Net worth is the closest thing personal finance has to a scoreboard. Unlike income, which measures cash flow in a given period, net worth measures accumulated financial position at a single point in time — a snapshot of everything you've built (or still owe) so far.
The Formula
Worked Example
Consider a household with the following financial picture:
| Assets | Value |
|---|---|
| Checking + savings | $15,000 |
| 401(k) / retirement accounts | $85,000 |
| Home value | $380,000 |
| Vehicle (resale value) | $12,000 |
| Total Assets | $492,000 |
| Liabilities | Value |
|---|---|
| Mortgage balance | $260,000 |
| Auto loan | $8,000 |
| Credit card balances | $3,500 |
| Student loans | $18,000 |
| Total Liabilities | $289,500 |
Net Worth = $492,000 − $289,500 = $202,500. That's the single number that represents this household's overall financial health at this moment.
Why Tracking Net Worth Matters More Than Income
A high earner who spends everything can have a lower net worth than a modest earner who saves consistently. Tracking net worth over time — quarterly or annually — reveals whether your financial decisions (saving, paying down debt, investing) are actually compounding into real wealth, regardless of what your paycheck looks like.
It's completely normal for net worth to be negative early on, especially with student loans or a recent home purchase with a large mortgage. What matters is the trend line moving upward over years, not any single snapshot.
