🏡Home Equity Loan Calculator

Our home equity loan calculator helps you understand the true cost of borrowing against your home's equity before you commit. A home equity loan payment calculator that shows only the monthly payment obscures the total interest expense over the loan's life — which often rivals or exceeds the amount borrowed on longer terms. This tool shows the complete picture: monthly payment, total interest, your combined LTV, how much equity is available to borrow, and a full year-by-year amortization schedule.

Home Equity Loan vs. HELOC: Key Differences

A home equity loan and a home equity line of credit (HELOC) both let you borrow against your home's equity, but they work differently. A home equity loan is a second mortgage with a fixed loan amount, fixed interest rate, and fixed monthly payments — ideal when you know exactly how much you need and want payment certainty. A HELOC is a revolving credit line with a variable rate: you draw as needed during the draw period (typically 10 years), paying only interest, then repay the principal during the repayment period.

The draw period feature of HELOCs produces very low initial monthly payments (interest-only on only the amount drawn), but those payments can increase sharply when the repayment period begins and the rate resets. A $100,000 HELOC at 8% has an interest-only payment of $667 per month during the draw period. When the repayment period starts (assuming a 10-year repayment term), the payment jumps to approximately $1,213 — an 82% increase. This payment shock catches many HELOC borrowers off guard. This calculator models both structures so you can compare the payment profile before choosing.

Use a home equity loan when you need a specific sum for a defined purpose (a renovation, debt consolidation, tuition payment) and want the predictability of a fixed rate and payment. Use a HELOC when your borrowing needs are uncertain or variable over time, such as an ongoing renovation project with unpredictable costs or a business that may need periodic capital draws. Current rates as of 2024–2025 are similar for both products (roughly 8–9% for qualified borrowers), so the choice is primarily structural rather than rate-driven.

How Much Can You Borrow with a Home Equity Loan?

Your maximum borrowing amount is determined by your combined loan-to-value ratio (CLTV). Most lenders allow a maximum CLTV of 80–85%, meaning your first mortgage balance plus the home equity loan cannot exceed 80–85% of your home's appraised value. On a $400,000 home with a $200,000 remaining mortgage balance, a lender allowing 85% CLTV would permit borrowing up to $140,000 ($400,000 × 0.85 − $200,000 = $140,000).

Home equity requirements have tightened since 2020–2022. Many lenders also have minimum and maximum loan amounts (typically $10,000–$500,000) and may require a minimum equity threshold. Credit score requirements vary: scores above 700 qualify for the best rates; scores of 620–680 may qualify but at meaningfully higher rates; scores below 620 face limited options. Debt-to-income ratio (all monthly debt payments as a percentage of gross income) must typically be below 43–45% after including the new equity loan payment.

The interest rate on a home equity loan is also influenced by CLTV: borrowers at 60% CLTV typically receive lower rates than those at 80% CLTV because the lender has more collateral buffer. If your CLTV is high, consider paying down the first mortgage for 12–18 months to build equity before applying, which may result in a meaningfully better rate. Use our mortgage calculator to model how additional principal payments accelerate equity building.

Tax Deductibility of Home Equity Loan Interest

The Tax Cuts and Jobs Act of 2017 changed the deductibility rules for home equity loan interest significantly. Under current law (as of 2024), interest on a home equity loan is tax-deductible only if the loan proceeds are used to buy, build, or substantially improve the home securing the loan — the same property used as collateral. Interest on home equity loans used for other purposes (debt consolidation, car purchases, vacations, general expenses) is not deductible.

When the interest is deductible, the savings can be meaningful. At an 8% interest rate and a 24% federal marginal tax rate, the after-tax cost of the loan is effectively 6.08% for qualified uses. This makes home equity borrowing one of the more cost-effective forms of credit when the tax deduction applies and the proceeds are used appropriately. To claim the deduction, you must itemize deductions on Schedule A — the deduction is not available to those taking the standard deduction. Consult a tax professional for guidance specific to your situation and loan use.

When a Home Equity Loan Makes (and Doesn't Make) Financial Sense

A home equity loan makes strong financial sense for home improvements that increase property value: a kitchen renovation, bathroom addition, or energy efficiency upgrades that are expected to return 60–80% of their cost in added value at sale. The interest is potentially deductible, the improvements increase the asset securing the loan, and the fixed rate provides payment certainty over a defined payoff period.

Home equity loans also make sense for high-interest debt consolidation — consolidating $50,000 in credit card debt at 24% APR into a home equity loan at 8% saves approximately $8,000 per year in interest alone. The critical discipline required is to stop using the credit cards after consolidation; without that commitment, consolidation converts revolving debt into secured debt and adds risk without solving the underlying behavior.

A home equity loan does not make financial sense for short-term needs where a personal loan or savings would serve equally well without the risk, for discretionary spending that does not build lasting value (vacations, luxury purchases), or when your income or job security is uncertain. The fundamental risk of any home equity product is that your home is the collateral: default leads to foreclosure. This risk elevates the decision above the simple interest rate comparison that governs unsecured borrowing.
