The **Home Equity Line of Credit (HELOC) Calculator** helps you determine the maximum line of credit you might be eligible for based on your home’s value, existing mortgage balance, and your lender’s maximum Loan-to-Value (LTV) limit. It solves for **Maximum HELOC Limit ($L_{max}$)**, **Home Value ($V_{home}$)**, **Loan Balance ($L_{balance}$)**, or **Maximum LTV (%)**, provided you enter the other three variables.

HELOC Limit Formulas & Logic
The maximum HELOC limit is derived from the maximum allowed combined loan amount (CML) and the existing mortgage balance ($L_{balance}$).
1. Maximum Combined Loan Limit (CML):
$$ CML = V_{home} \times \frac{Max LTV}{100} $$
2. Maximum HELOC Limit ($L_{max}$):
$$ L_{max} = CML - L_{balance} $$
Where $V_{home}$ is Home Value, $L_{balance}$ is Mortgage Balance, and Max LTV is the maximum allowed Loan-to-Value ratio.

What is a Home Equity Line of Credit (HELOC)?
A **Home Equity Line of Credit (HELOC)** is a revolving credit line secured by the equity in your home. Unlike a traditional mortgage, which provides a lump sum, a HELOC allows you to borrow funds as needed, up to a certain limit, during a set draw period (typically 5 to 10 years). Interest is usually only paid on the amount you actually use, not the total credit limit.
HELOCs are popular because they offer lower interest rates compared to unsecured personal loans or credit cards, as they are secured by your home. The maximum limit a lender offers is determined primarily by the home’s value ($V_{home}$), the existing loan balance ($L_{balance}$), and the lender’s internal maximum Loan-to-Value (LTV) ratio policy, typically set around 80% to 90%.
Homeowners commonly use HELOC funds for major expenses like home renovations, college tuition, or debt consolidation. It is crucial to remember that since your home serves as collateral, defaulting on the HELOC payments can lead to foreclosure, just like with a primary mortgage.
How to Calculate Maximum HELOC Limit (Example)
Scenario: Home Value is \$600,000, Mortgage Balance is \$300,000, and the lender’s Max LTV is 85%.
- Calculate Maximum Combined Loan Limit (CML):
$$ CML = V_{home} \times \frac{Max LTV}{100} = \$600,000 \times 0.85 = \$510,000 $$
- Subtract the Outstanding Mortgage Balance:
$$ L_{max} = CML – L_{balance} = \$510,000 – \$300,000 = \$210,000 $$
- Conclusion:
The Maximum HELOC Limit ($L_{max}$) is \$210,000. This is the maximum credit you can draw, ensuring the combined debt does not exceed 85% of the home’s value.
Frequently Asked Questions (FAQ)
HELOCs typically have variable interest rates based on an index (like the Prime Rate) plus a margin. Interest is only charged on the outstanding balance you have actually borrowed, not the entire line of credit.
Q: Can I use a HELOC for a down payment on a second home?While legally possible, many lenders restrict using HELOC funds for speculative investments or down payments, as it increases their risk. It is best to check with your specific lender regarding usage restrictions.
Q: What is the difference between a HELOC and a Home Equity Loan?A **HELOC** is a revolving line of credit (like a credit card), with a variable rate and flexible draw periods. A **Home Equity Loan** is a fixed-rate, lump-sum loan that is paid back in fixed monthly installments over a set term.
