The Magic of Compound Interest: Why Starting Early Matters

Albert Einstein allegedly called compound interest "the eighth wonder of the world." Whether he said it or not, the sentiment is absolutely true-compound interest is the most powerful force in wealth building.

What is Compound Interest?

Imagine sitting at your kitchen table, a mug of coffee cooling beside you, as you wonder, “When should I start investing?” The answer lies in a little force that quietly builds fortunes over decades-compound interest. Compound interest is earning interest on your interest. Instead of just earning returns on your original investment, you earn returns on your original investment PLUS all the returns you've earned in previous years.

Imagine this

Long ago, a young woman named Sarah decided at age 25 to pay herself first. She set up an automatic transfer: $200 a month, tucked away into an investment account. Life was busy, work was demanding, but she never skipped a month. She watched her savings grow slowly at first-so slowly, at times, it seemed barely worth it. But over the years, something magical began to happen: her money started earning money, and then the returns themselves started earning returns. That’s the very heart of compound interest.

Meanwhile, Mike, a friend of Sarah’s, spent his 20s traveling and paying down debts. By age 35, the importance of investing clicked for him. He started his own $200/month plan. But even though Mike saved for three times as long as Sarah, compounding could never fully catch up: by age 65, Sarah’s stash had snowballed to $688,000, while Mike’s, even after 30 years, fell short at $609,000. Sarah put in less money but ended with more - simply by starting early.

That’s the secret: time is the greatest multiplier. Compound interest doesn’t care how old you are, only how long you give it to work.
