Show the math

Overtime pays the multiplier on top of the base rate; employer FICA (7.65%) sits above gross:

gross = hours × rate + OT hours × rate × multiplier

employer cost = gross × 1.0765

This estimates the employer side only, it does not withhold income tax or the employee FICA share. All math runs in your browser.

What this does

A payroll calculator estimates gross pay from hours and rate with overtime at a multiplier, plus the employer payroll tax and the total cost to employ.

How to use it

  1. Enter the hours and rate.
  2. Add overtime hours and multiplier.
  3. Read the gross pay.
  4. See the total employer cost.

How it works

Overtime is commonly 1.5×. This estimates the employer FICA share (Social Security plus Medicare) on top of gross — a quick ballpark, not exact withholding.

gross = (reg + OT × multiplier) × rate; + 7.65% employer FICA

Understanding your result

Gross pay is what the employee earns, but the total cost to employ is the number that hits your budget, because employer payroll tax sits on top. Use the total when planning headcount or quoting labour. This is a quick estimate, not exact withholding, which varies by location and filing details.

Example

40 hours at $25 is $1,000 gross, about $1,077 to employ.
