What is SDE? The number that prices a business.
SDE is the number that turns a business's raw profit into what you are actually buying: the earnings one working owner takes home in a year. Here is the formula in plain words, one worked example, the honest test for every addback, and how that number turns into a price and a loan.

The profit that follows the owner home
Seller's discretionary earnings, SDE, is the profit a business truly puts in one working owner's pocket in a year. Start with pre-tax profit. Add back the owner's salary and payroll taxes, because a new owner replaces that pay with their own labor. Add back perks the business paid for that a new owner would not have to keep paying: a personal vehicle, a family member on payroll who will not stay, memberships that served the owner rather than the business. Add back genuine one-time costs too, a roof replacement, a lawsuit settlement, anything that will not repeat. What is left is SDE, the real number a buyer steps into.
Here is that math on a clean, plausible example: $180,000 pre-tax profit + $110,000 in owner salary and payroll taxes + $25,000 in perks and one-time items = $315,000 in SDE. That $315,000 is the number a buyer, a lender, and a broker will all end up discussing, and the number the rest of this page is really about.
Net income hides the owner's real paycheck
Owner-operated businesses do not keep their books for a buyer's benefit. They keep them to minimize tax, and the owner's own pay and personal spending often sit buried inside ordinary expense lines: officer compensation set for tax reasons rather than market rate, a vehicle, a phone plan, a relative drawing a paycheck for light duties. Net income, the bottom line on a tax return or a profit and loss statement, reflects all of that. It answers a different question than the one a buyer is actually asking.
The question a buyer needs answered is simple. If you step into this owner's chair, what does the business really produce for you in a year? Net income understates that number, sometimes badly, because it was never built to answer this question. SDE rebuilds the figure from the ground up, addback by addback, until it reflects what a new working owner actually takes home.
Would the next owner really not pay this?
Every addback deserves the same honest question. Would the next owner really not pay this? A personal vehicle the business currently covers usually passes that test. So does a one-time legal bill, or a roof that will not need replacing again for twenty years. A repair that quietly shows up every single year, dressed up as one-time, does not pass, no matter what the spreadsheet calls it. Neither does a below-market rent from a landlord who happens to be related to the seller and is about to reset to market rate the day the deal closes.
Inflated addbacks are the single most common way a listing overstates SDE, and they rarely arrive as one dramatic lie. They arrive as a dozen small, generous judgment calls, stacked on top of each other, until the number looks better than the business actually performs. This same test, and the same discipline, matters again when you sit down to read a CIM: the addback schedule buried inside that packet deserves exactly this level of scrutiny, line by line, before you let it move your price.
A multiple prices it. Coverage decides the loan.
Once you trust the SDE number, a buyer applies a multiple to it to arrive at an asking price or an offer. That multiple is not fixed, and this page will not hand you one. Multiples move with the size of the business, the industry it competes in, and how transferable its earnings really are once the current owner walks away. The same $315,000 SDE can price very differently on a business that runs itself versus one where every customer relationship lives in the owner's head.
A lender cares about something stricter than any multiple. They want to know whether SDE covers the loan payments the deal creates, with room to spare. That test has a name, DSCR, debt service coverage ratio, and it is a separate question from what a buyer or seller thinks the business is worth. See what DSCR is and what lenders actually require before you anchor to a price built on SDE alone.
