Understanding Dental Practice Cash Flow Analysis: Why It’s the Key to Valuing Your Dental Practice

Mid-America’s most trusted dental practice valuation and sales

When it comes to determining the fair market value of a dental practice, no single factor carries more weight than a dental practice cash flow analysis

At first glance, this can seem counterintuitive. Most tax returns and financial statements look modest, since practice owners naturally aim to minimize taxable profit each year through legitimate deductions. But when it’s time to value or sell a practice, a Cash Flow Analysis tells a very different story — one that more accurately reflects what the practice can actually generate for a new owner.

What a Cash Flow Analysis Does

Purchasing an existing practice is often the fastest way to step into ownership. Instead of building from the A Cash Flow Analysis takes a close look at the practice’s general ledger to identify expenses that either won’t continue under new ownership or aren’t essential to running the business. These are known as adjustments, or “add-backs,” and they get added back to reported income to arrive at a normalized cash flow figure.

Common examples include:

  • Other discretionary or non-recurring costs
  • One-time equipment replacements (HVAC systems, X-ray equipment, etc.)
  • Personal travel expenses
  • Salaries paid to non-working family members
  • Personal auto expenses

Defensible, Not Just High

It’s tempting to think the goal is simply to maximize cash flow — but that’s not quite right. The real objective is to present the highest defensible cash flow: a number that’s accurate, well-documented, and able to hold up under scrutiny.

Buyers and lenders will conduct their own due diligence, and they’ll expect every add-back to be supported by real records. Estimating or inflating these figures isn’t just risky — it can backfire badly.

A skilled analyst will also flag expenses that look unusually high relative to industry norms. Sometimes this points to a misclassified expense; other times it simply reflects a practice’s particular clinical approach, like a higher reliance on outside labs. Either way, understanding the “why” behind an outlier is part of building an honest picture.

Why Accuracy Builds — or Breaks — Trust

Once a practice goes to market, the accuracy of its financials becomes inseparable from the seller’s credibility.

Consider this scenario: a seller tells the broker that a family member is paid $50,000 a year, and the broker adjusts the cash flow accordingly. During due diligence, the buyer requests W-2s and discovers the actual pay was only $25,000. Now the analysis has overstated cash flow by $25,000 — and worse, the buyer starts questioning everything else in the presented financials. That kind of doubt can stall negotiations or trigger a price reduction.

The same risk runs in the opposite direction. If a seller fails to disclose $10,000 in legitimate personal expenses run through the practice, that omission can understate the practice’s true value — sometimes by roughly double the missed amount, since cash flow is typically capitalized to arrive at valuation.

The Bottom Line

A dental practice’s tax return only tells part of the story. A properly prepared Dental practice cash flow analysis fills in the rest — surfacing legitimate add-backs, questioning outliers, and building a cash flow figure that both buyer and seller can stand behind.

The objective is always the same: present the highest level of cash flow that can be fully and honestly supported by the numbers. When the analysis is accurate and well-documented, sellers can move through the sale process with confidence, and buyers can proceed knowing exactly what they’re getting.

I have worked with Otten-Rey Sales as a “buyer” for two separate practice purchases in recent years. From the buyer’s perspective- I have found Kim very easy to communicate with and very accommodating to any requests I may have had while doing my due diligence. Kim has been a great resource and when the time comes to consider selling, I would absolutely feel comfortable asking her to represent me as a seller as well.

My transition experience was truly smooth and easy from start to finish. Kim made what could have been a stressful process feel very manageable. She was always quick to respond, proactive in communication, and genuinely cared about making sure everything went right. I felt supported and informed every step of the way, which gave me a lot of peace of mind during such a big change. It was a wonderful experience overall, and I’m very happy with how everything turned out. I would absolutely recommend Kim to any dentist going through a practice sale or transition — she really goes above and beyond.

Dr. Hetal Patel Clayton, MO Practice

We consider ourselves lucky to have known and worked with Kim Rey for so many years. She was involved in our purchase 19 years ago and has been a supportive, positive presence in our office management since that time, up until the successful sale of our practice. We feel like our timeline was truly understood when meeting with Kim about our needs and our goals for our practice and our family. She helped to guide us each step of the way with those goals in mind. We feel like the communication was clear and consistent with her management and care of our sale. We always felt like a priority to her and it truly made the sale of our practice an exciting and enjoyable process. I would highly recommend Kim Rey to anyone looking to buy or sell a dental practice.

Dr. Patrick Murphy Arnold, MO Practice

When I decided to buy a dental practice, I quickly learned that practice brokers represent the seller. As a buyer, that posed some challenges. Of all the brokers I worked with in St. Louis, Kim was the only one who managed to make me feel that she was actively trying to find a practice for me to buy. Not only did she help me find a practice I loved, but she still represented her seller well and was fair throughout the entire process. Because of her, I am now the owner of a great dental practice that I love and I truly believe she made that happen for me. Thanks Kim.

Kim’s understanding of all aspects of a transition was invaluable. She has comprehensive knowledge of both the financial and clinical aspects of a dental office. She also provided the guidance and understanding of the legal aspects necessary to close the transaction. Thanks Kim!
