Yes, your mortgage is part of your net worth calculation. The house itself counts as an asset at its current market value, and the outstanding mortgage balance counts as a liability. The gap between the two is your home equity, and for most homeowners it’s the single biggest piece of the net worth picture.
Where the Home and Mortgage Sit in the Formula
Net worth is everything you own minus everything you owe. Assets include cash, retirement and brokerage accounts, vehicles, and real estate. Liabilities include credit card balances, student loans, auto loans, personal loans, and any remaining mortgage balance. The mortgage is simply the largest liability most people carry, which is why it dominates the question.
Your home enters the equation on both sides. Put the full market value on the asset side and the full mortgage balance on the liability side. Don’t shortcut by listing only the equity as an asset. The bottom-line number comes out the same either way, but keeping the two entries separate shows you how much wealth is locked up in an illiquid asset and how much debt you’re actually carrying. That split matters when you want to track changes year over year.
Getting the Home Value Right
Use current fair market value, not what you paid. The IRS defines fair market value as what a willing buyer would pay a willing seller when both know the relevant facts. In many markets, the purchase price from a few years ago has little to do with the number today.
You have three practical options for coming up with that number:
- Automated online estimates from services like Zillow, Redfin, or Realtor.com. These are free and instant. Zillow’s own reporting puts its median Zestimate error at around 4.3%, which on a $400,000 home can mean being off by roughly $17,000.
- Comparable sales in your immediate neighborhood. Free, and often more accurate than an algorithm if you’re careful about which sales are actually comparable.
- A professional appraisal, typically $450 to $1,200 for a residential property. Overkill for casual tracking, but worth it when a real financial decision depends on the number.
For annual net worth tracking, an online estimate is usually fine. Pick one source and stick with it so your year-over-year numbers stay comparable even if the absolute figure isn’t perfect.
Getting the Mortgage Balance Right
Use the current remaining balance, not the original loan amount. If you borrowed $300,000 five years ago, you’ve been paying principal down ever since, and only what’s left today belongs on the liability side.
Strictly speaking, the most accurate figure is the payoff amount rather than the principal balance on your monthly statement. Those two numbers are different. The payoff includes accrued interest through the actual payoff date and may include other fees. As the Consumer Financial Protection Bureau puts it, your statement balance “might not reflect how much you actually owe to completely satisfy the outstanding loan balance.”1Consumer Financial Protection Bureau. What Is a Payoff Amount and Is It the Same as My Current Balance?
For everyday net worth tracking, the principal balance from your most recent statement is close enough. If the calculation is going into a loan application, a legal filing, or a major financial decision, request a formal payoff statement from your servicer. Servicers are required to provide an accurate payoff figure when you ask for one.1Consumer Financial Protection Bureau. What Is a Payoff Amount and Is It the Same as My Current Balance?
A Worked Example
Here’s how it looks for a typical homeowner.
Assets:
- Home at fair market value: $400,000
- 401(k): $85,000
- Savings: $15,000
- Vehicle: $12,000
Liabilities:
- Mortgage balance: $250,000
- Student loans: $18,000
- Credit card debt: $5,000
Total assets are $512,000. Total liabilities are $273,000. Net worth comes to $239,000. The home contributes $150,000 in equity, which is nearly two-thirds of the total. Federal Reserve data shows that ratio is fairly typical for American homeowners.
How the Split Shifts as You Pay Down the Mortgage
Every mortgage payment splits into interest and principal. Only the principal portion reduces your mortgage balance and, in turn, lifts your net worth. Early in a loan, most of the payment goes to interest.
On a $350,000 mortgage at 6.375%, the first monthly payment sends about $324 to principal and $1,859 to interest. Roughly 85% of that early payment does nothing for your net worth. It takes about 19 years before more of each payment goes to principal than to interest. That’s the reason net worth tends to accelerate once a homeowner has been in place for a decade or more: the amortization curve finally tips.
Market appreciation compounds on top of principal paydown. In flat or declining markets, principal payments are the only thing building equity.
When You’re Underwater
If your mortgage balance is larger than the home’s current market value, you have negative equity. The home still goes on both sides of the equation, but instead of lifting net worth, it pulls it down. A home worth $300,000 with a $350,000 mortgage subtracts $50,000 from your net worth.
Negative equity doesn’t automatically mean your total net worth is negative. Other assets may more than offset it. It does mean the home is currently a net liability rather than a net asset. This usually stems from a market downturn, a very small down payment before prices fell, or home equity borrowing that pushed total debt above the property’s value. Home values recover over time in most markets, and monthly principal payments keep chipping away at the balance in the meantime.
Optional Adjustments for a More Realistic Picture
The standard calculation uses face-value numbers, and that’s the right approach for consistent tracking. Some people prefer a more conservative version that reflects what they’d actually keep if they liquidated.
Selling Costs
Selling a home isn’t free. Commissions average around 5–6% of the sale price nationally, and seller closing costs add another 1–3% depending on location. On a $400,000 home, that’s $24,000 to $36,000 you wouldn’t pocket. Most financial planners don’t deduct hypothetical selling costs, because you’re not actually selling. If you’re close to retirement and planning to downsize, factoring them in gives a more honest picture of what you’ll have to work with.
Taxes on Retirement Accounts
A traditional 401(k) or IRA balance isn’t entirely yours on paper either. Withdrawals get taxed as ordinary income, so the government’s share in retirement could run 15–30% or more depending on your bracket. Some people discount tax-deferred balances by an estimated rate; others track the gross and handle taxes later. Either works if you’re consistent. Roth balances have already been taxed and generally come out tax-free in retirement.
Capital Gains on the Home
If your home has appreciated substantially, you may owe capital gains tax when you sell, but only on gain above a generous exclusion. Federal law excludes up to $250,000 of gain for single filers and $500,000 for married couples filing jointly, provided you owned and lived in the home for at least two of the five years before the sale.2Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence Most homeowners never owe capital gains tax on a primary residence. If your gain exceeds the exclusion, IRS Publication 523 walks through the eligibility rules and worksheets.3Internal Revenue Service. Publication 523 – Selling Your Home
The Big Exception: Accredited Investor Rules
One context deliberately leaves the home and its mortgage out of the calculation. To qualify as an accredited investor under SEC rules, which opens access to certain private investments, hedge funds, and startup rounds, you need net worth above $1 million. But the SEC requires you to exclude your primary residence from the asset side entirely.4U.S. Securities and Exchange Commission. Accredited Investor Net Worth Standard
The mortgage side has its own rules. Debt secured by your primary residence generally doesn’t count as a liability either, as long as it doesn’t exceed the home’s fair market value. Two exceptions apply:
- Negative equity. If you owe more on the mortgage than the home is worth, the excess counts as a liability.
- Recent borrowing. If you increased debt secured by your home in the 60 days before an investment purchase, by taking out a home equity loan or a cash-out refinance, that increase counts as a liability even if the home is still worth more than the total debt.
These rules trace to the Dodd-Frank amendments of 2010 and are codified in SEC Regulation D.5eCFR. 17 CFR 230.501 – Definitions and Terms Used in Regulation D The 60-day lookback exists to stop people from borrowing against a home to inflate liquid net worth right before a qualifying investment. Income-based qualification ($200,000 individually or $300,000 jointly for two straight years) is an alternative path that skips the net worth test entirely.
Outside that specific SEC context, though, the answer holds: your home is an asset, your mortgage is a liability, and both belong in the calculation.
