Worked example
Last month Acme Auto’s 2 techs 275 produced hours.
The shop is open 5 days per week and was open 21 days last month.
21 ÷ 5 = 4.2 weeks worked.
275 hours ÷ 4.2 weeks = 65.4 hours per week.
65.4 hours ÷ 2 techs = 32.7 hours.
So, our key number is 32.7
When looking at this number for a typical independent shop which is solidly profitable, this number will normally run between 33 and 40 hours.
Why Auto Shop Owners Need Business Calculators
Whether you're tracking your shop's labor rate, monitoring gross profit, or measuring how your monthly sales compare to the same period last year, having access to these calculations removes the guesswork from shop management. Instead of estimating, you get clarity, which leads to better decisions.
What Makes These Calculators Different
Our calculators are specifically designed for auto repair shops and service centers. Each calculator targets a metric that directly affects your bottom line, from new-customer rate and oil-change capture rate to gross profit per sold hour and true labor rate.
These aren't vanity metrics. They're the KPIs that profitable shop owners track consistently to stay ahead of rising costs, efficiency challenges for technicians, and shifting customer demand.
Benchmark Your Shop Against Industry Standards
It's not enough to know your parts' gross profit percentage; you need to know whether it's within the range of a healthy, thriving shop. These calculators provide a benchmark, helping you identify gaps and set realistic, data-backed goals.
