How the math works

The calculator estimates monthly labor revenue from your tech count, billed hours per tech, and posted labor rate, then applies a gross profit assumption on labor to get your monthly labor gross profit. A software subscription is shown as a percentage of that gross profit, which is the honest way to judge it: $399 a month reads very differently in a two-tech shop than in an eight-bay operation.

It also prices out what a small efficiency gain is worth. If better workflow or digital inspections free up even five percent more billed hours, the calculator shows that dollar value next to the subscription cost, which is usually the whole argument for or against upgrading. When you know your budget, take it into Find Your Match or the comparison chart to see which platforms fit inside it.

Common questions

How much should a shop spend on management software?

Most single-location shops we score land between $99 and $500 a month, and a common sanity check is keeping the subscription under two to three percent of monthly labor gross profit. The calculator shows your exact percentage so you are not guessing.

Does the calculator store my numbers?

No. Everything runs in your browser on this page. Nothing is saved, sent, or attached to you.

What efficiency gain is realistic from better software?

Shops that move from paper or dated systems to a modern platform with digital inspections commonly report higher approval rates and faster estimate turnaround. We use conservative single-digit percentages in the calculator; treat double-digit vendor claims as marketing until your own numbers prove them.
