Seller's Discretionary Earnings — SDE — is the single most important number in valuing a small business. It's what buyers actually apply a multiple to, so understanding your SDE tells you far more about what your business is worth than revenue or even net profit. This guide explains what SDE is, how to calculate it, and how it drives your valuation.
Key takeaways
- SDE is the total financial benefit one owner-operator gets from a business in a year.
- Calculate it as net profit plus owner's compensation, one-time/personal expenses, depreciation, and interest.
- SDE is used for owner-run small businesses; EBITDA is used for larger, manager-run ones.
- Small businesses typically sell for roughly 2x–4x SDE, so a clean, higher SDE lifts your valuation.
What is Seller's Discretionary Earnings (SDE)?
SDE is the total financial benefit a single owner-operator gets from a business in a year. It starts with net profit and adds back the owner's salary and benefits, one-time or personal expenses, and non-cash items like depreciation. The goal is to show a buyer the full earning power of the business before an individual owner's personal choices and compensation.
How to calculate SDE
Start with the business's pre-tax net profit, then add back the items a new owner wouldn't necessarily carry or that don't reflect true operating cost:
- The owner's salary, payroll taxes, and benefits (one owner's compensation)
- Discretionary and one-time expenses (a personal vehicle, travel, a one-off legal bill)
- Non-cash expenses — depreciation and amortization
- Interest expense
SDE vs. EBITDA — which applies to you?
SDE is used for owner-operated small businesses, where a single owner runs the show, so it adds that owner's compensation back in. EBITDA (earnings before interest, taxes, depreciation, and amortization) is used for larger businesses that already pay a management team, so it doesn't add back an owner's salary. As a rough line, businesses under about $1–2M in earnings are valued on SDE; larger ones on EBITDA.
- SDE adds back one owner's full compensation; EBITDA does not
- SDE fits owner-operated small businesses; EBITDA fits manager-run ones
- Using the wrong metric can misprice a business significantly
How SDE drives your valuation
Buyers value a small business as a multiple of SDE — commonly 2x to 4x, depending on industry, growth, and how dependent the business is on the owner. So SDE does double duty: a higher, cleaner SDE both raises the base number and supports a higher multiple. Our valuation guide breaks down how those multiples are set.
- Value ≈ SDE × the multiple
- Most small businesses land around 2x–4x SDE
- Recurring revenue and low owner-dependence push the multiple up
Add-backs: getting them right
The add-backs are where SDE is won or lost. Legitimate add-backs — a true one-time cost, or an owner's above-market salary — raise your SDE. But buyers scrutinize every one, so each needs to be defensible and documented. Aggressive or vague add-backs erode buyer trust and can sink a deal, so keep them clean and supportable.
Know your SDE before you sell
Because SDE is the foundation of your valuation, knowing it — and cleaning it up — is the highest-leverage preparation you can do before a sale. Our free valuation calculates your SDE and applies a realistic multiple, so you walk into any conversation already knowing your number.

Frequently asked questions
What is SDE in business?
SDE stands for Seller's Discretionary Earnings — the total financial benefit a single owner-operator receives from a business in a year. It's calculated by taking net profit and adding back the owner's compensation, one-time and personal expenses, depreciation, and interest, and it's the number buyers use to value small businesses.
What's the difference between SDE and EBITDA?
SDE adds one owner's salary and benefits back into earnings and is used for owner-operated small businesses. EBITDA doesn't add back an owner's salary because it assumes a paid management team, and it's used for larger businesses. Using the wrong one can misprice a business by a lot.
What add-backs are allowed in SDE?
Common, defensible add-backs include the owner's salary and benefits, genuine one-time expenses, personal expenses run through the business, depreciation and amortization, and interest. Each must be documented and reasonable — buyers scrutinize add-backs, and aggressive ones undermine trust.
What multiple of SDE do businesses sell for?
Most small businesses sell for roughly 2x to 4x SDE, but the exact multiple depends on the industry, growth trend, recurring revenue, and how dependent the business is on the owner. Durable, transferable earnings command the higher end of the range.
Is SDE the same as cash flow?
They're related but not identical. SDE is a normalized measure of the earnings available to a single owner-operator, built from net profit plus specific add-backs. It's often described as a form of owner cash flow, but it's a defined valuation metric rather than the raw cash movement on your bank statement.
