The 60/40 rule, and why the seller's collections decide the deal
Practice transition lenders lean roughly 60% on the seller's collections and 40% on the buyer's file. That weighting decides which deals clear.
Direct answer
The 60/40 rule is transition-market shorthand for how an acquisition credit decision is weighted: roughly 60% on the selling practice's historical cash flow and 40% on the buyer's personal file. A strong practice can carry a thinner buyer; a weak one is not rescued by excellent credit. Practition Finance publishes the weighting with its source.
As of October 2026
Why buyers overestimate their own file's importance
A buyer preparing to purchase a practice for the first time naturally focuses on the part of the file they control: personal credit score, savings, tax returns, and a resume showing clinical training. That is the part a buyer can improve before applying, so it gets the most attention, and many buyers assume it is also the part that decides the outcome, since it feels like the variable in their control.
The transition market's own shorthand, the 60/40 rule, says otherwise. It is not a formula any single lender publishes as binding policy, but it captures a consistent pattern across practice lenders: the practice's own historical collections carry roughly 60% of the weight in the credit decision, and the buyer's personal financial strength carries roughly 40%. A buyer with an excellent personal file attached to a practice with declining or erratic collections still gets resized or declined.
The logic is straightforward once stated: debt service on an acquisition loan is paid from the practice's cash flow, not from the buyer's paycheck. A lender underwriting the deal is really underwriting whether the revenue the buyer is purchasing will still be there, and at what level, once the seller walks away. The buyer's personal file matters mainly at the margins, where it decides pricing and structure rather than the basic yes or no.
What the weighting means at each stage of a deal
- 01
The practice's collections history is read first
Three years of monthly collections, not annual production, form the base the entire credit decision rests on. A lender looks for stability or growth, checks how far collections trail production, and flags any decline in the most recent 12 months as a question that needs an answer before anything else in the file gets weighed.
- 02
Transferability of the revenue is read second
Hygiene share of collections, active patient count, and reappointment rates tell the lender how much of the revenue is tied to the departing owner's personal relationships versus the practice's systems and recall base. A practice with strong transferability metrics supports the acquisition credit even when the buyer's own file is average.
- 03
Overhead sets what the practice can actually service
Collections minus overhead is what services the debt, so a practice with rising or above-benchmark overhead reduces the credit available regardless of how strong the top-line collections number looks. Two practices with identical collections can support very different loan amounts once overhead is factored in.
- 04
The buyer's file is weighed last, and mainly decides structure
Personal credit, liquidity, and prior clinical production capacity are read after the practice's numbers are established, and they primarily influence pricing, the size of any equity injection required, and whether a seller note is needed to bridge a gap, rather than the core approval decision on a strong practice.
- 05
The two sides can offset each other, within limits
A very strong practice can carry a thinner buyer file, and a very strong buyer file can occasionally offset a slightly softer practice, but the weighting means the offset only runs so far in either direction. A practice with genuinely declining collections is not rescued by even an excellent personal file, since the underlying revenue risk does not change.
The comparison that settles it
| Side of the file | What is read | Effect on the decision |
|---|---|---|
| Practice (roughly 60%) | Monthly collections trend, three years | Sets the base credit available |
| Practice (roughly 60%) | Hygiene share and reappointment rate | Supports transferability of revenue |
| Practice (roughly 60%) | Overhead ratio | Sets what cash flow actually services debt |
| Buyer (roughly 40%) | Personal credit and liquidity | Sets pricing and equity requirement |
| Buyer (roughly 40%) | Clinical production history | Supports the projection the buyer can replace the seller's output |
What a buyer should actually do with this weighting
Before spending time perfecting a personal financial statement, a buyer evaluating a specific practice should ask the seller for three years of monthly collections detail, hygiene share, and reappointment rates, since those numbers decide most of the outcome. A practice that looks attractive on production or on a broker's summary but shows a declining monthly collections trend is a weaker credit than the sticker price suggests, regardless of how strong the buyer's own file is.
Where the practice's numbers are genuinely strong, a buyer with a thinner personal file should not assume the deal is dead; the weighting works in their favor in that direction too. A seller's actual collections history sets what a note supports before a letter of intent is signed, and, by state, Practition Finance refers the acquisition request to funding partners who present terms directly.
Do not agree to a purchase price based on a broker's annual production summary alone; ask for the seller's monthly collections detail before the price is fixed, since that number decides the loan

What owners ask about this
01Is the 60/40 rule an actual lender policy?
No single lender publishes it as a binding formula. It is directional shorthand from the practice transition market describing a consistent pattern across how practice lenders weigh a credit decision. Its usefulness is in setting expectations correctly, not in predicting an exact outcome from a fixed calculation.
02Can a buyer with excellent credit overcome a weak practice?
Rarely on its own. Debt service is paid from the practice's collections, not the buyer's income, so a practice with declining or unstable collections carries risk that a strong personal file cannot offset. An excellent buyer file more often affects pricing and terms on a viable deal than it rescues a deal built on weak underlying revenue.
03What if the buyer has no prior ownership experience?
A first-time buyer's file is weighed within the roughly 40% buyer-side share, and a strong practice with good transferability metrics can support a first-time buyer's approval even without prior ownership history, provided clinical production capacity is documented through a resume and licensure.
04Does the 60/40 weighting apply outside dentistry?
The specific rule is documented in the dental transition market, but the underlying logic, that debt service comes from the practice being purchased rather than the buyer's personal income, applies across most practice acquisition lending, including veterinary and other licensed healthcare practices, even where the exact ratio has not been formally quoted.
05How does Practition Finance use this weighting with a buyer?
Practition Finance is an independent business financing referral service. It reviews the seller's collections detail against this weighting before a buyer commits to a price, flags where the practice side of the file is weak, and, by state, refers the acquisition request to funding partners once the file reflects the actual underwriting priorities.
