What a Dental Practice Loan Actually Costs in 2026

A median SBA dental acquisition loan in 2026 is $853,000, and at today's pricing it will take $10,689 out of your practice every month for ten years before you pay yourself a dime. That's the number that matters, and almost nobody shops for it. They shop for the rate.

Here's the claim an informed owner can argue with: the interest rate is the least consequential number on your term sheet. Our view is that you should be willing to pay a full point more in rate to buy a practice with real cash flow cushion, because one soft year of production costs more than the worst rate you'll ever be quoted. The spread is a rounding error next to the price you pay and the collections you inherit.

$853,000 at 8.75% Costs $10,689 a Month

Start with the base. The U.S. bank prime loan rate was 7.00% as of October 13, 2026, and nearly every bank and SBA practice loan is quoted off it as Prime plus a spread. Well-qualified dental buyers are getting SBA 7(a) pricing around Prime + 1.5% to 2.0%, which penciled to 8.25% to 8.75% when prime sat at 6.75%. With prime at 7.00%, that same borrower profile prices at 8.50% to 9.00% today.

Take the midpoint, 8.75%, on the median SBA dental acquisition loan size of $853,000, amortized over the 10-year maximum term for a practice purchase. The monthly payment is $10,689. That's $128,268 a year in debt service. Over the full term you'll send the bank $1,282,680, of which $429,680 is interest.

Now the reality check on rate shopping. Bay Street's book of SBA 7(a) dental loans closed between October 2023 and June 2026 shows a median rate of 9.25%, with the middle 50% of deals between 7.5% and 10.74%. At 9.25% your payment is $10,921, or $2,784 more a year. At the 10.74% top of that middle band, it's $11,621, or $11,184 more a year. Those are real dollars. They are also smaller than a 5% production miss on a $1.4M practice, which costs $70,000 in a single year.

The Ceiling Is 10.00%, and It's Knowable

You are not negotiating in the dark. The SBA caps how far above the base rate a lender can mark up a 7(a), and the cap scales down as the loan gets bigger: under its 7(a) rate structure, loans of $50,000 or less are capped at base plus 6.5%, $50,001 to $250,000 at base plus 6.0%, $250,001 to $350,000 at base plus 4.5%, and anything above $350,000 at base plus 3.0%.

Run that against prime. Any practice acquisition loan above $350,000, which is to say essentially every acquisition loan, has a hard ceiling of 10.00% today. The full negotiating range between a strong file and the legal maximum is 125 basis points: 8.75% to 10.00%. On $853,000 over ten years, that gap is worth $583 a month, $6,996 a year, and $69,960 across the term.

So the entire prize for being the bank's favorite borrower, measured over a decade, is about what you lose from one bad year of collections. If a lender quotes you above 10.00% on a 7(a) over $350,000, the problem isn't the market. Something in your file, your deal, or your lender is off, and you should go find out which before you sign anything.

What Most Buyers Get Wrong: 1.25 Is a Floor, Not a Target

The specific mistake, and it is made overwhelmingly by first-time buyers working with a lender the broker introduced: treating the bank's minimum debt service coverage ratio as the goal. Lenders generally require a minimum DSCR of 1.25. Buyers hear that, build a pro forma that lands at 1.26, and congratulate themselves on a deal that cleared underwriting.

A DSCR of 1.25 means that for every dollar of debt service, the practice generates $1.25 of cash available to pay it. On $128,268 of annual debt service, that's $160,335 of coverage. The cushion is $32,067 a year, or $2,672 a month. One hygienist on maternity leave, one associate departure, one $18,000 chair replacement, and the cushion is gone.

The deals that actually close aren't sitting at the floor. The median DSCR across analyzed dental deals was 1.38. At 1.38, the same loan needs $177,010 of coverage, which is $16,675 more cash flow than the 1.25 minimum. That $16,675 is not a bank requirement. It's the margin between a practice that survives a bad quarter and one that calls the lender in month fourteen. We wouldn't sign a deal that pencils below 1.35, and we'd walk from one that only works at 1.25 if every assumption holds.

Your $400,000 Student Loan Underwrites the Deal Too

The number buyers leave out of the model is the one they already owe. A typical dentist carries roughly $400,000 in student loan debt at the point of practice ownership, rising to about $1 million in total debt once the acquisition loan lands. Lenders underwrite your global cash flow, not just the practice's.

