Why a boring 8% is a spectacular return
Sam recounts a prior episode where he offered Shaan a hypothetical: invest only in your own business plus one vehicle returning a guaranteed 8% a year, nothing else. Shaan refused outright; Sam and Ramit both consider it an extraordinary deal. Ramit works the rule of 72 live — divide 72 by your return rate, so at roughly 10% nominal your money doubles every seven to ten years. His key correction is that people evaluate compounding as a one-off deposit when the real mechanic is continuous contribution, which he likens to pushing a train that eventually cannot be stopped.
- Rule of 72: 72 divided by return rate equals years to double
- At roughly 10% nominal, money doubles every 7-10 years
- Average returns of 7-8% are phenomenal if you understand time
- The compounding mistake is imagining a single deposit, not repeated contributions
- Sam has never sold a stock in his life and holds HubSpot, Airbnb and index funds
