How to Calculate Your Net Worth: A 15-Minute Guide

TL;DR — How to calculate net worth: add up everything you own at today's value — cash, accounts, investments, property — then subtract everything you owe: credit cards, loans, the mortgage. What's left is your net worth, the single best scoreboard for your financial life. The first calculation takes about fifteen minutes; after that, updating it once a quarter takes five.

Your net worth is everything you own minus everything you owe — one number that says more about your financial health than your salary ever will. The trouble is that the number lives scattered: a checking balance here, a car loan there, a retirement account you haven't opened in months. Vault — a free budgeting app built to put your whole money picture in one place — exists because most people have never seen that picture assembled.

It turns out almost nobody knows where they stand, and the gap between the headliners and everyone else is wide. According to Empower's 2026 dashboard data, the average net worth of Americans in their 30s is $379,562 — but the median is just $28,578. That 13-to-1 split is what happens when a few big balances pull the average up while the typical household holds far less. The Federal Reserve's Survey of Consumer Finances puts the typical American family's net worth at $192,900. Wherever you land, you can't move a number you've never measured.

What is net worth?

Net worth is the total value of everything you own (your assets) minus everything you owe (your debts). If you sold everything and paid off every debt today, your net worth is the cash you'd have left — or, if it's negative, the debt you'd still be carrying.

It's the one number that ignores appearances. A surgeon with a $400,000 salary, a leased car, and $300,000 of debt can have a lower net worth than a mechanic with a paid-off truck and $40,000 in index funds. Income is a flow; net worth is what the flow has actually built.

How do you calculate your net worth?

Calculate your net worth by listing everything you own at its current value, listing everything you owe at its current balance, and subtracting the debts from the assets. The formula is: assets − liabilities = net worth. A first pass takes fifteen minutes with your account logins and latest statements.

That's it — no software required, no accountant, no algebra. The only judgment calls are what to count and at what value, and both have simple rules, below.

How to calculate your net worth in 4 steps

1. List your assets at today's value. Every account and every thing worth real money: checking, savings, retirement accounts, brokerage, HSAs, cash, your home's current market value, your car's current resale value. Use actual balances, not what you remember.
2. List your debts at today's balance. Credit card balances (not limits), the remaining mortgage, car loans, student loans, personal loans, medical debt, money owed to family. The number you want is what it would cost to pay everything off today.
3. Subtract. Assets minus debts. The result is your net worth — positive, negative, or hovering near zero. All three are normal starting points; the number isn't a verdict, it's a baseline.
4. Date it and repeat quarterly. One calculation tells you where you are. Four a year tell you which direction you're moving and how fast — which is the part that actually changes behavior.

What counts as an asset — and what counts as a debt?

Most confusion about net worth comes from the gray areas. This is the standard split:

Two rules keep the number honest. First, value things at what they'd sell for today, not what you paid — a $35,000 car is a $22,000 asset the moment you drive it home. Second, never net things out in your head: list the house as an asset and the mortgage as a debt, separately, so the table shows both the equity you own and the debt you carry.

Average net worth by age: how do you compare?

Benchmarks are motivating as long as you read the right column. Here are the 2026 figures from Empower's anonymized user data:

Compare yourself to the median, not the average. The average is dragged upward by the wealthiest slice of every age group — it's why a supposedly "typical" 30-something is worth $379,562 while the person in the exact middle of the line holds $28,578. The same pattern shows up nationally: U.S. household net worth reached roughly $174 trillion in early 2026, and most of it belongs to the top slice of households. If you're above the median for your age, you're ahead of more than half your peers. If you're below it, you're in the thick of the pack — and the direction of your number matters more than its rank.

Why your net worth matters more than your income

Income tells you what's flowing in. Net worth tells you what you've kept. The difference is the whole game: plenty of high earners spend the flow and finish a decade of work with nothing to show for it, while modest earners who keep a surplus build real security.

Net worth is also the one scoreboard that responds to every good habit at once. Paying off a credit card raises it. Growing your emergency fund raises it. Every sinking fund you fill for a known future cost — car insurance, holidays, the vet — keeps a debt from forming later, which protects it. If you want a single number to watch instead of a dozen, this is it.

And it's the honest measure of progress when life gets complicated. A raise, a move, a new baby — income and expenses churn constantly, but "is our net worth higher than a year ago?" always has a clean answer.

How to grow your net worth

The math has only three levers: own more, owe less, and let time compound both. In practice, that means:

1. Spend less than you earn, on purpose. A budget isn't a restriction — it's the mechanism that decides in advance how much of your income stays with you. If you've never built one, start with how to start budgeting.
2. Kill high-interest debt first. Every dollar of 20%-APR credit card debt you erase is a guaranteed 20% return — nothing else in finance offers that. The full plan is in how to pay off credit card debt.
3. Automate the surplus into assets. Retirement contributions, a high-yield savings account, index funds — the destination matters less than the automation. Money that never touches checking rarely gets spent; even the classic 50/30/20 rule is just a way to pre-commit that flow.
4. Re-measure quarterly. What gets measured gets managed — and what gets measured quarterly gets managed without obsession.

This is where Vault does the quiet work. Your spending categories live as envelopes, so the surplus in step one is a decision you made on the first of the month, not a hope you check on the last. The reports view shows each month's income against each month's spending — exactly the trend your net worth follows — and because Vault syncs across devices, the numbers you review on a laptop Sunday are the same ones you updated from your phone on Tuesday. Steer the flow in Vault and the stock — your net worth — takes care of its own arithmetic.

Frequently asked questions

What is a good net worth for my age?

A good net worth for your age is anything at or above the median for your age group — about $28,578 in your 30s and $88,851 in your 40s, per 2026 data. A common rule of thumb is one times your annual salary saved by 30, three times by 40, and six by 50. Treat benchmarks as orientation, not judgment: your year-over-year direction matters more than any table.

Does my house count in my net worth?

Yes — list your home's current market value as an asset and the remaining mortgage as a debt, and the difference (your equity) is what actually adds to your net worth. Don't count the full value while ignoring the loan. And be realistic about the price: use recent comparable sales, not the highest listing on your street.

How often should I calculate my net worth?

Quarterly is right for most people — often enough to see the trend, rare enough to ignore market noise. Monthly works if you're actively paying down debt and want the motivation. Weekly is counterproductive, because investment swings will drown out the changes your habits make. Same day, same method, every time.

Why is my net worth negative — and is that bad?

A negative net worth means your debts total more than your assets, and it's common early in adulthood — student loans and a new mortgage routinely outweigh a thin savings account. It isn't a character flaw; it's a starting coordinate. What matters is the slope: if the number climbs every quarter, even from below zero, the plan is working.

The bottom line

How to calculate net worth: total what you own at today's values, total what you owe at today's balances, subtract, and date the result. Fifteen minutes buys you the one number that measures every financial decision you'll make this year — and a quarterly habit turns that number into a trend line you can steer.
