1Type in what each shop actually pays you — rate, hours, tools, commute. Then hit RUN THE NUMBERS.
2TRUE PAY = the money you actually keep after insurance, tools, commute, and 401k match.
3EFFECTIVE WAGE = true pay ÷ the hours you're really at the shop. This is the number that matters. A "$35/hr" flat rate can really be $18/hr once dead weeks and tool payments eat it.
4DEAD WEEKS = how many weeks a year the work dries up — rain, no cars in the bay, waiting on parts. Flat-rate guys live and die by this. Every other calculator ignores it.
