Understanding Your Payment

Estimated monthly interest $343.75
Principal paid with interest-only payments $0.00
Remaining borrowed balance $50,000.00
Selected estimate period 12 months
Total estimated interest $4,125.00

How it is calculated:
Borrowed balance × (annual interest rate ÷ 100) ÷ 12.

During an interest-only period, payments cover interest and do not reduce the principal balance. The borrowed amount still needs to be repaid according to your HELOC agreement. Payments may increase when principal repayment begins.

Planning estimate only. This calculator assumes a constant balance and rate and divides annual interest into 12 equal months. Actual payments may differ based on daily interest accrual, billing-cycle length, changes in your balance or variable rate, fees, and minimum-payment requirements. The estimate period does not represent the bank’s available draw-period terms. Refer to your HELOC agreement for payment and repayment requirements.
