Key Takeaways

  • 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.

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.

Notable Moment

Cramer reveals that Wallace's single first year of investing contributes an equivalent retirement balance to his final fifteen combined years — a ratio that reframes how dramatically early contributions outperform later ones.

This is Optimal Finance Daily. To be young, the best time to invest, by Jesse Kramer of bestinterest.blog. People entering the workforce face a mountain of new financial scenarios and face them in rapid succession. While they might choose to repay loans or buy cool gadgets, they also should consider that their younger years are simply the best time to invest. A real paycheck. I still remember the realization that real money would now be filling up my savings account on a biweekly basis. I had the extra cash to buy all those things I'd always wanted. Sweet. But simultaneously, real bills started showing up. Lame. Student loans, car payments, and monthly rent. And then there were the weekly groceries, my gym membership, gas, and utilities. I had no shortage of options and requirements to spend this new money. You are or were in a similar boat, I bet. A young person's personal finances are stretched thin. And did I mention an emergency fund? Despite all of these expenses, it turns out that your younger years are also the best time to invest in your retirement. I know it's lame. What 22 year old wants to plan for being 60? But I hope that the following math, did this article just get more lame, will convince you. Meet Wallace. First, we have to think about how long a typical career might be. I'm going to assume that our average worker, Wallace, enters the workforce at 22 and retires at 62. That's forty years of solid work. Next, we have to think about Wallace's retirement account and how it grows. Wallace is a simple man. He uses dollar cost averaging to buy S and P 500 index funds. He doesn't need an investment adviser to navigate the market conditions for him, and he doesn't try to time the market. Wallace has a long term time frame. Some years will be great for Wallace. The stock market will boom in a bull market, and Wallace's investments will bloom. Other years will be bad. A bear market means sad …
