Why income hides the real story
Most people measure their financial life by income. 'I make $90k' is the answer to 'how are you doing financially?' But income is a flow, not a position. Two people earning the same amount can be in opposite financial situations — one is steadily building wealth, the other is steadily sinking deeper into debt. Income alone tells you nothing about which one you are. Net worth — the total of what you own minus what you owe — is the only number that captures your actual financial position.
How to calculate yours in 15 minutes
Net worth is a one-page calculation, no matter how complex your life is. You only need two columns:
- Assets — everything you own that has resale value. Checking and savings balances, investment accounts, retirement funds, your home's current market value, your car's used-market value, crypto, valuable physical items above $500.
- Liabilities — everything you owe. Credit card balances, student loans, mortgages, car loans, BNPL plans, money owed to friends or family, tax debts.
- Net worth — assets minus liabilities. That's it. The number can be negative — common for younger adults with student loans, even those with great incomes. That's not failure; it's data.
Why tracking it monthly changes behavior
A single net worth snapshot is interesting. Net worth tracked monthly is transformative. When you see the number on the 1st of every month, three things change. First, you stop celebrating raises and start celebrating net worth deltas — because only the second is real progress. Second, you start noticing the actions that move the number versus the ones that don't. Third, debt payoff stops feeling pointless because each payment visibly raises net worth, even when no money 'appears' in your accounts.
The trap of vanity assets
Be honest about what counts as an asset. A car loses 30% of its value the moment you drive it home; it should be in your tracker at realistic resale value, not purchase price. A house only counts at conservative market value minus selling costs, not at the optimistic Zillow number. Furniture, electronics, and clothes generally aren't assets — they're consumables that happen to last a few years. The point of net worth is honest measurement, not a flattering scoreboard. The harder you are on what counts, the more meaningful the upward trend becomes.
Income tells you what you're making. Net worth tells you what you're keeping. Only one of them you actually get to live on.
