Is owning an auto repair shop profitable? The numbers, line by line
An independent auto repair shop can be very profitable, and it can lose money with the same bays and the same prices. The difference is almost always billed hours: how many hours of labor each tech actually sells in a day. In the worked example below, a two-tech shop loses money at 3 billed hours per tech per day and earns about $170,000 a year before the owner's pay and taxes at 5.
Below is a month of a small shop's numbers, line by line, how to find your own break-even point, and the five things that decide whether your shop makes money.
The example uses round numbers we chose to show the maths. They are not industry averages. Put your own rent, wages and prices in the same lines.
Where a repair shop's money comes from
- Labor. Hours billed times your labor rate. This is the shop's main profit: the cost is the tech's pay for the time, and the rest is margin.
- Parts. Sold at a markup over what you pay. Profit per part is smaller in percent, but it adds up because nearly every job uses parts.
- Diagnosis fees. Paid time to find the fault. Shops that give diagnosis away often give away an hour of their best tech's day.
- Shop supplies and fees (where allowed and disclosed): small, but they cover real costs. See shop fees in auto repair.
- Fleet and business accounts: steady work that fills slow days.
A worked month: a 3-bay shop with 2 techs
Assumptions: 2 full-time techs paid $28 an hour (about 173 paid hours a month each), 20% on top for payroll taxes and benefits, a $130 labor rate, 22 working days, parts sold at a markup that leaves 40% gross margin on parts, and the owner working as service writer without a wage in these numbers. Card fees are figured at 2.5% of sales.
| Line | 3 billed hrs/tech/day | 4 hrs | 5 hrs | 6 hrs |
|---|---|---|---|---|
| Billed hours (month) | 132 | 176 | 220 | 264 |
| Labor sales | $17,160 | $22,880 | $28,600 | $34,320 |
| Parts sales | $13,200 | $17,600 | $22,000 | $26,400 |
| Total sales | $30,360 | $40,480 | $50,600 | $60,720 |
| Tech pay with taxes and benefits | $11,626 | $11,626 | $11,626 | $11,626 |
| Parts cost | $7,920 | $10,560 | $13,200 | $15,840 |
| Rent | $4,500 | $4,500 | $4,500 | $4,500 |
| Equipment payments | $1,200 | $1,200 | $1,200 | $1,200 |
| Insurance | $1,200 | $1,200 | $1,200 | $1,200 |
| Utilities | $900 | $900 | $900 | $900 |
| Supplies, disposal, other | $1,600 | $1,600 | $1,600 | $1,600 |
| Marketing | $600 | $600 | $600 | $600 |
| Shop software | $300 | $300 | $300 | $300 |
| Card fees | $759 | $1,012 | $1,265 | $1,518 |
| Left before owner pay and tax | −$245 | $6,982 | $14,209 | $21,436 |
| Per year | −$2,935 | $83,789 | $170,513 | $257,237 |
Look at what didn't change: the techs are paid the same 8 hours whether they bill 3 or 6. Rent, insurance and the lift payments don't move either. Every extra billed hour drops almost straight to profit, which is why the same shop goes from a small loss to a good living.
Also note what the example leaves out: the owner's own wage, income tax, loan payments on the business purchase, and a reserve for slow months and equipment that breaks. Many owners also work the counter or a bay themselves; if you'd have to hire a service writer, take their pay out of the profit line.
Find your break-even point
Break-even is the number of billed hours a month that covers every cost. Three steps:
- Add up your fixed costs for a month: tech pay (they're paid whether or not they bill), rent, insurance, equipment payments, utilities, software, marketing, supplies.
- Work out what one billed hour brings in after its variable costs: your labor rate, plus the parts profit that comes with an average hour of work, minus card fees.
- Divide the first by the second.
In the example: fixed costs are about $21,926 a month. One billed hour brings $130 of labor plus about $40 of parts profit, minus about $6 of card fees, so about $164. $21,926 ÷ $164 ≈ 133 billed hours a month, or about 3 hours per tech per day. Below that the shop loses money; above it, each hour earns about $164.
