Question 1

What is compound interest?

Accepted Answer

Compound interest is the interest calculated on both the initial principal and the accumulated interest from previous periods. It makes your money grow faster over time compared to simple interest.

Question 2

How is compound interest different from simple interest?

Accepted Answer

Simple interest is calculated only on the original principal, while compound interest is calculated on the principal plus any previously earned interest. Over time, compound interest results in significantly higher returns.

Question 3

How often is compound interest calculated?

Accepted Answer

Compound interest can be calculated at different intervals: daily, monthly, quarterly, or annually. The more frequently interest is compounded, the faster your investment grows. This calculator uses monthly compounding.

Question 4

What is the Rule of 72?

Accepted Answer

The Rule of 72 is a quick way to estimate how long it takes to double your money. Divide 72 by the annual interest rate to get the approximate number of years. For example, at 8% interest, your money doubles in about 9 years.
