Net worth is the single most useful number in personal finance, and it’s one subtraction: everything you own minus everything you owe. It cuts through noise that income can’t. A $150,000 earner with maxed-out cards and no savings can have a lower net worth than a $55,000 earner who’s been steadily paying down a mortgage.
The formula is trivial. The execution — what counts, how to value things, how often to update — is where people get stuck. This guide walks the whole process with a worked example you can copy.
Step 1: List Everything You Own (Assets)
An asset is anything with real, sellable value. Work through these categories and write down a current value for each:
- Cash and bank accounts — checking, savings, money market, CDs. Use today’s balances.
- Retirement accounts — 401(k), 403(b), IRA, Roth IRA, pension cash value. Use the current statement balance, not what you contributed.
- Investment accounts — brokerage accounts, robo-advisors, HSA investments.
- Your home — if you own it, use a realistic market value. An online estimate (Zillow, Redfin) is fine; when in doubt, round down.
- Vehicles — use the private-party value from Kelley Blue Book or Edmunds, not what you paid.
- Other real property — rental property, land, a paid-off boat or trailer.
- Money owed to you — only if you genuinely expect repayment.
What to skip: furniture, electronics, clothes, and most collectibles. Their resale value is a fraction of purchase price, and inflating your net worth with a $3,000 “value” for a couch defeats the purpose. Exception: items with a real resale market and meaningful value — a documented coin collection, a second car, quality tools.
Step 2: List Everything You Owe (Liabilities)
This side is easier because lenders keep score for you. Pull current payoff balances for:
- Mortgage — remaining principal, from your servicer’s site
- Auto loans — payoff amount, not the sum of remaining payments
- Student loans — every servicer, every loan
- Credit cards — current statement balances
- Personal loans and buy-now-pay-later balances — these count, and people forget them
- Money owed to family, medical bills on payment plans, tax debt
Use payoff balances, not monthly payments. Your $450 car payment is irrelevant here; the $9,400 you’d need to close the loan today is the number.
Step 3: Subtract — a Full Worked Example
Here’s a complete example calculation. These are illustrative numbers for a fictional household, not benchmarks — your list will be shorter or longer.
| Assets | Value |
|---|---|
| Checking account | $3,200 |
| Savings / emergency fund | $8,500 |
| 401(k) | $42,000 |
| Roth IRA | $11,500 |
| Brokerage account | $4,800 |
| Car (private-party value) | $14,000 |
| Home (estimated market value) | $310,000 |
| Total assets | $394,000 |
| Liabilities | Balance |
|---|---|
| Mortgage principal | $248,000 |
| Car loan payoff | $9,400 |
| Credit cards | $4,100 |
| Student loans | $18,600 |
| Total liabilities | $280,100 |
Net worth = $394,000 − $280,100 = $113,900.
Two things worth noticing in this example. First, the house dominates both sides — $310,000 of asset against $248,000 of mortgage nets to $62,000 of home equity, more than half the total net worth. That’s typical for homeowners and it’s why home-price swings move net worth so much. Second, a negative result is common and not a crisis. A new graduate with $40,000 in student loans and a $6,000 emergency fund sits at roughly −$34,000. The number isn’t a grade; it’s a starting coordinate.
Step 4: Pick a Tracking Method
Calculating once is a snapshot. The value comes from repeating it and watching the direction. Three free ways to do it:
A spreadsheet. One row per account, one column per quarter, a sum at the bottom. Takes 15 minutes to build and 10 minutes to update. Completely private — no bank logins shared with anyone — and you can add whatever charts you like. This is the best option for most people, full stop.
Empower Personal Dashboard. Free, links to your accounts, and updates net worth automatically. Built with an investment slant, so it’s strongest if a lot of your net worth sits in brokerage and retirement accounts.
Monarch Money or Copilot Money. Paid apps that combine budgeting with automatic net-worth tracking. Worth it if you want one tool for everything; overkill if you only want this number.
(If you’re looking for Mint here: it’s gone. Intuit shut it down, and its successor is the money-tracking feature set inside Credit Karma, which can show a basic net worth from linked accounts.)
Whatever you choose, the method matters less than the repetition. A sticky note updated quarterly beats a slick dashboard you never open.
Step 5: Update on a Schedule (and Ignore the Wiggles)
Quarterly is the sweet spot. Monthly updates make market noise feel like progress or failure; annual updates are too slow to catch problems like creeping card balances.
A simple tracking table, continuing the example household above:
| Date | Total assets | Total liabilities | Net worth | Change |
|---|---|---|---|---|
| Jan 1 | $394,000 | $280,100 | $113,900 | — |
| Apr 1 | $399,200 | $277,300 | $121,900 | +$8,000 |
| Jul 1 | $396,800 | $274,600 | $122,200 | +$300 |
| Oct 1 | $405,500 | $271,800 | $133,700 | +$11,500 |
Notice the July row: markets dipped, assets fell, and the quarter looks flat — but liabilities still dropped by $2,700. That’s the reading skill this table teaches. You control the liabilities column directly. The assets column is partly the market’s mood. A flat or down quarter where your debts shrank is a good quarter.
What to Do With the Number
Net worth turns vague intentions into checkable arithmetic:
- Set a direction target, not a magic number. “Increase net worth by $12,000 this year” is actionable: it decomposes into extra debt payments plus savings contributions you can schedule.
- Find the biggest lever. In the worked example, $4,100 of credit card debt at a typical card interest rate is almost certainly the most expensive line on the sheet. The statement makes that visible in a way a monthly budget doesn’t.
- Sanity-check big decisions. New car, home renovation, career break — running the net-worth impact first (“this drops the number by $18,000 and slows the trend for a year”) makes trade-offs concrete.
- Watch the ratio shift. Over years, the goal is for asset growth to come more from investments compounding and less from grinding down debt. The quarterly table shows that transition happening.
Common Mistakes to Avoid
- Counting gross home value but forgetting the mortgage — or the reverse. Always include both sides of any financed asset.
- Using purchase price for cars and gadgets. Resale value only.
- Skipping small debts. Buy-now-pay-later plans and store cards are easy to omit and they add up.
- Comparing yourself to headlines. Median net worth varies enormously by age, housing status, and region. The only comparison that reliably means something is you versus you, last quarter.
- Quitting after one calculation. One data point is trivia. Four data points is a trend, and the trend is the entire product.
The Bottom Line
Block out 30 minutes. List what you own, pull payoff balances for what you owe, subtract, and write the result down with today’s date — spreadsheet, app, or paper. Then put a reminder on your calendar for the first day of next quarter. The first number might sting, but it only ever has to be a starting point. The direction is the part you control.
