Seller's discretionary earnings, or SDE, estimates the financial benefit available to one working owner under an explicitly stated set of adjustments. For a med spa, it must distinguish the owner's clinical and management work from investment return. It is a negotiated financial presentation, not cash automatically available after buying the practice.
What does SDE mean in an owner-operated practice?
Seller’s discretionary earnings is an earnings presentation that combines business profit with specified financing, noncash, owner-compensation, and discretionary adjustments to describe the benefit available to one working owner. State the actual convention used because sellers and advisors may classify items differently.
In a small medical spa, the owner may be the principal injector, manager, recruiter, and public face. SDE can be useful to a clinician buyer who intends to perform similar work. It can also mislead an investor who interprets compensation for those jobs as a return received without working.
Read the valuation hub alongside the calculation. A comparison should identify which duties transfer to the buyer and which require paid replacement. Without that role map, two similarly labeled SDE figures may describe very different businesses.
How do you build the earnings bridge?
Begin with a named starting line from the financial statements for a defined period. Reconcile it to the ledger and tax records. List interest, depreciation, amortization, owner compensation, and any proposed discretionary or unusual items separately, confirming that each actually reduced the starting profit.
The IRS small-business tax guide explains cash and accrual accounting distinctions. A tax return is a useful reconciliation document, but its timing and classifications do not necessarily equal a transaction earnings presentation. Have the accountant explain differences rather than forcing figures to match without a bridge.
Use a spreadsheet with amount, account, invoice or payroll reference, rationale, expected future treatment, and review status. Mark disputed items. A buyer should be able to remove one proposed adjustment and immediately see how the resulting SDE changes.
What does a worked SDE calculation look like?
This is an illustrative calculation using invented inputs, not a client result. Assume net income of $126,000 after a single working owner’s $118,000 compensation, $17,000 interest, $24,000 depreciation, and $8,000 of documented personal expenses recorded through the practice. Assuming the chosen presentation accepts all four adjustments, SDE equals $126,000 + $118,000 + $17,000 + $24,000 + $8,000 = $293,000.
| Line | Amount | Evidence |
|---|---|---|
| Recorded net income | $126,000 | Reconciled statements |
| Owner compensation | $118,000 | Payroll and duties |
| Interest | $17,000 | Loan statements |
| Depreciation | $24,000 | Fixed-asset schedule |
| Personal expense | $8,000 | Itemized receipts |
| Presented SDE | $293,000 | Subject to review |
The calculation does not say that equipment needs no replacement, that debt disappears without payment, or that the buyer can earn $293,000 while hiring someone else to perform every owner duty.
Which add-backs deserve the closest challenge?
Challenge costs that recur under another name, support current revenue, or shift to a replacement employee. Calling marketing optional does not establish that a buyer can stop it while preserving new-patient volume. Calling training unusual does not establish that staff development ends after closing.
Owner compensation needs particular care when several owners work in the practice. Adding back all their pay while assuming only one replacement owner can cover the workload inflates the apparent benefit. Document hours and responsibilities, then retain necessary compensation costs.
Family payroll also requires facts. A relative who performs scheduling or bookkeeping may need replacement at a market cost. A personal vehicle expense may contain both business and personal use. Review underlying records instead of treating the whole account as discretionary. The Four-Number Med Spa Valuation Screen helps separate these operating questions from future capital and prepaid obligations.
How do buyers, sellers, and lenders use the number differently?
A seller uses SDE to explain the economic benefit of ownership. A clinician buyer uses it to assess compensation plus investment return under a chosen workload. A lender evaluates repayment using its own rules, permitted adjustments, obligations, and borrower qualifications.
The SBA 7(a) program overview includes ownership changes among eligible uses but does not endorse a broker’s SDE schedule. Give the lender the supporting reconciliation early, including required owner replacement and post-close liquidity. Loan eligibility and repayment capacity remain separate decisions.
