Auto Repair Sales Forecast Template

Once the assumptions are set, work through the Service Mix Forecast and Car Count Projection sheets. In the service mix sheet, enter your current volume and average ticket for each service category — oil changes, repairs, tires, diagnostics — so the model knows where your revenue is coming from today. In the car count sheet, enter your current active customer base and a realistic new customer acquisition number. Then open the Capacity Analysis sheet and verify that your revenue forecast is actually achievable with your current team. If the implied utilization rate exceeds 90%, either the forecast is too aggressive or you need to plan a hire before that revenue can materialize.

Car count is the heartbeat metric of an auto repair forecast, but ARO is what separates profitable shops from busy-but-struggling ones. Industry benchmarks put the national average ARO for independent shops around $350–$450, but shops focusing on higher-value work — transmissions, engines, ADAS calibration — consistently run $600–$800 ARO with fewer cars and higher margins. A forecast that tracks only car count gives you one lever. A forecast that tracks both car count and ARO by service category gives you visibility into whether growth is coming from selling more services per visit, attracting higher-value jobs, or just running more volume — three very different scenarios with different margin implications.
