Understanding Compound Interest
Compound interest is interest calculated on the initial principal and accumulated interest from previous periods. It differs from simple interest, which is only calculated on the principal.
Compound Interest Formula:
[
A = P \times \left(1 + \frac{r}{n}\right)^{nt}
]
Where:
(A) = Future value of investment
(P) = Principal amount (initial investment)
(r) = Annual interest rate (decimal)
(n) = Number of times interest is compounded per year
(t) = Number of years
Example Compound Interest Calculation
Scenario:
Initial Investment: $10,000
Monthly Contribution: $200
Annual Interest Rate: 6%
Compounded Monthly
Investment Period: 20 years
Projected Future Value: $104,000 (approx.)
Interest Earned: $52,000
This demonstrates how regular contributions and compounding can grow your wealth significantly over time.