A passive buyer may need an adjusted EBITDA case after paying the necessary management and clinical costs. Link the two cases with a visible staffing bridge. Do not apply an EBITDA multiple to SDE because the resulting price looks more attractive. The measure and the comparison evidence must describe the same economic role.
What can make med spa SDE less transferable?
Examine provider dependence, prepaid services, equipment needs, and legal continuity. A cash collection for future treatment can make a period look strong while leaving work for the buyer. An owner with unusually low staffing cost may perform duties that a replacement team cannot absorb.
The Medical Board of California’s med spa guidance illustrates that professional ownership and treatment personnel matter in California. An investor cannot assume that acquiring the economic benefit permits them to control clinical work. Other states require their own legal review.
Use the Med Spa Continuity Risk Map to identify what must remain operational after closing. SDE should be accompanied by a transition narrative specifying who treats patients, who manages the business, and what commitments are required from the departing owner.
How should seasonality affect the presentation?
A working-owner benefit figure should describe a representative period. If holiday packages, promotional events, or an unusually busy month shift collections, show the full monthly pattern and the related delivery obligations. Annualizing a strong month can produce a much larger number without adding evidence that the practice can sustain it.
Review the owner’s hours across the same period. A higher earnings figure may reflect longer treatment days, fewer vacations, or administrative work performed after hours. A buyer comparing acquisition opportunities needs to know the workload associated with the benefit, not just the total dollars.
When recent performance differs from the prior year, explain the reason before choosing a run rate. A new provider, changed pricing, temporary closure, or completed expansion can justify a separate scenario, but each requires evidence about timing and cost. Present the historical result first and label the prospective case. That separation lets a buyer assess whether the seller’s improvement is already established, still developing, or dependent on a future operating decision.
How should a seller prepare SDE for diligence?
Prepare a repeatable monthly calculation, not just a year-end total. A rolling view can reveal changing margins, a provider departure, or a cash-collection spike that an annual number conceals. Keep period definitions consistent as new months arrive.
- Choose a clearly identified starting profit and accounting period.
- Reconcile statements, tax filings, and material cash movements.
- Document each proposed add-back and whether the cost continues.
- Map one working owner’s duties and any required replacement costs.
- Separate equipment funding, prepaid obligations, and acquisition debt service.
- Present accepted and disputed adjustments without silently changing definitions.
For transaction preparation, follow the 90-Day Pre-Sale Sprint. When an offer arrives, compare actual distributions through the Offer-to-Proceeds Bridge. SDE describes an earnings case; it does not calculate the seller’s net proceeds or the buyer’s spendable cash after financing.
Ask the buyer to identify disagreements by line item. That creates a more useful negotiation than arguing over a single number with no shared definition. Preserve the original schedule and record each revision so everyone can trace how the conclusion changed.
What else do owners and buyers ask?
Is SDE the same thing as my take-home pay?
No. It combines business profit and specified adjustments under a working-owner assumption. Your actual cash also depends on taxes, debt payments, equipment purchases, retained working capital, and distributions. A buyer's future take-home amount may differ because their compensation, financing, staffing, and operating choices differ from yours.
Can I add back the salary of every owner?
Not without examining the jobs those owners perform and the convention used for the presentation. A one-owner benefit measure cannot assume several necessary full-time roles disappear. Show each person's compensation and duties, then explain which work the buyer will perform and which work requires an ongoing paid replacement.
Does a tax-deductible expense automatically qualify as an add-back?
No. Tax deductibility addresses one question; transferability of earnings addresses another. A valid business deduction may remain necessary for the buyer. Support any proposed removal with records and a credible explanation of why the cost will not recur without harming the operation or shifting elsewhere.
Should I use an SDE multiple or an EBITDA multiple?
Use a method and comparison set consistent with the earnings definition, business scale, and buyer's role. Do not mix the measures. If necessary, prepare both a working-owner case and a staffed-management case, with an explicit bridge showing the compensation and costs that separate them before discussing any market evidence.
