Estimate your available home equity and the monthly payment on a HELOC or home equity loan.
Our HELOC network minimum is $30,000.
Equity = max(0, home value − existing mortgage). Borrowing cap = max(0, home value × CLTV percentage/100 − existing mortgage). Modeled principal is the smaller of your desired amount and the cap; an estimate below $30,000 does not meet this marketplace’s HELOC request minimum. Repayment assumes a fully drawn balance amortized at a constant rate. Interest-only draw payments equal drawn principal × rate/1,200 and do not reduce the balance. Real HELOC draw periods, changing rates, fees, and repayment rules vary.
Methodology and assumptions
Monthly payment = P × r ÷ [1 − (1 + r)^(−n)], where P is the loan amount, r is the annual rate divided by 1,200, and n is the number of monthly payments. At 0% APR, payment = P ÷ n. Total repaid = payment × n; total interest = total repaid − P.
This estimate treats your APR as a fixed nominal annual rate with monthly interest and payments at the end of each month. Fees, insurance, taxes, variable-rate changes, and extra payments are excluded unless a tool explicitly includes them. A disclosed APR can include fees and may differ from the contractual interest rate. Values are rounded for display only. Estimates are not lending offers.
Example: $10,000 at 15% for 36 months is approximately $346.65 per month, $2,479.52 in interest, and $12,479.52 repaid, assuming no fees.

For example only. Illustrative only. Actual HELOC/home equity offers depend on appraisal, credit profile, occupancy, and lender guidelines. HELOCs typically carry variable rates that can change over time; home equity loans are typically fixed. Your home secures the loan and can be foreclosed on if you default.
Understanding equity, CLTV, and rates
Equity is the difference between your home's current value and what you still owe on the mortgage. CLTV (combined loan-to-value) is the total of all mortgage debt divided by home value. Most HELOC and home equity loan lenders cap CLTV at 80%–90% — that's the ceiling on total borrowable amount.
HELOCs typically carry variable rates that move with the prime rate; home equity loans are usually fixed. Your home is collateral for either product — missed payments can lead to foreclosure. Compare secured (HELOC / home equity) against unsecured (personal loan) options carefully.
