How to Calculate Home Equity

Complete step-by-step guide to understanding and calculating your home's equity

The Simple Formula

Home Equity = Current Home Value - Outstanding Mortgage Balance

This basic formula gives you your total equity amount, but there's more to understand about how lenders calculate your available borrowing power.

Step-by-Step Calculation Process

1

Determine Your Home's Current Value

Your home's current market value is the foundation of equity calculation. This isn't the price you paid, but what your home would sell for in today's market.

Methods to determine value:

  • Professional appraisal: Most accurate, costs $400-800
  • Automated Valuation Models (AVMs): Zillow, Redfin estimates
  • Comparative Market Analysis (CMA): Real estate agent analysis
  • Recent sales data: Check similar homes in your area

Valuation Tips

Use multiple sources for best estimate
Consider recent improvements and upgrades
Account for local market conditions
Be conservative in your estimates

Where to Find Your Balance

Monthly mortgage statement
Online banking or lender portal
Annual loan statement
Call your mortgage servicer
Mobile banking app
2

Find Your Current Mortgage Balance

You need the current principal balance, not your original loan amount. This balance decreases each month as you make payments (assuming it's not an interest-only loan).

Important considerations:

  • Use the principal balance, not the payment amount
  • Include any second mortgages or HELOCs
  • Don't include escrow balances
  • Account for recent payments that may not be reflected
3

Calculate Your Total Equity

Subtract your total mortgage debt from your home's current value. This gives you your total equity position.

Example Calculation:

Current home value:$450,000
First mortgage balance:$280,000
HELOC balance:$15,000
Total Home Equity:$155,000

Equity vs. Available Borrowing

Your total equity and available borrowing are different. Lenders typically limit loans to 80-90% of home value, minus existing mortgages.

Home value ($450,000 × 85%):$382,500
Minus existing debt:$295,000
Available to borrow:$87,500

Factors That Affect Your Home Equity

Market Appreciation

Rising home values in your area increase your equity automatically, even without paying down the mortgage.

Mortgage Payments

Each payment reduces your loan balance, increasing equity. Early payments reduce principal faster.

Extra Principal Payments

Additional payments toward principal directly increase equity and reduce interest costs over time.

Home Improvements

Strategic renovations can increase home value, though not always dollar-for-dollar with the cost.

Market Decline

Falling home values reduce equity and can lead to negative equity if values drop significantly.

Additional Borrowing

Taking cash-out refinances, HELOCs, or second mortgages reduces available equity.

Understanding Loan-to-Value (LTV) Ratio

The Loan-to-Value (LTV) ratio is a critical metric lenders use to assess risk and determine borrowing limits. It's calculated by dividing your total mortgage debt by your home's current value.

LTV Calculation

LTV = (Total Mortgage Debt ÷ Home Value) × 100
$300,000
Total Debt
÷ $400,000
Home Value
= 75% LTV
Current Ratio

LTV Impact on Borrowing

≤ 60% LTV

  • • Best rates available
  • • Maximum borrowing potential
  • • Easiest approval process
  • • May waive some fees

60-80% LTV

  • • Standard rates
  • • Good borrowing options
  • • Normal approval process
  • • Standard fee structure

80-90% LTV

  • • Higher rates
  • • Limited borrowing
  • • Stricter requirements
  • • Additional fees possible

Combined LTV (CLTV)

When you have multiple mortgages (first mortgage + HELOC/second mortgage), lenders calculate the Combined Loan-to-Value (CLTV) ratio. This includes all debt secured by your home and typically can't exceed 90% for most home equity products.

Common Equity Calculation Mistakes

❌ Using Purchase Price Instead of Current Value

Mistake: Calculating equity based on what you paid for the home years ago.

Reality: Your home's current market value may be significantly higher (or lower) than your purchase price.

❌ Forgetting About Second Mortgages

Mistake: Only subtracting the first mortgage balance.

Reality: All mortgages, HELOCs, and liens against the property reduce available equity.

❌ Overestimating Home Value

Mistake: Using optimistic online estimates or wishful thinking.

Reality: Lenders use conservative appraisals that may be lower than online estimates.

❌ Confusing Equity with Borrowing Power

Mistake: Thinking you can borrow your full equity amount.

Reality: Lenders typically limit borrowing to 80-90% of home value, minus existing debt.

❌ Not Accounting for Closing Costs

Mistake: Expecting to receive the full loan amount in cash.

Reality: Closing costs (2-5% of loan amount) reduce the cash you actually receive.

What to Do After Calculating Your Equity

If You Have Substantial Equity (20%+)

  • Consider your borrowing options (HELOC vs Home Equity Loan)
  • Shop rates from multiple lenders
  • Get pre-qualified to understand terms
  • Plan your intended use of funds

If You Have Limited Equity (<20%)

  • Focus on building equity through payments
  • Consider home improvements that add value
  • Wait for market appreciation
  • Explore alternative financing options
