According to the BizBuySell Insight Report, which tracks more than 50,000 business transactions annually, the average small business sold for 2.57 times its Seller's Discretionary Earnings in 2024. Most sellers don't know what that number is before they sit across from a buyer. That gap costs them, sometimes six figures, at the closing table.
Seller's Discretionary Earnings is the single most important number in a small business exit. It determines what a buyer will pay. It determines whether your QoE passes clean. It determines whether you close at the headline price or retrade 20 percent lower at the finish line. Every veteran operator who built a business deserves to understand it before they go to market.
What SDE Actually Measures
Seller's Discretionary Earnings represents the total cash flow available to a single owner-operator. It starts with pre-tax net income and adds back everything the owner extracted from the business: salary, benefits, personal expenses run through the company, and any costs that won't continue under new ownership.
The formula:
SDE = Pre-Tax Net Income + Owner's Salary and Benefits + Interest + Depreciation and Amortization + Non-Recurring Expenses + Discretionary Owner Expenses
That number is what a buyer purchases. Not revenue. Not gross profit. Not assets. The total economic benefit flowing to the person who runs the operation every day.
SDE is the standard valuation metric for businesses with under roughly $5 million in annual revenue where the owner is the primary operator. It is the language business brokers, SBA lenders, and individual buyers use when pricing a transaction. If you don't know your SDE, you don't know what your business is worth.
SDE Versus EBITDA: The Cliff Most Sellers Don't See
EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) does not add back the owner's salary or personal benefits. SDE does. That distinction is not accounting noise. It changes the starting number for valuation, and it changes your outcome.
Here is what that looks like in practice. A veteran operator runs a $2.4 million revenue industrial services company. The books show $95,000 in net income. He pays himself a $160,000 salary, runs $40,000 in owner-specific expenses through the company, and has $35,000 in depreciation on equipment. His EBITDA is roughly $130,000. His SDE is $330,000.
At a 2.5x multiple, based on BizBuySell data across more than 9,500 closed transactions in 2025, the EBITDA valuation puts him at $325,000. The SDE valuation puts him at $825,000. The same business. The same books. A $500,000 difference, because the metric changed.
Once a business has a professional management layer and the owner is no longer the primary operator, buyers shift to EBITDA multiples, typically 4x to 8x for lower-middle-market deals above $2 million in EBITDA. EBITDA multiples appear larger on paper because EBITDA is a smaller starting number than SDE. The resulting dollar valuations are often comparable. What changes is which metric applies to your situation, and applying the wrong one produces a wrong answer.
Add-Backs: What Survives Due Diligence and What Doesn't
Add-backs are the adjustments that close the gap between reported net income and SDE. Every add-back must survive a buyer's Quality of Earnings review. That is a financial reconstruction from source documents. The ones that don't survive get pulled at close.
Add-backs buyers accept without pushback: owner's W-2 salary and payroll taxes, owner health and dental insurance, owner retirement plan contributions (SEP-IRA, solo 401(k)), personal life insurance premiums, depreciation and amortization on owned assets, interest expense on business debt, and documented one-time costs such as legal fees, equipment damage, or a non-recurring lease termination.
Add-backs that require documentation: personal vehicle expenses run through the business (buyers want mileage logs tied to business purpose), meals and entertainment (receipts required, business purpose documented), family member compensation at above-market rates (document the rate differential with a market comp comparison), and any travel with mixed personal and business use. These are legitimate, but they will be tested.
Add-backs that create problems: anything that can't be traced to a bank statement or receipt, costs that will continue under a new owner, or compensation adjustments that assume the new owner will run operations at a lower cost than the business currently requires. A buyer won't give credit for an expense that stays on their books after closing.
The IBBA Market Pulse Survey, which aggregates data from certified business intermediaries across the country, consistently identifies documentation quality on add-backs as a primary variable in whether a transaction closes at the stated price or retrades downward at close.
The Retrade: What Poorly Documented SDE Actually Costs
Buyers conduct Quality of Earnings analysis before closing. QoE is not an audit. It is a reconstruction. An accounting firm hired by the buyer goes back to source documents and rebuilds your SDE from the ground up. Every add-back gets tested. Every number gets tied to a receipt or bank record.
If your stated SDE includes add-backs that do not survive this process, the buyer reprices. That repricing happens after you've disclosed to employees, signed an LOI, engaged attorneys, and often made commitments that assume a certain closing number. A retrade at that stage is not just a financial hit. It is a negotiating position with almost no room to walk away. You have already disclosed the business to the buyer and the process has momentum.
