How to Calculate HELOC: Complete Guide
A Home Equity Line of Credit (HELOC) is a revolving credit line secured by your home equity. It's calculated by determining the maximum loan-to-value ratio allowed by the lender (typically 80-85%), then subtracting your current mortgage balance from that maximum to find your available credit line.
Quick Answer
To calculate HELOC amount: (Home Value × LTV Ratio) - Current Mortgage = Available HELOC. For example, a $400,000 home with 80% LTV and $200,000 mortgage balance equals $120,000 available HELOC.
HELOC Calculation Formula
The fundamental calculation determines your maximum borrowing capacity based on home equity.
Step-by-Step Process:
- 1Determine Home Value: Get a current market value estimate through appraisal, comparative market analysis, or online valuation tools. Accurate home value is crucial for determining available credit.
- 2Find Current Mortgage Balance: Check your latest mortgage statement for the outstanding principal balance. This includes first mortgage only, not other liens or second mortgages.
- 3Apply LTV Ratio: Multiply home value by the maximum loan-to-value ratio (typically 80-85%). This gives you the maximum total debt allowed against your home.
- 4Calculate Available HELOC: Subtract your current mortgage balance from the maximum allowable debt. This difference is your potential HELOC credit line.
HELOC Structure and Phases
Draw Period (5-10 years)
- • Access funds as needed up to credit limit
- • Interest-only payments on amount borrowed
- • Can repay and re-borrow multiple times
- • Variable interest rates adjust monthly
Repayment Period (10-20 years)
- • No more access to credit line
- • Principal and interest payments required
- • Higher monthly payments than draw period
- • May convert to fixed-rate option
Common HELOC Uses
Home Improvements
Finance renovations that increase home value. Interest may be tax-deductible when used for substantial home improvements.
Debt Consolidation
Pay off high-interest credit cards or personal loans with lower HELOC rates, potentially saving thousands in interest.
Emergency Fund
Keep as backup financing for unexpected expenses. No interest charged until you actually draw from the credit line.
Education Expenses
Finance college tuition or professional development. Compare rates with federal student loans before deciding.

HELOC Best Practices
Important Considerations
- Shop multiple lenders: Compare rates, fees, and terms from at least 3-5 lenders to find best deal.
- Understand rate caps: Know the lifetime cap on your variable rate to avoid payment shock.
- Plan for repayment period: Budget for higher payments when draw period ends.
- Avoid minimum payments: Pay more than interest-only to reduce principal during draw period.
- Keep records for taxes: Track HELOC use for home improvements for potential tax deductions.
- Monitor home values: Declining values could trigger loan reduction or closure.
