Auto repair labor rate calculator
Work out the door rate your shop actually needs — from your real costs, your bays, and the profit you intend to keep. No email, no signup.
Break-even labor rate: — /hr
Suggested door rate: — /hr
BayDocket's reports track billed hours and labor revenue per tech automatically, so you can check this number against reality every week. See pricing →
Effective labor rate: — /hr
If your ELR sits below your door rate, the gap is discounts, comebacks, and under-billed hours. BayDocket's per-tech reporting shows you exactly where. See pricing →
The math
How the labor rate formula works
The calculator uses the standard cost-recovery method. First it works out how many billable hours your shop actually produces in a month: techs × billable hours per tech per week × 4.33 (the average weeks in a month). Then your break-even rate is simply total monthly costs ÷ monthly billable hours — the rate at which the shop keeps the lights on and nothing more. The suggested door rate builds your target margin in: break-even ÷ (1 − margin%). (That's a true margin — profit as a share of the price — not a markup on cost.)
Two honest caveats. "Billable hours per tech" is not 40 — between diagnosis time, waiting on parts, and shop chores, most techs bill 25–35 hours in a good week; use your real number, not the wish. And "total monthly costs" means everything: rent, payroll including your own, insurance, utilities, software, the loan on the alignment rack. Shops that undercount costs pick a rate that feels competitive and quietly loses money.
Watch it weekly
Door rate is a decision — effective labor rate is a fact
The rate on your wall is what you charge; the effective labor rate is what you actually collect per billed hour. Divide labor revenue by billed hours for any period and compare it to the door rate. A 10–20% gap is normal life — goodwill discounts, warranty time, the ticket you rounded down. A bigger gap means the posted rate is fiction and your real rate is being set at the counter, one exception at a time. We walk the five places that gap comes from, with a worked week of numbers, in the effective labor rate breakdown.
Tracking ELR weekly turns a vague feeling ("we're busy but the bank account isn't moving") into a number you can act on. That's the whole point of measuring: raise the rate, tighten the discounts, or fix the under-billing — but pick one based on data, not mood. The raw material is already on every ticket you write, from the estimate through to the invoice you collect on; the work is adding it up honestly and often.
Count everything
What goes into "total monthly costs"
This is the input shops get wrong, and they get it wrong low. Rent and payroll are easy to remember. The ones that go missing are the ones that quietly decide whether the year works: your own pay — if you're turning wrenches or writing tickets, the shop owes you a market wage before it owes anybody profit — plus payroll taxes and workers' comp on every hour you pay out, garage liability and property insurance, the loan payments on the lift and the scan tool and the alignment rack, software subscriptions billed monthly and the ones billed annually, uniforms and laundry, shop supplies and hazmat disposal, marketing, card processing fees, and the accountant who files it all. Add utilities, and add the parts and hours you eat on comebacks, because those are real money too. If it leaves the checking account in a normal month, it belongs in the number.
Pull it off your profit-and-loss statement rather than out of memory, then revisit it every quarter. Costs move in one direction, and a rate priced against last January's insurance premium is already behind. A quarterly rhythm also keeps rate changes small and unremarkable — a few dollars an hour that nobody has to argue about, instead of the twenty-dollar jump a shop has to make after three years of not looking. When the number does change, make sure it reaches the documents customers actually see, so the new rate is what lands on the estimate they approve and the invoice they pay, not just the sign behind the counter.
Frequently asked questions
What should my shop labor rate be?
There is no universal number — your rate has to cover your real monthly costs, your bay capacity, and the profit you intend to keep. That is exactly what this calculator works out: enter your costs, techs, and billable hours, and it shows your break-even rate and a suggested door rate at your target margin. Most independent shops in the US land somewhere between $90 and $160 an hour, but the right answer is the one derived from your own numbers.
What is an effective labor rate (ELR)?
Effective labor rate is the labor revenue you actually collected divided by the hours you actually billed. If your door rate is $130 but discounts, comebacks, and under-billed jobs pull your ELR down to $104, that gap is money leaking out of every RO. Measuring ELR weekly is the single fastest way to see whether your posted rate survives contact with reality.
How often should I raise my labor rate?
Review it at least once a year, and any time a big cost moves — rent renewal, a tech raise, insurance. Shops that never touch their rate are usually subsidizing their customers: costs drift up a few percent a year, and a rate that stood still for three years is 10–15% underwater without anyone deciding that.
Is this calculator really free?
Yes — no email, no signup, nothing gated. It runs entirely in your browser and we never see your numbers. BayDocket makes shop management software for small independent shops; if the calculator is useful, the product page is one click away, and that is the whole pitch.
