Overtime Pay Calculator

How do I calculate overtime pay?

How it is calculated

Pay is split into a regular part and an overtime part. Regular = regular hours × hourly rate, Overtime = overtime hours × hourly rate × multiplier, and Total = Regular + Overtime. The multiplier is the factor on the base rate, for example 1.5 for time and a half and 2 for double time. All four inputs must be zero or more. The tool does not decide which hours count as overtime or which multiplier applies, because that depends on the country, the contract and sometimes the day worked; enter the figures your rules give. Results are shown in dollars and are gross amounts before tax, social contributions and other deductions.

Worked example

An employee works 40 regular hours and 6 overtime hours at 22 per hour, with a 1.5 multiplier. Regular pay: 40 × 22 = 880, shown as $880.00. Overtime rate: 22 × 1.5 = 33 per hour, so overtime pay is 6 × 33 = 198, shown as $198.00. Total gross pay: 880 + 198 = $1,078.00.

Common mistakes

  • Counting overtime hours inside the regular hours as well, which pays them twice. Enter 40 regular and 6 overtime, not 46 and 6.
  • Entering the multiplier as a percentage (150) instead of a factor (1.5), which makes the overtime 100 times too large.
  • Entering 0.5 as the multiplier for time and a half. The multiplier replaces the rate (1.5 times), it is not added on top; 0.5 would pay half the base rate.
  • Reading the total as take-home pay. It is gross, before tax and other deductions.
  • Using the wrong rate base. Some jobs compute overtime on a rate that includes shift bonuses, so the hourly rate may need to be a blended rate.

About this calculator

This calculator computes total pay by combining regular hours worked at the standard hourly rate with overtime hours paid at a higher rate, using an overtime multiplier — commonly 1.5x ("time and a half") or 2x ("double time") — applied on top of the base rate. Entering regular hours, overtime hours, the hourly rate and the applicable multiplier produces the full paycheck breakdown before any tax withholding.

Hourly employees use it to verify that a paycheck correctly reflects overtime worked, since payroll errors on overtime calculations are common and easy to miss without checking the math independently. Employers and small business owners use the same calculation when budgeting labor costs for a shift schedule that includes overtime, and job seekers evaluating an hourly role with expected overtime use it to estimate realistic take-home pay beyond the base hourly rate advertised.

    The tool takes a single multiplier, but many pay rules use tiers, such as time and a half for the first overtime hours and double time after that. In that case run it once per tier and add the totals yourself. With a rate of 20, 4 hours at 1.5 pay $120.00 and 2 hours at 2 pay $80.00, so $200.00 of overtime. Which tier rules would you like to see supported in one go?
