Dental Practice Debt Ratios in 2026: What Lenders Want to See

A general practice collecting $1 million a year at 68% overhead was financeable in 2025. As of this morning, it isn't. The SBA's SOP 50 10 version 8.1 took effect today as the governing underwriting standard for 7(a) and 504 acquisition loans, and per SBA Information Notice 5000-880695 it lifts the minimum debt service coverage ratio from 1.15x to 1.25x on initial acquisitions, owner buyouts and ESOP deals, while barring lenders from using projected cash flow to clear that test.

Here's our call, and informed owners will argue with it: the ADA's healthy overhead band and your lender's financeable overhead band have come apart, and the top third of that band is now a rejection. The ADA puts healthy general practice overhead at 58% to 68%. We'd tell you the real ceiling for an acquisition carrying bank debt in 2026 is 65%, and that everything between 65% and 68% is a deal you'll either renegotiate or lose.

1.25x Is a Price Control Wearing a Credit Standard's Clothes

The mechanics are plain. A global debt service coverage ratio of 1.25 means the lender wants $1.25 of available cash for every $1 of debt payments, and the word "global" is doing the heavy lifting: it counts your student loans, your mortgage and your car note alongside the practice note. The ADA's own guidance notes that combined student-loan and practice-loan debt commonly lands near $1 million at acquisition. That is the number the coverage test is run against, not the practice loan in isolation.

Raising the floor from 1.15 to 1.25 does not change what a practice earns. It changes what a practice is worth to a buyer who needs a loan, which is nearly every buyer. When the cash flow is fixed and the required coverage goes up, the only variables left are price, down payment and term. That is a price control by another name, and the people who absorb it are sellers of high-overhead practices, not banks.

Buyers will feel it as fewer approvals. Sellers will feel it as broken deals at 90 days. We think sellers are the ones who should be worried, and most of them have no idea this happened.

Six Points of Overhead Is $60,000 a Year

Run the scenario. A general practice collects $1,000,000. The price is $750,000, you put 10% down under SBA 7(a), and you finance $700,000 including transition working capital. Assume a 10-year amortization at 10.5%, which puts the practice note at roughly $9,445 a month, or $113,340 a year.

Now add the rest of your life, because the lender does. Say $300,000 of student debt on a 20-year schedule at 7%, which is $2,326 a month or $27,912 a year.

Add a $2,800 home mortgage payment and a $550 car payment, which together run $40,200 a year. Total global debt service: $181,452.

At the old 1.15x floor, you needed $208,670 of cash flow available for debt service. At 1.25x, you need $226,815. The rule change moved the bar by $18,145 a year on this one deal.

Now the practice side. At 68% overhead, operating expenses are $680,000 and cash flow before owner compensation is $320,000. Deduct a $100,000 living and tax allowance for the buyer, which any serious underwriter will, and you have $220,000 against $181,452 of debt service. That is a 1.21 coverage ratio.

It cleared 1.15 last week. It fails 1.25 today, by $6,815 of cash flow.

Take the same practice at 62% overhead. Expenses are $620,000, cash flow is $380,000, and after the same $100,000 allowance you have $280,000. That's a 1.54 coverage ratio and a lender who stops reading the file.

Six points of overhead on a million-dollar practice is $60,000 a year, and as of today it's the difference between a lender's yes and a lender's no.

Your Lender Doesn't Want 1.25. It Wants 1.38

The floor is not the target, and treating it as one is how buyers get surprised at committee. An analysis of 40 dental acquisition term sheets from 2024 to 2026 found a median coverage ratio at origination of 1.38, with SBA 7(a) deals averaging 1.41 against 1.35 for conventional loans. Lenders were already pricing in cushion above the old 1.15 minimum. There is no reason to expect them to suddenly fund at the new one.

So solve for 1.38 instead. On our scenario, that means $250,404 of cash flow available for debt service, which is $30,404 more than 68% overhead produces.

Run the practice at 65% overhead and expenses are $650,000, cash flow is $350,000, and after the living allowance you have $250,000. Coverage lands at 1.38, right on the median.

That is where the 65% ceiling comes from. It isn't a clinical number or a benchmark anyone published. It is the arithmetic of what a bank will actually fund, and it sits three full points below the top of the range every consultant still calls healthy.

