Three Real-World Net Worth Scenarios
Scenario A: Recent Graduate, Age 24
Amara graduated in 2023. She earns $54,000 as a healthcare administrator in Minneapolis. She has a checking account ($2,400), a Roth IRA ($4,200), and a used Honda worth $14,000. Liabilities: Student loans $38,000, car loan $6,800, credit card $1,200.
Net Worth: ($2,400 + $4,200 + $14,000) − ($38,000 + $6,800 + $1,200) = $20,600 − $46,000 = **−$25,400**
Negative net worth. Entirely normal for a 24-year-old with student debt. The Roth IRA is the most important number here — she started investing immediately, and that’s what actually matters at this stage.
Scenario B: Mid-Career, Age 41
Randall is a sales manager in Charlotte earning $97,000. Home value: $385,000. 401(k): $154,000. Roth IRA: $44,000. Savings: $22,000. Car: $28,000 (paid off). Liabilities: Mortgage $261,000. Student loans: paid off. Credit cards: $0 balance.
Net Worth: ($385,000 + $154,000 + $44,000 + $22,000 + $28,000) − $261,000 = $633,000 − $261,000 = **$372,000**
Solid — above the Fidelity 3× benchmark for his salary. Randall’s no-debt-outside-mortgage situation is the single biggest driver of his strong position.
Scenario C: Pre-Retirement, Age 57
Maria owns a home in suburban Chicago worth $610,000, mortgage balance $87,000. 401(k): $680,000. Roth IRA: $95,000. Taxable brokerage: $128,000. Rental property: $290,000 value, $142,000 mortgage. Savings: $45,000. Car: $32,000 (paid off).
Net Worth: ($610,000 + $680,000 + $95,000 + $128,000 + $290,000 + $45,000 + $32,000) − ($87,000 + $142,000) = $1,880,000 − $229,000 = **$1,651,000**
Use current market values each time you run the calculation. For investments: use today’s balance. For real estate: update once or twice a year using Zillow or a CMA from a local agent. Don’t use purchase price — it distorts your picture.
The Post-Tax Net Worth Adjustment
Your traditional 401(k) and IRA balances are pre-tax. When you withdraw in retirement, you’ll pay income tax. A $500,000 traditional 401(k) might net $375,000 after 25% effective tax rate in retirement. For a more accurate 'true' net worth, multiply tax-deferred balances by 0.70–0.85 depending on your expected retirement tax bracket.
Roth accounts have no this adjustment — they’re already tax-free.
