The Magic of Compound Interest

Albert Einstein reportedly called compound interest the "eighth wonder of the world." Unlike simple interest, where you only earn returns on your principal, compounding means you earn returns on your returns. Over long periods (10+ years), the interest you earn can actually exceed the amount of money you originally invested.

How is it calculated?

This calculator uses the Future Value formula, assuming monthly compounding for better accuracy with monthly contributions (SIPs).

Formula (simplified):
A = P × (1 + r)^n
Where P is Principal, r is rate, n is time.

Why start early?

Consider two investors:

  • Person A: Invests $500/mo from age 25 to 35, then stops.
  • Person B: Starts at 35 and invests $500/mo until 60.
  • Surprisingly, Person A often ends up with more money at retirement due to the extra 10 years of compounding!

Frequently Asked Questions

What is SIP?
SIP stands for Systematic Investment Plan. It allows you to invest small amounts of money periodically (monthly/quarterly) into mutual funds or other assets, averaging out the cost of buying over time.
Does this account for inflation?
No, this calculator shows the nominal value. To estimate "real" purchasing power, you should subtract the inflation rate from your expected return rate (e.g., if you expect 10% return but inflation is 4%, use 6% in the calculator).
