How to calculate your net worth, step by step
Net worth is the single best indicator of your financial position: it sums up in one number the result of years of income, spending, debt and investing. The formula is simple — everything you own minus everything you owe — but it's only useful if you value each item with a consistent method and repeat the exercise every month. Doing it properly takes an afternoon the first time and a few minutes after that.
1. The formula, and why it matters more than your salary
Net worth = assets − liabilities. Unlike a salary, which only measures what comes in, net worth also captures what stays. Two people on the same income can end up with opposite net worth depending on how much they spend, how much debt they carry and what returns they earn. That's why it's the number worth tracking if the goal is financial independence rather than income level.
- It's cumulative: it reflects years of decisions, not one month
- It's comparable to itself: the trend matters more than the level
- It's actionable: it rises through saving, market gains or paying down debt
2. List everything you own (assets)
Note the balance of every account, the market value of your investments and a conservative valuation of any relevant property or big-ticket item. Always use the same cut-off date — the last day of the month is easiest — so every line is comparable month to month. For a home, an online estimate or a recent comparable sale is good enough; there's no need for a fresh appraisal every month.
- Bank, savings and cash balances
- Brokerage accounts, funds, ETFs and retirement accounts at market value
- Property and vehicles, valued conservatively and updated occasionally
3. List everything you owe (liabilities)
Use the outstanding principal on each debt, never the sum of the remaining instalments — the instalments include interest that hasn't accrued yet. A mortgage, a car loan and a credit card balance all count the same way: what you'd have to pay today to be debt-free on that item.
4. Subtract, track monthly, and read the trend
Subtract total liabilities from total assets and write the result down with its date. On its own, one figure tells you little; a series of monthly figures tells you whether you're building wealth through saving, through market gains, or through paying down debt — and by how much each contributes.
5. Common mistakes that distort the number
The most common one is counting a mortgaged home as an asset without subtracting the mortgage. Others include valuing a car at its purchase price years later, forgetting a small personal loan, or double-counting money that's already reflected in an account balance.
- Forgetting a liability because there's no monthly statement for it
- Valuing assets at cost instead of at current market value
- Mixing joint and personal net worth without a clear boundary

Frequently asked questions
- How often should I calculate my net worth?
- Monthly is the sweet spot: frequent enough to see the trend, infrequent enough that daily market noise doesn't distract you.
- Should I include my home?
- Yes, at a conservative market value, together with any mortgage attached to it. If you'd rather track finances separately from property, keep two views: one with and one without your home.
- What counts as a good net worth for my age?
- There's no single benchmark that fits every income and location. It's far more useful to track your own trend over time than to compare against a generic rule of thumb.
- Does net worth include a pension or retirement account I can't touch yet?
- You can include it at its current value, ideally in a separate line, since it isn't available for near-term spending the way a savings account is.
