Key Takeaway: ₹5,000/month invested at 12% for 30 years = ₹1.76 Crore. Starting early is more important than investing more.
The 8th Wonder of the World
Albert Einstein reportedly called compound interest "the eighth wonder of the world." Whether he actually said it or not, the math behind compounding is truly magical.
What is Compound Interest?
Compound interest is interest earned on both your original investment AND on previously earned interest. It creates exponential growth over time.
The ₹5,000 SIP Example
Let's say you invest ₹5,000 per month in a mutual fund that gives 12% annual returns:
• After 10 years: ₹11.6 lakhs (invested ₹6 lakhs) • After 20 years: ₹49.9 lakhs (invested ₹12 lakhs) • After 30 years: ₹1.76 crore (invested ₹18 lakhs) Your ₹18 lakh investment becomes ₹1.76 Crore — that's almost 10x!
Starting at 25 vs 35: A ₹1 Crore Difference
Person A starts SIP of ₹5,000/month at age 25 (35 years): Invests ₹21L → Gets ₹3.25 Crore Person B starts SIP of ₹10,000/month at age 35 (25 years): Invests ₹30L → Gets ₹1.90 Crore Person A invested LESS money but got MORE — just by starting 10 years earlier!
5 Rules to Maximize Compounding
