Interest-only on constant drawn balance. Ignores draws/paydowns, variable rates, fees, and required payments. Not a HELOC offer.
Interest-only vs amortizing reality
Many HELOCs start interest-focused during a draw period. This tool prices interest on a constant draw.
Variable indexes can change the APR mid-stream — treat outputs as snapshots.
HELOC vs cash-out refinance
HELOCs keep the first mortgage intact; cash-out refinances replace it. Break-even logic differs — use both calculators.
Fees, closing costs, and lien priority are product-specific.
