What is SDE?

Seller’s Discretionary Earnings (SDE) is a measure of a business’s profitability that includes the financial benefit to a single, full-time owner-operator. It’s calculated as net income plus all of the owner’s compensation, benefits, and personal expenses that run through the business, plus interest, depreciation, and non-recurring items.

SDE differs from EBITDA in one important way: it includes the owner’s compensation. EBITDA assumes the company pays its CEO a market salary; SDE assumes that salary is part of the ‘return’ to a single owner-operator who’ll work in the business full-time.

That distinction matters because SDE is the metric used to value smaller, owner-operated businesses where the buyer will replace the seller and run the business themselves. The same business can have very different SDE and EBITDA numbers — and which metric you use to value it depends on the buyer and the size of the deal.

The SDE Formula

The standard SDE calculation looks like this:

• Net Income (pre-tax)
• + Owner’s salary & bonus (single full-time owner)
• + Owner’s benefits (health insurance, retirement contributions, etc.)
• + Owner’s personal expenses run through the business (vehicle, phone, meals, travel)
• + Family on payroll at above-market compensation
• + Depreciation & amortization
• + Interest expense
• + One-time, non-recurring expenses (legal settlements, one-off projects)
• + Rent normalization (if the owner owns the building and charges above-market rent)
• = Seller’s Discretionary Earnings (SDE)

The most contested line items are the personal expenses and rent normalization. Buyers will scrutinize these heavily during diligence; sellers who pad their SDE with aggressive add-backs face price reductions when the Quality of Earnings report comes back.

SDE vs. EBITDA: Which Should You Use?

The rough rule of thumb in the industry:

• Use SDE for owner-operated businesses with under ~$1M in true EBITDA, where a single full-time owner is involved in day-to-day operations. SBA buyers, search funds, and individual operator-buyers value at SDE.
• Use EBITDA for businesses with $1M+ EBITDA that already have a real management team in place. PE firms, larger strategic buyers, and family offices value at EBITDA.

For the same business, SDE will be a higher number than EBITDA — because SDE adds back the owner’s salary, which EBITDA doesn’t. The corresponding multiples will be different: a 6x EBITDA business is roughly a 4–5x SDE business for the same total valuation.

Common SDE Pitfalls

Aggressive add-backs

The most common mistake sellers make is padding SDE with add-backs that won’t survive buyer scrutiny. Personal vehicle expenses are legitimate if they’re really personal; the family vacation invoiced as ‘research and development’ will get flagged in QofE. Buyers expect 5–15% of total SDE to be add-backs; sellers showing 40%+ add-backs face skepticism.

Failing to normalize owner compensation

If the owner pays themselves $50K (well below market) to minimize taxes, the SDE looks artificially high — but a buyer will normalize it to market and reduce the effective SDE. Conversely, an owner paying themselves $400K to absorb profits creates a discretionary add-back opportunity but raises questions about why the business needs that much management compensation.

Confusing ‘total cash to owner’ with SDE

Some sellers calculate SDE as ‘everything I take out of the business,’ including distributions of profit. That double-counts. Profit is already in net income; distributions are how it gets to you. Don’t add them back separately.

Not having clean books

SDE math relies on add-backs being identifiable in the financial statements. If your books mix business and personal expenses in messy categories, buyers (and their QofE accountants) won’t give you the benefit of the doubt — they’ll back out only what they can clearly verify.

Buyer vs. Seller View

Sellers want SDE to be as high as possible, with as many add-backs as defensible. Higher SDE = higher purchase price.

Buyers want to verify every add-back. They’ll commission a Quality of Earnings (QofE) report that scrubs the numbers, often producing a ‘normalized SDE’ that’s 5–15% lower than the seller’s number. They’ll also question whether the owner’s involvement is truly replaceable at the SDE level being claimed.

The deals that close smoothly are the ones where sellers go to market with conservative, well-documented SDE calculations. Aggressive add-backs invite buyer pushback during diligence — and a re-trade on price is much worse for the seller than starting with a defensible number.
