Compound Interest Calculation

Formula for calculating compound interest:

Where,

• P = principal amount (initial investment)
• r = annual nominal interest rate (as a decimal)
• n = number of times the interest is compounded per year
• t = number of years
• A = amount after time t

Example usage:

An amount of $1500.00 is deposited in a bank paying an annual interest rate of 4.3%, compounded quarterly. Find the balance after 6 years.

A. Using the formula above, with P = 1500, r = 4.3/100 = 0.043, n = 4, and t = 6:

So, the balance after 6 years is approximately $1,938.op.
