The Federal Reserve's Survey of Consumer Finances tracks American household wealth by age group. The numbers reveal a wide gap between median and mean net worth — because the wealthy skew the average sharply upward. For most people, the median is the more useful comparison.
Federal Reserve Net Worth Data by Age
| Age Group | Median Net Worth | Mean Net Worth | |-----------|-----------------|----------------| | Under 35 | $14,000 | $76,000 | | 35-44 | $76,000 | $437,000 | | 45-54 | $168,000 | $833,000 | | 55-64 | $290,000 | $1,175,000 | | 65-74 | $410,000 | $1,409,000 | | 75+ | $335,000 | $1,217,000 |
Source: Federal Reserve SCF 2022, adjusted for 2026 dollars. Note: the decline after 74 reflects spending down of assets in later retirement.
The gap between median and mean is enormous. A handful of billionaires lifts the mean dramatically. If you're at or above the median for your age group, you're doing better than at least half your peers.
The "Millionaire Next Door" Formula
Thomas Stanley's formula from "The Millionaire Next Door" offers a benchmark for what your net worth should be:
Target net worth = (Age x Annual gross income) / 10
Examples:
- Age 35, earning $80,000: target = (35 x $80,000) / 10 = $280,000
- Age 45, earning $120,000: target = (45 x $120,000) / 10 = $540,000
- Age 55, earning $150,000: target = (55 x $150,000) / 10 = $825,000
Compared to the Fed medians, these targets are aspirational — particularly for younger earners dealing with student debt, high housing costs, and starting salaries. Use them as directional benchmarks, not as reasons to feel like a failure.
What Counts in Net Worth
Included:
- Investment and retirement accounts (401k, IRA, brokerage)
- Home equity (home value minus mortgage)
- Cash, savings, checking
- Other real estate equity
- Business ownership value
- Vehicles (use market value minus any loans)
Not included:
- Social Security future benefits (significant but not a liquid asset)
- Pension values (sometimes included, often excluded from simple calculations)
- Future earnings
A homeowner in their 40s often has significant net worth trapped in home equity — technically countable but not deployable for retirement without selling or a reverse mortgage.
Why People Fall Behind
The most common reasons people underperform benchmarks for their age:
Student loan debt: $100,000+ in graduate school debt in your late 20s starts you negative before you earn a dollar. By 35, the debt is often reduced but hasn't allowed meaningful wealth accumulation.
Late start to investing: Someone who doesn't start investing until 40 misses the highest-impact compounding years. The first $10,000 invested at 25 is worth roughly $45,000 at 55 (7% return). The same $10,000 invested at 40 is worth $19,000.
High cost-of-living areas: Renting in New York or San Francisco absorbs income that would otherwise go to wealth-building. Housing costs aren't net worth when you're renting.
Lifestyle inflation: Income grows but spending grows with it, leaving savings rates unchanged at low percentages.
Catch-Up Strategies by Age Group
Under 35: The single most important action is to start investing now, even small amounts. Max any employer 401k match — that's an immediate 50-100% return. Contribute to a Roth IRA ($7,000/year) while you're in a lower tax bracket. Time is your biggest asset.
35-45: This decade is where income often peaks. Use raises to increase savings rates rather than lifestyle. If you're behind benchmark by $100,000, adding $500/month to investments with 7% returns closes the gap in about 12 years.
45-55: Catch-up contributions kick in at 50 for 401k and IRA. Prioritize eliminating high-interest debt. Evaluate whether your home equity is productively deployed or idle. Some people in this bracket consider downsizing to free up equity.
55-65: Maximize every tax-advantaged account. Consider delaying Social Security to 70 (the benefit increases approximately 8%/year between full retirement age and 70). Reduce high-risk investments while maintaining enough equity exposure to sustain a 25-30 year retirement.
The Savings Rate Is What Actually Matters
Net worth benchmarks are useful but the controllable variable is your savings rate.
| Annual Savings Rate | Years to Reach 25x Annual Expenses (FI) | |--------------------|-----------------------------------------| | 10% | 43 years | | 20% | 37 years | | 30% | 28 years | | 40% | 22 years | | 50% | 17 years | | 65% | 11 years |
The savings rate, not the absolute dollar amount, determines how quickly you build wealth. A nurse earning $75,000 saving 30% reaches financial independence faster than a doctor earning $300,000 saving 10%.
