While the exact percentage varies by study, research consistently shows that a large majority—typically between 75% and 88%—of millionaires are "self-made," meaning they did not inherit their wealth, rather than the 90% figure often cited.

U.S. Wealth Distribution is Top Heavy
The rich half own about $156 trillion (or about 98% of it). The poorer half only own about $4 trillion. Breaking down that top half even further, the top 1% (1.3 million families) owns about $49 trillion (or about one-third of the total share) by themselves.
Only a small fraction of Americans, around 1.8% of U.S. households, have $2 million or more saved in retirement accounts, according to analyses of Federal Reserve data by organizations like the Employee Benefit Research Institute (EBRI).

The 3-6-9 rule in finance is a guideline for building an emergency fund, suggesting you save 3 months of essential expenses for stable jobs, 6 months for most people (especially those with families/mortgages), and 9 months for those with irregular income (freelancers, sole earners) or high financial risk.

The 7-3-2 rule is a financial strategy for wealth building, suggesting it takes 7 years to save your first major financial goal (like a crore), then accelerating to achieve the next goal in 3 years, and the third goal in just 2 years, leveraging compounding and disciplined, increased investments (like a 10% annual SIP hike). It highlights how returns compound faster over time, drastically reducing the time needed for subsequent wealth targets, emphasizing patience and consistent, growing contributions.
The "7-year inheritance rule" (primarily a UK concept) means gifts you give away become exempt from Inheritance Tax (IHT) if you live for seven years or more after making the gift; if you die within that time, the gift may be taxed, often with a reduced rate (taper relief) applied if you die between years 3 and 7, but at the full 40% if you die within 3 years, helping people reduce their estate's taxable value by giving assets away earlier.
