How to Calculate Your Home Equity Loan Limit

A home equity loan, often called a "second mortgage," allows you to borrow a lump sum of money using your home as collateral. Lenders typically allow you to borrow up to a certain percentage of your home's appraised value, minus what you still owe on your primary mortgage.

The 80% Rule Explained

Most traditional lenders utilize an 80% to 85% Combined Loan-to-Value (CLTV) limit. This means your total debt (existing mortgage + new home equity loan) cannot exceed 80% of your home's current market value.

Real-World Example:
  • Home Value: $500,000
  • Current Mortgage: $300,000
  • LTV Limit (80%): $400,000
  • Maximum Loan: $400,000 – $300,000 = $100,000

Home Equity Loan vs. HELOC

While both use your home as collateral, they function differently:

  • Home Equity Loan: Fixed interest rate, fixed monthly payments, and a lump sum payout. Best for specific projects like roof replacement or debt consolidation.
  • HELOC (Line of Credit): Variable interest rate, flexible borrowing (like a credit card), and interest-only payment options during the draw period.

Factors That Affect Your Borrowing Power

  1. Debt-to-Income (DTI) Ratio: Most lenders prefer a DTI below 43%.
  2. Credit Score: Higher scores (740+) unlock lower interest rates and higher LTV limits.
  3. Appraisal: A professional appraisal will determine the final "Value" used in the calculation.
