Seller's discretionary earnings, without the add-back fiction

Seller's discretionary earnings, usually shortened to SDE, is an attempt to show the total financial benefit available to one working owner before certain discretionary and nonrecurring expenses. It is common in the sale of owner-operated small businesses.

SDE is not the cash a buyer can automatically take home. Debt service, taxes, capital spending, working capital, and the cost of replacing the seller's labor still matter.

Start with a consistent reported profit figure. Then build a documented bridge for owner compensation, interest, taxes, depreciation, amortization, and qualifying discretionary or nonrecurring expenses. Avoid mixing tax-return figures with internal statements unless you reconcile them.

The label matters less than the bridge. A buyer should be able to trace every adjustment back to a source document and explain why the cost will not continue.

Common proposals include personal expenses run through the business, one-time professional fees, above-market owner compensation, and expenses tied to an event that will not recur. Each one needs a document and a reason.

Reject an add-back when the expense is required to operate, likely to recur, unsupported, or replaced by another cost after closing. If the owner performs a full-time job, adding back all owner pay without restoring the cost of that labor overstates the benefit.

EBITDA removes interest, taxes, depreciation, and amortization from earnings. SDE usually goes further by considering one owner's compensation and certain discretionary expenses. That makes SDE more common for owner-operated businesses and EBITDA more common when a management team is already in place.

The practical difference is the labor assumption. SDE normally measures the benefit available to one working owner, so one owner's compensation may be added back. EBITDA measures earnings before financing, tax, and noncash charges, but it does not assume that management labor is free. If the buyer will hire a manager, the analysis must restore a market-rate cost before testing debt service or value.

Start from the same financial statements and build two separate bridges. The SDE bridge identifies one owner's pay and defensible discretionary items. The EBITDA bridge removes interest, taxes, depreciation, and amortization, then normalizes nonrecurring items without adding back ordinary management cost. A company can therefore report higher SDE than EBITDA without creating any extra cash.

Do not compare an SDE multiple with an EBITDA figure, or an EBITDA multiple with SDE. The earnings basis and the multiple must match.

Use the SDE versus EBITDA comparison for a side-by-side bridge and a buyer-focused decision rule.

Rebuild the same earnings measure for several years and the trailing period. Look for revenue quality, margin drift, owner changes, unusual expenses, and the point at which the seller began preparing the business for sale.

Our SDE and add-back calculator makes the comparison visible. A stable result is more useful than a peak result that only exists because one year received special treatment.

After normalizing SDE, apply a relevant transaction range and adjust for the company's transferability and risk. Then test whether the proposed price leaves enough cash flow for debt, owner pay, and reinvestment.
