Sethi's distilled wealth formula, illustrated by Warren Buffett making over 99% of his wealth after age 60: you don't need genius or stock-picking. Start as early as possible, invest aggressively every single month, and keep your costs low. The human mind isn't built for compounding, so plug real numbers into a calculator to see it — modest monthly amounts become millions over decades at a conservative 7%.
Origin
Sethi cites Morgan Housel's analysis of Buffett and runs a live compound-interest calculation with Bartlett, from $5k/year at 16 to over $12M by 65.
Core principles
- 01Wealth comes from small wins over time, not big risks (83% of millionaires agree).
- 02Buffett made over 99% of his wealth after 60 — time in the market is everything.
- 03Use a conservative 7% real return; don't chase juiced returns.
- 04The mind can't intuit compounding — run it through a calculator to believe it.
How to run it
- 1
Start now
Begin as early as possible; if you're 30, 40, or 45, start today rather than waiting.
- 2
Invest aggressively every month
Contribute consistently and ratchet up the amount as your income grows.
Pro tip Income rises in your 30s and 40s — nudge the automatic amount up a few hundred dollars.
- 3
Keep costs low
Minimise fees; 1% takes 28% of returns, 2% takes over 55%.
Pro tip Assume 7% to avoid downside surprises; if you get 8%, it's a bonus.
Watch out Don't chase 13% PE funds or 'juiced' returns — you'll lose money.
In the wild
Investing $5k/year from 16 at 7% yields ~$133k by 30, ~$736k by 50; ratcheting to a $30k/year average yields over $12M by 65.
→ Modest, consistent contributions plus time produce life-changing sums.
Buffett started investing very young and made over 99% of his wealth after age 60 through decades of compounding.
→ The lesson: no fancy strategy needed, just early start and patience.
Common mistakes
Chasing get-rich-quick returns
Wanting 10,000% returns (crypto, hot tips) is the money equivalent of six-pack abs in 10 minutes — it usually ends in loss.
Is it for you?
Best for
Anyone building long-term wealth on an ordinary income.
Not ideal for
Those needing liquidity in the short term who can't leave money to compound.
