What is owner's cash flow?

In small-business listings, 'owner's cash flow' often means seller's discretionary earnings (SDE): normalized annual earnings available to one full-time working owner before acquisition debt service, income taxes and future capital spending. Ask for the seller's exact definition; listing terminology is not standardized. SDE is not the amount you can immediately withdraw from the bank.

Calculate SDE from reported profit

SDE = reported net income + one owner's compensation and benefits + interest + income taxes + depreciation and amortization + supported non-recurring or owner-specific expenses − any income that will not continue. Check whether each item is already included in net income before adding it. If starting from EBITDA rather than net income, do not add interest, taxes, depreciation and amortization again.

Example (illustrative USD): net income $90,000 + owner wages $80,000 + owner benefits $10,000 + interest $8,000 + income taxes $12,000 + depreciation $15,000 + a documented one-time relocation expense $5,000 = $220,000 SDE. If that relocation expense will happen again, remove the $5,000 add-back and SDE is $215,000. These are example figures, not a valuation of a real company.

Test every add-back

Request the profit-and-loss statements, tax returns, payroll records, invoices and an add-back schedule for the same period. Owner compensation may include salary and benefits for one working owner; paying other working family members is usually a continuing cost unless their duties truly disappear or are replaced at a supported market wage.

Do not add back recurring rent, necessary marketing, routine repairs or an employee who must be replaced. A seller's estimate is a claim until documents show the expense is real and would not continue for a buyer. Reconcile earnings across multiple years, not just the strongest twelve months.

Convert SDE into a buyer's actual cash picture

For a hands-on buyer, SDE includes compensation for their labor. For an absentee buyer, deduct the cost of a capable replacement manager. In either case, plan for debt payments, taxes, working capital and equipment replacement. The result is a more useful affordability check than the listing's 'cash flow' headline.

Frequently asked questions

Is SDE the same as net income?
No. SDE adjusts reported profit for one owner's compensation and supported, non-continuing expenses. Net income generally does not.
Can I add back two owners' salaries?
Generally only one full-time owner's compensation belongs in an owner-operator SDE calculation. Keep the cost of replacing the second owner's work in the expense base.
