What is standard interest rate for a small business loan?

Commercial bank and SBA 7(a) loan interest rates typically range from 6% to 12% depending on creditworthiness, collateral, and prevailing benchmark interest rates.

How does loan term length affect total cost?

Longer terms lower your monthly debt service payments but increase total lifetime interest paid. Shorter terms require higher monthly payments but reduce interest expense.

What is an origination fee on a business loan?

An origination fee is an upfront fee charged by commercial lenders to cover loan evaluation, underwriting, and processing, usually deducted from the disbursed loan amount.

What is the Debt Service Coverage Ratio (DSCR)?

Lenders use DSCR (Net Operating Income / Total Debt Service) to measure repayment ability. Most lenders require a DSCR of at least 1.25x.

Can extra principal payments shorten the loan term?

Yes. Making additional principal payments reduces the compounding balance, saving substantial interest and shortening payoff time, assuming no prepayment penalties exist.

How do commercial loans differ from SBA loans?

SBA loans are partially guaranteed by the U.S. Small Business Administration, allowing banks to offer lower interest rates and longer repayment terms to eligible businesses.
