What is Net Worth and Why It Matters
Net worth is the single most important number in personal finance. It represents your true financial position: everything you own minus everything you owe. Unlike income — which measures cash flow — net worth measures wealth accumulation over time.
A high income does not guarantee high net worth. Someone earning $200,000 per year but spending $210,000 has a declining net worth. Someone earning $60,000 but consistently saving and investing can build substantial wealth over decades.
The Net Worth Formula
Assets include everything with monetary value you own: cash, investments, retirement accounts, real estate, vehicles, and valuables. Liabilities are all outstanding debts: mortgage, auto loans, student loans, credit cards, and personal loans.
Average Net Worth by Age (US, 2023)
| Age Group | Median Net Worth | Mean Net Worth |
|---|---|---|
| Under 35 | $39,000 | $183,000 |
| 35–44 | $135,000 | $549,000 |
| 45–54 | $247,000 | $975,000 |
| 55–64 | $365,000 | $1,567,000 |
| 65–74 | $410,000 | $1,795,000 |
Median is more meaningful than mean here — a small number of very wealthy individuals skew the average significantly upward. Focus on your trend over time rather than comparisons to others.
Building Net Worth: The Two Levers
Net worth grows through two mechanisms: increasing assets (saving and investing) and decreasing liabilities (paying down debt). Both matter. Eliminating high-interest debt is often more valuable than adding to investments because the guaranteed "return" of eliminating 20% credit card debt exceeds most investment returns.
