Formula

The formula for calculating monthly CD interest is given by the compound interest formula:

Example

Let’s consider a CD with a principal amount of $10,000, an annual interest rate of 5%, and a duration of 2 years. Using the formula:

A=10000(1+120.05​)12×2

After calculating, the total amount at maturity would be approximately $11,038.02.
