Lenders do not size acquisition loans on seller's discretionary earnings. SDE adds the owner's entire pay back into profit, which suits a buyer asking what one working owner could take home, but not a lender asking what is left to service debt. Lenders start closer to EBITDA: they subtract a market salary for whoever will run the business, then maintenance capital spending and taxes, and test coverage on what remains. That figure is always smaller than SDE, so a price quoted as a multiple of SDE usually supports less debt than the buyer expects.
- What SDE adds back
- The whole of one owner's pay, plus interest, depreciation and discretionary costs
- What EBITDA assumes
- Everyone, including management, is paid a market wage
- What lenders subtract from SDE
- A market salary, maintenance capex and taxes
- Coverage lenders test
- 1.25x on historical results for an SBA change of ownership from 1 October 2026; conventional banks commonly look for 1.25x
- Leverage multiples
- Applied to EBITDA, never to SDE
The whole difference is one owner's pay
Seller's discretionary earnings (also called owner's cash flow or discretionary cash flow) is pre-tax profit with the owner's entire compensation added back, along with interest, depreciation and amortization, and expenses the owner chose to run through the business. It answers one question: if one person bought this business and ran it themselves, how much would they have before debt, tax and reinvestment?
EBITDA is earnings before interest, taxes, depreciation and amortization, after every person who works in the business, management included, is paid a market wage. It answers a different question: what does the business earn if the owner is simply an owner?
| Item | In SDE | In EBITDA | In the lender's cash flow |
|---|---|---|---|
| Owner's salary, payroll taxes and benefits | Added back in full | Replaced by a market salary for the role | Replaced by a market salary for the role |
| Personal expenses run through the business | Added back | Added back, if documented | Added back, if documented |
| Interest and depreciation | Added back | Added back | Added back; new debt service is tested separately |
| Capital spending to keep the business running | Ignored | Ignored | Subtracted |
| Income taxes, or distributions to pay them | Ignored | Ignored | Subtracted |
| A second working owner's pay | Usually still an expense | At market | At market |
Because SDE counts only one owner, a business with two partners who both work full time has an SDE that already includes one market-level salary as a cost. That is one of several reasons SDE figures from different listings are rarely comparable, and why the side-by-side comparison of SDE and EBITDA is worth reading before comparing two businesses on the same multiple.
Why business listings quote SDE
Most businesses sold through brokers are owner-operated. The typical buyer is a person who will replace the seller at the desk, and for that buyer SDE is an intuitive number: it is roughly what the job and the ownership together pay. It is also the larger number, and a listing that leads with the larger number is not doing anything wrong, only something incomplete.
Multiples quoted on SDE tend to be lower than multiples quoted on EBITDA for the same business, because the base is bigger. That makes an SDE multiple look modest, and it is easy to carry that impression into financing. A buyer who assumes the lender will look at the same base is where the trouble starts. Larger companies with a management team in place are marketed on EBITDA, because nobody expects the buyer to do the chief executive's job personally, and the question of whose pay to add back does not arise.
How a lender turns SDE into lendable cash flow
Lenders walk from the seller's reported earnings to cash available for debt service in a sequence that looks like this. The numbers are illustrative, for a business with SDE of 1,000:
| Step | Amount | What the lender is doing |
|---|---|---|
| Seller's discretionary earnings | 1,000 | The broker's figure, checked against the tax returns |
| Less: market salary for the operator | 220 | Paying whoever runs the business after closing, including payroll taxes and benefits |
| EBITDA | 780 | Earnings as if the owner were only an owner |
| Less: maintenance capital spending | 90 | Replacing trucks, equipment and systems that wear out |
| Less: income taxes or tax distributions | 120 | Cash that leaves the business whoever owns it |
| Cash flow available for debt service | 570 | The figure the coverage test is run on |
Each deduction is a judgement the lender makes from evidence. The market salary depends on the role, the region and the size of the business, and a buyer who plans to pay themselves less does not get credit for it. Maintenance capital spending is read from several years of fixed-asset purchases, not from what the seller says the equipment needs. Taxes depend on the entity: a pass-through business pays no entity-level income tax, but its owners do, and lenders account for the cash that leaves to pay it. Addbacks in the seller's SDE that cannot be tied to the ledger are removed before any of this starts; which addbacks lenders accept covers the line between a documented addback and a hopeful one.
