An EBITDA multiple divides a defined transaction value by a defined earnings measure. The number is meaningful only when the property, assets, period and labor assumptions match the comparison.
Define both sides of the ratio
Identify whether the price includes land, building, equipment, working capital and assumed obligations. Use the same scope for every comparison. A combined property/business asking price should not be compared casually with a business-only completed transaction.
Normalize earnings with documented adjustments, and show replacement management and rent. SDE and EBITDA describe different labor arrangements. A multiple stated without its earnings definition can be misleading even if the arithmetic is correct.
Evaluate the evidence behind a market range
Ask for transaction date, wash format, operating scale, property scope, closing status and earnings basis. A marketing asking price, an advisor’s scenario and a completed sale are different evidence. National platform commentary may not match a single-site Illinois acquisition.
This guide does not establish a statewide multiple band. When comparable evidence is insufficient, use clearly labeled scenarios and ask how the proposed price performs against financing and reinvestment needs.
Review risk without inventing a premium
Assess paid member collections, retention, lease horizon, owner dependence, equipment obligations and concentration. Describe their effect through cash-flow assumptions and deal terms. Do not automatically add a fixed multiple premium for memberships or a town name.
Keep the buyer’s unproven improvement plan separate from the seller’s historical earnings. A future change may be valuable, but the capital, labor and execution risk belong in that scenario.
Connect the multiple with a reproducible file
Use the valuation-method guide for the earnings bridge. Keep source documents, scope and unresolved adjustments with the comparison so another reader can reproduce the result. A precise ratio does not make unsupported inputs more reliable.
