Seller's Discretionary Earnings (SDE): The Number That Sets Your Business Price

If you are thinking about selling your business, or even just curious about what it might be worth, you need to understand Seller's Discretionary Earnings. SDE is the single most important number in small business valuation. It tells a buyer exactly how much money they can expect to take home if they step in and run your business themselves.

What Is SDE and Why Does It Matter?

SDE represents the total financial benefit a single owner-operator receives from a business. It starts with net income, then adds back the owner's salary, personal benefits, non-cash expenses, and any costs that would not continue under new ownership. The result is a clear picture of the true earning power of the business.

Buyers care about SDE because it answers their core question: "How much will I actually earn if I buy this business?" Banks care about it too, because SDE determines whether a buyer can service the debt used to purchase the business. A higher SDE means a higher sale price.

SDE vs. Net Income: What Is the Difference?

Net income is what shows up on your tax return after all expenses, including your salary. But small business owners often run personal expenses through the business, take a below-market salary, or have one-time costs that distort the bottom line.

SDE corrects for all of that. It reconstructs the true cash the business generates for its owner. A business showing $50,000 in net income might have an SDE of $180,000 once you add back the owner's $90,000 salary, $20,000 in personal vehicle expenses, and $20,000 in one-time legal fees from a resolved lawsuit.

That difference, $50,000 vs. $180,000, completely changes what a buyer will pay.

Common Add-Backs (with Examples)

Add-backs are expenses that get added back to net income when calculating SDE. Here are the most common ones:

Owner's salary and payroll taxes. Whatever you pay yourself, including employer-side payroll taxes. If you pay yourself $85,000/year plus $6,500 in payroll taxes, that is a $91,500 add-back.

Owner benefits. Health insurance, retirement contributions, life insurance, and any other benefits paid by the business for the owner. A typical add-back here runs $15,000 to $30,000.

Personal vehicle expenses. If the business pays for your car payment, insurance, gas, and maintenance, that is an add-back. Common range: $8,000 to $15,000/year.

Personal travel or meals. Business trips that were really vacations, meals with friends coded as business dinners. Be honest with yourself here.

Depreciation and amortization. These are non-cash expenses that reduce your taxable income but do not actually cost you money each month.

Interest on business debt. A new owner may not carry the same debt, so interest payments are added back.

One-time expenses. A lawsuit settlement, a major equipment repair, a rebranding project. If it will not happen again, add it back.

Discretionary spending. Donations, sponsorships, subscriptions the business does not need to operate. Anything a new owner could cut without affecting revenue.

How Buyers Use SDE Multiples

Once a buyer knows your SDE, they apply a multiple to estimate the business value. The multiple depends on your industry, growth rate, customer concentration, and operational risk.

Here are typical SDE multiple ranges by industry:

• Restaurants and food service: 1.5x to 3x. Lower multiples reflect high labor costs and thin margins. Well-run restaurants with strong brands command the higher end.
• Service businesses (landscaping, cleaning, consulting): 2x to 3.5x. Recurring revenue and documented processes push multiples higher.
• SaaS and technology: 3x to 5x. Recurring subscription revenue, high margins, and scalability drive premium valuations.
• Retail (brick and mortar): 1.5x to 2.5x. Lease dependency and inventory risk keep multiples lower.
• Construction and trades: 1.5x to 3x. Businesses with licensed professionals and repeat commercial clients earn higher multiples.

These are starting points. A business with declining revenue, a single key customer, or an owner who works 80 hours a week will sell at the low end. A business with growing revenue, diversified customers, and documented systems will command the high end.

A Real-World Example

Sarah owns a residential cleaning company. Here are her numbers:

• Net income: $60,000
• Owner's salary: $75,000
• Health insurance (owner): $12,000
• Personal vehicle: $9,000
• Depreciation on equipment: $8,000
• One-time website redesign: $6,000

SDE = $60,000 + $75,000 + $12,000 + $9,000 + $8,000 + $6,000 = $170,000

Her business is a service company with recurring clients and documented processes. A buyer applies a 2.5x multiple.

Estimated business value = $170,000 x 2.5 = $425,000

If Sarah's revenue were declining or she had no documented systems, the multiple might drop to 1.5x, bringing the value down to $255,000. The SDE stays the same, but the multiple reflects the risk.

When SDE Is NOT the Right Metric

SDE works best for small, owner-operated businesses, typically those doing under $1 million in SDE. Once a business is large enough to have a professional management team (where the owner is not doing day-to-day work), buyers switch to EBITDA: Earnings Before Interest, Taxes, Depreciation, and Amortization.

The key difference: EBITDA does not add back the owner's salary, because a larger business needs a paid manager regardless. EBITDA multiples also tend to be higher (4x to 8x or more), because larger businesses carry less risk.

If your business has an SDE above $500,000 and a management team in place, you may want to get a professional valuation using EBITDA. For most small businesses, SDE is the standard.

Improving Your SDE Before a Sale

If you are planning to sell in the next one to three years, focus on increasing your SDE:

• Raise prices where the market allows. Even a 5% increase drops straight to the bottom line. Use our profit margin calculator to model the impact.
• Cut discretionary expenses that do not drive revenue.
• Reduce owner dependency by hiring and training key employees.
• Know your break-even point so you can identify exactly where cost cuts create the most value.

The higher your SDE, the more your business is worth. And the cleaner your books, the easier it is for a buyer to verify that number.
