3481: To Be Young! The Best Time to Invest by Jesse Cramer of Best Interest on Long-Term Investing Strategy

What It Covers

Jesse Cramer of Best Interest uses compound interest math to demonstrate why investing during your twenties delivers dramatically outsized retirement returns compared to investing larger amounts later, using a hypothetical worker named Wallace across a 40-year career.

Key Questions Answered

• •Early compounding multiplier: A single dollar invested at age 22 grows 31x by retirement at 62, assuming 9% average annual S&P 500 returns. That same dollar invested at 32 grows only 13x — making each early dollar worth more than twice a later one.
• •The 7-year rule: Wallace's first seven years of investing (ages 22–29) generate half his total retirement balance. The remaining 33 years produce the other half. Prioritizing even modest contributions in your twenties mathematically outweighs decades of larger later contributions.
• •Dollar comparison: Investing $10/year from ages 22–29 ($70 total) produces the same retirement balance as investing $10,000/year from ages 29–62 ($330,000 total) — both reaching approximately $1.9 million. Small early amounts dwarf large late amounts.
• •Starting late still works: For investors who missed their twenties, the same compounding logic applies from wherever you are now. Ages 40–46 carry the same growth weight as ages 46–62, so beginning immediately at any age still captures meaningful compounding advantage.
