Things to Know
Essential concepts for understanding your results
How It WorksHow does home equity build over time?
Home equity = Current market value − Mortgage balance. Equity grows two ways: principal payments (each mortgage payment reduces the balance) and appreciation (home value increases). On a $350,000 home with $280,000 mortgage: equity = $70,000. After 5 years with 3% annual appreciation and regular payments: value ~$406,000, balance ~$260,000, equity ~$146,000. Early years, appreciation drives most equity growth because amortization is front-loaded with interest.
HELOC vs LoanWhat is the difference between a HELOC and home equity loan?
A home equity loan is a lump sum at a fixed rate — predictable payments like a second mortgage. A HELOC is a revolving credit line at a variable rate — draw money as needed during the draw period (typically 10 years), then repay over 10-20 years. HELOCs offer flexibility but rate risk. Home equity loans offer predictability but you pay interest on the full amount from day one.
LTV RatioWhat is loan-to-value ratio and why does it matter?
LTV = Total mortgage balance ÷ Home value × 100. At $280,000 owed on a $350,000 home: LTV = 80%. Most home equity lenders allow borrowing up to 80-85% combined LTV. With 80% max: ($350,000 × 0.80) − $280,000 = $0 available. With 85% max: ($350,000 × 0.85) − $280,000 = $17,500 available. Higher home values and lower mortgage balances unlock more borrowable equity.
Tax DeductibilityIs home equity loan interest tax-deductible?
Interest is deductible only if the loan is used to buy, build, or substantially improve the home securing the loan. Using a HELOC for a kitchen renovation: deductible. Using it for debt consolidation or a vacation: not deductible. The combined mortgage interest deduction is capped at $750,000 of total mortgage debt (first mortgage plus home equity). You must itemize deductions to claim — about 12% of taxpayers itemize.

Home equity is the difference between your home's current market value and what you owe on it — it is the portion of your home you actually "own." Home equity is the largest source of wealth for most American families: the Federal Reserve reports that total US homeowner equity reached $35.1 trillion in 2024, with the median homeowner having approximately $315,000 in equity.

How Home Equity Builds Over Time
| Year | Home Value (3% apprec.) | Mortgage Balance | Equity | Equity % |
|---|---|---|---|---|
| Purchase | $400,000 | $320,000 (20% down) | $80,000 | 20% |
| Year 3 | $437,000 | $304,000 | $133,000 | 30% |
| Year 5 | $464,000 | $293,000 | $171,000 | 37% |
| Year 10 | $538,000 | $260,000 | $278,000 | 52% |
| Year 15 | $623,000 | $218,000 | $405,000 | 65% |
| Year 20 | $722,000 | $163,000 | $559,000 | 77% |
| Year 30 | $970,000 | $0 | $970,000 | 100% |
Equity builds from two sources: (1) mortgage paydown — each payment reduces the balance, and (2) home appreciation — the property's value grows over time. In the early years, appreciation drives most equity growth (mortgage payments are mostly interest). In later years, accelerating principal paydown becomes the larger contributor.
Accessing Your Home Equity
HELOC (Home Equity Line of Credit): Variable rate (~8-9.5%), revolving credit, draw as needed. Best for ongoing expenses or emergency access. See our HELOC Calculator.
Home equity loan: Fixed rate (~8-10%), lump sum, fixed payments. Best for one-time expenses with known cost.
Cash-out refinance: Replace your mortgage with a larger one, taking the difference in cash. Best when refinance rate is lower than current mortgage rate.
How much can you access? Lenders allow a combined LTV (mortgage + equity borrowing) of 80-90%. With $278,000 equity on a $538,000 home: 85% CLTV allows $457,000 total debt. Minus $260,000 existing mortgage = $197,000 accessible. Tax deduction applies only if funds are used to buy, build, or improve the home (TCJA 2017).

How to Use This Calculator
Enter your home's current estimated value and your remaining mortgage balance. The calculator shows your available equity, loan-to-value ratio, and how much you could potentially borrow through a HELOC or home equity loan. Most lenders allow borrowing up to 80-85% of your home's value minus your existing mortgage balance.
Example: Home worth $450,000 with $280,000 remaining on the mortgage. Equity: $170,000 (37.8% LTV). At 80% combined LTV, you could borrow up to $80,000 ($450K × 80% = $360K - $280K = $80K). At 85% CLTV, you could borrow up to $102,500.
HELOC vs Home Equity Loan: Which Is Better?
| Feature | HELOC | Home equity loan |
|---|---|---|
| Interest rate | Variable (prime + margin) | Fixed |
| How you receive funds | Draw as needed (like a credit card) | Lump sum at closing |
| Payment structure | Interest-only during draw period, then P&I | Fixed monthly P&I from day 1 |
| Typical term | 10yr draw + 20yr repayment | 5-30 years fixed |
| Best for | Ongoing expenses (renovations, college) | One-time need (debt consolidation, major project) |
How Home Equity Builds Over Time
Equity grows from two sources: mortgage principal payments and home price appreciation. In the early years of a mortgage, most of your payment goes to interest, so equity builds slowly. After year 10-15, the amortization schedule shifts and principal payments accelerate.
| Year | Balance paid down | Home appreciation (3.5%) | Total equity ($400K home, $360K loan) |
|---|---|---|---|
| Year 1 | $5,800 | $14,000 | $59,800 (14%) |
| Year 5 | $33,400 | $75,600 | $149,000 (31%) |
| Year 10 | $77,800 | $166,000 | $283,800 (50%) |
| Year 15 | $136,200 | $276,400 | $452,600 (67%) |
Smart Uses for Home Equity (and Dangerous Ones)
Smart uses: Home renovations that increase value (kitchen, bathrooms — 60-80% ROI), consolidating high-interest credit card debt (replacing 22% cards with a 7-9% HELOC), or funding a child's education (tax-deductible interest if used for home improvement).
Dangerous uses: Funding a vacation, buying a car (use an auto loan instead — it is not secured by your home), investing in the stock market (leveraging your home for speculation), or covering ongoing living expenses (a sign of deeper financial problems). The fundamental risk: your home is the collateral. If you cannot repay, you can lose the house.
