What is Compound Interest?
Compound interest means earning interest not only on your principal amount but also on the accumulated interest from previous periods. It is often referred to as “interest on interest” and is a key concept in growing wealth.
Formula of Compound Interest
A = P (1 + r/n)^(nt)
Where:
A = Final Amount
P = Principal Investment
r = Annual Interest Rate (in decimal)
n = Number of times interest is compounded per year
t = Time in years
