HELOC & home equity calculator
Estimate the line and pressure-test the payment.
Explore how value, the existing mortgage, a combined-loan-to-value assumption, the credit line, the draw, and a variable rate work together.
Home equity inputs
Model the available line.
Start with an estimated value and current first-mortgage balance.
The combined-loan-to-value limit is an editable modeling assumption, not a program promise. Property value, credit, income, lien position, and lender guidelines affect eligibility.

Why both payments?
Many HELOCs have a draw period followed by repayment. Rates are commonly variable, so the actual payment can change. Review the note, margin, index, fees, draw period, and repayment terms before deciding.
Your next move
A HELOC can preserve your first mortgage, but that does not automatically make it the best equity option.
Compare the variable-rate line with a home-equity loan and cash-out refinance using your complete scenario.
