If you are evaluating SBA loan options, one of the first questions you will face is: what will this actually cost each month — and over the life of the loan? SBA loans offer below-market rates and longer repayment terms than conventional business loans, but they come with guarantee fees that add to your upfront closing costs. Understanding the full picture before you apply helps you compare lenders and choose the right program.
The calculator below covers all four major SBA loan programs: the 7(a) Standard (up to $5 million), the 7(a) Small ($500,000 or less), the SBA 504 (for fixed assets like real estate and equipment, up to $5.5 million), and the SBA Microloan (up to $50,000 through nonprofit intermediaries).
SBA loan terms and fees are set by the SBA and change periodically. Verify current rates at sba.gov before applying. Calculator uses 2024 guarantee fee schedule.
How SBA Loan Fees Work
The SBA guarantee fee is not charged by your lender — it is a fee the SBA collects to fund the guarantee program. You pay it at closing, and it is based on the guaranteed portion of your loan, not the full loan amount.
For 7(a) loans, the guaranteed portion is 85% for loans up to $150,000 and 75% for larger loans. So on a $500,000 loan, the SBA guarantees $375,000 (75%), and the 3.0% fee applies to that $375,000 — not the full loan balance.
Lenders are allowed to roll the guarantee fee into your loan balance, so you may not need to pay it out-of-pocket at closing. However, financing the fee means you pay interest on it over the loan term, slightly increasing your total cost.
Choosing the Right SBA Program
SBA 7(a) Standard is the most flexible SBA program. Use it for working capital, equipment, inventory, business acquisition, or real estate. Terms up to 25 years for real estate, 10 years for everything else.
SBA 7(a) Small applies to loans of $500,000 or less and often has a simpler application process. Rates and terms are the same as standard 7(a). Preferred Lenders (PLP lenders) can approve these quickly.
SBA 504 is designed for major fixed assets — commercial real estate and heavy equipment. It is structured as two loans: roughly 50% from a conventional lender and 40% from a Certified Development Company (CDC) backed by an SBA debenture. The 504 rate on the CDC portion is fixed and typically lower than 7(a) rates, but the structure is more complex.
SBA Microloan provides up to $50,000 through nonprofit intermediaries. These lenders often serve startups, women-owned, minority-owned, and rural businesses that do not yet qualify for bank financing. Rates are higher (8–13% APR typically), but terms and mentoring support make them accessible for early-stage businesses.
What Lenders Evaluate
Beyond credit scores, SBA lenders use the “5 C’s” framework: Character (your credit and business history), Capacity (cash flow to repay — lenders look for a debt service coverage ratio above 1.25), Capital (your equity contribution — typically 10–20% for SBA loans), Collateral (business and personal assets pledged), and Conditions (industry, economic environment, loan purpose).
The SBA requires a personal guarantee from all owners with 20% or more ownership stake. If your business cannot repay, you are personally liable. For real estate loans, the property itself typically serves as primary collateral.
Use the calculator results to estimate your debt service coverage ratio before you apply: take your business’s annual net operating income and divide it by your projected annual SBA loan payments. A ratio above 1.25 is generally required; above 1.5 is stronger.
