Why net worth is the number that matters
Income tells you how much money passes through your life; net worth tells you how much stays. It's the single number that all your financial decisions — saving, debt payoff, investing, big purchases — ultimately move. A high earner with maxed cards can be worth less than a teacher with a paid-off car and steady 401(k) contributions; net worth is the honest scoreboard.
What to include (and what to skip)
- Include: cash, brokerage and retirement accounts, your home at current market value, vehicles at realistic resale value, and anything you could genuinely sell (and would).
- Skip: furniture, electronics, and collectibles unless they're genuinely valuable and sellable — they inflate the number without changing your real position.
- All debts count: mortgage, car loans, student loans, cards, personal loans, money owed to family.
The monthly snapshot habit
A single net worth reading is mildly interesting; a 24-month series is a financial decision-making machine. The trend shows whether your lifestyle actually fits your income, whether debt payoff is working, and what market swings do to you. It takes about five minutes a month once your accounts are listed — the habit is the hard part, which is why a pre-built tracker helps. Our Net Worth Tracker spreadsheet holds 12 asset and 8 liability accounts over 24 months with automatic totals, monthly change, and a trend chart.
Frequently asked questions
- Should I include my home in net worth?
- Yes — at current market value, with the mortgage balance as a debt. Some people also track a 'liquid net worth' excluding home equity, since you can't spend the house. Both views are useful; the trend of either is what matters.
- Is my car an asset if I have a loan on it?
- Yes: list the car's realistic resale value as an asset and the loan balance as a debt. If the loan exceeds the value, you're 'underwater' on it and the calculator will show that honestly.
- What's a good net worth for my age?
- Benchmarks vary hugely with income and country; a popular rule of thumb is to aim for 1× your annual salary saved by 30, 3× by 40, 6× by 50. Treat benchmarks as loose orientation — your own 12-month trend is the better measure.
- How often should I update it?
- Monthly. Weekly amplifies market noise; yearly is too slow to catch drift. Month-end takes five minutes and matches statement cycles.