According to transaction data from lower-middle-market M&A advisors, poorly documented SDE leads to purchase price reductions of 10 to 30 percent at close. On a $1 million deal, that is $100,000 to $300,000 coming off the table at the moment you are least equipped to walk away.
The operators who avoid retrades documented their add-backs before they hired a broker, not after a buyer's accountant started asking questions. That is the difference between a clean close and a painful renegotiation.
Industry Multiples: Where You Fall in the Range
The 2x to 4x SDE range is the national average across all industries. Your actual multiple depends on factors buyers measure systematically: revenue growth rate, customer concentration, owner dependency, recurring versus project-based revenue, transferability of key relationships, and the quality of your financial records.
Industries with recurring revenue and low customer concentration command higher multiples. Healthcare services, certain B2B service businesses, and software-enabled operations multiples toward the top of the range or above it. Highly owner-dependent businesses with concentrated customer bases trade toward the bottom.
A veteran-owned business that built a reputation around the owner's personal relationships and military network can command a premium on trust and brand, but it can also take a discount if that trust doesn't transfer cleanly to new ownership. Buyers pay for systems, not personalities. The business that runs without you gets priced higher than the business where you are the product.
Know your industry benchmark before you sit across from a broker or buyer. BizBuySell publishes quarterly reports with SDE multiples broken out by sector. IBBA maintains similar data from intermediaries. Knowing the range for your category gives you a factual basis to negotiate the multiple, not just accept the first number a buyer proposes.
How to Prepare Your SDE Before You Go to Market
Pull your last three years of tax returns, bank statements, and profit-and-loss statements. For every expense you plan to add back, write a one-paragraph explanation: what it was, why it was owner-specific, why it won't recur under new ownership, and which source document verifies it. Attach the receipts.
Work with your accountant to rebuild your trailing three-year SDE. Buyers weight recent performance most heavily. If your SDE has grown, make that trend visible and explainable. If it dipped in one year due to a one-time event, document the event and normalize for it.
Reduce owner dependency 12 to 24 months before you sell. Businesses where key client relationships run through the owner's personal cell phone take a buyer's discount for key-person risk. Document processes. Cross-train staff. Move relationships to account managers. This is not just good business practice. It is the difference between a 2.2x and a 3.5x multiple at exit. See also our breakdown of what preparation actually looks like before listing a business.
Get a quality-of-earnings opinion before you go to market. A pre-diligence QoE review from an independent accountant runs $5,000 to $15,000 depending on complexity. It catches the add-backs that won't survive buyer scrutiny before you've signed an LOI. That cost is trivial against a $100,000 retrade. Our analysis of how private equity buyers use QoE breaks down what they're looking for and why.
The Number That Closes the Deal
Special Forces operators run mission rehearsals before executing. You walk the terrain, run through contingencies, identify the failure points before they become casualties. Preparing your SDE for a sale is the same discipline applied to a financial transaction.
Know the number. Document the add-backs. Understand the industry multiple. Fix the owner dependency before a buyer prices it against you. Close at the headline.
The veterans who built businesses over 15 years deserve to exit on their terms. That starts with understanding the one number a buyer will use to determine what those 15 years are worth.

Frequently Asked Questions
What is seller's discretionary earnings and why does it matter for valuing a small business?
Seller's Discretionary Earnings represents the total cash flow available to a single owner-operator, starting with pre-tax net income and adding back the owner's salary, benefits, personal expenses run through the company, and any costs that will not continue under new ownership. It is the standard valuation metric for businesses with under roughly $5 million in annual revenue where the owner is the primary operator. If you don't know your SDE, you don't know what your business is worth.
How does SDE differ from EBITDA, and why does the choice of metric change the valuation outcome?
EBITDA does not add back the owner's salary or personal benefits, while SDE does. That distinction changes the starting number for valuation. A business showing $95,000 in net income with a $160,000 owner salary and $40,000 in owner-specific expenses has a very different EBITDA than SDE, and the resulting valuations at a given multiple can differ by hundreds of thousands of dollars.
Which add-backs are most likely to get challenged during a buyer's quality of earnings review?
Personal vehicle expenses require mileage logs tied to business purpose. Meals and entertainment need receipts with documented business purposes. Family member compensation above market rates requires a market comparison to justify. Anything that cannot be traced to a bank statement or receipt, or any cost that will continue under new ownership, will not survive QoE scrutiny.
What does a retrade cost a seller who has poorly documented SDE add-backs?
Transaction data from lower-middle-market advisors shows poorly documented SDE leads to purchase price reductions of 10 to 30% at close. On a $1 million deal, that is $100,000 to $300,000 coming off the table at the moment a seller is least equipped to walk away. The process has momentum by then, with employees informed, attorneys engaged, and commitments made.
