Net worth percentiles by age come from official statistical surveys: the US Federal Reserve Survey of Consumer Finances (every 3 years), the UK ONS Wealth and Assets Survey (biennial), and SARB Quarterly Bulletin household balance sheet data. Median US household net worth in the 2022 SCF was $192,700.

Comparing yourself to a net worth percentile by age is a useful sanity check on whether your financial plan is on, ahead, or behind a benchmark trajectory — but it's a check, not a goal. The number is shaped by country, cohort effects (housing booms, recessions during career-formative years), inheritance, and life circumstances no benchmark can encode. The calculator helps you position yourself accurately against the right peer group.

Data sources used:

• US: Federal Reserve Survey of Consumer Finances (SCF), conducted every 3 years; the 2022 SCF is the most recent release with the 2025 round in field. The SCF is the gold standard for US wealth data, with both summary tables and microdata published.
• UK: ONS Wealth and Assets Survey, conducted every 2 years; latest round covers April 2020 - March 2022. Tables 2.1, 2.5, and 4.1 provide net worth by age band.
• South Africa: SARB Quarterly Bulletin household balance sheet, with composition (financial vs property) reported quarterly.
• Australia: ABS Survey of Income and Housing (biennial).
• Canada: Statistics Canada Survey of Financial Security (every 4-5 years).

Typical US net worth percentile cuts (2022 SCF, ages 35-44): - 10th percentile: ~$0 or negative - 25th percentile: $15,000 - Median (50th): $135,300 - 75th percentile: $400,000 - 90th percentile: $1,300,000+ - 99th percentile: $8,000,000+

Typical UK net worth percentile cuts (WAS 2020-22, ages 35-44): - Median: ~£170,000 (heavily weighted by housing equity) - 75th percentile: ~£440,000 - 90th percentile: ~£900,000

The calculator inputs your assets (property, investments, pensions, cash, vehicles) and subtracts liabilities (mortgage, student loans, credit card, auto loan) to compute net worth, then plots you against the relevant age cohort distribution for your country.

A useful framing: net worth percentile is a lagging indicator. Savings rate (savings ÷ gross income) and asset allocation are the leading indicators. If your savings rate is in the top quartile for your age cohort today, your net-worth percentile will move accordingly over a 10-year window.
