Home Equity Loan Calculator: Payment, Equity and CLTV

Home Equity Loan Calculator

Estimate available equity, combined loan-to-value, fixed payment, interest, and closing costs.











How home equity and CLTV are calculated

Current nominal equity equals the estimated home value minus the mortgage balance. Combined loan-to-value (CLTV) divides the current mortgage plus the proposed home equity loan by the home value.

CLTV = (current mortgage + new home equity loan) ÷ home value × 100

The maximum new loan under the selected CLTV assumption equals home value multiplied by that limit, minus the current mortgage balance. This is an estimate, not a lender commitment.

Fixed home equity loan payment

A home equity loan typically provides a lump sum with a fixed payment. This calculator uses the standard amortization formula for the entered APR and term. If closing costs are financed, they increase the loan principal and its interest; otherwise they appear as upfront cash.

Home equity loan versus HELOC

This tool models a fixed, fully amortizing lump-sum loan. It does not model a home equity line of credit (HELOC), which may have a variable rate, changing draws, an interest-only draw period, and a later repayment period. Those cash-flow rules require a separate calculation.

Example

A $500,000 home with a $300,000 mortgage has $200,000 of nominal equity. At an 80% maximum CLTV assumption, total secured debt is limited to $400,000, leaving an estimated maximum new loan of $100,000 before lender-specific adjustments.

Important limits

Actual lending limits may be lower because of appraisal, credit, income, lien position, property type, fees, minimum draws, and lender policies. Nominal equity is not necessarily borrowable equity. The estimate excludes taxes, insurance, legal advice, and any effect on the first mortgage.
