Frequently Asked Questions

How does the Smallbiz Loan Calculator work?

Enter your loan balance, interest rate, and term. The calculator uses standard amortization formulas to show your monthly payment, total interest paid, and payoff timeline.

How can I pay off my loan faster?

Making extra payments toward principal reduces your balance faster and saves significant interest. Use the calculator to see exactly how much extra you need to pay each month to hit your target payoff date.

What interest rate should I enter?

Enter the APR (Annual Percentage Rate) from your loan agreement, not the APY. Your most recent statement or lender portal will show this.

Is my financial data secure?

Yes — all calculations happen in your browser. No data is transmitted or stored anywhere.
