Understanding a fixed-rate business loan payment

Learn how principal, interest, term, and fees affect an estimated business loan repayment.

What the calculator assumes

The model uses equal monthly payments, a fixed nominal annual interest rate divided by twelve, and payments at the end of each month. There are no added fees or insurance charges. It does not model interest-only periods, balloon payments, variable rates, daily interest, or payment holidays.

How each payment is split

Each month, interest is calculated on the outstanding balance. The rest of the payment reduces principal. Early payments generally contain more interest because the outstanding balance is larger. Later payments reduce more principal. The repayment schedule shows this progression using unrounded internal amounts.

Read the monthly payment and total together

A longer term may reduce the monthly payment while increasing total interest. For example, borrowing 25,000 at a nominal annual rate of 7.5% over 36 months gives an estimated payment of 777.66 and total repayment of about 27,995.60 before fees. Rounding each actual installment may change the final payment slightly.

Include costs outside the model

Arrangement fees, required insurance, account charges, security costs, and early repayment terms may affect the actual cost. The entered nominal rate is not necessarily APR or another regulated cost measure. Compare lender disclosures on a consistent basis and obtain a full repayment schedule from the lender.

Check cash flow before committing

Compare required payments with realistic cash available after operating expenses. Test weaker sales and higher costs, and consider when customers actually pay invoices. A calculator result does not establish affordability or eligibility and is not a loan offer.
