How this number is calculated
We look up your age and income in the Federal Reserve's 2022 Survey of Consumer Finances (the most recent SCF, released Sept 2023), then interpolate your position between published 25th/50th/75th/90th/99th percentile breakpoints for that age×income cell. Figures are nominal 2022 USD. Households with similar age and income show meaningful net-worth variance — the percentile reflects how your balance sheet compares to theirs, not to the full US population.
What these numbers mean for age 40, $100k
Two vesting cycles, one home purchase, and a stabilizing career arc define this group. The Fidelity guideline of $300,000 by 40 sits between p50 and p75, which means roughly 35 percent of households here are tracking ahead of it. The defining variable is rarely income — it is the gap between when retirement contributions started and when the household stopped trading down on housing decisions.
Reaching the 90th percentile of $1,000,000 typically requires three converging factors: 401k participation from the first job, a home bought before 2020 in an appreciating metro, and either equity compensation that landed favorably or a working spouse contributing meaningfully. Pure W-2 accumulation at $100k of income can mathematically reach this line, but only with a savings rate sustained near 25 percent for fifteen straight years.
The peak-earning decade (40 to 55) is when this group's balance sheet shifts from "accumulating" to "compounding." A senior engineer with $186,000 invested today, contributing $20,000 annually with a $6,000 match, reaches roughly $850,000 by 55 at 7 percent real returns — a near five-fold expansion. The behavioral question becomes whether peak earnings flow to acceleration, lifestyle expansion, or college funding.

Frequently asked questions
Is buying a vacation or rental property realistic at this median?
For the p75 household with $510,000 net worth, yes — typically through a HELOC on a primary residence or a 25 percent down conventional investment loan. At the median of $186,000, the math usually requires another five to seven years of accumulation or a partner's matching equity.
How much should a 40-year-old here have in 529 plans for two children?
Targeting in-state public tuition (roughly $130,000 for four years by 2040), $30,000 to $40,000 per child by 40 leaves manageable monthly contributions through high school. Households at p75 often have this funded; households at p50 are typically running parallel with retirement instead.
What is a reasonable mortgage payoff timeline at this income?
Most households here hold a 30-year loan from their early thirties, putting payoff between 60 and 63 by default. Recasting or biweekly payment schedules accelerate this five to seven years. Pure prepayment competes against 7 percent equity returns, so the math depends on rate.
When does umbrella liability insurance start to matter?
Around the p75 threshold of $510,000 in attachable assets, a $1 million umbrella policy (typically $200 to $400 annually) becomes meaningful. Trigger events to consider: teen drivers in the household, rental property ownership, or visible-online professions.
How does GS-13 federal employment compare to private-sector peers?
Listed wealth often appears lower than a private-sector senior engineer, but the FERS pension's actuarial value adds $300,000 to $450,000 at 40 with full eligibility ahead. Effective retirement wealth typically pulls federal employees from p50 to roughly p70 once pensions are valued correctly.
Is a backdoor Roth IRA worth the paperwork here?
Single filers begin Roth IRA phaseout at $146,000 (2024) — a single 40-year-old at $100k contributes directly. For married filing jointly with a higher-earning spouse, backdoor mechanics start to matter. The annual $7,000 limit makes the friction worthwhile only for committed savers.
