What is Compound Interest?

Compound interest is interest calculated on both the initial principal and the accumulated interest from previous periods. It is the "interest on interest" that makes investments grow exponentially over time.

Compound Interest Formula

A = P ร— (1 + r/n)^(nร—t)
CI = A โ€“ P
Where: P=Principal, r=Annual rate, n=Compounding frequency, t=Time
What is the Rule of 72?
The Rule of 72 estimates how long it takes to double your money. Divide 72 by the annual interest rate. E.g., at 12% interest, money doubles in 72/12 = 6 years.
Which compounding is best?
Daily compounding gives the highest returns, followed by monthly, quarterly, half-yearly, and yearly. The difference becomes significant over long periods.
