Small Business Administration (SBA) loans are government-backed financing options designed to help small businesses access capital. Our SBA loan calculator helps you estimate monthly payments, understand guarantee fees, and compare different SBA loan programs before applying. By entering your loan amount, interest rate, and term, you'll see the true cost of SBA financing including the SBA guarantee fee that most borrowers must pay.
SBA loans are partially guaranteed by the U.S. Small Business Administration, reducing risk for lenders and enabling more favorable terms for borrowers. The SBA doesn't lend directly—instead, it guarantees a portion of loans made by participating banks, credit unions, and online lenders. This guarantee ranges from 40% to 85% depending on the loan type. Because of this backing, SBA loans typically offer lower down payments (10-20%), longer repayment terms (up to 25 years), and competitive interest rates compared to conventional business loans.

The SBA guarantee fee is a one-time fee paid by borrowers to the SBA for guaranteeing the loan. For 7(a) loans, it's 2% of the guaranteed portion for loans up to $1M, 3% plus 0.25% on the portion over $1M for loans $1-2M, and 3.5% plus 0.25% for loans over $2M. This fee is typically rolled into the loan amount.
