Home Equity Calculator
Estimate your total home equity, equity percentage, and how much you may be able to borrow based on your target loan-to-value (LTV).
What is home equity?
Home equity is the portion of your property you truly own. In simple terms, it is your home’s market value minus everything you still owe on it. If your home is worth $500,000 and your total mortgage debt is $320,000, you have $180,000 in equity.
As your home value rises and your loan balances drop, your equity grows. This is why many homeowners treat equity as a long-term wealth-building tool.
How this calculator works
This home equity calculator uses five inputs to provide practical numbers you can use for planning:
- Current home value (your best estimate or appraisal-based value)
- Primary mortgage balance (remaining principal on your first mortgage)
- Second lien balance (HELOC or second mortgage, if any)
- Target max CLTV (combined loan-to-value, often 80% to 90%)
- Selling cost estimate (commissions, transfer taxes, and closing costs)
Key formulas used
- Total Equity = Home Value − (Primary Mortgage + Second Lien)
- Equity % = Total Equity ÷ Home Value × 100
- Estimated Borrowing Capacity = (Home Value × Max CLTV) − Total Current Debt
- Estimated Net Proceeds if Sold = Home Value − Selling Costs − Total Debt
If borrowing capacity is negative, the calculator shows $0 available to borrow, which means your debt already meets or exceeds the chosen CLTV threshold.
How homeowners typically use equity
1) Home improvements
Renovations can increase both enjoyment and resale value. Projects like kitchens, baths, roofing, HVAC upgrades, and energy improvements are common uses of home equity funds.
2) Debt consolidation
Some homeowners refinance higher-interest debt into a lower-rate secured loan. This can reduce monthly payments, but it also puts your home at risk if payments are missed.
3) Education or major life expenses
Equity can be used strategically for tuition, family support, or one-time expenses, especially when compared with higher-cost borrowing options.
4) Emergency liquidity planning
A HELOC can function as a backup source of funds. Even if unused, access to credit can be valuable in uncertain periods.
What affects your home equity over time?
- Local property market trends: appreciation increases equity, depreciation reduces it.
- Loan repayment pace: extra principal payments grow equity faster.
- Refinancing choices: cash-out refinancing can reduce equity.
- New liens: additional borrowing lowers available equity.
- Maintenance quality: deferred repairs can hurt appraised value.
Example
Suppose your home is worth $600,000, your first mortgage is $350,000, and your HELOC balance is $20,000. Your equity is:
$600,000 − ($350,000 + $20,000) = $230,000
Your equity percentage is about 38.3%. If your lender allows up to 80% CLTV, total debt could be as high as $480,000. Since you currently owe $370,000, estimated additional borrowing room is about $110,000 (before lender fees and underwriting constraints).
Best practices before borrowing against equity
- Compare a home equity loan, HELOC, and cash-out refinance side by side.
- Check whether rates are fixed or variable, and model payment increases.
- Keep CLTV conservative to reduce risk during market downturns.
- Avoid using secured debt for recurring lifestyle spending.
- Review payoff timelines and total interest cost—not just monthly payment.
Frequently asked questions
Is 20% equity important?
Yes. In many cases, reaching at least 20% equity can help remove private mortgage insurance (PMI) and improve refinancing options.
What is the difference between LTV and CLTV?
LTV compares your primary mortgage to home value. CLTV includes all liens (first mortgage + HELOC + second mortgage), which is what many lenders use for home equity approval.
Can I borrow all of my equity?
Usually no. Most lenders impose a maximum CLTV limit, often around 80% to 90%, though this varies by lender and borrower profile.
Is this calculator a loan approval tool?
No. It is a planning calculator designed to provide quick estimates. Final eligibility depends on credit score, income documentation, debt-to-income ratio, appraisal, and lender policies.
