Complete Guide to Home Equity
What Is Home Equity?
Home equity is the portion of your property that you truly own — the difference between its current market value and the amount you still owe on your mortgage. As you pay down your loan and as property values rise, your equity grows.
Equity is a major component of household net worth and can be tapped through a home equity loan, HELOC, or cash-out refinance. Use our Mortgage Affordability Calculator to see how much home you can afford, or the Down Payment Calculator if you are still in the buying phase.
Key Formulas
Home Equity:
Equity = Current Home Value − Mortgage Balance
Equity % = (Equity ÷ Current Home Value) × 100
Where: Current Home Value = today's market value, Mortgage Balance = remaining principal owed
LTV & HELOC Limit:
LTV = (Mortgage Balance ÷ Home Value) × 100
HELOC Limit = (Home Value × Max CLTV%) − Mortgage Balance
Where: Max CLTV% is typically 80% (lender-dependent, some allow up to 90%)
Benefits of Knowing Your Equity
Refinancing Decisions
Knowing your LTV helps you qualify for better refinance rates and eliminate PMI when you cross the 80% equity threshold.
HELOC Access
A HELOC lets you borrow against your equity for renovations, debt consolidation, or emergencies at rates lower than credit cards.
Net Worth Tracking
Home equity is often the largest asset on a household balance sheet. Track it alongside your Net Worth Calculator results.
Sale Proceeds Estimate
When selling, equity minus closing costs (5–6%) approximates your cash proceeds. Essential for planning your next purchase.
Tips for Building Equity Faster
Make extra principal payments: Even an extra $100/month can shave years off your mortgage and save tens of thousands in interest. Use our Loan Amortization Calculator to see the impact.
Invest in home improvements: Kitchen and bathroom renovations typically recoup 60–80% of cost in added home value, boosting your equity beyond the improvement cost.
Avoid cash-out refinancing unless strategic: Pulling equity out resets your LTV higher and increases total interest paid. Only tap equity for investments with returns exceeding your mortgage rate.
Common Mistakes
Overestimating Home Value
Online estimates (Zestimate, Redfin, etc.) can be off by 5–15%. For major financial decisions like HELOCs or refinancing, get a professional appraisal — lenders will require one anyway.
Ignoring Second Liens
If you have an existing HELOC or second mortgage, those balances must be added to your primary mortgage when calculating true LTV and available equity.
Treating Equity as Liquid Cash
Equity is illiquid — accessing it requires borrowing (HELOC/loan) or selling. Factor in closing costs, appraisal fees, and time when planning to use equity.

OpenFrequently Asked Questions
What is home equity and how is it calculated?
Home equity is the difference between your property's current market value and the outstanding mortgage balance. Formula: Equity = Current Home Value − Mortgage Balance. For example, a home worth $400,000 with a $220,000 mortgage has $180,000 in equity (45% equity, 55% LTV).
What is Loan-to-Value (LTV) ratio and why does it matter?
LTV = Mortgage Balance ÷ Current Home Value × 100. Lenders use LTV to assess risk: below 80% LTV you avoid PMI, qualify for better refinance rates, and can access HELOCs. An LTV above 100% means you are 'underwater' — you owe more than the home is worth.
How much can I borrow with a HELOC?
Most lenders cap your combined loan-to-value (CLTV) at 80–85%. HELOC limit = (Home Value × Max CLTV%) − Mortgage Balance. On a $400,000 home with $220,000 owed and 80% CLTV cap, your max HELOC is $100,000. Some lenders allow 90% CLTV with higher rates.
How does this differ from the Down Payment Calculator?
The Down Payment Calculator helps pre-purchase buyers plan how much cash to put down and estimate PMI. This Home Equity Calculator is for current homeowners — it measures how much equity you have built, your HELOC borrowing power, and how long until you own free and clear.
What are common mistakes when estimating home equity?
Three frequent errors: (1) using the original purchase price instead of current market value — equity changes as the market moves; (2) forgetting to subtract the full mortgage balance including any second liens or HELOCs already outstanding; (3) assuming Zillow/Redfin estimates are exact — get a professional appraisal for major decisions like refinancing.
Can you show a worked example?
Home currently worth $400,000, purchased at $300,000, mortgage balance $220,000. Equity = $400,000 − $220,000 = $180,000 (45%). LTV = 55%. At 80% CLTV, HELOC limit = ($400,000 × 0.80) − $220,000 = $100,000. Appreciation = $100,000 (+33.3% from purchase price).
