A single trend line that reflects every financial decision
What to take away
- Update quarterly, not daily — the trend is the information.
- Value the house conservatively and check the mortgage balance exactly.
- A falling market can reduce net worth in a quarter when you did everything right.
List everything you own at realistic value, list everything you owe, subtract. Cash, investments, retirement accounts, home equity, car; against mortgage, student loans, car loans and card balances.
Valuation discipline
- Value the home at a conservative estimate, not the optimistic one.
- Use current loan balances from statements, not what you remember borrowing.
- Exclude furniture and personal effects — they inflate the figure without being realisable.
- Count retirement accounts at face value; the future tax on traditional accounts is a footnote, not a line.
A quarterly cadence is deliberate. Monthly tracking turns market noise into emotion, and the number is a trend, not a score.
Common questions
There is no universal benchmark worth anchoring to. Compare yourself to your own figure a year ago, which is the only comparison that reflects your actual decisions.
