What Is Compound Interest & Why Does It Matter?
Compound interest is the “interest on interest” – meaning your earnings grow exponentially over time. Unlike simple interest (which only applies to the principal amount), compound interest reinvests your returns, accelerating wealth growth.
Key Benefits of Compound Interest
✔ Faster Wealth Growth – Your money works harder for you.
✔ Long-Term Financial Security – Small investments today can become substantial sums.
✔ Power of Time – Starting early maximizes returns due to compounding effects.
Example:
If you invest ₹10,000 at 8% annual interest compounded monthly:
- After 10 years: ₹22,196
- After 20 years: ₹49,268
- After 30 years: ₹109,357
See how just ₹10,000 can grow 10x?
