A lender does not read your business plan to be inspired. They read it to find the number that makes the loan safe, and if your plan does not contain that number they stop reading. For an auto repair shop in 2026 the numbers are car count, average repair order, gross profit by category, and debt service coverage — and under the SBA rulebook that took effect on October 1, 2026, the coverage ratio is tested on the seller’s last two years if you are buying, not on your forecast.
This is what goes in the plan, what the benchmarks actually are, and where applications die.

The short version
- The SBA rulebook in force is SOP 50 10 8.1, effective October 1, 2026. If your adviser is quoting the previous SOP, some of what you have been told is out of date.
- Debt service coverage is not one number. Standard 7(a) wants 1.15. Small loans up to $350,000 want 1.10. Buying a shop wants 1.25 — measured on the seller’s last year or two, not on your projection.
- For a change of ownership the business valuation must be ordered by the lender. One prepared for you or for the seller does not count. If the price is above the valuation, you cover the gap in cash.
- Your projections section lives or dies on four drivers: car count, average repair order, gross profit percentage, and technician efficiency.
- Nationally, 19% of employer-firm applications were denied outright in the most recent Federal Reserve survey, and the top reason given was that lender requirements were too strict.
What actually goes in the plan
Every plan template on the internet gives you the same nine headings. The headings are not the problem. The problem is that four of those sections get skimmed and three get audited, and most first-time owners spend their effort on the wrong ones.
Skimmed: executive summary, company description, market analysis, management team. Write them, keep them short, make them specific to your town rather than to the industry.
Audited: the financial projections, the use of funds, and the debt service coverage calculation. This is where the loan is decided.
The use of funds has to reconcile to the penny
List the equipment with quotes attached, the leasehold work with a contractor estimate, the initial parts inventory, and the working capital. Then show it summing to the loan amount plus your injection. An unexplained “miscellaneous” line is the fastest way to get a second round of questions.
What the real numbers look like — and why there is no “average”
Here is where most plans get caught. People quote “the industry average repair order” as a single figure. The 2026 Ratchet+Wrench Industry Survey — 430+ owner and manager responses, fielded in the first quarter of 2026 — does not publish an average. It publishes a distribution, and the distribution is the honest thing to model against.
| Average repair order | Share of shops |
|---|---|
| Under $200 | 9% |
| $200–399 | 22% |
| $400–599 | 24% |
| $600–799 | 20% |
| $800–999 | 15% |
| $1,000+ | 10% |
Note what that means: the most common band is $400–599, and 45% of shops are above $600 — not “more than half”, which is what gets repeated. Model the band your work mix actually puts you in. A plan that assumes a $900 average repair order for a shop doing brakes and services is a plan that fails in month four.
| Driver | Most common band | Spread |
|---|---|---|
| Monthly car count | 100–149 (20%) | Under 50: 17% · 300+: 10% |
| Posted labor rate | $150+ (25%) | Under $80: 7% · $80–99: 21% |
| Parts gross profit | 50–59% (27%) | Under 30%: 10% · 60%+: 10% |
| Labor gross profit | 60–69% (23%) | Under 50%: 13% · 80%+: 7% |
| Overall gross profit | 50–59% (28%) | Under 30%: 10% · 60%+: 13% |
| Net profit | 15–19% (20%) | None: 7% · 20%+: 19% |
| Technician efficiency | 80–99% (24%) | Under 80%: 21% · 140%+: 3% |
| Bays | 3–4 (25%) | 1–2: 13% · 7–8: 20% |

One trap in the labor rate line
The survey asks for effective labor rate as a percentage of posted rate, not in dollars. The most common answers are 80–89% (24%) and 60–69% (21%). Any plan — or any article — that quotes “the industry effective labor rate is 68%” as if it were a dollar figure has misread the instrument. Put your posted rate in the plan, then show the discount you expect to lose to warranty, comebacks and goodwill.
Capacity
The working planning figure is 2.2 vehicles per bay per day, with roughly 0.7 technicians per bay and one service advisor per three bays. That comes from PartsTech’s 2025 state-of-the-industry report (n=752, published February 6, 2025); Ratchet+Wrench reprints the same figure crediting PartsTech, so treat it as one source, not two.
The break-even page
Two lines of arithmetic that belong in every plan:
- Break-even revenue = fixed costs ÷ gross margin percentage.
- Cars needed per month = fixed costs ÷ (average repair order × gross margin percentage).
