A Home Equity Line of Credit (HELOC) is one of the most flexible ways homeowners can borrow money using the value of their property. Whether you’re planning home renovations, consolidating debt, funding education, or preparing for unexpected expenses, knowing how much equity you can access is crucial. That’s exactly where our Equity Line of Credit Calculator comes in.
This powerful yet simple tool helps you instantly estimate your maximum loan amount and available HELOC credit based on your home value, current mortgage balance, and lender-approved loan-to-value (LTV) ratio. No guesswork, no complex math—just clear numbers you can use to make informed financial decisions.

What Is a Home Equity Line of Credit (HELOC)?
A HELOC is a revolving credit line secured by your home’s equity. Home equity is the difference between your home’s market value and the amount you still owe on your mortgage. Unlike a traditional loan, a HELOC allows you to borrow, repay, and borrow again up to an approved limit during a draw period.
Lenders typically cap borrowing at a certain loan-to-value (LTV) percentage, often between 70% and 85%. This means the combined total of your mortgage and HELOC cannot exceed that percentage of your home’s value.
Understanding these limits is essential—and that’s where our calculator becomes invaluable.
Why Use an Equity Line of Credit Calculator?
Manually estimating HELOC eligibility can be confusing. Different lenders use different LTV limits, and homeowners often forget to factor in their remaining mortgage balance.
Our Equity Line of Credit Calculator helps you:
- Estimate how much you may be allowed to borrow
- Understand how your mortgage balance affects available credit
- Plan finances with realistic borrowing expectations
- Compare different LTV scenarios before contacting lenders
- Avoid overestimating your home equity access
It’s fast, free, and designed for homeowners at any stage of ownership.
How the Equity Line of Credit Calculator Works
The calculator uses three key inputs:
1. Home Value
This is your property’s current market value. You can use a recent appraisal, comparable sales, or an online home valuation estimate.
2. Current Mortgage Balance
This is the amount you still owe on your existing mortgage. The calculator subtracts this from the maximum loan limit to find available credit.
3. Allowed LTV Percentage
Lenders set a maximum LTV percentage that determines how much of your home’s value can be borrowed against. Common values are 75%, 80%, or 85%.
Behind the Calculation
- Maximum Loan Amount = Home Value × (LTV ÷ 100)
- Available Credit = Maximum Loan Amount − Current Mortgage Balance
If the result is negative, available credit is shown as zero, meaning you currently don’t have usable equity for a HELOC.
How to Use the HELOC Calculator (Step-by-Step)
Using this tool is straightforward and takes less than a minute:
- Enter your home’s estimated value
- Enter your current mortgage balance
- Input the allowed LTV percentage
- Click Calculate
- Instantly view:
- Maximum Loan Amount
- Available Credit
If you want to try different scenarios, simply reset the calculator and adjust the values.
Example: HELOC Calculation in Real Life
Let’s walk through a practical example.
- Home Value: $400,000
- Current Mortgage Balance: $220,000
- Allowed LTV: 80%
Step 1:
Maximum Loan Amount = $400,000 × 0.80 = $320,000
Step 2:
Available Credit = $320,000 − $220,000 = $100,000
Result:
You may qualify for up to $100,000 in HELOC credit, depending on lender approval and other financial factors.
