🏢 SBA Loan Calculator
Calculate your SBA 7(a) or 504 loan payments including principal, interest, and guarantee fees. Get a complete amortization schedule and total cost analysis for your small business financing needs.
What Is an SBA Loan Calculator?
An SBA loan calculator helps you estimate the monthly payments and total cost of an SBA-backed small business loan. SBA loans offer longer terms and lower down payments than conventional business loans because the SBA guarantees a portion of the loan, reducing risk for lenders.
This calculator supports two primary SBA programs:
- SBA 7(a) Standard , the most common SBA loan, up to $5 million, for general business purposes including working capital, equipment, and real estate. Terms up to 25 years for real estate, 10 years for other purposes.
- SBA 504 (CDC) , for major fixed assets like real estate and heavy equipment. Up to $5.5 million, with fixed rates on the CDC portion and terms of 10, 20, or 25 years.
How Does the SBA Loan Calculator Work?
The calculator uses the standard amortization formula:
Monthly Payment = P × [r(1+r)n] / [(1+r)n − 1]
Where: P = principal, r = monthly interest rate, n = number of payments
The calculator also includes:
- Upfront Guarantee Fee , a percentage of the SBA-guaranteed portion, typically 2-3.75% for loans over $150,000.
- Annual Service Fee , 0.55% of the outstanding guaranteed balance (paid by lender, not borrower).
- Full Amortization Schedule , showing every payment over the life of the loan.
