Auto repair shop revenue calculator car count × ARO
Multiply car count by average repair order and working days to see monthly and yearly revenue, then test what one more car a day, a bigger ticket or opening Saturdays would add.
What if
ARO is total sales divided by the number of repair orders, so use the same definition (with or without tax and fees) for both numbers.

Shop revenue is car count times average repair order (ARO) times the days you're open. 12 cars a day at a $450 ARO over 22 working days is $118,800 a month, about $1.43 million a year. One more car a day adds $9,900 a month; $25 more on each ticket adds $6,600. Multiply by gross profit percent for gross profit.
