Short answer
Home equity is commonly estimated as home value minus mortgage balances. Available borrowing is usually lower than total equity because lenders may limit combined loan-to-value, review credit and income, verify property value, and apply state or product rules.
How the estimate works
This calculator uses the existing production formula: estimated available borrowing room = estimated home value x 85% minus current mortgage balance, floored at zero. The 85% CLTV assumption is an illustrative example, not a universal lender rule.
What is home equity?
Home equity is the difference between what a home may be worth and what is owed against it. For example, a home valued at $450,000 with a $270,000 mortgage balance has $180,000 of gross equity before lender limits, fees, or other requirements.
LTV vs CLTV
| Term | What it compares | Why it matters |
|---|---|---|
| LTV | One loan balance compared with property value. | Often used to understand the current first mortgage position. |
| CLTV | All loans secured by the property compared with property value. | Commonly used when evaluating home equity loans or HELOCs. |

| $350,000 | $210,000 | $140,000 | 85% | $87,500 | $52,500 |
| $450,000 | $270,000 | $180,000 | 85% | $112,500 | $67,500 |
| $600,000 | $360,000 | $240,000 | 85% | $150,000 | $90,000 |
| $750,000 | $450,000 | $300,000 | 85% | $187,500 | $112,500 |
| $1,000,000 | $620,000 | $380,000 | 85% | $230,000 | $150,000 |
Methodology and limitations
Gross equity = home value minus mortgage balance. Illustrative borrowing capacity = max(0, home value x 85% - mortgage balance). Remaining equity = gross equity minus illustrative borrowing capacity. This does not include credit review, income review, DTI, property verification, lien review, fees, state availability, or lender-specific limits.
For a deeper CLTV breakdown, use the LTV / CLTV Calculator. To understand payment impact after drawing funds, use the HELOC Payment Calculator.
How mortgage balances affect equity
Higher existing mortgage balances reduce available equity because more of the home's value is already pledged to existing debt. Existing second mortgages or HELOC balances can also affect combined loan-to-value.

Frequently Asked Questions
Can I borrow all of my home equity?
Usually no. Lenders may apply CLTV limits and review credit, income, property, state, and other requirements.
Does a higher home value always mean approval?
No. Home value is only one part of review. Partners may also evaluate mortgage balances, credit profile, income, DTI, and property details.
Does this calculator change my application?
No. It only changes the educational page content. The existing application and partner review process remain unchanged.
