Compound Interest Formula
Understanding how compound interest works
Standard Compound Interest Formula
A = P(1 + r/n)^(nt)
Where:
A = Final amount
P = Principal (initial investment)
r = Annual interest rate (decimal)
n = Number of times interest is compounded per year
t = Time in years
The Power of Compound Interest
Compound interest is often called the "eighth wonder of the world" because it allows your money to grow exponentially over time. The longer your money compounds, the faster it grows, as you earn interest on both your principal and previously earned interest.
