## Compound interest calculation

The formula that you can apply to find Compound Interest can be used as the amount after n years A_{n} is apparently equal to the initial amount that is A_{0} times one in addition to the annual interest rate r which is divided by the number of compounding periods in a year m which is raised to the power m times n:

## Compound interest formula

### Future value calculation

The future amount that is to be calculated after n years A_{n} is totally equal to the initial amount A_{0} multiplied one plus the annual interest with rate r and divided by the number of the compounding periods in an year m which is raised to the power of m times n:

A_{n} is the future value of the amount after n years.

A_{0} is the present amount that is present.

r is the annual interest rate on which the amount is given.

m is the number of compounding periods per year.

n is the total number of years for which the amount is given.

#### For Example,

If we have to find the future value of an amount after 7 years with the present value of $6,000 on an annual interest of 3%.

Solution:

*A*_{0} = $6,000

*r* = 3% = 3/100 = 0.03

*m* = 1

*n* = 7

*A*_{10} = $6,000·(1+0.03/1)^{(1·7)} = $4,933.42
