Home Equity Loan Calculator

A home equity loan is a closed-end second lien: the borrower receives a lump sum secured by the residence and repays it on a fixed amortization schedule. The payment comes from the standard annuity formula, P times r times (1 plus r) to the n, divided by (1 plus r) to the n minus one, where r is the annual rate divided by twelve and n is the term in months. The borrowing ceiling is set by combined loan-to-value: lenders take the home value, multiply by a maximum CLTV that typically falls between 80 and 90 percent, and subtract the existing first mortgage balance. On a 400,000 dollar home with a 250,000 dollar mortgage and an 85 percent limit, that leaves 90,000 dollars of borrowable equity even though nominal equity is 150,000 dollars. Because the lien sits behind the first mortgage and is repaid only after it in a foreclosure, rates run several points above first-mortgage rates, commonly in the 7 to 10 percent range in recent years, with 5, 10, 15, and 20 year terms most common. Underwriting also considers credit score, usually 620 or higher and better pricing above 700, and a debt-to-income ratio generally capped near 43 percent. Two limitations matter. Interest is deductible only when proceeds buy, build, or substantially improve the home securing the loan, a restriction imposed by the Tax Cuts and Jobs Act, and the schedule here assumes a fixed rate with no missed payments, no prepayment, and no change in the appraised value that determines available equity.

Borrowing against home equity was uncommon in the United States before the 1980s, partly because second mortgages carried a reputation as distress finance and partly because there was no tax reason to prefer them. That changed with the Tax Reform Act of 1986, which phased out the deduction for consumer interest on credit cards, auto loans, and personal loans while preserving deductibility for interest on debt secured by a residence. Lenders responded almost immediately by marketing home equity loans and lines of credit as a tax-favored substitute for consumer credit, and volumes expanded rapidly through the late 1980s and 1990s. Two earlier statutes shaped the product's mechanics. The Depository Institutions Deregulation and Monetary Control Act of 1980 preempted state usury ceilings on residential mortgage lending, making higher-rate junior liens legal to originate, and the Alternative Mortgage Transaction Parity Act of 1982 broadened permissible loan structures. Consumer protection followed the growth: the Home Ownership and Equity Protection Act of 1994 amended the Truth in Lending Act to regulate high-cost home equity loans after documented abuses, and Regulation Z has long granted a three-day right of rescission on a lien against a principal residence. Home equity borrowing peaked before the 2007 to 2009 housing crisis, when falling prices erased the collateral behind many second liens, and lenders subsequently tightened combined loan-to-value limits, which is why 80 to 85 percent is now a typical ceiling.
