At a Glance

Seller's Discretionary Earnings (SDE) is the total financial benefit a single owner-operator takes from a business in a year. It combines net profit, the owner's salary, personal expenses run through the business, and one-time costs, producing a single number that shows a buyer what the business would actually pay them to run it. SDE is the standard valuation metric for small businesses, generally those selling under $10 million.

When small business owners start thinking about selling, one of the first questions they ask is, “How much is my business worth?”  The answer isn’t always simple, but understanding Seller’s Discretionary Earnings (SDE) is one of the most important steps in getting it right.

Whether you're years away from listing or ready to hit the market tomorrow, knowing how to calculate and present SDE properly can dramatically improve your business valuation and help close deals faster.

SDE is the story of your business’s financial performance. When told well, it helps potential buyers see the true earning power of your company and feel confident about making an offer.

Here’s what you need to know about Seller’s Discretionary Earnings, why it matters so much in small business sales, and how to get it right from day one.

Seller’s Discretionary Earnings (SDE) is one of the most common methods for valuing small businesses, especially those under $10 million. 

What Is Seller's Discretionary Earnings (SDE)?

Simply put, SDE is the total financial benefit the current owner takes from the business. It tells a potential buyer what they might reasonably expect to earn if they step into the owner’s shoes.

The SDE formula

The basic formula looks like this: Net Profit + Owner’s Salary + Discretionary Expenses + Non-Recurring Expenses = SDE

Let’s break it down:

• Net profit: Your bottom-line earnings after all standard business expenses have been paid.

• Owner’s salary: What the owner pays themselves as compensation.

• Discretionary expenses (add-backs): Personal expenses that the business paid but aren’t essential to operations (think personal travel, a vehicle, or health insurance premiums).

• Non-recurring expenses: One-time costs that won’t apply to the new owner—like legal fees for a specific lawsuit or a one-off marketing campaign.

Discretionary earnings are a cornerstone of business valuation for small businesses because they account for many of the nuances that go into running a smaller operation. Unlike EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization), which is more commonly used for larger businesses or corporations with complex financials, SDE is designed specifically for owner-operated companies.

For example, an owner’s salary and personal expenses can have a big impact on cash flow, but these aren’t always visible in traditional accounting. SDE adds back these owner-related expenses.

This allows a prospective buyer to compare businesses on an “apples-to-apples” basis. Two companies in the same industry might have the same revenue, but owners often pay themselves differently or run the business in unique ways. By normalizing these financials, SDE shows the true earning potential of the business, regardless of the current owner’s personal decisions.

Say your landscaping business shows a net profit of $100,000. You pay yourself $80,000 as salary. The business also covers $10,000 in personal vehicle expenses and had a $5,000 one-time legal fee this year. Your SDE would be $195,000.

This number gives buyers a clearer view of cash flow and helps them understand the business's true earning potential, not just what appears on the tax return.

A second example: when the add-backs are bigger than the profit

An HVAC company does $1.4M in revenue and reports $85,000 in net profit. On paper it looks thin. Here's the full picture:

Start with net profit of $85,000, then add back:

• Owner's salary: $120,000

• Owner's spouse on payroll, no operational role: $45,000

• Owner's truck, fuel, and phone: $18,000

• Family health insurance premiums: $22,000

• One-time settlement of an employment claim: $30,000

Total SDE: $320,000

Same business, and the number a buyer underwrites just went up 3.8x. At a 3x multiple, that's the difference between a $255,000 asking price and a $960,000 one.

The catch: every one of those add-backs has to be documented. An add-back you can't prove isn't an add-back; it's a number a buyer will strike in diligence, usually after you've already agreed on a price.

What counts as an add-back (and what doesn't)

Add these back, and keep the paperwork listed alongside each one:

• Owner's salary and benefits. Documentation: payroll records and W-2.

• Personal vehicle, travel, meals, and phone. Documentation: expense reports, receipts, mileage logs.

• Owner's health insurance premiums. Documentation: insurance statements.

• Payroll taxes on owner compensation. Documentation: tax filings.

• One-time legal fees or settlements. Documentation: invoices and settlement documents.

• One-time capital projects. Documentation: invoices showing the project won't recur.

• Bad debt write-offs, if genuinely one-off. Documentation: the written-off amount plus an explanation of why it was exceptional.

• Family members paid above market rate — but only the excess, not the full salary. Documentation: payroll records plus a market-rate comparison for the role.

Don't add these back:

• Employee wages. The new owner still has to pay the staff.

• Rent, utilities, insurance, and materials. Real operating costs that continue after closing.

• Interest, taxes, depreciation, and amortization. These get handled as separate adjustments, not as SDE add-backs.

• Deferred maintenance you skipped. Postponing a cost doesn't eliminate it. It transfers it to the buyer, and they'll price it in.

The rule of thumb: an expense is an add-back if the business would keep running exactly the same way without it under a new owner. If removing it would change how the business operates, it stays.

