Business loan calculator

See the real cost of borrowing before you sign: monthly payment, total interest, fees and how fast the balance falls.

Typical small business term loans run 6–60 months. Fees are often 0–5% of the amount.

How the payment is calculated

Most term loans use a standard amortizing formula: Payment = P × r ÷ (1 − (1 + r)−n), where P is the amount borrowed, r is the monthly interest rate (annual rate ÷ 12) and n is the number of monthly payments. Early payments are mostly interest; later payments are mostly principal, which is why the table above shows interest shrinking each year.

Look past the monthly payment

A longer term lowers the monthly payment but raises total interest. Before choosing, compare total cost of the loan (interest plus fees) across two or three terms. If you can comfortably afford a shorter term, it is almost always cheaper.

Watch for factor rates. Merchant cash advances and some short-term products quote a "factor rate" (e.g. 1.3) instead of an interest rate. A 1.3 factor repaid over six months can equal an annual percentage rate well above 60%. Convert everything to APR before you compare.

What lenders look at

  • Time in business — many lenders want 1–2 years of history.
  • Revenue — monthly deposits on bank statements.
  • Credit — personal and, increasingly, business credit scores.
  • Debt service coverage — whether cash flow covers the new payment, usually by 1.25× or more.
