Calculate your home equity, loan-to-value ratio, and borrowable equity based on current home value and mortgage balance.

Home equity is the difference between your home's current market value and the outstanding balance on your mortgage. If your home is worth $400,000 and you owe $250,000, you have $150,000 in equity — 37.5% of your home's value. Home equity is the single largest component of net worth for most American households, representing over 60% of median household wealth.1
Equity builds in two ways: paying down your mortgage principal and home price appreciation. In the early years of a mortgage, most of each payment goes to interest, so equity builds slowly. As the loan matures, more goes to principal, accelerating equity accumulation. Meanwhile, home prices have historically appreciated 3–5% annually nationwide, though local markets vary dramatically. Coastal cities and high-demand metros have seen much higher appreciation, while some rural areas and post-industrial towns have experienced flat or declining values over extended periods.
Understanding the distinction between these two equity sources matters for financial planning. Principal paydown is predictable and entirely within your control — it happens automatically with every mortgage payment, and you can accelerate it with extra payments. Appreciation, by contrast, is market-driven and uncertain. Building a financial plan that relies heavily on appreciation is risky; treating it as a bonus above your principal paydown provides a more conservative and reliable foundation.
The calculation is straightforward: Home Equity = Current Market Value − Remaining Mortgage Balance. Your equity percentage is (Equity ÷ Market Value) × 100. This percentage matters because lenders use it to determine loan-to-value (LTV) ratios for refinancing, HELOCs, and PMI removal.2
For example, if you purchased a home for $350,000 with a $280,000 mortgage (20% down) and the home has since appreciated to $410,000 while you have paid the balance down to $260,000, your equity is $150,000 (36.6%). This is a dramatic improvement from the $70,000 (20%) equity at purchase — driven by both $20,000 in principal payments and $60,000 in appreciation.
| Year | Remaining Balance (6.5%, $350K loan) | Home Value (3% appreciation, $400K start) | Equity | Equity % |
|---|---|---|---|---|
| 0 (Purchase) | $350,000 | $400,000 | $50,000 | 12.5% |
| 5 | $327,000 | $464,000 | $137,000 | 29.5% |
| 10 | $296,000 | $537,000 | $241,000 | 44.9% |
| 15 | $254,000 | $623,000 | $369,000 | 59.2% |
| 20 | $198,000 | $722,000 | $524,000 | 72.6% |
| 30 | $0 | $971,000 | $971,000 | 100% |
Approximate values. Actual results depend on interest rate, payment schedule, and local appreciation rates.
Once you have built substantial equity, you can access it through several financial products:
Home Equity Loan (HEL): A fixed-rate, lump-sum second mortgage repaid over 5–30 years. Best for one-time expenses with a known cost (renovation, debt consolidation). Rates are typically 1–2% above first mortgage rates.3
Home Equity Line of Credit (HELOC): A revolving credit line secured by your home, with a variable rate. Draw what you need during the draw period (usually 10 years), then repay over 10–20 years. Best for ongoing expenses or uncertain costs. See our HELOC Calculator for details.
Cash-Out Refinance: Replace your existing mortgage with a larger one and pocket the difference. Makes sense when current rates are lower than your existing rate, or when you need a large sum and want to consolidate into a single payment. Compare options with our HELOC vs Cash-Out Refi Calculator.
Reverse Mortgage (62+): For homeowners 62 and older, a reverse mortgage converts equity into income without monthly payments. The loan is repaid when the homeowner sells, moves, or passes away. The most common type, the Home Equity Conversion Mortgage (HECM), is insured by the FHA and allows borrowers to receive funds as a lump sum, monthly payments, or a line of credit. Borrowers must continue paying property taxes, insurance, and maintenance to avoid default.
| Product | Typical Rate | Type | Best For |
|---|---|---|---|
| Home Equity Loan | 7.5–9.5% | Fixed, lump sum | Known one-time expense |
| HELOC | 7.0–9.0% | Variable, revolving | Flexible ongoing access |
| Cash-Out Refi | 6.5–8.0% | Fixed, new first mortgage | Large sum + rate improvement |
| Reverse Mortgage | Variable/Fixed | No payments until sale | Retirement income (62+) |
Private Mortgage Insurance (PMI) is required on conventional loans when your equity is below 20%. PMI typically costs 0.5–1.5% of the loan amount annually — on a $300,000 loan, that is $1,500–$4,500/year ($125–$375/month). Once you reach 20% equity, you can request PMI removal from your lender. At 22% equity, the lender is legally required to remove it automatically under the Homeowners Protection Act.4
Reaching the 20% threshold faster saves significant money. Extra principal payments, home improvements that increase appraised value, and natural market appreciation all contribute. If your home has appreciated significantly since purchase, you may be able to request a new appraisal to prove you have crossed the 20% line earlier than scheduled.
