How the Net Worth Calculator Works
Net worth is the single best one-number summary of your financial position. The formula is straightforward: total assets minus total liabilities. The hard part is being honest about both sides.
Honest asset values
For market-priced assets like brokerage accounts and retirement accounts, use today's balance. For your home, use a conservative recent estimate from Zillow or Redfin, not the peak price you remember. For vehicles, use Kelley Blue Book trade-in value, not private-party. Conservative numbers prevent the wishful-thinking version of net worth.
Honest liability values
Use the actual current payoff balance on each debt. Credit card balances should be the full statement balance, not the minimum due. Mortgages should be the principal balance from your most recent statement.
Tracking over time matters more than the number itself
Net worth at a single moment is interesting; net worth over years is the actual story. Save a quarterly snapshot in a spreadsheet or notes app. After two or three years you will have a clear picture of which months and habits move the needle and which don't.
How to compare to peers
The Federal Reserve's Survey of Consumer Finances publishes median net worth by age group. The 2022 data: $39,000 under age 35, $135,600 ages 35-44, $247,200 ages 45-54, $364,500 ages 55-64. Always use the median, not the mean - the mean is distorted by a small number of extremely wealthy households.
A worked example: calculating your number
Net worth is simply everything you own minus everything you owe. Suppose your assets are a home worth $300,000, $80,000 in retirement accounts, $20,000 in savings, and a $15,000 car – $415,000 total. Your liabilities are a $240,000 mortgage, an $8,000 car loan, and $20,000 in student loans – $268,000 total. Your net worth is $415,000 minus $268,000 = $147,000. That single number is the clearest snapshot of your financial health there is.
When to use the net worth calculator
- Annual checkups: calculate it once a year (or quarterly) to see whether you are moving in the right direction.
- Tracking progress: a rising net worth means you are building wealth even in months that feel tight.
- Debt payoff motivation: watch the number climb as balances fall.
- Big decisions: understand your full financial picture before a major purchase or investment.
Common mistakes to avoid
- Overvaluing your home or car. Use realistic current market values, not what you paid or hope to get.
- Forgetting liabilities. Include every debt – credit cards, student loans, personal loans – for an accurate number.
- Obsessively comparing to others. The trend that matters most is your own, over time.
- Counting money twice or including things you cannot realistically sell.

Frequently Asked Questions
What counts as an asset?
Anything you own that has monetary value: cash, savings, investments, retirement accounts, your home's market value, vehicles, valuable collectibles, and money owed to you.
What counts as a liability?
Anything you owe: mortgage balance, auto loans, student loans, credit card balances, personal loans, business debt.
Should I include my home in net worth?
Yes - use current market value as the asset and mortgage balance as the liability. "Investible net worth" calculations sometimes exclude the primary residence.
What is a healthy net worth?
It depends on age. Federal Reserve data puts the median at $192,700 for ages 35-44 and $364,500 for 55-64 (2022 Survey of Consumer Finances).
How often should I update my net worth?
Quarterly is plenty. Tracking too frequently invites stress over normal market volatility.
