How It Works
Understanding compound interest
Compound Interest Formula:
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
PMT = Regular contribution amount
Compound interest allows your investment to grow exponentially over time. The more frequently interest is compounded, the more you earn. Regular contributions can significantly boost your returns.