Make extra principal payments: Even $100/month extra on a $300,000, 30-year, 6.5% mortgage saves $59,000 in interest and shaves 5 years off the loan.
Bi-weekly payments: Paying half your monthly payment every two weeks results in 26 half-payments (13 full payments) per year instead of 12, cutting years off a 30-year mortgage.
Strategic improvements: Kitchen and bathroom remodels, energy efficiency upgrades, and curb appeal improvements can increase home value. However, not all renovations return their cost — a $50,000 kitchen remodel may only add $35,000–$40,000 in appraised value.
Avoid cash-out refinancing unless necessary: Every dollar of equity you borrow against resets your position and adds interest costs. Use home equity strategically, not as an ATM.
Choose a shorter loan term: A 15-year mortgage builds equity roughly twice as fast as a 30-year loan because a much larger share of each payment goes to principal from day one. On a $300,000 loan at 6%, the monthly payment is about $2,532 on a 15-year term versus $1,799 on a 30-year — but after five years, the 15-year borrower has paid down $113,000 in principal compared to just $24,000 on the 30-year. If you can afford the higher payment, the accelerated equity growth and interest savings are substantial.
Certain equity thresholds are financially meaningful because they unlock specific benefits or eliminate costs. Understanding these milestones helps you set concrete goals for your equity-building strategy.
| Equity % | Milestone | What It Means |
|---|---|---|
| 10% | Minimum for most HELOCs | Some lenders offer home equity credit lines once you pass 10% equity, though rates will be higher and limits lower than at higher equity levels. |
| 20% | PMI removal eligible | You can formally request PMI cancellation from your servicer. On a $350,000 loan, removing PMI saves $1,750–$5,250/year depending on your credit score and original down payment. |
| 22% | Automatic PMI cancellation | Lenders must cancel PMI by law once your loan balance reaches 78% of the original purchase price, based on the original amortization schedule. |
| 30–40% | Best HELOC/HEL rates | With a combined loan-to-value (CLTV) under 70%, you qualify for the most competitive home equity borrowing rates and highest credit limits. |
| 50%+ | Strong financial cushion | At 50%+ equity, you are well-protected against market downturns. Even a 20% decline in home values would leave you with positive equity. |
| 100% | Free and clear | No mortgage payment. Your home is fully yours, and the entire market value represents your wealth. Monthly housing costs drop to just taxes, insurance, and maintenance. |
Overestimating your home's value: Online estimates from Zillow, Redfin, and Realtor.com can vary by 5–15% from actual market value. For important financial decisions — PMI removal, HELOC applications, refinancing — get a professional appraisal ($300–$600) rather than relying on algorithmic estimates.
Treating equity as spending money: Home equity is a long-term wealth-building asset, not a checking account. Repeatedly tapping equity for consumer spending (vacations, cars, lifestyle inflation) erodes your financial foundation and adds years of interest payments. Reserve equity borrowing for investments that build value: home improvements, education, or debt consolidation at lower rates.
Ignoring market risk: Home values can decline, sometimes sharply. Homeowners who borrowed heavily against equity in 2005–2006 found themselves underwater by 2008–2010. Keeping at least 20% equity as a buffer protects against negative equity scenarios and preserves your financial flexibility.
Forgetting closing costs: Accessing equity through a HELOC, home equity loan, or cash-out refinance involves closing costs typically ranging from 2–5% of the amount borrowed. On a $100,000 cash-out refinance, that is $2,000–$5,000 in fees — a meaningful reduction in net proceeds that should factor into your break-even analysis.
→ Track equity annually. Review your home's value (comps, Zestimate) and mortgage balance each year. Crossing the 20% threshold triggers PMI removal — do not let it continue paying unnecessarily.
→ Do not over-borrow. Lenders may let you borrow up to 85% of equity, but doing so leaves you vulnerable if home values decline. Keep at least 20% equity as a buffer.
→ Consider tax implications. Interest on home equity borrowing is tax-deductible only if the funds are used to buy, build, or substantially improve the home securing the loan (post-2017 TCJA rules).
→ Factor in closing costs. Accessing equity through any product involves closing costs (1–5% of the amount), which reduces the net proceeds and should be factored into your decision.
