Home Equity and Net Worth: How Your House Fits Into the Number
Home equity makes up the largest share of most American households' net worth. Here's how to value it, what to count, and why some planners separate it.
Home equity is the largest single component of net worth for most middle-class American households. The median homeowner has roughly 40% of their wealth in home equity. Understanding how it's calculated, how to value it, and how it fits into your overall picture is foundational to honest net worth tracking.
The formula
Home equity = current market value − current mortgage balance. If your home is worth $450,000 and you owe $280,000, your equity is $170,000. Both numbers move every month: the home's value with market conditions, the mortgage balance with each payment.
How to value the home
Three options, in increasing accuracy. Zillow/Redfin/Realtor estimates: fast and free, accurate within ±10%. Recent comparable sales (last 90 days): more accurate but takes effort. Formal appraisal: most accurate, $400–$600, only needed for major decisions. For monthly tracking, Zillow estimates are fine; review formally once a year.
Subtract selling costs (for honest tracking)
If you sold today, you'd pay 5–6% to agents, plus closing costs and possibly capital gains tax. Conservative trackers reduce home equity by 7–8% to reflect realizable value. This is optional but it gives a more honest 'what could I actually access' number.

Home equity is real wealth but illiquid. You can't easily spend it; tapping it requires selling (months) or borrowing (a HELOC with a new payment). Many planners track 'investable net worth' separately — net worth minus home equity and personal property — to focus on the assets that fund actual lifestyle.
The principal-paydown effect
Each mortgage payment shifts dollars from your bank account to your home equity. This isn't 'savings' in the cash-flow sense, but it absolutely grows net worth. Many homeowners underestimate how much net worth growth this represents — a $2,000/month mortgage payment includes $400–$1,500 of principal reduction depending on loan stage.
When home equity becomes a problem
If 70%+ of your net worth is home equity, you have a concentration problem. Diversification into liquid investments matters: a market drop in home values can erase years of net worth growth, and you can't easily rebalance. As home equity grows past 30–40% of net worth, redirect savings toward liquid investments.
