How to Calculate Your Net Worth
Net worth = total assets minus total liabilities. List everything you own that has monetary value (assets) and everything you owe (liabilities). Calculate the difference. A positive net worth means assets exceed debts. A negative net worth (common early in life with student loans) is a starting point, not a permanent state.
- Assets: Bank accounts, investment accounts, 401k/IRA value, home equity (market value minus mortgage), car value, other valuable property
- Liabilities: Mortgage balance, car loan balance, credit card balances, student loans, personal loans, any other debt
- Net worth = total assets minus total liabilities
- Track quarterly: run the calculation at the end of each quarter to see the trend
- Focus on the trend: monthly net worth fluctuates with investment values; the multi-year trend is what matters
- Benchmark: Fidelity suggests 1x your annual salary in savings by 30, 3x by 40, 6x by 50, 8x by 60
At a 20% savings rate on $80,000 gross ($13,000/year invested), net worth reaches $100,000 in approximately 7 years. After that, investment returns begin to rival new contributions. By year 15, annual investment returns exceed new contributions. By year 30, the portfolio is largely self-generating wealth through compounding.
Setting Net Worth Milestones Alongside Your Budget
Connecting budget decisions to net worth milestones creates motivation that abstract budget goals lack. Instead of 'save $500/month,' the goal becomes 'reach $100,000 net worth by age 33.' Instead of 'reduce debt,' it becomes 'eliminate all consumer debt by June 2026 to grow net worth by $18,000.' Specific, date-bound net worth milestones make budgeting feel purposeful rather than restrictive.
