SBA upfront guaranty feeUsually financed into the loan$11,250
Guaranteed portion of the loan75% guarantee$375,000

Total interest paid$326,500
Upfront fee plus interestWhat the financing costs beyond the money borrowed$337,750
Debt service coverage (DSCR)$82,650 annual payments1.45x

Most lenders look for a DSCR of about 1.15 to 1.25 after paying yourself a market salary. Below 1.00 the business cannot service the debt from its own cash flow.

What this does not include

  • A down payment. Buyers typically put 10–20% of the purchase price in, from savings, a home equity line, or a retirement rollover.
  • Lender and third-party costs: appraisal, environmental report, franchise feasibility study, legal and closing fees.
  • Seller financing, earn-outs, and the working capital left in the business at closing.
