HELOC Calculator: Complete Guide
A Home Equity Line of Credit (HELOC) can be a powerful financial tool for homeowners looking to access their home's equity for major expenses, home improvements, or debt consolidation. Understanding how HELOCs work and calculating your potential borrowing power is essential for making informed financial decisions.
What Is a HELOC?
HELOC Definition
Home Equity Line of Credit (HELOC) is a revolving line of credit that allows homeowners to borrow against the equity in their home. Unlike a traditional loan with a fixed amount, a HELOC works more like a credit card with a set credit limit that you can draw from as needed.
HELOCs typically have two distinct phases:
- Draw Period: Usually 5-10 years where you can borrow funds and make interest-only payments
- Repayment Period: Typically 10-20 years where you must repay both principal and interest

The HELOC Calculation Formula
Available Equity Formula
Available Equity = Home Value - Mortgage Balance
Example: $500,000 - $300,000 = $200,000
LTV Calculation Formula
LTV Ratio = (Mortgage Balance + HELOC Amount) ÷ Home Value × 100
Example: ($300,000 + $100,000) ÷ $500,000 × 100 = 80%
Variable Definitions
- Home Value: Current market value of your home.
- Mortgage Balance: Remaining balance on your primary mortgage.
- Credit Limit: Maximum LTV ratio allowed by lender (typically 80-90%).
- Interest Rate: Annual percentage rate on your HELOC (usually variable).
- Draw Period: Years you can borrow (interest-only payments).
- Repayment Period: Years to repay principal + interest after draw period.

Frequently Asked Questions
What's the difference between a HELOC and a home equity loan?
A HELOC is a revolving line of credit while a home equity loan provides a lump sum with fixed payments. HELOCs offer flexibility but have variable rates.
How much can I borrow with a HELOC?
Most lenders allow up to 80-90% of your home's value minus your mortgage balance. Our calculator helps determine your specific limit.
Are HELOC interest payments tax-deductible?
HELOC interest may be deductible if funds are used to "buy, build, or substantially improve" your home. Consult a tax professional.
Can I lose my home if I can't make HELOC payments?
Yes, since your home secures the HELOC, the lender can foreclose if you default. Only borrow what you can comfortably repay.
What happens if my home value decreases?
Your lender may reduce your credit limit or freeze your ability to draw funds, even if you haven't reached your original limit.
