What a Small-Business Loan Actually Costs
The monthly payment tells you whether a loan fits this month; total interest tells you the price of the term. Compare both, then test whether a small extra payment creates a useful payoff improvement.
Read the payment and the term together
A longer term can lower the required payment but generally raises total interest because the balance stays outstanding longer. A lower payment is not automatically a lower-cost loan.
Use the same principal, APR, and term from a lender’s offer first. Then test alternatives only after you know which fees, collateral, prepayment rules, and rate conditions apply.
Use extras as a cash-flow decision
Extra principal can shorten payoff and reduce interest when the agreement permits it. Do not assume every loan treats extra payments the same way; confirm prepayment terms.
This tool models standard amortization and does not include origination fees, variable rates, late charges, tax treatment, or lender-specific schedules.
Run two scenarios
Use the assumptions that fit your decision.
