In short

Repair order gross profit is the RO's sales minus what the work cost you: tech pay for the labor, parts cost and sublet cost. Gross profit percent is that profit divided by the sale. An $895 RO with $350 of cost makes $545, or 60.9%. Work it out per category, because labor and parts margins differ widely.

FAQ

Questions about the repair order gross profit calculator

How do you calculate gross profit on a repair order?
Add up the RO's sales (labor, parts, sublet, fees, without tax), subtract what each cost you (tech pay for the labor, parts and sublet cost), and divide the profit by the sales for GP%.
What counts as labor cost?
What you paid the technician for this job. For a flat-rate tech that's usually their rate times the hours flagged; for an hourly tech, their rate times the time on the job. Some shops add payroll taxes and benefits as a burden percentage.
Is gross profit the same as net profit?
No. Gross profit is before overhead such as rent, service writer pay, insurance and utilities. Net profit is what's left after those.
What is a good gross profit percent on a repair order?
It depends on your labor-to-parts mix, pay plan and market, so there's no single target. Track your own average over time and look at labor and parts separately.
Should shop supplies fees count?
Yes, as their own line, with whatever they really cost you. Check your state's rules on how fees must be shown on the invoice.
