Formula & Methodology
Interest-Only = Balance × Rate / 12; Repayment = PMT(balance, rate, repayment years)
HELOCs have a draw period (interest-only) followed by a repayment period (fully amortizing).
Frequently Asked Questions
What happens at the end of the HELOC draw period?
The HELOC enters repayment: you can no longer draw, and payments increase to cover both principal and interest.
