions, shift differentials, or other payments may affect the rate used for overtime. That is why payroll-specific questions often require official guidance or a qualified professional.
