Fixed-loan and borrowing-capacity estimates

Home Equity Loan Calculator

Estimate how much a combined-LTV limit may leave available to borrow, then calculate payments on your requested loan. See total interest and equity remaining immediately after borrowing.

Home and loan details

Include existing liens once; do not repeat the first mortgage under other liens. For an existing HELOC, use the balance or credit-limit figure your lender requires. The 85% default is an editable assumption, not a universal lending limit.

Enter the proposed loan's fixed interest rate, not an APR that includes fees. The requested loan is additional debt; this model does not use proceeds to pay off existing liens.

How the estimate works

Maximum combined debt = home value × assumed combined-LTV percentage, rounded down to cents. Additional borrowing capacity = the larger of zero or maximum combined debt minus the first mortgage and other liens. A request above this capacity is flagged; its payment is still calculated as a hypothetical loan without reducing your entered amount.

Current equity = home value minus existing liens. Remaining equity subtracts the requested new loan as well. Combined LTV = (first mortgage + other liens + requested loan) / home value × 100. Negative equity is shown rather than hidden. These are immediate equity estimates, assuming the entered home value and lien balances remain unchanged.

Monthly rate r = fixed annual rate / 12. Payment = requested loan × r / (1 − (1 + r)^(−n)), where n is the term in months. At zero interest, payment = loan / n. The regular payment rounds up to cents, monthly interest rounds to cents, and the final payment clears the remaining balance. Total interest is the sum of monthly interest charges.

Home equity loan versus HELOC

A home equity loan normally provides a lump sum with a fixed repayment schedule and usually a fixed rate. A HELOC is a revolving credit line that permits draws under its terms. This calculator models a fully amortizing fixed-rate home equity loan; use the HELOC Calculator for draw and repayment-period scenarios.

Borrowing capacity depends on lender valuation, credit, income, debt obligations, lien treatment and product limits as well as CLTV. Fees, financed closing costs, taxes, insurance, variable rates, balloon payments, extra payments and tax deductions are excluded. The displayed payment does not include your first-mortgage payment. Your home secures this type of borrowing.
