Quick Summary
A practical guide to calculating net worth - what to include, what to skip, common mistakes, and how to turn a one-time calculation into ongoing tracking that actually shows progress.
I remember the first time I calculated my net worth. I was pretty sure I was doing fine - decent salary, some savings, a 401(k) I’d been contributing to for a few years. Then I added up the student loans, the car loan, and the credit card balance I’d been “paying off soon” for eight months.
The number was lower than I expected. A lot lower.
But here’s what I didn’t expect: that mild shock was actually useful. It wasn’t depressing - it was clarifying. For the first time, I could see my entire financial picture in one number instead of a scattered collection of account balances and vague anxiety.
The Formula (It’s Just Subtraction)
Net Worth = What You Own - What You Owe
Assets minus liabilities. That’s genuinely it. Everything else is just figuring out what goes in each column.
Step 1: Add Up What You Own
Start with what’s easy, then work outward.
Bank accounts - checking, savings, money market. Whatever’s there right now.
Investments - brokerage accounts, 401(k), IRA, Roth IRA, HSA (the invested part), 529 plans, crypto if you hold any.
Property - your home (be conservative with the estimate), rental property, vehicles (use Kelley Blue Book private party value, not what a dealer would charge).
Other stuff - but only if you’d actually sell it. Cash value life insurance counts. That $2,000 couch doesn’t. Art or collectibles only if you genuinely know the market value and would realistically sell them.
Here’s a useful test: if you wouldn’t sell it to raise cash in a financial emergency, don’t count it. Your furniture, electronics, and clothes depreciate too fast to mean anything in this calculation.
Step 2: Add Up What You Owe
Everything you owe somebody, somewhere.
Housing - remaining mortgage balance (the current amount, not what you originally borrowed), home equity lines of credit.
Education - student loans, all of them.
Vehicles - auto loans, lease buyout amounts.
Consumer debt - credit card balances (the full amount, not the minimum payment), personal loans, medical debt, buy-now-pay-later balances. Yes, those count too.
Other - tax debt, business loans you’re personally liable for, money owed to family.
One thing people get wrong: use current balances. Your mortgage started at $300,000, but if you owe $267,000 today, that’s the number that matters.
Step 3: Subtract
Here’s an example to make it concrete:
| Assets | |
|---|---|
| Checking + savings | $16,700 |
| 401(k) | $67,300 |
| Roth IRA | $23,100 |
| Home (conservative estimate) | $385,000 |
| Car | $18,500 |
| Total | $510,600 |
| Liabilities | |
|---|---|
| Mortgage | $298,000 |
| Student loans | $34,200 |
| Auto loan | $12,800 |
| Credit cards | $2,100 |
| Total | $347,100 |
Net worth: $163,500
That number by itself tells you something. But calculate it again next month? And the month after? Now you’re tracking a trend - and that’s where the real value lives.
From our experience: When we calculated our net worth after selling Froala, the number looked great on paper - but it was misleading until we separated liquid cash from restricted stock, earnout payments, and tax reserves. That first real calculation taught us that net worth is only useful when you’re honest about what’s actually accessible versus what’s locked up. - Stefan
Mistakes I See All the Time
Inflating the home value. Everyone wants to believe their house is worth more than it is. Use a recent comparable sale in your neighborhood, not the top-end Zillow estimate.
Forgetting debts. That buy-now-pay-later balance from last month, the money you owe your parents, back taxes - they all count. Leaving them out just lies to yourself.
Counting stuff you’d never sell. Your TV is not an asset. Your sneaker collection is probably not an asset either. Be honest about what actually has liquidity.
Obsessing over precision. Round to the nearest hundred. Your net worth fluctuates by thousands every day based on the stock market alone. False precision wastes time.
Why One Number Isn’t Enough
A single calculation tells you where you are. A series of calculations tells you where you’re going.
I started tracking monthly. The first few months felt pointless - the number barely moved. But around month six, patterns started showing up. I could see which accounts were actually growing. I noticed my car was depreciating faster than my loan was shrinking (not great). I saw my emergency fund hitting milestones I’d set.
That monthly rhythm turned a number into a narrative.
The Free Calculator
Our Net Worth Calculator walks through the full calculation with organized categories for everything. It runs in your browser - nothing gets saved or sent anywhere.
For ongoing tracking, the Net Worth Tracker template records your net worth month over month with charts and historical comparisons. One spreadsheet that grows with you.
The number itself is just a starting point. What matters is what the trend looks like a year from now.
