💡 What is Compound Interest?
Compound interest is the interest calculated on both the initial principal and the accumulated interest of previous periods. This means your money grows faster over time compared to simple interest.
Formula: A=P×(1+rn)ntA = P \times \left(1 + \frac{r}{n}\right)^{nt}A=P×(1+nr)nt
Where:
- A = Future Value
- P = Principal
- r = Annual interest rate (decimal)
- n = Number of times interest is applied per year
- t = Time in years
