Overtime Pay Calculator

What this overtime pay calculator estimates

This page focuses on the pay created by overtime hours. It is different from a simple hours calculator because it separates regular pay, overtime rate, overtime earnings, and the overtime premium. That separation helps when you are checking a paycheck, comparing shifts, or explaining why overtime pay is higher than straight-time pay.

The calculator uses your regular hourly rate and overtime multiplier to find the overtime rate. It then multiplies that rate by overtime hours. If you also enter regular hours, the result shows total gross pay for the period before taxes and deductions.

The overtime premium is the part of overtime pay that is above regular straight-time pay. For example, at 1.5x, an overtime hour contains one regular hour of pay plus an additional half-hour premium. Looking at the premium can be useful when you want to understand the true extra value of working overtime instead of regular hours.

Method used for overtime pay

This calculator uses a gross-pay method. It does not withhold tax, estimate benefit deductions, or determine whether a particular overtime law applies. It is best for comparing pay scenarios after you already know which hours are regular and which hours should be treated as overtime.

Regular rate questions can be more complex than a single hourly rate. In some settings, nondiscretionary bonuses, commissions, and shift differentials may need to be considered. The calculator keeps the math transparent while the page links to official sources for deeper payroll questions.

overtimeRate = regularHourlyRate x overtimeMultiplier
overtimeEarnings = overtimeHours x overtimeRate
regularPay = regularHours x regularHourlyRate
overtimePremium = overtimeEarnings - (overtimeHours x regularHourlyRate)
totalGrossPay = regularPay + overtimeEarnings

Example using $20 per hour and 5 overtime hours

If your regular hourly rate is $20, 40 regular hours create $800 in regular pay. At a 1.5x overtime multiplier, the overtime rate is $30 per hour. Five overtime hours create $150 in overtime earnings. Total estimated gross pay is $950.

The overtime premium in that example is $50. That is because five hours paid at the regular $20 rate would be $100, while five hours at the $30 overtime rate are $150. The $50 difference is the extra premium created by the 1.5x multiplier.

When to use this calculator

Use this calculator when your main question is, How much extra gross pay will these overtime hours add? It is a good fit when you know the hourly rate, overtime hours, and multiplier, but you want the result broken into regular pay and overtime earnings.

For a full paycheck-style estimate with optional deductions, use the paycheck overtime calculator. For take-home overtime after estimated tax rates, use the overtime after tax calculator. If you do not know overtime hours yet, use the timesheet overtime calculator.

What this calculator does not cover

This tool does not decide eligibility, exemption status, or whether overtime is owed. Those questions may depend on federal, state, local, industry, union, and employer-specific rules. It also does not account for multiple rates of pay, retroactive adjustments, paid leave, daily overtime rules, or unusual payroll calendars.

It does not calculate net pay. Withholding can change when overtime increases gross earnings, and actual taxes depend on filing status, annual income, deductions, credits, state rules, payroll taxes, and other circumstances.

Common mistakes and limitations

A common mistake is entering total hours as overtime hours. If you worked 45 total hours and the applicable weekly threshold is 40, the overtime hours may be 5, not 45. Another common mistake is using the overtime rate as the regular hourly rate. Enter the regular hourly rate and let the calculator apply the multiplier.

Another limitation is assuming every premium is legally required. A workplace may pay shift differentials, weekend premiums, or holiday premiums under policy even when federal overtime is not triggered. Keep those categories separate when reviewing a pay stub.
