An SBA loan calculator can help buyers quickly estimate whether a business acquisition may fit their budget before they speak with a lender. Enter a purchase price, down payment, interest rate, term, fees, and working capital reserve to review estimated monthly payments and cash needed to close.

This tool is for planning only and does not represent loan approval, lender terms, tax advice, legal advice, or a final financing offer. Before relying on the numbers, review SBA loan qualifications, compare active businesses for sale, and complete a business due diligence checklist.

  • Down payment, closing costs, reserves, and working capital needs.
  • Debt service coverage and lender underwriting expectations.
  • Seller financing, collateral, credit strength, and buyer experience.
  • Lease terms, business records, valuation, and transition risk.
  • How financing affects offer price, timing, and negotiation strategy.
