Home Equity in 2026: How to Calculate It, How to Access It, and When Not To

American homeowners are sitting on a record amount of home equity. Rising property values over the past several years have pushed the total tappable equity held by US mortgage borrowers above four trillion dollars, according to recent industry estimates. For many households, the equity in their home represents their single largest financial asset. That makes understanding how to access it, when to access it, and when to leave it alone one of the more consequential decisions in personal finance. Accessing home equity costs real money and carries real risk, but used strategically, it can fund renovations that increase property value, consolidate high interest debt, or cover expenses that would otherwise require withdrawing from retirement accounts at the worst possible time.

How Home Equity Is Calculated

Home equity is the difference between your home's current market value and the total amount you owe on all loans secured by that property. If your home is worth $450,000 and you owe $280,000 on your mortgage, your equity is $170,000. The calculation is simple, but the inputs are harder to know precisely. Your balance is easy to find on your mortgage statement. Your home's current value requires an appraisal, a formal broker price opinion, or a reasonably reliable automated valuation model from a real estate site, with the understanding that automated estimates often carry meaningful error ranges.

Lenders use their own appraisal when you apply for a home equity product, and their number is what actually drives how much you can borrow. Getting a rough sense of your equity before applying is useful for planning, but do not be surprised if the lender's appraised value differs from what you see on real estate websites. Use our home equity calculator to estimate your available equity and how it translates to potential borrowing capacity.

Home Equity Loan vs HELOC: The Core Differences

A home equity loan gives you a lump sum at a fixed interest rate repaid over a set term, typically five to fifteen years. You know exactly what your monthly payment will be from the start. This predictability makes home equity loans well-suited for single large expenditures where you know the amount: a roof replacement, a medical bill, paying off a specific debt. The rate is generally slightly higher than a first mortgage but significantly lower than credit cards or personal loans.

A Home Equity Line of Credit (HELOC) works more like a credit card. You are approved for a maximum credit limit and can draw and repay funds repeatedly during the draw period, usually ten years. You only pay interest on what you have drawn. After the draw period ends, the repayment period begins, typically twenty years, during which you repay both principal and interest. HELOC rates are variable, indexed to the prime rate, which means your payment can rise substantially if rates increase. HELOCs are better suited for ongoing or unpredictable expenses, home renovations over multiple years, or situations where you want available credit but may not use all of it.

Cash-Out Refinancing: When It Makes Sense

A cash-out refinance replaces your existing mortgage with a new, larger mortgage and gives you the difference in cash. If you owe $200,000 on your home and refinance into a $280,000 mortgage, you walk away with $80,000 in cash (minus closing costs, which typically run 2% to 5% of the loan amount). The advantage is that you have one payment instead of two, and if you refinance to a lower rate than your existing mortgage carries, you can potentially improve your overall financial picture while accessing equity.

The disadvantage in 2026 is that mortgage rates have been substantially higher than rates many homeowners locked in during 2020 and 2021. Refinancing a 3% mortgage into a 7% mortgage to access equity might not make financial sense even if it provides liquidity, because the long-term interest cost of the new loan can exceed the benefit of the cash. A home equity loan or HELOC on top of a low-rate first mortgage often makes more sense in this environment because you leave the existing mortgage untouched.

How Much Can You Borrow Against Your Home Equity

Lenders do not let you borrow the full amount of your equity. Most home equity lenders use a combined loan-to-value (CLTV) limit, typically 80% to 85%. If your home is worth $400,000 and the lender uses an 85% CLTV limit, the maximum combined debt secured by your property is $340,000. If you still owe $250,000 on your first mortgage, the maximum you can borrow through a home equity product is $90,000.

Beyond the CLTV limit, lenders evaluate your income, debt-to-income ratio, credit score, and payment history. A credit score below 680 will make most home equity borrowing significantly more expensive or unavailable at mainstream lenders. Lenders also look at your overall debt-to-income ratio, typically wanting your total debt payments including the new product to stay below 43% of gross income, though some lenders go higher for strong credit borrowers.

Smart Uses for Home Equity

Using equity to fund home improvements that increase property value is one of the most defensible uses because you are reinvesting in the asset that secures the loan. Kitchen remodels, bathroom updates, additions that add square footage, and energy efficiency upgrades generally produce reasonable return on investment. Roof replacement and HVAC upgrades do not increase value much but protect the asset and are reasonable maintenance expenses.

Consolidating high-interest debt can also make sense if you have the financial discipline to not run up the credit cards again. Replacing $25,000 in credit card debt at 22% with a home equity loan at 8% saves over $3,000 per year in interest and converts unsecured debt into secured debt, which carries its own risk but can be a net positive for someone with stable income and a concrete repayment plan. Using equity to fund education, cover a medical emergency, or bridge a genuine income gap can be appropriate in specific circumstances.

When Not to Tap Your Home Equity

Using home equity for discretionary spending, vacations, or depreciating assets is rarely a good idea because you are pledging your house against purchases that provide no lasting financial benefit. The core risk with any home equity borrowing is that if you cannot make payments, the lender can foreclose. Unlike credit card debt, which is unsecured, a default on a home equity loan can cost you your home.

People who are close to retirement should be particularly cautious about borrowing heavily against home equity, because any disruption to income in retirement could make payments difficult. If you are within five years of retirement and considering a significant home equity borrowing, model out what the payments look like on your projected retirement income before committing. Our retirement calculator can help you assess whether your retirement income supports the additional debt payment.

Tax Deductibility of Home Equity Interest in 2026

The Tax Cuts and Jobs Act of 2017 changed the deductibility rules for home equity interest. Interest on home equity debt is now only deductible if the loan proceeds were used to buy, build, or substantially improve the home that secures the loan. Using a HELOC for home improvements preserves deductibility. Using a HELOC to pay off credit cards or fund a vacation does not.

The total mortgage debt limit for deductible interest is $750,000 for loans taken after December 15, 2017 (the old limit of $1 million applies to debt taken before that date). If your total secured debt exceeds $750,000, only the interest on the first $750,000 is potentially deductible. Given that itemizing makes sense for fewer households after the TCJA standard deduction increase, many home equity borrowers no longer benefit from the interest deduction regardless. Consult a tax professional if the deductibility question affects your decision. For related tools, see our guide on how much house you can afford and our mortgage calculator.
