Model a Business Line of Credit Month by Month
Estimate the first payment, interest-only minimum, amortizing payment, fixed-principal schedule or custom-payment payoff for one business credit-line draw. Fees and a rate adjustment remain visible instead of being hidden inside a generic loan formula.

How a business line of credit payment is calculated
Interest is calculated from the outstanding revolving balance. Interest-only mode pays accrued interest but does not reduce principal unless extra principal is entered. Amortizing mode uses the standard level-payment formula for the chosen payoff term. Fixed-principal mode divides the opening balance by the term and adds declining interest. The simulator then applies fees, additional draws and extra principal month by month.
Why a line of credit is not a standard term loan
A line can be drawn, repaid and reused, and its rate may change. This calculator therefore separates the first payment, minimum interest-only amount, projected payoff time, total interest, draw fee and annual maintenance fees.
Can the custom payment fail to pay off the balance?
Yes. If the payment does not cover interest and new draws, the balance grows. The result flags negative amortization rather than reporting a false payoff date.
