Net worth is the truest scoreboard
Income comes and goes. Spending fluctuates. Net worth — what you own minus what you owe — is the single number that quietly tracks whether you're actually building wealth. Run it once a quarter and watch the trend, not the month-to-month wobble.
What to count
Assets: checking and savings, brokerage and retirement accounts (use current balance), home and car (use realistic market value, not what you paid), and anything else you could sell. Liabilities: mortgage balance, car loans, student loans, credit-card balances. Don't count future expenses or things you intend to buy.
