The formula
The math behind net worth is genuinely simple. There are no rates, no compounding, no projections — just one subtraction:
Net worth = total assets − total liabilities
Assets are things you own that have value. Liabilities are debts you owe. The gap between them is your net worth — and yes, it can be negative, which is common early in a career or right after buying a home. What matters far more than today's number is the direction it moves over time.

Step 1 — List your assets
Start with everything you own that has real, sellable value, priced at what it is worth today — not what you paid for it. Go category by category so nothing slips through:
- Cash and bank accounts — checking, savings, money market accounts, and any physical cash worth counting.
- Investments — brokerage accounts, stocks, ETFs, bonds, and mutual funds at their current market value.
- Retirement accounts — 401(k), IRA, pension fund balances. These are the most commonly forgotten asset, and often the largest.
- Real estate — your home and any other property at a realistic current market price, not the purchase price.
- Vehicles — cars and motorcycles at resale value. Check a used-market listing rather than guessing.
- Crypto and gold — coins, tokens, and physical metal at today's spot or exchange price.
- Valuables — jewelry, art, collectibles, but only items you could genuinely sell for a meaningful amount.
Skip everyday possessions like furniture and electronics. Their resale value is small, hard to estimate, and mostly adds noise to a number you want to trust.
Step 2 — List your liabilities
Now write down everything you owe, using the current payoff balance of each debt — the amount you would need to hand over today to be free of it, not the original loan amount and not the monthly payment:
- Mortgage — the remaining balance on your home loan, from your latest statement.
- Credit cards — the full outstanding balance on every card, even the ones you pay off monthly.
- Student and car loans — remaining principal on each.
- Money owed to people — personal loans from family or friends, buy now pay later plans, and anything else you are on the hook for.
Be complete here. A forgotten $2,000 card balance distorts your number just as much as a forgotten $2,000 account — and small debts are exactly the ones that hide.
Step 3 — Subtract
Total each column and subtract. Here's a complete worked example for someone with a home, a couple of loans, and a mix of savings and investments:
Assets
Liabilities
That's it. Notice how the picture only makes sense with both sides: the $160,000 home looks impressive alone, but it comes with a $98,000 mortgage. Net worth forces every asset to face the debt attached to it.
What if your money lives in several currencies?
If you hold a salary account in one currency, investments in another, and maybe some crypto priced in dollars, you can't just add the raw numbers — 10,000 euros and 10,000 pesos are wildly different amounts. The fix is to pick one display currency (usually the one you think in) and convert every balance into it at the current exchange rate before adding.
Do the conversion at today's rate every time you recalculate, not the rate from when you opened the account. Exchange rates move, and a real part of your net worth change each month comes from FX, not just saving or spending. This is tedious to maintain in a spreadsheet — which is why Guaca keeps every account in its native currency and converts everything to your display currency automatically, using daily rates. You see one number, and you can switch the display currency with one tap.
How often should you recalculate?
Monthly is the sweet spot for most people. It's frequent enough to catch problems — creeping card balances, an account you stopped funding — and infrequent enough that market noise doesn't dominate. Checking daily mostly measures your mood against the stock market; checking yearly leaves too long between course corrections.
Whatever cadence you pick, record each result. A single net worth figure is a snapshot; a series of them is a trend, and the trend is the real payoff. Twelve monthly data points tell you whether your saving rate outruns your spending, how much of your growth came from contributions versus market gains, and whether a big purchase actually dented your trajectory. A notebook or spreadsheet works; an app like Guaca does it automatically, keeping a history you can scrub through to see exactly what moved your number — the market, the exchange rate, or your own deposits.
Common mistakes to avoid
Forgetting pension and retirement accounts
Because you can't spend it yet, retirement money feels invisible — but for many people it's the single largest asset they own. Leaving out a 401(k) or pension fund can understate your net worth by six figures and make years of disciplined saving look like stagnation.
Using purchase price instead of market value
The car you bought for $28,000 five years ago is not a $28,000 asset today, and the home you bought a decade ago is probably worth more than you paid. Net worth is a snapshot of the present, so every asset should carry the price it would fetch now. Check recent sales for property and used-market listings for vehicles.
Ignoring small debts
A $900 card balance, a buy-now-pay-later plan, $500 owed to a friend — each feels too small to bother with, but together they add up, and skipping them builds a habit of flattering the number. Count every debt, however minor. A net worth figure you've quietly rounded in your favor can't do its job.
Frequently asked questions
Should I include home equity in my net worth?
Yes, but count both sides. List your home at its current market value under assets and the remaining mortgage balance under liabilities. The difference between the two is your home equity, and it flows into your net worth automatically when you subtract. Don't list only the equity as an asset — that makes it easy to double-count or lose track of the loan.
Is net worth calculated on gross or net values?
Use current market values for assets and current payoff balances for debts — not your gross income, and not what you originally paid. Income doesn't appear in the formula at all: net worth is a snapshot of what you own minus what you owe on a given day. A high earner with big loans can have a lower net worth than a modest earner who has saved consistently.
Do I include my partner's assets and debts?
It depends on what you want the number to tell you. For household planning, combine everything you and your partner own and owe into one household net worth. For personal tracking, count only what is in your name plus your share of joint accounts and jointly owned property. Pick one convention and stick with it, otherwise your trend line becomes meaningless.
What about pensions and retirement accounts?
Defined-contribution accounts like a 401(k), IRA, or private pension fund have a statement balance — include that full balance as an asset, even if you can't touch it yet. Defined-benefit pensions that pay a monthly income in retirement are harder to price; many people leave them out and treat them as future income instead. Either way, be consistent from one calculation to the next.
Is net worth the same as wealth?
Net worth is the standard way to measure wealth in numbers, but it isn't the whole picture. It ignores your earning power, the stability of your income, and things that matter but don't have a price. Still, as a single trackable figure, net worth is the best proxy we have: if it rises steadily over the years, you are building wealth.
