How to Calculate Net Worth (With Examples)

The Net Worth Formula

Calculating your net worth takes one simple equation. Add up everything you own, subtract everything you owe, and the result is your net worth. That's it. There's no weighting, no scoring algorithm, no credit bureau involved. Just a straightforward subtraction.

If you're not sure what counts as an asset or a liability, our assets vs liabilities guide breaks it down in detail. For now, the important thing is to be thorough and honest. Include retirement accounts even if you can't touch them yet. Include that car loan even if the payments feel routine. Everything goes on the list.

The number you get might be positive, negative, or right around zero. All three are valid starting points. What matters is that you have a number — because you can't improve what you don't measure.

Worked Examples at Three Life Stages

Net worth looks completely different depending on where you are in life. A negative number in your twenties can be perfectly healthy. A six-figure net worth in your fifties might feel behind if you're planning to retire soon. Context matters. Here are three realistic examples to show how the formula plays out at different stages.

Notice the pattern: net worth tends to start negative, cross zero in your late twenties or thirties, and accelerate from there as debts shrink and investments compound. If you want to see how your number compares to national averages, our net worth by age guide has detailed benchmarks.

Common Mistakes to Avoid

The formula itself is simple, but people trip up on the inputs. Here are the five most common errors that lead to an inaccurate net worth calculation.

• 1.

  Overvaluing your car

  Your car is not worth what you paid for it. Look up the current resale value on a site like Kelley Blue Book and use the private-party or trade-in price, not the dealer retail price. Vehicles depreciate fast — a three-year-old car may be worth 40–50% less than what you paid.

• 2.

  Forgetting small debts

  A $2,000 personal loan from a family member, a $500 medical bill on a payment plan, or a buy-now-pay-later balance all count as liabilities. Small debts add up and leaving them out paints a rosier picture than reality.

• 3.

  Counting future income

  Your upcoming bonus, an expected inheritance, or Social Security benefits you'll receive in 20 years are not assets yet. Only include money and property you have right now. Net worth is a snapshot of today, not a forecast.

• 4.

  Ignoring retirement accounts

  Some people leave out their 401(k) or IRA because they can't access the money until age 59½. But those accounts absolutely count. They're your money — just on a time delay. Excluding them can make you feel worse off than you actually are.

• 5.

  Obsessing over daily changes

  Your net worth will fluctuate day to day as the stock market moves and balances shift. Checking daily leads to anxiety, not insight. A monthly or quarterly update gives you a much clearer picture of your actual trajectory. Focus on the trend, not the noise.

When to Use a Calculator vs an App

If you just want to know your net worth right now, a simple calculator is all you need. Our free net worth calculator lets you plug in your numbers and see the result in under two minutes. No sign-up required, nothing stored anywhere.

But a single calculation only tells you where you are today. The real value comes from tracking over time — seeing how your net worth changes month to month, spotting which categories grow fastest, and recognizing when you hit meaningful milestones.

That's where a dedicated app shines. CustomWorth stores your data privately on your device, lets you categorize assets and liabilities, and shows your progress over time with clean charts. If you're serious about building wealth — not just measuring it once — an app turns the calculation into a habit. Check our guide to tracking your net worth for tips on getting started.
