📋 Net Worth: Your Financial Report Card
5 min read · 2025-03-28
Income tells you what you earn. Net worth tells you what you've kept. It's the single best indicator of your financial health — here's how to calculate and improve it.
The Simple Formula
Net worth = Total Assets − Total Liabilities
Assets: home equity, retirement accounts, savings, investments, car value, other property Liabilities: mortgage balance, car loans, student loans, credit card balances, any other debt
A positive net worth means you own more than you owe. Negative net worth is common early in a career (especially with student debt) and doesn't mean you're failing — it means you're in the building phase.
Average Net Worth by Age
According to the Federal Reserve's Survey of Consumer Finances: • Under 35: Median $39,000, Mean $183,000 • 35–44: Median $135,000, Mean $549,000 • 45–54: Median $247,000, Mean $975,000 • 55–64: Median $364,000, Mean $1.56M • 65–74: Median $410,000, Mean $1.79M
Note the large gap between median and mean — wealth is extremely concentrated. The median (middle person) is a more realistic benchmark than the mean for most people.
A Simple Net Worth Target
Thomas Stanley and William Danko's formula from "The Millionaire Next Door": Expected net worth = Age × Annual pre-tax income ÷ 10
If you're 40 earning $80,000: target $320,000. Reaching 2x this formula puts you in "prodigious accumulator of wealth" territory.
This is just a benchmark, not a judgment. High earners who started late, or those with high debt loads, will naturally lag the formula for years.
What Moves the Needle
Net worth grows through four mechanisms: 1. Saving more (increasing assets) 2. Paying down debt (decreasing liabilities) 3. Investment returns (assets growing on their own) 4. Real estate appreciation (if you own property)
High earners who spend nearly everything they earn often have surprisingly low net worth. Modest earners who save and invest consistently can build substantial wealth. The saving rate is ultimately more impactful than income.
Tracking Over Time
Net worth is most useful as a trend rather than a snapshot. Calculate it monthly or quarterly and chart the direction. A consistently rising net worth — even if the number seems small — means your financial foundation is being built. Track it in a spreadsheet or use a net worth calculator to keep a running history.
Key Takeaways
- ✓Net worth = assets − liabilities; the ultimate measure of financial progress
- ✓Negative net worth is normal in your 20s and early 30s; the trend matters more than the number
- ✓Median net worth at 45–54 is ~$247,000 (per the Fed); wide variation exists
- ✓Saving rate matters more than income — high earners can have low net worth
- ✓Track quarterly to see the trend; growth matters more than any single figure
