About this calculator

A HELOC has two phases. During the draw period (typically 10 years), you can borrow against the line and only owe monthly interest on what's outstanding — payments are small but the balance never drops unless you pay extra. When draw ends, the line converts to a fully amortizing loan over the repayment period (10-20 years), and your payment can jump 2-3×. HELOCs are usually variable-rate at Prime + 0-2%, so a Fed rate move shows up on next month's statement.

Frequently asked

You're only paying interest, not principal. The balance stays flat (or grows if you borrow more) until repayment phase begins.
