How to Calculate Your Net Worth in 10 Minutes

TL;DR

List all your assets (bank balances, investments, property, vehicles) at current value. List all your liabilities (mortgage, loans, credit cards) at outstanding balance. Subtract liabilities from assets. That's your net worth. Update it monthly to see the trend.

You know that net worth equals assets minus liabilities. But how do you actually sit down and figure out your number?

Here’s a method that takes about ten minutes. Grab a pen, open your banking apps, and let’s go.

Step 1: List your assets

Go through every account and asset you have. Use current balances, not what you originally paid.

Cash and bank accounts:

  • Checking account balance
  • Savings account balance
  • Any cash on hand

Investments:

  • Stock portfolio at current market value
  • Mutual funds and ETFs
  • Pension or retirement account balance
  • Crypto at current value

Property:

  • Real estate at current estimated market value, not purchase price
  • Vehicle: check a used car site for your model and year

Other:

  • Valuable items you could realistically sell

If you’re unsure about a value, estimate conservatively. A number that’s roughly right is infinitely better than no number at all.

Step 2: List your liabilities

Now list everything you owe.

  • Mortgage balance: the remaining principal, not the original loan
  • Student loans
  • Car loan
  • Credit card balances
  • Personal loans from friends or family
  • Any other debt

Use the current outstanding balance, not the monthly payment. If your mortgage has €180,000 remaining, that’s your liability, regardless of what you pay each month.

Step 3: Do the math

Add up all assets. Add up all liabilities. Subtract.

ItemAmount
Total Assets€_____
Total Liabilities€_____
Net Worth€_____

That’s your number.

If your assets and liabilities sit in more than one currency, the free multi-currency net-worth calculator handles the FX work and gives you a single clean total. It uses live mid-market rates and shows you how each currency contributes to the bottom line, so a strong dollar or weak rupiah does not quietly distort what you actually own.

Common surprises

When people do this exercise for the first time, a few things tend to catch them off guard.

“My car is worth less than I thought.” Cars depreciate fast. That €25,000 car you bought three years ago might be worth €14,000 now. Use current market value.

“My net worth is negative.” If you have a large student loan or mortgage, this is quite common, especially in your twenties and thirties. A negative net worth isn’t failure; it’s a starting point.

“I have more than I realized.” Small accounts add up. That old savings account with €800, the pension your employer contributes to. People often forget these.

The key is consistency

The first calculation is the hardest. After that, it gets easier. Update your number once a month and watch the trend. That trend, whether growing, stable, or shrinking, tells you more than the absolute value ever could.