Using the most common overall gross profit band above, a shop carrying $40,000 a month in fixed costs needs roughly $67,800–80,000 in sales to clear zero. At a $500 average repair order and 55% margin, that is about 145 cars a month — which lands in the 100–149 band where most shops sit, and tells you immediately whether your bay count supports it.
There is no reliable public breakdown of how an American independent shop’s fixed costs split between occupancy, payroll and insurance. Anyone publishing a tidy percentage pie for that is estimating. Build your fixed-cost line from your own quotes — your lease, your insurance binder, your payroll — not from a benchmark.
What is documented is how shops pay technicians, and it changes whether labor behaves as a fixed or variable cost: flat rate 25%, hourly plus commission 23%, hourly 16%, salary 15%, salary plus commission 15%.
Debt service coverage: the number that decides it
Under SOP 50 10 8.1:
| Situation | Required DSCR | Tested on |
|---|---|---|
| Standard 7(a) | 1.15 | Historical and/or projected |
| 7(a) Small Loan (≤$350k) | 1.10 | Historical or projected |
| Initial acquisition of a shop | 1.25 | Seller’s last fiscal year, or average of last two |
| Owner buyout | 1.25 | Same |
| Business expansion | 1.15 | Same basis |
The line that catches people: if you are buying a shop, your projections are not what gets tested. The seller’s trailing numbers are. A beautiful forecast cannot rescue a shop whose last two years do not cover the payment at 1.25.
Two more rules worth knowing before you sign anything. The equity injection for an initial acquisition is 10% and cannot be reduced or waived. And the valuation must be commissioned by the lender — a valuation you or the seller paid for will not be accepted, and if the agreed price sits above it, the difference comes out of your pocket rather than the loan.
Why applications get turned down
From the Federal Reserve’s 2026 Report on Employer Firms, published March 2026 from a survey of 6,525 firms fielded in late 2025: 52% of applicants were fully approved, 29% partially, and 19% denied. Only 42% received the full amount they asked for.
The reasons applicants were given, in order: lender requirements too strict (46%), too much existing debt (37%), low credit score (30%), insufficient collateral (29%), weak sales (29%), and “lenders do not approve financing for businesses like mine” (29%).
For auto repair specifically, the structural failure point is the one above: a lender-ordered valuation that has to support the price, and an acquisition tested on the seller’s history. Those are two arithmetic gates a buyer cannot argue past with a better narrative.
Frequently asked questions
How long should an auto repair shop business plan be?
Long enough that the financial section is complete and short enough that a loan officer reads all of it. In practice that is usually fifteen to twenty-five pages with the projections as an appendix spreadsheet. No loan officer has ever asked for a longer executive summary.
Do I need a business plan if I am buying an existing shop rather than starting one?
Yes, but it is a different document. The projections matter less because the lender tests the seller’s trailing numbers at 1.25 coverage. What matters more is your explanation of what you will keep the same and what you will change, and why the change does not put the existing car count at risk.
What revenue should I project for year one?
Build it from capacity, not from a wish. Bays × 2.2 cars per bay per day × working days × your realistic average repair order, then discount the first six months for ramp-up. A plan that shows a new shop at the industry median in month one is the kind that gets a second round of questions.
Which SBA program fits a repair shop?
Standard 7(a) goes to $5 million and is the usual route for buying a shop or a building plus equipment. 7(a) Small Loans cap at $350,000 with a lower coverage requirement. Microloans max out at $50,000 and cannot be used for real estate or to repay existing debt — useful for tooling, not for an acquisition.
What do I need to track from day one to keep the plan honest?
Car count, average repair order, and your gross margin, every month. Those three are what the plan was built on and what your lender will ask about at review. Reconstructing them from a shoebox at year end does not work, and it is the reason most owners cannot answer when asked how their actuals compare to the forecast.
Bottom line
The narrative sections of a shop business plan are table stakes. The loan turns on four numbers and one ratio: car count, average repair order, parts and labor gross profit, and debt service coverage — the last of which is measured against the seller’s history if you are buying, and against a 1.15 or 1.10 floor if you are starting.
Build the plan from your own quotes and your own capacity math, use the distributions above rather than a borrowed average, and set up the measurement before you open rather than after.
Garage covers the writing end of that: the repair order, the estimate, the invoice and the vehicle history in one place, so the month’s car count and average repair order come off work you already did rather than off a spreadsheet you rebuild in January. Sales, revenue, tax and commission reports export to CSV; Cost & Profit Analytics sits on the Premium plan.
