How this works

What the fee covers

Brake clean, penetrant, gloves, rags, zip ties, thread locker, fluid disposal. The stuff you use on a job but cannot bill as a part. If you can name it and price it as a part, it belongs on a part line instead.

Two honest ways to charge it

A flat amount per job, or a small percent of the labor with a dollar cap so a big job does not turn into a big supplies charge. This calculator works out both from your real monthly spend, so the fee is a number you can defend.

Check your state

Some states with auto repair laws (Florida and California are two) regulate how charges must appear on estimates and invoices. The safe habit everywhere: name the line "shop supplies", show it on the estimate the customer approves, and keep it reasonable.

Common questions

How much should I charge for shop supplies?

Enough to cover what you really spend. Add up a month of consumables, divide by the jobs you did, and that is your break-even fee per job.

How do I explain a shop supplies fee to a customer?

Say it plainly: "Shop supplies are the chemicals, gloves and disposal I go through on your job. It is on the estimate so you see it before you approve anything."

Is a shop supplies fee legal?

In most places yes, as long as it is shown on the estimate before the work and on the invoice. States with repair laws may have rules on how it is listed, so check yours.
