A shop can be slammed all month and still broke at the end of it. In about two minutes, see your effective labor rate, your labor efficiency, and roughly how much you're leaving on the table every year - plus the three places it's bleeding.
Most diesel shops are leaving 10 to 20 points of margin on the table with the crew and bays they already have. It hides in a handful of numbers most owners never track: the gap between your posted rate and what you actually realize, the paid hours that never make it onto an invoice, thin parts margin, and the quiet cost of comebacks. This tool turns those into your numbers - and shows you where to look first.
Rough is fine - this is a directional read, not an audit. We assume a standard 40-hour paid week per tech.
Directional planning estimate, not an audit - built from your inputs, a standard 40-hour paid week, and common industry rules-of-thumb (an 85% labor-efficiency target, a ~38% blended parts margin with a matrix). Most of the figure is billable labor you already pay for but don't capture. Your real numbers depend on your costs, mix, and market.
See your effective labor rate, your efficiency against target, and exactly how the leak splits across unbilled labor, parts margin, and comebacks - so you know what to fix first.
