How to track your net worth

Net worth is the single clearest snapshot of your financial progress: total assets minus total liabilities. Tracking it quarterly for 5 years will tell you more about whether your financial decisions are working than any budgeting app. This guide covers what to include (and what to leave out), how to value tricky assets, how often to update, and the handful of numbers that tell you if you’re on pace for major life milestones.

The formula — and what it really measures

Net worth = Assets − Liabilities.

Assets are things you own that have resale value. Liabilities are things you owe. The number itself is less important than its direction over time — a single snapshot can mislead, but a 5-year trendline cannot.

A 32-year-old with $8,000 net worth but +$20,000 YoY growth is doing better than a 55-year-old at $400,000 with flat or declining change, because trajectory matters more than altitude.

What counts as an asset — and at what price

Cash and near-cash. Checking, savings, money market, CDs. Value = balance. Easy.

Investment accounts. 401(k), IRA, brokerage, HSA, 529. Value = current market value of holdings, pre-tax for traditional accounts. Some methodologies adjust 401(k) down by expected tax (e.g., count $100k traditional 401(k) as $75k post-tax). Either approach works as long as you’re consistent.

Real estate. Home, rental properties, land. Value = current market value (Zillow/Redfin estimate minus ~3% for selling costs, or a recent appraisal). Subtract the mortgage as a liability.

Vehicles. Use Kelley Blue Book private-party value, not what you paid. A car bought for $40k 3 years ago might be worth $22k today; don’t count the $40k.

Business ownership. Tricky. If you have a salable business, use a conservative 1–2× annual SDE (seller’s discretionary earnings) or a recent valuation. Don’t count unrealizable hypotheticals.

Crypto. Current market value. Volatile; update at each snapshot.

What NOT to count (or count carefully)

Furniture, clothes, books. These have near-zero resale value. Don’t inflate your net worth with them.

Jewelry, art, collectibles. Only if appraised recently and genuinely salable at that price — “worth $10k” that can’t actually sell isn’t worth $10k.

Unvested stock options / RSUs. Not yours yet. Some methodologies include vested-but-unexercised at strike-to- market difference; that’s acceptable if conservative.

Pension (defined benefit). Can be the largest asset for some people. Value it at the NPV of expected payments, or at minimum flag its existence.

Social Security expected benefits. Usually excluded from personal net worth — no market value before eligibility.

The liabilities list

Mortgage. Remaining principal balance (not original loan amount).

Auto loans. Remaining balance.

Student loans. Remaining balance. Include both federal and private.

Credit card balances. Only the amount not paid off at the next statement cycle. If you pay in full monthly, balance is effectively zero for this purpose.

Personal loans, medical debt, tax owed, IOUs.Add them all. Liabilities aren’t embarrassing — they’re data.

How often to track

Quarterly is the sweet spot. Monthly creates noise from market volatility; annual misses course-correction windows. Quarterly gives you 4 data points a year, enough to see a trend within 12 months.

Set a recurring calendar event on the 1st of each quarter, take 30 minutes, update one spreadsheet or calculator. Done.

Benchmarks that are actually useful

Fidelity’s milestones (imperfect but directionally useful):

Age 30: 1× annual salary in retirement accounts.

Age 40: 3× annual salary.

Age 50: 6× annual salary.

Age 60: 8× annual salary.

Age 67: 10× annual salary.

These are rules of thumb for W-2 earners with Social Security supplement. If you’re self-employed, want early retirement, or want higher lifestyle in retirement, you need more.

The simpler Stanley/Danko formula (from The Millionaire Next Door): expected net worth = age × pre-tax income ÷ 10. A 40-year-old earning $80k should have $320k net worth to be “on track.” Above 2× that = “prodigious accumulator.” Below 0.5× = “under accumulator.”

What the direction tells you

Growing every quarter, even a little: you’re saving and investing. System is working. Stay the course.

Flat or declining in a flat market: spending is eating income, or lifestyle inflation after raises. Review budget and savings rate.

Dropped 20%+ in a market crash: normal. Don’t change strategy; don’t sell. 30–40% drawdowns happen roughly once a decade and recover within 1–3 years.

Up substantially in a bull market: don’t confuse luck with skill. Bull markets make everyone look smart. Rebalance; don’t increase risk.

The two ratios worth watching

Debt-to-assets ratio = Total liabilities / Total assets. Below 0.30 is healthy; above 0.50 is stretched.

Liquid net worth = Cash + investments − all debt. Excludes home equity (not liquid). This is the “if I lost my job tomorrow, what would I actually have” number. Healthy: at least 6 months of essential expenses.

Run the numbers

List your assets and liabilities in the net worth calculator to get your snapshot. Pair with the savings goal calculator for the “how do I get there” side, and the compound interest calculator to project where disciplined saving gets you over 10, 20, 30 years.
