How HELOC Payments Structure Works
A Home Equity Line of Credit (HELOC) acts like a massive credit card tied to the equity of your home. It features a unique two-phase lifecycle: the 'Draw Period' and the 'Repayment Period'.
During the initial Draw Period (usually 10 years), you can borrow against your credit limit, and your monthly payments are typically purely 'Interest-Only' based on the balance you've drawn.
Once the Draw Period ends, you enter the Repayment Period (usually 20 years). You can no longer draw funds, and your remaining balance is forcefully amortized into mandatory principal and interest payments. This calculator demonstrates the dramatic 'Payment Shock' that occurs during this transition so you can budget accordingly.
Frequently Asked Questions
No, almost all HELOCs have variable interest rates tied to the Prime Rate. If the Federal Reserve raises rates, your monthly HELOC payment will increase immediately during both the draw and repayment periods.
Absolutely. Making principal payments during the Draw Period replenishes your available credit limit and lowers the amount of interest you will be charged on your next monthly statement.
