📊 Investment Insight
Compound interest helps your money grow faster because interest is earned on both the original investment and accumulated interest.
What Is Compound Interest?
Compound interest is the process where interest is calculated on both the initial investment and previously earned interest. It is commonly called “interest on interest” because your investment continues growing exponentially over time.
Compound interest plays a major role in long-term wealth creation, retirement planning, SIP investments, FD growth, and overall financial planning.
Compound Interest Formula
A = P (1 + r/n)nt
Where:
A = Final Amount
P = Principal Investment
r = Annual Interest Rate
n = Compound Frequency
t = Investment Duration
This formula is widely used in banking, investment planning, mutual funds, fixed deposits, and wealth management calculations.
Real Life Compound Interest Example
Suppose you invest ₹1,00,000 at an annual interest rate of 12% for 10 years with yearly compounding.
Your investment would grow significantly because every year interest gets added to the original amount and future interest calculations include previously earned returns.
| Investment | Interest | Duration | Future Value |
|---|---|---|---|
| ₹1,00,000 | 12% | 10 Years | ₹3,10,585+ |
