The one true number
Net worth is the only financial number that captures everything about your wealth in one place: assets minus liabilities. Income is a cash-flow story. Salary is a compensation story. Net worth is the balance-sheet truth. A surgeon making $400K with $600K in student loans, a leased Tesla, and $8K in savings has a negative net worth. A teacher making $55K who has lived in the same paid-off house for 30 years may have more.
The categories that matter
Assets: cash, taxable brokerage, retirement accounts (401k, IRA, Roth), real estate at fair market value, vehicles at Kelley Blue Book private-party value (not what you think it's worth — what you could actually sell it for this week). Optional: jewelry, collectibles, business equity, if you can value them objectively.
Liabilities: mortgage principal remaining, home equity loans, auto loan balances, student loans, credit card balances, personal loans, medical debt, tax debt, unpaid balances on buy-now-pay-later services. All of it. If it generates a payment or could be collected against you, it counts.
Liquid vs total net worth
Two numbers to watch. Total net worth includes home equity and retirement accounts — real wealth, but hard to access without major tax or life consequences. Liquid net worth is what you could actually turn into cash in 30 days: savings, taxable investments, minus consumer debt. This is the number that matters in an emergency, and many house-rich-cash-poor Americans are shocked when they calculate it.
What "good" looks like at each age
A loose framework from personal finance literature: by age 30, you should target a net worth equal to half your annual income. By 40, equal to your annual income. By 50, two to three times. By 60, five to eight times. These are rough targets — an aggressive saver or a late starter will look very different — but they give you a way to ask "am I on pace?" The calculator above gives you today's honest number; compare it to the age target.
Why debt-aware matters
The cliché "I have $500K in real estate" or "I have a $50K car" ignores the other side of the balance sheet. A home with $200K of equity and $200K of mortgage debt contributes $200K to net worth, not $400K. A $50K car loan equals $50K of negative net worth plus a depreciating asset (the car, typically worth less than the loan in early years). The calculator above treats both sides honestly.
How to grow it fastest
Net worth grows from both ends. Adding assets (saving, investing, building equity) and reducing liabilities (paying off debt) each add to the bottom line. For most people with consumer debt at rates above 10%, paying debt has a higher guaranteed return than most investments — making it the highest-leverage net-worth move available.

Track it quarterly
Net worth is a slow-moving number. Checking daily is a fast way to make yourself anxious for no reason — markets move, home estimates bounce, and none of it matters at that timescale. Quarterly is the sweet spot: often enough to notice trends, rarely enough to ignore noise. Most millionaires track net worth once a quarter. It's the only financial ritual some of them maintain.
