Target Audience Application

Guide clients on capital preservation vs. loan origination fees when scaling business operations.
Assess the true lifetime interest expense of 25-year fixed CDC debentures versus adjustable-rate conventional commercial loans.
SBA 504 Blended Rate & Fee Structure
Senior Bank Note: 50% of Project (Market Bank Rate)CDC Debenture Note: 40% of Project (SBA 10-Yr / 25-Yr Fixed Debenture)Borrower Equity: 10% (15% for special-purpose or startup)Blended Rate = 0.50 × Bank Rate + 0.40 × (CDC Rate + Annual Servicing Fees)
Loan Program Decision Rules
- Choose SBA 504: For owner-occupied commercial real estate (51%+ occupancy) or heavy equipment purchases where a 25-year fixed rate and 10% down payment preserve cash.
- Choose SBA 7(a): For working capital, business acquisitions, partner buyouts, or projects under $5,000,000 requiring flexible collateral terms.
- Choose Conventional: If the business has 20% to 25% equity down payment and strong balance-sheet history to avoid SBA upfront guarantee fees.
