The Wealth Gap Visualizer shows where your income and net worth fall on national and global percentile distributions, plus contextual benchmarks: how you compare to median household, years to top 1% at current growth, and the spread between income and wealth percentiles (often dramatically different). Uses Federal Reserve Survey of Consumer Finances (SCF) data — the gold-standard triennial survey of US household balance sheets, last updated in October 2023 with 2022 data. Key US benchmarks (2022 data, expressed in 2022 dollars): Median household income $74,580. Top 10% income threshold ~$216,000. Top 1% income ~$650,000. Median household net worth $192,700 — but mean is $1.06M, showing extreme skew. Top 10% net worth threshold ~$1.94M. Top 1% net worth ~$11.1M. Top 0.1% net worth $46M+. Bottom 50% combined own roughly 2.5% of total US wealth; top 1% own 30%+. Income and wealth percentiles differ dramatically for most households. A 35-year-old physician earning $400k may sit at the 96th income percentile but only the 60th wealth percentile (high salary, recent student loan payoff, mortgage). A 70-year-old retired teacher with paid-off house and pension may be at the 40th income percentile but 80th wealth percentile. Wealth requires both high savings rate and time for compounding — income alone doesn't determine wealth. Global perspective adds humility: World Inequality Database reports global median income (PPP-adjusted) is around $7,000 USD. A US household at the 50th percentile ($74k) sits at the global 95th percentile. Median US net worth ($192k) is global top 1–2%. These framings can help reframe American sense of financial scarcity — many feeling 'middle class' globally are upper-class. Calculator presents both national and global views to contextualize relative position.
- 1Step 1 — Enter annual household income (use gross — pre-tax)
- 2Step 2 — Enter net worth (total assets − total liabilities)
- 3Step 3 — Select country or 'Global' for international perspective
- 4Step 4 — Calculator looks up percentile in Federal Reserve SCF distribution
- 5Step 5 — Outputs income percentile, wealth percentile, vs median household
- 6Step 6 — Computes years to top 1% threshold at typical wealth growth rate
- 7Step 7 — Compares income vs wealth percentile (often very different — informative)
High earner but middle wealth — typical pattern for career-stage 30s/40s with mortgage and family expenses.
Common retirement profile — pension/Social Security plus accumulated home equity and 401k
Wealth percentile far exceeds income — the goal of lifetime saving and compound growth.
Big paycheck but recent grad — student loans and starter savings dominate. Wealth percentile will catch up over decades if savings rate is high.
US median household is global top 5%. Important framing for relative perspective.
Financial context and reality check

Global perspective on US affordability
Why are wealth percentiles so different from income?
Wealth compounds — top wealth tiers reflect inheritance, equity, business ownership, and decades of compounding. Many high earners ($150k+) have modest wealth if they spend most of what they make (lifestyle inflation). Top wealth percentiles are heavily skewed toward older households (60+) who have had time to accumulate. Income predicts wealth poorly without savings rate and time.
Should I focus on income or wealth percentile?
Net worth percentile is the better predictor of financial security and life options. High income with low net worth means you're one job loss from crisis. Modest income with high net worth (paid-off house, retirement savings, low debt) is robust. Long-term goal: shift from income-percentile rank to wealth-percentile rank by saving aggressively in high-earning years.
How does the calculator handle home equity?
Include home equity (current market value minus mortgage) in net worth. SCF data includes primary residence equity, so percentile rankings are consistent. Some financial calculators exclude home equity for 'liquid net worth' which is more conservative — your calculator output for that would be lower percentile.
Is the top 1% really that wealthy?
Yes — top 1% threshold is $11M+ net worth (US, 2022 SCF). Top 0.1% is $46M+. Top 0.01% (3,500 households) is hundreds of millions. The distribution is extremely skewed because wealth compounds and concentrates over time. Median household ($192k) and top 1% ($11M+) differ by 57×.
How does global compare to US?
US median ($74k income, $192k net worth) is approximately global 95th percentile. World median income (PPP-adjusted) is ~$7k; world median net worth is ~$8k. Most Americans who feel 'middle class' are globally upper-class. Useful framing for relative perspective without dismissing real domestic affordability challenges.
เคล็ดลับโปร
Focus on net worth percentile, not income — wealth predicts financial security far better than annual earnings. A high-income household with no savings is one layoff from crisis; a moderate-income household with paid-off home and retirement accounts is robust. Shift focus from raise hunting to savings rate over your career.
