How to Calculate Net Worth (With Examples)
Last updated
Your net worth is the single best measure of your financial health. Here's the formula, real-world examples at different life stages, and the mistakes that throw most people off.
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.
Total Assets − Total Liabilities = Net Worth
Assets include bank accounts, investments, real estate, and vehicles. Liabilities include mortgages, student loans, auto loans, credit card balances, and any other debts.
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 Different 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 four illustrative examples covering different stages — whether you rent or own. The figures are made up to show the structure, not to serve as benchmarks.
Example 1: Recent Graduate, Age 24
Assets
- Savings account: $5,000
- Used car: $3,000
Total: $8,000
Liabilities
- Student loans: $28,000
Total: $28,000
Net Worth: −$20,000
A negative net worth is completely normal at this stage. The investment in education will likely pay off through higher earning potential over time. If yours is in the red, here's a calm, step-by-step plan for turning a negative net worth around.
Example 2: Renter Building Wealth, Age 33
Assets
- Emergency fund: $12,000
- 401(k) + Roth IRA: $46,000
- Brokerage (index funds): $9,000
- Car (resale value): $8,000
Total: $75,000
Liabilities
- Student loans: $22,000
- Credit card balance: $1,500
Total: $23,500
Net Worth: $51,500
Renting instead of owning doesn't hold this person back. With no mortgage and steady investing, their net worth climbs even while the student debt gets paid down. A rented home never appears on either side of the ledger — only what you own and owe does, as our assets vs liabilities guide explains. Curious how this compares for their age? See net worth by age.
Example 3: Mid-Career Professional, Age 38
Assets
- Retirement accounts (401k + IRA): $50,000
- Home (market value): $280,000
- Savings account: $15,000
- Car: $12,000
Total: $357,000
Liabilities
- Mortgage: $220,000
- Auto loan: $8,000
Total: $228,000
Net Worth: $129,000
Positive and growing. The mortgage is the largest liability, but the home equity and retirement savings more than offset it.
Example 4: Near Retirement, Age 58
Assets
- Retirement accounts: $600,000
- Home (market value): $400,000
- Savings and brokerage: $50,000
Total: $1,050,000
Liabilities
- Remaining mortgage: $80,000
Total: $80,000
Net Worth: $970,000
Decades of saving and debt paydown have compounded. The mortgage is nearly paid off and retirement accounts have grown substantially.
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.
How to Value Tricky Assets
Cash balances are easy — you copy the number straight off your statement. A few assets take more judgment. The rule never changes: use what it would sell for today, and when in doubt, estimate low. Here's how to handle the ones that trip people up.
Your home
Use current market value, not your purchase price or a hopeful asking price. A recent sale of a similar nearby home, or an online estimate as a starting point, gets you close enough. Record the home's value as an asset and the remaining mortgage as a separate liability — never net the two into a single number.
Your car and other vehicles
Use the current private-party resale value from a valuation guide, not the sticker price you paid. Vehicles lose value every year, so this figure should drift downward over time in your snapshots.
A private business or side venture
This is the hardest asset to pin down. Use a conservative estimate of what you could realistically sell your share for, or the cash you'd walk away with after settling its debts — not projected future revenue. When you truly can't tell, leave it out rather than inflate your total.
Investments and crypto
Value stocks, funds, and crypto at their current market price on the day you take the snapshot. These prices move constantly, which is exactly why a monthly snapshot beats checking daily. For what does and doesn't belong on the list at all, see assets vs liabilities.
Once you have your figures, plug them into the free net worth calculator for an instant total, then record it so you can watch the trend. Our guide on how to track your net worth covers building that habit without sharing a bank login.
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. Don't overlook recurring charges either — hidden subscriptions can quietly drain $30–50/month.
- 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.
