A Home Equity Line of Credit (HELOC) is a revolving credit line that uses your home's equity as collateral. You can borrow up to your credit limit during the "draw period" (typically 10 years), then repay during the "repayment period."
Note: This calculator provides estimates only. Actual credit limits and terms depend on your credit score, income, and lender policies.

Understanding your home equity can unlock financial opportunities for renovations, debt consolidation, or emergencies. Our calculator makes it simple!
What is a Home Equity Line of Credit (HELOC)?
A Home Equity Line of Credit (HELOC) is like a credit card secured by your home's equity. It allows you to borrow money as you need it, up to a certain limit, using your home's value as collateral. Unlike a traditional loan where you get all the money at once, a HELOC gives you flexibility to borrow what you need when you need it.

Understanding Each Calculator Field
1. Your Home's Appraised Value
What it means: This is your home's current market value - what it would likely sell for today.
Example: If your home was appraised at $500,000, this is what you would enter.
Where to find it: Check recent comparable sales in your area, or use online tools like Zillow's Zestimate.
2. Mortgage(s) You Owe
What it means: The total amount you still owe on your mortgage(s). If you have a second mortgage or home equity loan, include those amounts too.
Example: If you started with a $400,000 mortgage and have paid down $100,000, you would enter $300,000.
Where to find it: Check your latest mortgage statement or online banking portal.
3. Loan-to-Value (LTV) Ratio
What it means: The percentage of your home's value that lenders are willing to lend you. Most lenders allow 80-85% LTV for HELOCs.
Example: An 80% LTV means the lender will lend up to 80% of your home's value.
Slider control: Use the slider to see how different LTV ratios affect your available credit line.
The Formula Behind the Calculator
How Your Credit Line is Calculated
Step 1: Calculate Your Current Equity
Example: $500,000 (Home Value) - $300,000 (Mortgage) = $200,000 (Equity)
Step 2: Calculate Your Current LTV Ratio
Example: ($300,000 ÷ $500,000) × 100 = 60% LTV
Step 3: Calculate Maximum Loan Amount
Example: ($500,000 × 80%) - $300,000 = $400,000 - $300,000 = $100,000
Step 4: Available Credit Line
Example: If Max Loan is positive, that's your available credit. If negative, you get $0.
Real-World Example
Let's follow Sarah's situation:
- Home Value: $500,000
- Mortgage Balance: $300,000
- LTV Ratio (set by lender): 80%
Step 1: $500,000 - $300,000 = $200,000 home equity
Step 2: ($300,000 ÷ $500,000) × 100 = 60% current LTV
Step 3: ($500,000 × 80%) - $300,000 = $400,000 - $300,000 = $100,000
Result: Sarah could qualify for up to $100,000 in credit line!
What the Pie Chart Shows You
The visual pie chart in the calculator breaks down your home's value into three easy-to-understand sections:
Blue Section: Mortgage Balance
This shows what percentage of your home's value is still mortgaged. The larger this section, the less equity you have available.
Green Section: Available Equity
This represents the equity you have in your home that you're NOT using for your HELOC. This is your financial cushion.
Gray Section: Potential Credit Line
This shows how much credit line you could access based on the LTV ratio you selected with the slider.

Frequently Asked Questions
Most lenders prefer LTV ratios between 80-85%. Some may go up to 90% for borrowers with excellent credit. The lower your LTV, the better terms you'll typically qualify for.
Yes, the same principles apply. However, lenders often have stricter LTV requirements for investment properties, typically 70-75% instead of 80-85%.
Add both mortgage balances together in the "Mortgage(s) You Owe" field. The calculator will consider your total mortgage debt against your home's value.
It provides accurate estimates based on standard lending formulas. However, actual approval amounts depend on your credit score, income, debt-to-income ratio, and specific lender policies.
This calculator doesn't include closing costs, appraisal fees, or annual fees that some HELOCs charge. It focuses on the principal amount you might qualify for.
Yes, the same calculation applies. For cash-out refinancing, you're essentially getting a new mortgage for more than you owe and taking the difference in cash.
Your credit score affects the interest rate you'll pay and possibly the maximum LTV ratio a lender will approve. Higher scores typically get better terms.
A HELOC is a revolving credit line (like a credit card), while a home equity loan gives you a lump sum upfront with fixed payments. Both use your home equity as collateral.
Most HELOCs have a 10-year draw period (when you can borrow) followed by a 20-year repayment period. Terms vary by lender.
Most HELOCs have variable interest rates tied to the prime rate. Some lenders offer fixed-rate options for portions of the balance.
Yes, most HELOCs allow early repayment without penalties. This can save you significant interest costs.
Lenders can freeze or reduce your credit line if your home value drops significantly. This is called a "HELOC freeze."
HELOC interest may be tax deductible if the funds are used to "buy, build, or substantially improve" the home securing the loan. Consult a tax professional.
Recalculate whenever your home value changes significantly, you make large mortgage payments, or you're considering using your equity.
When you sell your home, the HELOC balance must be paid off from the sale proceeds, just like your primary mortgage.
Next Steps After Calculating
- Check Your Credit Report: Make sure there are no errors that could affect your approval
- Shop Around: Different lenders offer different rates and terms for HELOCs
- Consider the Costs: Factor in appraisal fees, closing costs, and annual fees
- Plan Your Use: Have a clear purpose for the funds to avoid unnecessary debt
- Consult a Professional: Talk to a financial advisor about whether a HELOC makes sense for your situation
Smart Ways to Use Your HELOC
- Home Improvements: Increase your home's value (often tax-deductible)
- Debt Consolidation: Pay off high-interest credit cards
- Education Expenses: Fund college or career training
- Emergency Fund: Have a backup for unexpected expenses
- Investment Opportunities: Fund business ventures or investments
Remember: Only borrow what you need and can repay. Your home is the collateral!
