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."

Maximize Your Borrowing Power with Our Line of Credit Calculator
Learn how to calculate your available home equity line of credit (HELOC), understand LTV ratios, and make informed borrowing decisions
A Home Equity Line of Credit (HELOC) can be a powerful financial tool, allowing homeowners to access their home's equity for major expenses, debt consolidation, or investments. However, understanding how much you can actually borrow requires careful calculation of your home equity and loan-to-value ratio.
In this comprehensive guide, we'll explore how our Line of Credit Calculator can help you determine your borrowing capacity, visualize your equity breakdown, and make informed decisions about leveraging your home's value.
Why Home Equity Matters for Borrowing
What is Home Equity?
Home equity is the portion of your home that you truly own—the difference between your home's current market value and the outstanding balance of all liens (like your mortgage). It represents your financial stake in your property and can be used as collateral for loans.
Understanding your home equity helps you:
- Access borrowing power: Use your equity to secure favorable loan terms
- Plan major expenses: Fund home improvements, education, or other large costs
- Consolidate debt: Potentially lower interest rates by using home equity
- Build wealth: Track your growing ownership in your property
- Make financial decisions: Understand when it makes sense to tap into equity

Understanding Loan-to-Value (LTV) Ratio
The LTV ratio is a critical factor that lenders use to determine your borrowing capacity:
Standard HELOC LTV
Most lenders allow 80-85% LTV for home equity lines of credit, meaning your total borrowing (mortgage + HELOC) can't exceed 80-85% of your home's value.
Cash-Out Refinance LTV
For cash-out refinances, lenders may allow up to 80-90% LTV, depending on your credit score and other factors.
First-Time Homebuyer LTV
Some programs allow first-time homebuyers to purchase with as little as 3% down, resulting in a 97% LTV ratio.

Pro Tip: Maximize Your Borrowing Power
If you've made significant home improvements or your local market has appreciated, consider getting a new appraisal. A higher home value can substantially increase your available equity and borrowing capacity.
Understanding Key HELOC Metrics
Home Equity Calculation
Your home equity is the foundation of your borrowing power:
| Component | Calculation | Importance |
|---|---|---|
| Home Value | Current market appraisal | Determines maximum potential equity |
| Mortgage Balance | Remaining loan principal | Represents existing claim on your property |
| Home Equity | Home Value - Mortgage Balance | Your ownership stake in the property |
Available Credit Line Calculation
Lenders determine your available credit based on several factors:
- Maximum LTV: Typically 80-85% of home value for HELOCs
- Credit score: Higher scores may qualify for better terms
- Debt-to-income ratio: Your ability to make payments
- Property type: Primary residences typically have better terms
Interest-Only vs. Amortizing Payments
HELOCs typically have two phases:
- Draw period (5-10 years): Make interest-only payments
- Repayment period (10-20 years): Make principal + interest payments
Common HELOC Pitfalls
Avoid these common mistakes when considering a home equity line of credit:
- Over-borrowing: Don't max out your credit line without a clear repayment plan
- Variable rates: Understand that HELOC rates can increase over time
- Misusing funds: Avoid using home equity for discretionary spending
- Ignoring fees: Account for closing costs, annual fees, and other charges
- Underestimating risk: Remember your home is collateral - default could mean foreclosure

Frequently Asked Questions
What's the difference between a HELOC and a home equity loan?
A HELOC is a revolving line of credit (like a credit card) that you can draw from as needed, while a home equity loan provides a lump sum upfront with fixed payments. HELOCs typically have variable rates, while home equity loans often have fixed rates.
How does my credit score affect my HELOC eligibility?
Lenders typically require a credit score of 680 or higher for a HELOC, with better terms available for scores above 720. Your credit score affects both your eligibility and the interest rate you'll receive.
Can I get a HELOC with less than 20% equity?
Most lenders require at least 15-20% equity in your home (80-85% LTV ratio). If you have less equity, you may need to explore other borrowing options or wait until you've built more equity.
Are there tax benefits to a HELOC?
Under current tax law, you can deduct interest on a HELOC if the funds are used to "buy, build, or substantially improve" your home. Interest on funds used for other purposes is generally not deductible.
What happens if my home value decreases after I get a HELOC?
If your home value decreases significantly, your lender may reduce your credit limit or freeze further draws. However, you're still responsible for repaying any amounts you've already borrowed.
