SBA Loan Payment Calculator

How SBA Loans Work

SBA loans are partially guaranteed by the U.S. Small Business Administration, which reduces risk for lenders and results in lower rates and longer terms for borrowers. The SBA does not lend directly. Instead, it guarantees a portion of the loan made by an approved bank or lender. That guarantee costs the borrower fees, but those fees are small compared to the interest savings over the life of the loan. This calculator factors in all SBA-specific fees so you see the true cost, not just the payment.

SBA 7(a) vs 504: Which Program Fits?

The 7(a) program is the SBA's most flexible option. Use it for working capital, equipment, real estate, acquisitions, or refinancing existing debt. Loans go up to $5 million with terms up to 25 years for real estate and 10 years for most other purposes. The 504 program is specifically for fixed assets: commercial real estate or major equipment purchases. It uses a three-party structure where you put 10% down, a bank covers 50%, and an SBA-backed CDC covers 40% at a below-market fixed rate. The 504 often delivers lower total cost for qualifying projects but cannot be used for working capital. Compare both programs side by side with this calculator, then use our standard loan calculator to model conventional alternatives.

Understanding SBA Guarantee Fees

The SBA charges two types of fees on 7(a) loans. The upfront guarantee fee is a percentage of the guaranteed portion of the loan, ranging from 2.0% for loans up to $150,000 to 3.75% for loans over $1 million. This fee is typically financed into the loan so you do not pay it out of pocket. The annual servicing fee is 0.55% of the outstanding guaranteed balance, included in your monthly payment by the lender. On a $500,000 loan, the upfront fee might be around $11,250 and the servicing fee adds roughly $100 per month in the early years. Even with these fees, total cost is usually significantly lower than a conventional business term loan because the interest rate itself is lower.

Getting Approved for an SBA Loan

SBA lenders typically look for a personal credit score of 680 or higher, at least 2 years in business, and a debt service coverage ratio (DSCR) of 1.15 or better. Check your DSCR before applying to see where you stand. Collateral helps but is not always required for 7(a) loans. The process takes 30 to 90 days, longer for 504 loans because of the CDC approval layer. If you need funds faster, conventional lines of credit and term loans can fund in days.
