Most people think about financial health in terms of salary. It makes sense — income is visible, easy to compare, and shows up on a regular schedule. But income tells you how fast water flows into the bucket. Net worth tells you how much is actually in the bucket. I've seen households earning $250,000 with $400,000 in debt and nothing saved — net worth near zero. And households earning $65,000 with a paid-off home and $200,000 in retirement accounts — net worth over $400,000. The second family is wealthier by every metric that actually matters.
Here's how to calculate yours properly, what to count and what to skip, how you stack up against real benchmarks, and why this one number tells you more about your finances than your paycheck ever will.
Dead simple: Net Worth = Total Assets − Total Liabilities. Assets are everything you own with monetary value. Liabilities are everything you owe. The difference is your net worth, and yes, it can be negative.
The math is easy. The hard part is being honest about what goes on each side.
Assets break into two buckets: liquid (things you can convert to cash fast) and illiquid (things worth real money that take time to sell).
What NOT to include: Furniture, clothing, electronics, and jewelry (unless we're talking genuinely valuable pieces like fine art or collectibles). These things depreciate fast and are nearly impossible to sell at meaningful prices. I've seen people list $15,000 in "household goods" on their net worth worksheet — that's not wealth, that's stuff. A conservative number is always more useful than a feel-good one.
Include every debt you owe — to a lender, institution, or individual. Use the current outstanding balance, not the original loan amount.
Let's run through a realistic example. Sarah, 34, earning $82,000/year:
| Assets | Value |
|---|---|
| Checking & savings accounts | $18,500 |
| 401(k) balance | $67,200 |
| Roth IRA | $22,400 |
| HSA | $4,800 |
| Home (estimated market value) | $345,000 |
| Car (2021 Honda Civic, KBB value) | $18,900 |
| Total Assets | $476,800 |
| Liabilities | Balance |
|---|---|
| Mortgage (remaining principal) | $278,000 |
| Student loans | $14,200 |
| Auto loan | $8,600 |
| Credit card balance | $1,900 |
| Total Liabilities | $302,700 |
Sarah's net worth: $476,800 − $302,700 = $174,100
At 34, Sarah's $174,100 puts her above the median for her age group ($135,600 for ages 35–44 per the Federal Reserve's Survey of Consumer Finances). Her biggest asset is home equity ($67,000), followed by retirement savings ($89,600 combined). The auto loan and student debt are manageable and declining. She's in solid shape — but the number matters less than the trajectory. Is it growing quarter over quarter? That's the real question.
The Federal Reserve's Survey of Consumer Finances, conducted every three years, is the gold standard for net worth data. The most recent survey (2022, published 2023) shows:
| Age Group | Median Net Worth | Average Net Worth |
|---|---|---|
| Under 35 | $39,000 | $183,500 |
| 35–44 | $135,600 | $549,600 |
| 45–54 | $247,200 | $975,800 |
| 55–64 | $364,500 | $1,566,900 |
| 65–74 | $409,900 | $1,794,600 |
| 75+ | $335,600 | $1,624,100 |
Source: Federal Reserve Survey of Consumer Finances (2022). Median is the midpoint — half of households are above, half below. Average is pulled dramatically higher by extremely wealthy households.
Look at the gap between median and average. In the 55–64 group, the average ($1.57M) is more than four times the median ($364,500). A handful of very wealthy households drag the average way up while the median doesn't budge. For comparing yourself to "normal," the median is the number that matters — it tells you where the typical household actually stands.
A useful rule of thumb (from Fidelity): 1x your salary saved by 30, 3x by 40, 6x by 50, 8x by 60, 10x by 67. It's a rough framework, not a pass/fail test — but it gives you a goalpost that scales with your income. The Wealth Percentile Calculator can show you exactly where you land relative to your age group.
Income measures earning power. Net worth measures accumulated wealth. That distinction matters because income can vanish overnight. A layoff, a disability, an economic downturn — any of these can drop your income to zero. Net worth is what carries you through.
Consider two households:
| Household A | Household B | |
|---|---|---|
| Annual income | $210,000 | $78,000 |
| Monthly spending | $14,500 | $4,200 |
| Net worth | $45,000 | $320,000 |
| Months of runway if income stops | 3.1 months | 76 months |
Household A earns nearly three times more but has just 3 months of runway. Household B could go over six years without income. That's the difference between income and wealth. Your savings rate and accumulated assets are what create real financial resilience — not the number on your paycheck.
