What a home equity loan is
CFPB describes a home equity loan as a lump sum secured by home equity, usually with a fixed rate. It is separate from the existing mortgage, whose payment remains due.
Equity and combined LTV
Equity is estimated value minus existing mortgage debt. Combined LTV compares both loans with value and is a screening measure, not an approval decision.
equity = value − mortgage balanceCLTV = (mortgage + new loan) ÷ value × 100Payment and total interest
The new loan is amortized in equal monthly payments. The result separates principal, interest and upfront costs and includes every schedule row.
Closing costs and APR
Upfront costs raise the economic cost even when they are paid in cash. APR may reflect certain charges; compare lender disclosures rather than payment alone.
Risk and estimate limits
Because the home is collateral, missed payments can put it at risk. Actual appraisal, liens, lender CLTV limits, taxes and insurance requirements are outside this model.
