SBA loan basics
Short answer
SBA 7(a) loan interest rates are often comparable to, or slightly higher than, conventional bank loans for similarly qualified borrowers, because they include an allowable lender spread on top of a base rate.
SBA 7(a) loans have interest rate caps set by the SBA, typically based on the Prime Rate plus an allowed spread (e.g., Prime + 2.75%). While the SBA guaranty lowers risk for the bank, the rates are set to ensure the program is attractive to private lenders, so they are not subsidized to be exceptionally low.
If the Prime Rate is 8.5%, an SBA 7(a) loan might have a variable rate of Prime + 2.75%, resulting in an 11.25% interest rate. A conventional loan for a very strong borrower might be 9.5%, but for a borrower with higher risk (who would use SBA), the conventional rate could be even higher or unavailable.