This is also why debt-to-income ratio, while useful for mortgage qualification, doesn't tell the full story. A high earner with high debt and no savings can have a great DTI but fragile finances. I'd recommend tracking your debt-to-income ratio alongside net worth for the complete picture.
This is the variable you control most directly. Someone saving 20% of $70,000 accumulates wealth faster than someone saving 5% of $150,000. Do the math: $14,000/year vs $7,500. Salary doesn't determine wealth — savings rate does. The Budget Calculator can show you where your money actually goes and what your real savings rate looks like.
Once you have savings, investment returns become the multiplier. Over 30 years, the difference between 4% (savings account) and 7% (stock market average after inflation) on $14,000/year in contributions is massive: roughly $810,000 vs $1,420,000. Same contributions, $610,000 difference — that's the power of rate plus time. Model your own numbers with the Compound Interest Calculator.
Every dollar of principal you pay down increases your net worth by exactly one dollar. That's why mortgage payments, while painful, are partly wealth-building — the principal portion converts liability into equity with each payment. High-interest consumer debt is different. It's an active drag on net worth because interest payments create zero assets and eat into your ability to save.
For most American households, home equity is the single biggest piece of net worth. That's partly by design (forced savings through mortgage payments) and partly appreciation. U.S. home prices have historically appreciated about 3.5–4% annually, roughly matching inflation. Home equity is real wealth, but it shouldn't be your only wealth — it's illiquid, undiversified, and concentrated in one asset.
Higher income doesn't automatically boost net worth — lifestyle inflation can swallow every raise whole. But if you hold your savings rate steady while income goes up, the effect compounds beautifully. A 10% raise with a constant 20% savings rate means 10% more dollars flowing into investments every year.
Overvaluing your home. People tend to use Zillow's highest estimate, peak neighborhood prices, or the nicest comp on the block. Don't. Ask yourself: if I had to sell in 60 days, what would it realistically fetch? That's your number.
Ignoring taxes on retirement accounts. A $500,000 Traditional 401(k) is not $500,000 in spending power. You'll owe income tax on every dollar you withdraw. Some planners discount Traditional balances by 15–25% to account for the embedded tax bill. Roth accounts, on the other hand, are worth face value since withdrawals are tax-free. That distinction matters more than most people realize when comparing to benchmarks.
Counting personal property. Your couch, your wardrobe, your kitchen appliances — none of that is a meaningful asset. It depreciates fast and can't be converted to cash at useful values. Listing it just inflates your number without adding anything to your financial resilience.
Forgetting small debts. That $2,400 medical bill, the $800 you owe a friend, the $3,200 in Buy Now Pay Later balances — they add up. Go through every account and obligation when tallying your liabilities.
Checking too often. Tracking daily leads to anxiety over stock market fluctuations that are pure noise over long time horizons. Quarterly is the right cadence for most people. More than that and you're just watching the market twitch.
If I could recommend one financial habit, it's this: track your net worth quarterly. Takes about 15 minutes:
Over a few years, this builds a trend line that reveals patterns you'd never see in monthly bank statements. The impact of raises, bonuses, market moves, big purchases, and debt paydown all show up clearly. And there's a built-in accountability effect — it's hard to ignore a declining trend when you're staring at it every 90 days.
Negative net worth is completely normal here, especially with student loans. The priorities: build an emergency fund (3–6 months of expenses), start retirement contributions (especially if there's an employer match), and attack high-interest debt. Even small progress matters. Going from −$35,000 to −$20,000 is a win worth recognizing.
Earnings tend to climb, and compound growth starts showing up noticeably in retirement accounts. A lot of people buy homes in this decade, which creates a big asset and a big liability at the same time. The key: don't let your savings rate erode as lifestyle costs creep up with homeownership, kids, and career expenses.
This is where compounding gets exciting. Retirement accounts that received steady contributions for 15–20 years start showing real momentum. Someone who put $6,000/year into a Roth IRA from 25 has contributed $90,000 by 40 — but the account is probably at $130,000–$160,000. The portfolio is now generating returns that outpace what you're putting in. That's the inflection point.
Income usually peaks here. Catch-up contribution limits kick in ($7,500 extra for 401(k), $1,000 extra for IRA as of 2026), and kids may be leaving the house, freeing up significant cash flow. This is the decade where aggressive saving pays the biggest returns — your money still has 10–15 years to compound before you start pulling from it.
Net worth usually peaks in the mid-60s and then gradually declines as you start drawing down. That's not failure — that's the plan working. The whole point of building net worth was to eventually spend it. The only question is whether the decline rate is sustainable across your expected lifespan. The Retirement Calculator can help you model different withdrawal scenarios.