SDE vs. EBITDA: which one applies to your business?

At a high-level, while EBITDA strips out interest expense, income taxes, depreciation, and amortization, it ignores the nuances of owners’ compensation and discretionary spending. The short answer: SDE for owner-operated businesses, EBITDA for businesses with a management team in place.

Here's where the two diverge:

• Who uses it. SDE is for owner-operated small businesses. EBITDA is for larger companies and private-equity-backed deals.

• Typical deal size. SDE applies below roughly $5M–$10M. EBITDA takes over above that.

• Owner's salary. SDE adds it back. EBITDA leaves it in as an expense.

• Personal expenses run through the business. SDE adds them back. EBITDA generally doesn't adjust for them.

• What it assumes about the buyer. SDE assumes the buyer replaces the owner and does the job. EBITDA assumes the existing management team stays.

The distinction is about who runs the business after closing. If a buyer is going to step in and do the owner's job, that owner's salary is money the buyer gets to keep, so SDE adds it back. If the business already pays a general manager who's staying, that salary is a real ongoing cost and EBITDA leaves it alone.

This matters most for service businesses, where profitability often depends heavily on the owner's own involvement.

What SDE multiples actually look like

Once you have SDE, valuation is roughly:

SDE × Industry Multiple = Business Value

Most small businesses trade between 2x and 4x SDE. Where you land inside that range depends on:

• Owner dependence. A business that runs without you is worth more than one that is you.

• Revenue concentration. One customer at 40% of revenue drags the multiple down.

• Recurring revenue. Contracts and subscriptions pull it up.

• Growth trend. Three years of growth beats three flat years at the same SDE.

• Documentation quality. Clean books close faster and at higher prices. Messy books get repriced in diligence.

• Industry. Some sectors simply clear at higher multiples than others.

Why buyers, brokers, and lenders all ask for SDE

Buyers aren't reading your P&L to see how you did. They're reading it to answer one question: what will this business pay me once I'm running it?

SDE answers that directly. It also does three other jobs:

It makes businesses comparable. Two landscaping companies at $1M in revenue can report wildly different profits purely because of how each owner pays themselves and what they run through the books. Normalizing to SDE puts them side by side.

It's what SBA lenders underwrite. Lenders use SDE to calculate debt service coverage. If your SDE can't be documented, the deal can't be financed, and most small business acquisitions are financed.

It sets the asking price. The multiple gets applied to SDE, not to profit. Every dollar of legitimate, documented add-back is roughly two to four dollars of enterprise value.

How to strengthen your SDE before you sell

If you’re preparing to sell, maximizing your SDE well before going to market is one of the smartest moves you can make. 

1. Clean up your bookkeeping. Make sure your financials are accurate and up to date. Clear, organized records are the foundation for a reliable SDE calculation.

2. Separate personal and business expenses. Many owners write off personal expenses to reduce taxable income, but when selling, you’ll likely want to rework your records to highlight SDE instead. This helps buyers see the true profitability of your business. (You can still use your tax-optimized books when filing taxes.)

3. Document every add-back. Keep receipts, invoices, and notes for discretionary or non-recurring expenses. One-time business costs—like building an office addition—can often be treated as add-backs, since these optional projects are unlikely to happen again. Including these adjustments ensures your SDE reflects the normalized earnings a new owner could expect.

4. Present a clear SDE story. Experienced buyers want to see a clear, defensible presentation that builds confidence and reduces risk. Key elements buyers and lenders look for include clean books, transparent add-backs, consistency across years, and ensuring every add-back is defensible. 

5. Work with an advisor. Outside expertise can help ensure your SDE calculation is accurate and defensible, giving buyers confidence in your financials.

Think of it as financial modeling for valuation purposes. The better prepared your numbers are, the easier it is to defend your asking price and keep the sale process moving smoothly.

Frequently asked questions

What does SDE stand for? SDE stands for Seller's Discretionary Earnings. It's sometimes written as Owner's Discretionary Earnings (ODE) or Seller's Discretionary Cash Flow (SDCF) — all three describe the same calculation.

Is SDE the same as profit? No. Net profit is what's left after every expense, including the owner's salary. SDE adds the owner's salary and personal expenses back in, so it's almost always higher — often substantially.

What's a good SDE multiple? Most small businesses sell for 2x to 4x SDE. The multiple depends on industry, growth trend, owner dependence, and how well your financials hold up under scrutiny.

Can I calculate SDE myself? You can get a reasonable estimate from your P&L and tax returns using the formula above, or with the SDE worksheet. For a number you'll defend to a buyer or a lender, get an accredited valuation.

When should I use EBITDA instead of SDE? When the business already has a management team that will stay after the sale, typically above $5M in enterprise value. If a buyer will replace you personally, SDE is the right metric.

Does SDE include the owner's health insurance? Yes, if the business pays it as a personal benefit to the owner. Keep the insurance statements.
