Home Equity Calculator | Value Minus Mortgage Owed

The Home Equity Calculator shows how much of your home you actually own, free and clear of debt. Enter your home’s current estimated value and what you still owe across any mortgages or liens, and see your equity amount, your loan-to-value (LTV) ratio, and roughly how much you could borrow against your home at a typical lending limit.

Home Equity Estimator

Use a recent appraisal, a comparative market estimate, or an online valuation as your home value. Include every loan secured against the property in the balance owed.

Home Equity

Home Equity = Current Home Value − Total Debt Owed

Total debt owed is the sum of your first mortgage and any additional loans secured against the property, such as a second mortgage or HELOC.

Loan-to-Value (LTV) Ratio

LTV (%) = (Total Debt Owed ÷ Current Home Value) × 100

LTV is the inverse view of equity — a lower LTV means more equity and typically better refinancing or borrowing terms.

Equity Percentage

Equity (%) = 100% − LTV (%)

Estimated Borrowable Equity

Borrowable Equity = (Target LTV % × Home Value) − Total Debt Owed

Lenders typically cap total borrowing (across all liens combined) at a maximum combined loan-to-value — often around 80% — rather than lending against 100% of your equity.

💡 Note: If total debt exceeds your home’s value, equity is negative — this is sometimes called being “underwater” or “upside down” on a mortgage.

Common Uses for This Calculator

  • HELOC or home equity loan applications: Estimate how much you might qualify to borrow
  • Refinancing: Check whether your LTV qualifies for better refinance rates
  • Selling your home: Estimate proceeds after paying off remaining mortgage balances
  • Net worth tracking: Include home equity as part of your overall net worth
  • Removing PMI: Many lenders drop private mortgage insurance once LTV falls to 80% or below

Worked Example

Scenario: Your home is worth 350,000. You owe 210,000 on your first mortgage and 15,000 on a HELOC. Your lender’s maximum combined LTV for new borrowing is 80%.

Total debt = 210,000 + 15,000 = 225,000
Home equity = 350,000 − 225,000 = 125,000
Current LTV = 225,000 ÷ 350,000 = 64.3%
Max loan at 80% LTV = 350,000 × 80% = 280,000
Additional borrowable equity = 280,000 − 225,000 = 55,000
⚠️ Important: This is an estimate based on the home value you enter. Lenders will typically require their own appraisal, and actual borrowing limits depend on credit score, income, debt-to-income ratio, and lender policy — not equity alone.

Frequently Asked Questions

How do I estimate my home’s current value?

Common sources include a recent professional appraisal, a comparative market analysis from a real estate agent, or an automated valuation model from a listing site — each carries different accuracy, so treat online estimates as a starting point rather than a guarantee.

What counts as debt owed against the home?

Include your first mortgage balance plus any second mortgage, home equity loan, or HELOC balance secured against the same property. Unsecured debt like credit cards is not part of this calculation.

Why is the target LTV usually around 80%?

Many lenders cap combined loan-to-value at 80% for home equity products, keeping a cushion in case home values decline, though some lenders allow higher limits for well-qualified borrowers.

What does negative equity mean?

If your total debt owed is greater than your home’s current value, your equity is negative — you would owe more than the home is worth if sold today.

Does paying down my mortgage increase equity right away?

Yes, every principal payment reduces your debt owed and increases equity directly, separate from any change in the home’s market value.

Tips

Before Relying on This Result:
  • Use a realistic, current value: not the original purchase price
  • Include every lien: forgetting a second mortgage overstates your equity
  • Confirm with your lender: actual borrowing limits depend on more than equity alone
Quick summary: Enter your home’s current value and what you owe across all mortgages and liens to see your equity, current loan-to-value ratio, and roughly how much additional equity you could borrow at a typical lending limit.

Understanding Home Equity

Home equity is the portion of your home you truly own — the difference between what it’s worth today and what you still owe against it. Every mortgage payment that reduces principal builds equity, and so does any rise in your home’s market value. Together, these two forces mean equity typically grows over time, even without extra payments, as long as home values hold steady or increase.

Lenders view equity through the loan-to-value ratio, comparing total debt to home value rather than looking at equity in isolation. A lower LTV signals lower risk to a lender, which is why it affects refinance rates, mortgage insurance requirements, and how much additional financing — like a HELOC or home equity loan — you may be able to secure against the property.

Who Uses This Calculator

Homeowners considering a HELOC or home equity loan, those exploring refinancing, sellers estimating proceeds, and anyone tracking net worth can use this tool to see their current equity position. It is for estimation and planning; always confirm your home’s value and borrowing limits with a lender or licensed appraiser before making financial decisions.
