Monitoring total assets minus liabilities (net worth = what you own - what you owe) as primary financial health metric, popularized by FIRE movement and wealth-tracking apps (Personal Capital, Mint, Empower).
Why Net Worth > Income
- $200K income with $300K debt = -$100K net worth (living paycheck-to-paycheck)
- $60K income with $400K paid-off house + $200K investments = $600K net worth (financially secure)
Income is flow; net worth is scoreboard. “You can’t out-earn stupid spending.”
Monthly Tracking Ritual
FIRE community spreadsheets updated monthly:
- Assets: Retirement accounts, taxable brokerage, home equity, car value, cash
- Liabilities: Mortgages, student loans, car loans, credit cards
- Net worth = Assets - Liabilities
Graph over time shows trajectory toward FIRE number. r/financialindependence members share milestone screenshots: $0 → $100K → $500K → $1M+.
Personal Capital Phenomenon
Free app (launched 2011) aggregated all accounts:
- 401k, IRAs, checking, credit cards, mortgages, loans
- Automatic net worth dashboard
- Investment fee analyzer (exposed how much advisors charged)
- Retirement planner (Monte Carlo simulations)
Became default FIRE tool until Empower acquisition (2020) and feature degradation.

- $0 net worth: Out of debt (positive net worth)
- $100K: First six figures (hardest milestone, compound interest accelerates after)
