SDE vs. EBITDA: Which Multiple Applies to Your Business — and Why It Matters

When business owners start researching what their company might be worth, they quickly encounter two acronyms: SDE and EBITDA. Both are measures of business earnings. Both are used to calculate multiples. And confusing the two — or applying the wrong one — can lead to a valuation that bears no resemblance to what the market would actually pay.

What is SDE?

Seller's Discretionary Earnings is the earnings metric used for smaller, owner-operated businesses — typically those generating under $2–3 million in annual revenue. SDE starts with net profit and adds back the owner's total compensation (salary, benefits, and perks), depreciation, amortization, interest, taxes, and any non-recurring or discretionary expenses.

The logic is straightforward: in an owner-operated business, the owner's compensation is part of the earnings available to a new owner. SDE captures the total economic benefit available to a single full-time owner-operator.

What is EBITDA?

Earnings Before Interest, Taxes, Depreciation, and Amortization is the metric used for larger businesses — typically those generating over $2–3 million in revenue, or businesses with a management team that operates independently of the owner. EBITDA does not add back the owner's personal compensation, because at this scale, that compensation represents a real cost that would need to be replaced if the owner left.

EBITDA is the metric most private equity firms, institutional buyers, and strategic acquirers use to benchmark businesses across industries.

Why the distinction matters

The two metrics produce different numbers — and the multiples applied to them are different too. SDE multiples for small businesses typically range from 2x to 4x. EBITDA multiples for mid-market businesses can range from 4x to 8x or higher, depending on industry, growth rate, and the strength of the intangible assets.

Applying an EBITDA multiple to an SDE figure — or vice versa — produces a number that misleads everyone at the table. We see this mistake regularly when owners approach us having received an informal valuation based on the wrong metric.

The normalization question

Whichever metric applies to your business, the quality of the normalization process matters enormously. Normalization is the process of adjusting your financials to reflect the true, recurring earnings of the business — removing one-time expenses, personal items run through the business, above-market owner compensation, and any non-operational income.

A well-normalized set of financials can increase a business's apparent value by 20–40% compared to the raw tax return — not by inflating anything, but by presenting the business fairly.

What drives your multiple higher

Whichever metric applies, the multiple itself is driven primarily by the quality of the business's intangible assets — the strength of the management team, the stability of the customer base, the defensibility of the market position, and the degree to which the business operates independently of its owner.

Two businesses with identical SDE figures can command very different multiples based on these factors alone. The gap between a 2.5x multiple and a 4x multiple on the same earnings base is the gap between a fair outcome and an excellent one.
