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.

In this lesson

  • How to list your assets at current value, not purchase price
  • How to count debts at their outstanding balance
  • Why updating your number monthly reveals the trend
  • Answers to 5 common questions

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.

Item Amount
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.

Frequently asked questions

How do I calculate my net worth?

List everything you own at its current value: bank balances, investments, pension or retirement accounts, property, and vehicles. List everything you owe at its outstanding balance: mortgage, student loans, car loan, credit cards, and personal loans. Add up the assets, add up the liabilities, and subtract liabilities from assets. The result is your net worth. For property and cars, use current market value rather than purchase price. If you are unsure of a figure, estimate conservatively; a number that is roughly right beats no number at all. The whole exercise takes about ten minutes.

What should I include as assets when calculating net worth?

Include anything you own that has resale or cash value: checking and savings balances, cash on hand, stock and fund portfolios at current market value, pension and retirement account balances, crypto at current value, real estate at its current estimated market value, vehicles priced from a used-car site, and any valuables you could realistically sell. Use current values, not what you paid. Do not include your salary, your degree, or future earnings; those are not assets you own today. Small forgotten accounts, like an old savings account or an employer pension, often add up to more than people expect.

Should I use the loan balance or the monthly payment for liabilities?

Use the current outstanding balance, not the monthly payment. Your liability is the total amount you still owe, regardless of how you repay it. If your mortgage has €180,000 of principal remaining, that €180,000 is the liability, even though you might only pay €900 a month. The monthly payment matters for budgeting and cash flow, but for net worth you need the full remaining balance of every debt: mortgage principal, student loans, car loan, credit card balances, and personal loans.

How do I calculate net worth with assets in different currencies?

Convert every asset and liability into one base currency before subtracting. Pick a functional currency (usually the one you live and spend in), then convert each foreign balance using a recent exchange rate. Add up all assets in that single currency, add up all liabilities, and subtract. The risk is that a strong or weak currency quietly distorts your total. A multi-currency net-worth calculator handles the conversions with live mid-market rates and shows how each currency contributes, so you see one clean total rather than a misleading mix.

How often should I update my net worth calculation?

Update it once a month. The first calculation is the hardest because you are gathering every balance and value for the first time; after that, refreshing the numbers takes only a few minutes. A monthly cadence is frequent enough to reveal the trend without reacting to short-term market noise. Take the snapshot on roughly the same date each month and record it somewhere you can compare over time. Whether the number is growing, stable, or shrinking tells you far more about your finances than any single reading ever could.