Assume your student loan service runs $3,200 a month, or $38,400 a year. Combined debt service becomes $166,668. Clearing 1.25 on that combined figure requires $208,335 of cash flow, which is $48,000 more than the practice-only test implies.

Translate that into chair time. If your pro forma leaves 20 cents of every collected dollar after paying yourself an associate-level salary and covering everything else, $208,335 of coverage requires about $1.04M in collections just to satisfy the global test. That's the real floor on practice size for a buyer carrying $400,000 in student debt, and it is substantially higher than the floor the acquisition loan alone would suggest. Buyers who skip this step don't get declined. They get approved for a practice that's too small for their personal balance sheet.

A Quarter Point Is Drift. A Bad Spread Is Erosion.

Most 7(a) loans float with prime, so your payment moves. Apply Drift vs. Erosion to the two different things that can happen to your cost of capital.

Drift: prime ticks up 100 basis points over two years. On $853,000 at 8.75% going to 9.75%, the payment moves from $10,689 to $11,154, about $465 a month or $5,580 a year. That is an operational problem with operational answers: three more crown units a month, a fee schedule update, tighter supply ordering. You manage it and move on.

Erosion: you accepted base plus 3.0% at origination because you didn't shop, didn't clean up your file, or didn't know the cap existed. That spread is now contractually welded to a ten-year note. It doesn't respond to better hygiene scheduling. It costs $69,960 over the term and the only fixes are refinancing or selling. Same with a purchase price that locks you at 1.25 DSCR in year one: no amount of operational discipline repairs a deal structured without cushion.

The expensive mistake is confusing the two. Owners panic about rate drift they can absorb and shrug at structural erosion they can't.

The 25-Year Payment Looks Cheap Until You Total It

Practice loans run up to 10 years, extending to 25 years when real estate is part of the deal. The longer term is seductive. Amortize $853,000 at 8.75% over 25 years and the payment drops to $7,013, saving $3,676 a month.

Then total it. Over 300 payments you'd send the bank $2,103,900, of which $1,250,900 is interest. That's $821,220 more interest than the ten-year note.

This is not an argument against buying the building. It's an argument for knowing which dollars you're stretching. Real estate on 25 years is financing a durable asset. Goodwill on 25 years, where it's even available, is financing a practice you may not own that long. Our call: stretch the building, never the goodwill, and use the lower blended payment to buy DSCR cushion rather than a bigger purchase price.

Cash at Close: $85,300, or $42,650

SBA acquisition deals require a 10% equity injection, which can drop to as little as 5% cash when a seller standby note covers the rest. On the median $853,000 loan, that's $85,300 of your money, or $42,650 if the seller stands behind half of it.

Don't spend the savings. The ADA's guidance is to hold $50,000 to $75,000 in cash reserves at closing, on top of the injection. Full cash at close is therefore $135,300 to $160,300 without a standby note, or $92,650 to $117,650 with one. A standby note isn't a discount on the deal. It's a way to show up with reserves intact, which is the single best predictor that you'll still own the practice in year three.

Four Moves Before You Sign the Term Sheet

Pull a current prime quote and compute your ceiling: prime plus 3.0% on anything over $350,000, which is 10.00% this week. Rebuild your pro forma with your student loan payment inside the debt service line and confirm the deal still clears 1.35 globally, not 1.25. Ask the seller directly about a standby note for half the injection, and bank the freed cash as reserves rather than as a larger down payment. Then get a second lender quote from someone the broker didn't introduce you to, because the only way to know your spread is negotiable is to make two people bid for it.

What we're tracking next: whether the well-qualified spread holds at Prime + 1.5% to 2.0% if prime moves again, and whether the median closed DSCR drifts below 1.38, which would be the first real sign that lenders are loosening into a softer acquisition market. A single prime cut wouldn't change our view. Lenders accepting 1.25 deals at scale would.

Before you take a term sheet to a bank, know what the practice is actually worth and what it can actually carry. Our free valuation calculator takes collections, overhead and owner compensation and tells you the supportable purchase price and the debt service that price implies, so you walk in with your own DSCR number instead of the broker's. Run your own numbers and see whether the deal in front of you clears 1.35 or only 1.25.
