The floor is not the market rate
Most shops inherit their hourly rate: the old owner's number, a competitor's sticker, what feels defensible on the phone. None of those know your costs. The floor is different: it is the number an hour of your shop must earn before the shop makes anything at all. It comes from arithmetic you can do in an evening, and once you have it, every rate conversation changes: you are no longer guessing whether a price works, you are measuring it against your own floor.
The cost pile
People
Wages, and the payroll burden on top of wages: taxes, insurance, the costs of employing that never show on the pay stub.
The trucks
Payments, fuel, insurance, tires, the repairs. Each truck is a rolling monthly bill.
The shop
Rent, utilities, the shelf stock that waits to be used.
The coverage
Liability insurance, bonding, licenses: the cost of being allowed to do the work.
The office
Software, the phone, the bookkeeping, the person who answers.
The quiet costs
Tools that wear out, training, the bad debt you eventually write off.

Which costs belong in the pile before you divide?
Billable hours are fewer than paid hours
Here is where the arithmetic usually breaks. A tech's paid week is not a billable week. Drive time is paid and not billed. Quoting, supply runs, training, the callback done under warranty, the slow season. All paid, none billed. Count the hours a customer actually pays for, honestly, over a real year. The number is smaller than the calendar suggests, and it is the only honest denominator.
The division
The method is one line: the year's cost pile, divided by the year's honest billable hours, is the break-even hour. Work priced at that number earns the shop exactly nothing. It is the floor, not the goal. Decide the profit the company should earn on top (profit is not the owner's wages; those were in the pile) and add it. Then compare the result to what you charge today. The comparison is the whole point of the exercise, and for some shops it is the first honest look at why busy months still feel broke.

Why not divide the cost pile by the paid hours on the calendar?
Your inputs, not our benchmark
Notice what this lesson did not give you: a number. Any rate printed here would be someone else's shop. The method is the teachable part: your pile, your hours, your floor. The free calculators on this site run this arithmetic from your own payroll, truck, and overhead figures, so the answer that comes out is yours and defensible. Redo it when wages move or a truck joins the fleet; the floor is a living number.
