What Is Compound Interest?
Compound interest is the interest earned on both your initial investment (principal) and the interest that accumulates over time.
Unlike simple interest, which only earns interest on the principal, compounding allows your money to grow exponentially over time.
Compounding Interest Formula
The following formula is used for calculating the compounding interest.
A= P X (1+r/n)^n.tWhere:
A = Maturity Amount
P = Principal Amount
r = Annual Rate Of Interest
n = Number of compounding per year
t = Number of years
For example, if you invest ₹1,00,000 at 8% annual interest compounded yearly for 10 years,
A=1,00,000×(1+0.08/1)1⋅10 ≈ ₹2,15,892
This shows your money more than doubles in 10 years without any extra effort.
| Compounding Frequency | Example Calculation | Maturity Amount (₹) |
|---|---|---|
| Monthly | ₹1,00,000 @ 8% for 10 years, compounded monthly | ₹2,22,004 |
| Quarterly | ₹1,00,000 @ 8% for 10 years, compounded quarterly | ₹2,20,792 |
| Half-Yearly | ₹1,00,000 @ 8% for 10 years, compounded half-yearly | ₹2,18,994 |
| Yearly | ₹1,00,000 @ 8% for 10 years, compounded yearly | ₹2,15,892 |
Difference Between Simple Interest And Compound Interest
| Feature | Simple Interest (SI) | Compound Interest (CI) |
|---|---|---|
| Example Investment | ₹1,00,000 @ 8% for 10 years | ₹1,00,000 @ 8% for 10 years, compounded annually |
| Interest Earned | ₹80,000 | ₹1,15,892 |
| Total Maturity Amount | ₹1,80,000 | ₹2,15,892 |
| Calculation Method | A longer time increases interest proportionally | Interest calculated on principal + accumulated interest |
| Growth Over Time | Linear growth (same amount added each year) | Exponential growth (interest also earns interest) |
| Effect of Time | A longer time increases interest exponentially | Longer time increases interest exponentially |
| Best For | Short-term loans or fixed returns | Long-term investments to maximize growth |
| Compounding Benefit | None | Yes, reinvested interest grows wealth faster |