Do this with your own numbers once and keep it on the wall. It turns "are we busy?" into "are we above 133 hours this month?"
The five things that decide whether a shop makes money
1. Billed hours per tech
Techs are paid for clock hours; the shop is paid for billed hours. The gap is waiting for parts, waiting for approval, comebacks, unbilled diagnosis and empty bays. Track billed hours against clock hours for each tech every week. Raising the average from 4 to 5 billed hours a day in the example is worth about $7,000 a month.
2. Your labor rate
Many independent shops charge less than nearby shops out of habit. A rate set from your own costs, checked against the going rate in your area, is the second-biggest lever. See how to charge for auto repair for the method and labor rates by state to compare.
3. Parts margin
A parts price matrix (a higher markup on cheap parts, lower on expensive ones) keeps parts profitable without shocking customers on big jobs. Losing money on parts you bought at retail price, or on customer-supplied parts with no labor adjustment, eats the margin.
4. Car count and the average repair order
Billed hours come from cars and from what you sell on each car. More cars come from answered phones, a good Google listing and reminders (how to get more customers). A higher average repair order comes from inspecting every car and explaining what you find with photos, not from pushing.
5. Fixed costs you signed up for
Rent and equipment payments are set the day you sign. A shop with a rent it can only cover at 6 billed hours per tech is fragile. Before signing a lease or buying a shop, run the table above with the new rent.
How much do auto repair shop owners make?
There is no reliable national figure for owner income, and surveys published by software companies and franchises vary widely. What you can work out is your own: the "left before owner pay and tax" line, minus loan payments and income tax. In the example that ranges from nothing to about a quarter of a million dollars a year for the same building, which is why any single average says little about your shop.
For comparison, the US Bureau of Labor Statistics puts the median pay of an employed automotive service technician at $50,620 a year (May 2025) [1]. An owner who works a bay and runs the business should aim to clear well above that, since they also carry the risk, the debt and the hours.
Is buying a shop more profitable than starting one?
Buying gives you customers, equipment and sometimes techs from day one, so you may be above break-even immediately. You pay for that in the price, often with a loan whose payments come out of profit. Starting costs less but you may run below break-even for months while you build car count. Either way:
- Ask for at least three years of the seller's tax returns and monthly sales, not just a summary.
- Check how much of the business depends on the seller personally (their name, their relationships, their bay).
- Look at the lease: years left, rent increases, and whether it transfers.
- Check the state registration and any environmental history of the site.
Startup steps and costs are in how to start an auto repair shop. An accountant who works with small businesses is worth paying to review a purchase.
Warning signs a shop is losing money
- Busy every day, but no cash at the end of the month: usually low billed hours, underpriced labor or parts sold near cost.
- Techs often waiting for cars or parts.
- Diagnosis given away free on most jobs.
- Many comebacks, which cost labor you can't bill.
- Card fees and shop supplies never priced in.
- No monthly profit and loss statement, so nobody knows until tax time.
Day-to-day habits that fix these are in how to run a successful auto repair shop.
FAQ
Is owning an auto repair shop a good business?
It can be, because people always need cars fixed and labor carries a high margin. It's hard work with real fixed costs, so profit depends on keeping techs billing enough hours at a price that covers your costs.
What is a good profit margin for an auto repair shop?
Published figures vary by survey and by what's counted (before or after owner pay). Work out your own from a monthly profit and loss statement, and judge it after paying yourself a fair wage.
How many cars a day does a shop need to be profitable?
Work it out from billed hours: divide your break-even hours by your average billed hours per car. In the example, 133 hours a month at 2 hours a car is about 67 cars a month, or about 3 a day.
Why do auto repair shops fail?
Common reasons are pricing labor too low, too few billed hours, a lease or loan too big for the car count, and no clear numbers to show the problem early.
Does a better website make a shop more profitable?
Only if it brings more booked cars. A homepage that shows what you fix and a call button on a phone turns more searches into calls; the profit comes from the billed hours those calls fill.
If your website is costing you calls, email us your shop's name and we'll build a free preview of a new homepage from what your shop already publishes. More guides are on the auto repair guides page.
