How to use the Overtime Pay Calculator
Use the calculator to estimate gross pay from the numbers you enter. It separates regular pay and overtime pay, then shows the formula and intermediate values after you click Calculate.
- Enter Base hourly rate ($/hour).
- Review or edit Overtime multiplier (x). It starts at
1.5. - Enter Regular hours (this period) and Overtime hours (this period). A blank hours field counts as zero.
- Click Calculate.
- To start over, click Reset. It clears the rate and hour fields, hides the result, and restores the multiplier to
1.5.
The 1.5 value is an editable starting point. Change it to match the pay policy or law that applies to you.
What the result shows
After a successful calculation, the result displays Total gross pay, Overtime pay, and Regular pay. It also shows the formula and a table containing the entered values, overtime hourly rate, intermediate pay amounts, and total.

How the calculation works
The calculator applies one multiplier to the overtime hours you enter:
Overtime hourly rate = base rate x multiplierRegular pay = base rate x regular hoursOvertime pay = overtime hourly rate x overtime hoursGross pay = regular pay + overtime pay
Calculations use the parsed numeric inputs. Displayed and exported money, hours, and multiplier values are formatted to two decimal places.
Input validation
Calculation stops when an input fails validation. The base rate must be greater than zero, the multiplier must be 1 or greater, and entered hours must be zero or greater. Blank hour fields count as zero, but at least one hours field must be greater than zero.
Examples of the displayed errors are Enter a base hourly rate greater than 0. and Enter regular hours, overtime hours, or both.
Scope and limitations
- The result is gross pay before tax withholding, benefit deductions, or other adjustments.
- The calculator does not fetch live wage records, timesheets, or payroll data.
- It does not detect weekly overtime thresholds or model daily overtime rules.
- It does not calculate a blended regular rate using bonuses, commissions, or shift differentials.
- It does not determine which multiplier or overtime method applies to your jurisdiction, employer, or employment classification.
- The editable
1.5default is a common US time-and-a-half context, not a determination of entitlement. Check the applicable policy or law for your situation.
Calculator input handling
The calculator script performs the calculation from the values entered on the page and does not submit those calculator inputs to a calculator endpoint. This describes the calculator script only; the page also loads sitewide analytics and includes a separate subscription form.
Frequently Asked Questions
How is overtime pay calculated?
Overtime pay is the base hourly rate multiplied by the overtime multiplier and the overtime hours entered. Regular pay is the base rate multiplied by regular hours. Gross pay is the sum of both.
What overtime multiplier should I use?
The calculator starts at 1.5, a common US time-and-a-half context. Employers, contracts, holidays, jurisdictions, and employment classifications may use different rules. Edit the field to match the policy or law that applies to you.
Does this calculator fetch my actual pay rate or timesheet data?
No. It uses only the base rate, regular hours, overtime hours, and multiplier you enter. It does not fetch live wage records, timesheets, or payroll data.
Does this include tax withholding or deductions?
No. The result is gross pay before tax withholding, benefit deductions, or other paycheck adjustments, so it cannot be used as a net-pay result.
Why might my actual overtime pay differ from this estimate?
Rules can vary by jurisdiction, industry, employer, and employment classification. Some methods use daily thresholds, different multipliers, or a regular rate that includes bonuses or shift differentials. This calculator uses one flat multiplier with the rate and hours you enter.
