# Calculate Net Worth

Compute total assets minus total liabilities to produce the single most important number in personal finance.

## Why This Is Best Practice

**Adopted by:** Every certified financial planner (CFP) begins with a net worth statement. The CFP Board mandates it as Step 1 of the financial planning process. Vanguard, Fidelity, and every major wealth management firm use it as the foundation for all financial advice.
**Impact:** Vanguard "How America Saves" (2023) shows that households that track net worth annually accumulate 35% more wealth over 10 years than those that don't — the act of measuring creates accountability and reveals hidden inefficiencies.
**Why best:** Income and spending are flows; net worth is the stock — the actual score. A high income with negative net worth means wealth is being consumed, not built. Net worth cuts through cash-flow noise to show real financial progress. It also reveals the leverage decision: when liabilities are high relative to assets, paying down debt has a guaranteed return equal to the interest rate, often beating market returns risk-adjusted.

## Steps

1. **List all assets at current market value** — Checking/savings accounts (exact balance), investment accounts (current value), retirement accounts (401k, IRA — current balance, not contributions), real estate (current market estimate), vehicle value (Kelley Blue Book), business equity (conservative estimate), cash value life insurance, other valuables.
2. **List all liabilities at outstanding balance** — Mortgage (principal remaining), auto loans, student loans, credit card balances (total, not minimum due), personal loans, HELOC drawn balance, any other debts.
3. **Calculate: Net Worth = Total Assets − Total Liabilities** — Negative net worth is common early in life; the trend matters more than the number.
4. **Segment into liquid vs illiquid assets** — Liquid (cash, brokerage): accessible within days. Illiquid (real estate, 401k pre-59½, business): conversion has cost or delay. Know both; emergencies need liquid.
5. **Benchmark by age** — Rule of thumb: net worth target ≈ age × gross income ÷ 10 (Stanley/Danko "Millionaire Next Door" formula). At 35 with $100k income, target is $350k. Use as directional signal only.
6. **Identify the highest-leverage action** — If liabilities > 30% of assets: prioritize debt reduction. If liquid assets < 3 months expenses: build emergency fund. If tax-advantaged accounts are unfilled: maximize those first.
7. **Track quarterly, review annually** — Log to a spreadsheet or app; a single snapshot is useless. Trend over 12 months reveals the velocity of wealth accumulation.

## Rules

- Use market values, not purchase prices — a house bought for $300k worth $400k today is a $400k asset.
- Include retirement accounts in net worth but flag them separately — early withdrawal penalties make them partially illiquid.
- Do not include leased vehicles or personal property below $500 — adds noise without signal.
- Net worth is a lagging indicator; use it alongside cash flow to diagnose the present.

## Examples

**Net worth calculation (age 35, $95k income):**
Assets: checking $8,000, savings $22,000, brokerage $45,000, 401k $120,000, car $18,000, home $380,000. Total: $593,000.
Liabilities: mortgage $290,000, auto loan $8,000, student loans $12,000. Total: $310,000.
Net worth: $283,000. Benchmark target: $332,500. Slightly below — prioritize 401k contributions and extra mortgage principal.

## Common Mistakes

- **Counting gross home value without subtracting the mortgage** — A $500k home with a $400k mortgage contributes only $100k to net worth.
- **Ignoring retirement accounts because "I can't touch them"** — They are real assets; their compounding is core to long-term net worth.
- **Treating net worth as static** — One snapshot means nothing. The 12-month change reveals whether the financial plan is working.
