Weighted 0–100How to analyze a business acquisition
Buying a business is not a valuation exercise — it is a cash flow exercise. A fair price you cannot finance is a bad deal, and a high price with the right structure can still work. This analyzer models both sides at once: what the business is worth, and whether the deal as structured actually pays you.
1. Start with SDE, not revenue
Seller's Discretionary Earnings (SDE) is net profit plus the current owner's salary, personal expenses run through the business, interest, depreciation, and any genuine one-time costs. It represents the total financial benefit to a single working owner. Small businesses are priced as a multiple of SDE; larger ones move to EBITDA, which does not add back an owner's salary.
2. Check that the deal services its own debt
The Debt Service Coverage Ratio (DSCR) is the single number a lender cares about most. It compares cash available after you replace the owner against the annual loan payments. Below 1.00 the business cannot pay its own debt. Most SBA lenders require at least 1.25×, and experienced buyers look for 1.50× or better so that a bad quarter is not an emergency.
3. Measure the return on your own cash
Cash-on-cash return divides the cash the business puts in your pocket in year one by the cash you actually had to bring to closing — down payment, closing costs, and the working capital you leave in the business. It is the honest measure of what the deal does for you, and it is the reason leverage matters: the same business at the same price produces a very different return depending on how it is financed.
4. Know how much room you have to be wrong
The revenue cushion answers the question every buyer should ask before signing: how far can revenue fall before this deal is in trouble? Under 10% is fragile. A business with concentrated customers, no recurring revenue, and a thin cushion is a deal where one lost account ends the story.
What makes a deal score well
The score is weighted toward survival first and returns second, because a deal that cannot service its debt fails regardless of how good the return looked on paper:
- Debt coverage (26%) — DSCR against the 1.25× lender threshold
- Cash-on-cash return (22%) — year-one cash yield on invested capital
- Purchase price (18%) — the multiple paid versus the industry band
- Business quality (20%) — customer concentration, owner dependence, recurring revenue, tenure and trend
- Downside cushion (14%) — tolerable revenue decline before coverage breaks
A deal with DSCR under 1.00 is capped at 32 no matter how attractive its other metrics look, and a deal producing no positive buyer cash flow in year one is capped at 30.
Common structures
Most main-street acquisitions in the United States are financed through an SBA 7(a) loan: roughly 10% buyer equity, 10% seller note on standby, and the balance from the bank over 10 years. Bringing more cash lowers debt service and raises DSCR but lowers your cash-on-cash return. A larger seller note keeps the seller invested in a clean handover and is usually cheaper than bank debt.
