Borrowing power

At 80% LTV

This is the standard range many lenders use for HELOC approvals and stronger pricing.

Extended borrowing range

At 90% LTV

Some lenders offer this, but higher combined LTV usually means tighter underwriting and more risk.

This calculator gives a quick estimate only. Real borrowing power depends on credit, income, debt-to-income ratio, occupancy type, appraisal results, and lender-specific HELOC or home equity loan rules.

What is home equity and how do you build it?

Home equity is the portion of your home that you truly own. It is the difference between what your home is worth today and the debt still attached to it, including your primary mortgage and any additional liens.

You build equity in two main ways. The first is paying down principal on your mortgage over time, which gradually reduces the lender's share of the property. The second is appreciation, which increases the market value of the home itself.

Equity can become a financial tool, but it is not free money. Borrowing against your home can help with renovations, debt consolidation, or emergency liquidity, but it also increases risk because your house remains the collateral behind that debt.

Frequently Asked Questions

Estimate your current home value and subtract your remaining mortgage balance plus any additional liens. The result is your current home equity.

Many lenders prefer combined LTV at or below 80% for the strongest HELOC terms, though some lenders allow borrowing up to 85% or 90% depending on credit and underwriting.

Often yes, but borrowing against equity increases risk because your home secures the debt. Common uses include renovations, debt consolidation, education, and major emergency expenses.

A HELOC works like a revolving credit line you can draw from, while a home equity loan gives you a fixed lump sum with a fixed repayment schedule.