What that does to the loan size
Take the same business listed at three times SDE, a price of 3,000. A buyer who tests the deal on SDE assumes that 1,000 of cash flow, at a coverage ratio of 1.25x, supports 800 a year of loan payments. The lender runs the same test on 570, which supports about 456 a year at 1.25x, the ratio an SBA change of ownership must show on historical results from 1 October 2026. The buyer believed they had room for three-quarters more debt service than the business can actually carry.
Coverage is the binding test for most SBA 7(a) acquisitions, where the loan can run to 10 years for goodwill and the buyer needs equity of at least 10% of total project costs. From 1 October 2026, a change of ownership has to show 1.25x on historical results, which means on the seller's reported earnings after the lender's deductions, not on SDE and not on the buyer's projections.
Conventional senior cash-flow lenders to lower-middle-market companies add a second test: leverage. They commonly lend 2x to 3.5x EBITDA. On EBITDA of 780, that is 1,560 to 2,730 of senior debt. Applied to SDE by mistake, the same range would reach 3,500 and appear to cover the whole price. Applied correctly, even the top of the range leaves a gap that has to be filled with buyer equity, seller financing or a unitranche lender willing to stretch further.
A listing's SDE multiple describes the price. It says nothing about how much of that price a lender will fund.
Rebuild the number before you make an offer
The time to discover the lender's figure is before the letter of intent, when price and structure can still move. A buyer can do most of the lender's work from the listing materials and the tax returns:
- Start from the returns. Tie the broker's SDE to the business tax returns for the last two to three years and the target's latest full year. Where they differ, the reconciliation decides which earnings survive.
- Price every job the seller does. The seller may be the salesperson, estimator and bookkeeper at once. If you will not do all three, the business needs to pay for the ones you will not.
- Look for unpaid family labor. A spouse keeping the books without a salary is a cost the business will have after closing.
- Normalize related-party rent. If the seller owns the building and charges below-market rent, the new lease will cost more.
- Read the fixed-asset history. A seller who stopped replacing equipment in the years before a sale has lifted SDE by deferring costs the buyer will pay.
- Take out tax. Whatever the entity, cash for income tax leaves the business.
Then work backward from coverage: divide the cash flow that remains by 1.25x to find the annual debt service it supports, and compare that with the payments the sources and uses imply. If they do not meet, the offer needs a lower price, more equity, or a seller note, and it is far easier to say so in the letter of intent than after a lender has said it for you.
When SDE and EBITDA come close
The gap narrows in businesses where the owner is already mostly an owner: a general manager is on payroll at market, the owner's salary is modest and documented, and the business carries little equipment. In those cases the lender's deductions are small and the listing figure is closer to lendable cash flow. The gap is widest in businesses where the owner does a skilled job personally, such as a lead technician, a licensed professional or the only salesperson, because the market cost of replacing that person is high and sometimes has to be paid to more than one hire.
Transparent builds the lender's version of the figure into the financing model at the start of every acquisition file, and the underwriting memo shows each step from the seller's figure to cash available for debt service. How we underwrite explains the approach, and how much debt a business can carry goes further into sizing.
Common questions
- Do SBA lenders use SDE?
- No. SBA lenders build cash flow from the tax returns, replace the seller's compensation with a salary for the new operator, and test debt service coverage on what remains. SDE may appear in the listing, but it does not set the loan.
- What salary will the lender subtract?
- A market salary for the job the business needs done after closing, including payroll taxes and benefits. It depends on the role, the region and the size of the business, and it is not lowered because the buyer plans to draw less.
- If I work the same hours as the seller, why can't I keep the seller's SDE?
- You can take home something like it, but the lender still separates your pay from the business's ability to service debt. Your salary is a cost to the business before debt service, whoever draws it.
- Is a price at a low SDE multiple a safe price to finance?
- Not necessarily. The multiple is on the larger base. What matters is whether the cash flow after salary, capital spending and taxes covers the debt at the lender's required ratio.
- Are SDE and owner's cash flow the same thing?
- Usually. Brokers use several names for the same idea, earnings with one owner's pay added back, and definitions vary on details such as whether owner benefits are included. Always ask for the build, not just the total.
