What This Calculator Estimates
Home equity is the difference between your home's current market value and the outstanding balance on your mortgage, representing the portion of your home you actually own outright, which grows over time both through mortgage paydown and property value appreciation. This calculator answers "how much equity do I have right now" — for "how much could I actually borrow against that equity," which lenders cap using a maximum loan-to-value ratio rather than handing over 100% of your equity, use the Equity Loan Calculator instead.

Frequently Asked Questions
How is home equity calculated?
Home equity is your home's current market value minus your outstanding mortgage balance — as you pay down the loan and/or the home's value increases, your equity grows.
Can home equity decrease?
Yes, if your home's market value declines significantly or you take on additional debt secured against the home (like a home equity loan), your equity can decrease even if you continue making mortgage payments.
What can I do with home equity?
Common options include a home equity loan (lump sum) or home equity line of credit (HELOC, flexible draw), often used for renovations, debt consolidation, or other major expenses — each has different terms and risks.
Is there a limit to how much equity I can borrow against?
Lenders typically limit borrowing to a percentage of your home's value minus your existing mortgage balance, so you generally can't borrow against 100% of your equity.
Does home value used in this calculation need to be exact?
For planning purposes, a recent appraisal or reasonable market estimate works well, though actual lending decisions typically require a formal appraisal for accuracy.
