The Auto Repair Shop
A row of lifts, a crew of ASE-certified techs, and a scan tool that costs more than a used car. The independent shop that keeps a town’s vehicles on the road earns its living on diagnostic labor and marked-up parts, not the loss-leader oil change that gets the car in the door. The whole game is effective labor rate multiplied by the billed hours you can actually staff.

Cited sources Typical bands for this kind of business, compiled from the public sources listed under Sources and method; they are a synthesis, not figures copied from any one source. Estimates, not forecasts; a specific business varies with its location, lease, equipment and owner. Last reviewed 2026-07-07. smbnest is a self-assessment tool, not individualized advice.
A good fit if you
- Know the trade yourself, or can hire and keep ASE-certified master techs and lead them without resentment
- Want a hands-on, skilled business you run from the floor, with grease under your fingernails and an eye on the dispatch board
- Can defend a parts matrix against price-shoppers and hold an effective labor rate while keeping every bay scheduled tight
- Are comfortable competing on trust and diagnostic competence, because the driver who trusts you with their brakes does not shop around
A poor fit if you
- Want an absentee business; an empty bay with no tech in it earns nothing, and this trade punishes the owner who is never there
- Cannot recruit or retain skilled techs in a market where one master leaving can take a chunk of the customers with them
- Plan to win on cheap oil changes, the loss-leader with almost no margin and no diagnostic work behind it
- Underestimate tooling: a scan tool a few model years out of date quietly locks you out of the highest-paying jobs

Sources & Method
Figures are compiled from the public sources below; the bands are a synthesis of them, not copies
How these numbers were built: technician wages come from the BLS; sale prices, revenue, owner earnings (SDE) and multiples from BizBuySell’s 2021 to 2025 auto repair and service benchmarks; car count, bay count and margin ranges from the 2026 Ratchet+Wrench Industry Survey; shop-level cost ratios and opening costs from Meineke’s franchise disclosure; fleet age from S&P Global Mobility; survival from BLS Business Employment Dynamics; and SBA loan performance from an analysis of SBA lending records. The opening kit prices each line from dealer and distributor listings and franchise cost disclosures, checked in October 2026. Rent, other overhead and revenue per bay are planning estimates. These are starting assumptions; once you have a real building, quotes and a crew, your numbers should replace ours.
Cost ratios and margin figures anchor to BLS wage data and BizBuySell five-year (2021-2025) sold-business benchmarks for the auto repair and service category. Occupancy, revenue-per-bay, and revenue-per-square-foot figures are estimated from general shop-format norms since no single public source breaks those out.
This is just the surface
The full model is the complete, interactive deep-dive, and every business here is built to the same standard: a live economics simulator you tune to your own numbers, an interactive 3D walkthrough, a location scorecard, an owner-fit assessment, a buy-versus-build comparison, and the full breakdown of how it makes money and what quietly kills margin.
