What is the Gross Pay Calculator?
Your paycheck isn't just hours times rate — overtime changes the math. This calculator splits your week into regular hours and overtime hours, applies your hourly rate to the regular portion and the overtime multiplier (usually 1.5, the classic "time and a half") to the extra hours, then totals your gross pay. It also shows your effective hourly rate across the whole week, which is the number that reflects what those long days really earned you per hour.
A line cook in Nashville working 40 regular hours plus 5 overtime hours at $18 an hour is the textbook case. Regular pay comes to $720, the 5 overtime hours at time-and-a-half ($27/hr) add $135, and gross pay totals $855 — with an effective rate of $19 per hour across all 45 hours. That effective-rate figure is surprisingly useful: it is the honest answer to "what do you make per hour?" when overtime is routine.
Gross pay is before taxes, Social Security, Medicare, and deductions — your take-home will be lower. Overtime rules also vary: some states require daily overtime beyond 8 hours, and some employers use double time. This tool handles the standard weekly model; check your state's labor rules for the rest.
With the pre-filled defaults — Regular Hours 40, Overtime Hours 5, Hourly Rate ($) 18, OT Multiplier 1.5 — the Gross Pay Calculator returns Regular Pay ($) 720.00, Overtime Pay ($) 135.00, Gross Pay ($) 855.00, Effective Hourly Rate ($) 19.0000. Change any input and those results update instantly, so you can see exactly how each number you enter moves the answer.
