Business loan calculator

A business loan payment depends on the amount, the interest rate and the term. A $150,000 loan at 9.5% for 10 years costs about $1,941 a month and $82,916 in total interest. Enter your loan details, including any upfront fees like an upfront SBA fee, to see your payment and the total cost.

    How is a loan payment calculated?

    Fixed-rate business loans, including most SBA 7(a) and equipment loans, use a standard amortization formula: the same payment each month, with more of it going to interest early on and more to principal later. The calculator uses that formula.

    What else adds to the cost?

    Origination fees, upfront SBA fees, closing costs and any required insurance. Lenders often quote the interest rate, not the true yearly cost, so add fees to compare offers fairly. Variable-rate loans change as rates move, and lines of credit charge interest only on what you draw.

    Is loan interest tax deductible?

    Interest on money borrowed for the business is generally deductible, subject to limits for larger businesses. The principal you repay isn't an expense, but whatever you bought with it may be depreciated or written off. Lenders will ask for clean books and recent returns, which our bookkeeping and business tax returns keep ready.