What Most Owners Get Wrong: They Underwrite the Practice, Not the Borrower

The mistake belongs to two groups. First, buyers in their early thirties with $300,000 of student debt who shop practices on EBITDA multiples and never once model their own mortgage into the coverage test. Second, and more expensively, sellers in their late fifties who price a practice on last year's collections and assume the buyer's financing is the buyer's problem.

It isn't. The word in the ratio is global. A practice that supports a 1.4 coverage ratio for a debt-free associate supports 1.15 for a buyer carrying student loans and a mortgage, and the bank declines the same practice twice depending on who walks in with the offer. If you're selling, your buyer pool has just been narrowed to people with clean personal balance sheets, and that pool is smaller than your broker's pipeline suggests.

Owners also tend to treat overhead as a management metric and debt coverage as a finance metric, as if they lived in different spreadsheets. They don't. Overhead is the only input to coverage you control, and it takes twelve months of clean books to move it in a way a lender will count.

The Projection Loophole Just Closed, and That's Good News

The quieter half of the SOP 50 10 8.1 change matters more than the number. Lenders can no longer use projected cash flow in place of historical performance to satisfy the coverage test on acquisitions. That kills the oldest trick in dental lending: the pro forma that assumes the new owner adds two hygiene days, drops the PPO with the worst fee schedule and cuts supply spend by 2%, all starting in month one.

We think that's a good rule, and we'd have written it ourselves. Those projections were almost never wrong about the opportunity and almost always wrong about the timeline. A buyer who needed the pro forma to clear 1.15 was a buyer with no margin for a six-month collections dip after the seller walks out.

Our view: if your deal only works on a projection, you don't have a financing problem, you have a price problem. We wouldn't take that deal even if your lender found a way to fund it.

$75,000 at Closing Was a 2019 Number

The ADA recommends closing with $50,000 to $75,000 in cash reserve. We'd treat the bottom of that range as unusable. At 68% overhead on $1,000,000 of collections, monthly operating expense is $56,667, so $50,000 does not cover one month of running the practice you just bought.

We'd want $100,000 at closing, which is about 1.8 months of overhead, and we'd want it on top of the down payment, not carved out of it.

That changes the cash math. On a $750,000 purchase, SBA 7(a) and 504 down payments start at 10%, so $75,000 plus a $100,000 reserve means $175,000 of liquidity. Conventional lenders typically want 15% to 20%, which is $112,500 to $150,000 down, or $212,500 to $250,000 all in.

Conventional money looks cheaper on the rate sheet and costs an extra $37,500 to $75,000 at the table. For a first acquisition, we'd take the SBA paper and keep the cash.

Specialists Have About $640,000 More Room Than They Use

The income base the coverage test measures against is not the same for everyone. ADA Health Policy Institute data puts average 2025 net income at $215,320 for general-practitioner owners and $346,520 for specialist owners. That $131,200 gap supports $104,960 of additional annual debt service at 1.25x coverage.

At the 10-year, 10.5% terms in our scenario, every $700,000 borrowed costs $113,340 a year, so that extra coverage carries roughly $648,000 of additional principal.

Specialists tend to be the most conservative borrowers in dentistry and the ones with the most unused capacity. If you're a specialist owner looking at a second location or a building purchase, the 1.25x floor is not your constraint. It never was.

Three Things to Do Before You Sign the LOI

Pull your trailing twelve months and compute overhead as a percentage of collections with doctor compensation excluded, then compare it to 65%, not 68%. Build your global debt service by hand this week: practice note, student loans, mortgage, auto, everything, and divide practice cash flow after a $100,000 living allowance by that total. If the answer is under 1.38, you're negotiating price or walking, so decide which before the lender decides for you.

We're watching two things from here. If the median origination coverage ratio drifts from 1.38 toward 1.45 over the next two quarters, the effective overhead ceiling drops below 65% and asking prices on high-overhead practices have to come down with it. What would change our mind is lenders stretching amortization or blending in real estate to manufacture coverage, or conventional banks holding at 1.15 and quietly taking the acquisition market from the SBA. Either one resets the math in this piece, and we'll say so when it does.

If you want to know whether your practice sits on the financeable side of that 65% line, start with overhead, since it's the only input to the coverage test you actually control. Use our free overhead calculator to run your own numbers on collections, operating expense and doctor compensation, and see what coverage ratio your practice would produce for a buyer carrying $300,000 of student debt.
