Equity constraint
Your verified liquid assets determine how large a purchase price you can equity-inject into. At 10% down, every $100,000 in cash supports up to $1,000,000 in purchase price.
SBA 7(a) acquisition buying range
How Much Business Can I Buy With an SBA Loan?
Your SBA buying range is not what you want to buy — it is what your cash and the target business's cash flow can support. Here is how to calculate both limits and find the binding constraint.
Equity and DSCR constraints
SBA 7(a) up to $5M

The two limits
Your buying range has two ceilings
Every SBA acquisition deal faces two independent constraints. Your cash sets the maximum purchase price your equity can support. The business's cash flow sets the maximum loan the lender will approve. The binding constraint — the lower of the two — is your actual ceiling. Many buyers focus only on their cash, without checking whether the target's DSCR supports the debt. Many others target businesses based on cash flow without verifying they have enough cash for the equity injection and closing costs.
DSCR constraint
The target business's annual cash flow determines the maximum loan it can support under the selected lender's debt-service analysis. The example below uses a 1.25x planning assumption. A business generating $200,000 in SDE supports roughly $1.2M in SBA debt.
The binding constraint
Whichever ceiling is lower is your actual buying range. If your cash supports $1M but DSCR only supports $800K in debt, the deal must be structured at or below $900K (with 10% down).
Calculating your equity ceiling
How cash sets your maximum purchase price
The SBA 7(a) program requires a minimum 10% equity injection from the buyer's verified liquid assets. That floor — established in SBA SOP 50 10 — is the starting point for your equity constraint calculation. But total cash to close is always more than just the down payment.
- The basic formula: Maximum purchase price (equity-based) = verified liquid assets ÷ 10%. A buyer with $150,000 in verified cash can support up to a $1,500,000 purchase price before accounting for closing costs and reserves.
- Adjust for closing costs: SBA guarantee fees, lender origination fees, appraisal, title, and legal costs typically add 3–6% to total cash at closing. A buyer targeting a $1,000,000 deal needs approximately $100,000 for the equity injection plus $30,000–$60,000 for closing costs — meaning $130,000–$160,000 in total liquid assets, not $100,000.
- Reserve requirement: After closing, most lenders want to see the buyer retain 1–3 months of operating expenses in liquid assets. This further reduces the maximum purchase price the equity can support at any given cash level.
- Seller-debt equity credit: When a 10% injection is required, seller debt may account for no more than half of that requirement only if it is on full standby for the life of the SBA loan. The calculation is based on total project cost, and the lender must confirm the final treatment. Other seller debt does not replace the required injection and may add debt service.
$100K cash, 10% down
Max purchase price (before fees): $1,000,000. Subtract closing costs and reserves, realistic ceiling is closer to $750,000–$850,000.
$100K cash, 5% + seller note
Max purchase price: $2,000,000. Requires seller agreement to a full-standby note and sufficient business cash flow to support a larger SBA loan.
$200K cash, 10% down
Max purchase price: $2,000,000 before fees. Realistic ceiling accounting for costs and reserves is $1,500,000–$1,700,000.
Calculating the DSCR ceiling
How business cash flow sets your maximum loan
Debt service coverage ratio (DSCR) measures how many dollars of annual cash flow the business generates for every dollar of annual loan payments. Many SBA acquisition lenders use 1.25x as an initial planning benchmark, but actual lender policy and eligible cash flow vary. The selected coverage requirement helps determine maximum annual debt service and, from that, an indicative loan principal.
- The DSCR formula: DSCR = Annual SDE ÷ Annual debt service (principal + interest). At 1.25x DSCR, the maximum annual debt service = SDE ÷ 1.25. If the business generates $250,000 in SDE, the maximum supportable annual debt service is $200,000.
- Converting debt service to loan principal: The relationship between annual debt service and loan principal depends on the loan term and interest rate. At a 7% interest rate and 10-year term, $200,000 in annual debt service supports approximately $1,400,000 in principal. At a 7% rate and 25-year term (available for real estate-secured deals), the same debt service supports much more principal.
- The SBA $5M cap: SBA 7(a) loans are capped at $5,000,000. Even if the DSCR math supports a larger loan, the maximum SBA loan is $5M. Above that threshold, buyers must bridge the gap with additional equity, seller financing, or alternative lenders.
- Existing debt service: If the buyer has other business or personal debt (existing loans, alimony, child support obligations that lenders may include), those annual payments reduce the DSCR available for the acquisition loan. The lender calculates DSCR on total annual obligations — not just the new SBA loan.
- What counts as SDE: Lenders use only defensible, documented cash flow. Add-backs that don't appear in the tax returns or can't be specifically documented are generally excluded. An optimistic seller SDE figure is almost always higher than what a lender will underwrite to.
Worked example
Finding the binding constraint
Here is how to apply both calculations to a specific buyer and target deal to determine actual buying range.
- Buyer's verified liquid assets: $180,000. Equity constraint: $180,000 ÷ 10% = $1,800,000 maximum purchase price. After closing costs (estimated $54,000 at 3%) and a 2-month operating reserve ($30,000), the realistic equity-supported purchase price is closer to $1,500,000–$1,600,000.
- Target business SDE: $220,000 (documented in tax returns). Maximum annual debt service under the illustrative 1.25x planning assumption: $220,000 ÷ 1.25 = $176,000 per year.
- Maximum loan principal: At 7% interest and 10-year term, $176,000 annual debt service translates to approximately $1,240,000 in loan principal. At 10% equity injection, the maximum purchase price is $1,240,000 ÷ 90% = approximately $1,378,000.
- The binding constraint: The DSCR ceiling ($1,378,000) is lower than the equity ceiling (~$1,600,000). The buyer's actual SBA buying range for this target is approximately $1,300,000–$1,400,000. Targeting a business priced at $1,800,000 — which the equity could technically support — would fail on DSCR.
- The solution: Either find a target with higher SDE (above $280,000 for a $1.8M price under the illustrative 1.25x assumption), negotiate a lower purchase price, or add a seller note to reduce the SBA loan amount and improve DSCR on the debt that remains.
