HELOC Credit Limit Calculator

Estimate how much equity you can borrow from your home.

Standard is 80%, some lenders allow up to 90%.

Calculation Summary

Total Max Loan Amount: $0
Current Debt: $0
Estimated HELOC Limit: $0

How Does a HELOC Limit Calculation Work?

A Home Equity Line of Credit (HELOC) is a revolving line of credit that uses your home as collateral. Unlike a standard home equity loan, a HELOC allows you to borrow, repay, and borrow again during a set period (the "draw period").

Understanding Combined Loan-to-Value (CLTV)

Lenders use the Combined Loan-to-Value (CLTV) ratio to determine how much you can borrow. This ratio represents the total of all loans on your home (your first mortgage plus the requested HELOC) divided by the home's appraised value.

The standard formula used by our calculator is:

(Home Value × Max LTV Percentage) – Outstanding Mortgage Balance = HELOC Limit

Real-World Example

Imagine your home is currently worth $500,000 and you still owe $300,000 on your primary mortgage. If your lender allows for an 85% CLTV, the calculation would look like this:

  • Total borrowing capacity: $500,000 × 0.85 = $425,000
  • Subtract current mortgage: $425,000 – $300,000 = $125,000
  • Result: Your estimated HELOC credit limit is $125,000.

What Impacts Your HELOC Eligibility?

While the calculator provides a mathematical limit based on equity, lenders also consider the following factors during the approval process:

  • Credit Score: High scores (typically 700+) secure the best interest rates.
  • Debt-to-Income (DTI) Ratio: Lenders prefer your total monthly debt payments to be below 43% of your gross monthly income.
  • Appraisal: A professional appraisal is usually required to confirm the current market value of your property.
  • Income Stability: Proof of consistent employment and income is mandatory.
