Albert Einstein supposedly called compound interest the eighth wonder of the world. Whether he did or not, the math is magical enough to deserve the title.
Here’s how it works. If you put ₹10,000 into an investment earning 10% annually, you don’t just earn ₹1,000 the next year. You earn interest on the original ₹10,000 plus the ₹1,000. Over time, that snowball effect accelerates.
Let’s play it out:
- Year 1: ₹11,000
- Year 5: ~₹16,100
- Year 10: ~₹25,900
- Year 20: ~₹67,300
The lesson? Start early. The biggest advantage you can give yourself is time in the market. Even small, consistent investments add up when compounding does its work. That’s why SIPs (Systematic Investment Plans) in mutual funds or 401(k) contributions in the US are such powerful tools.
What this really means is procrastination is expensive. Every year you delay, you’re not just losing that year’s contribution—you’re losing decades of compounded growth.
