Interest Expense Equation


Introduction :

In this article we will discuss about the interest expensive equation. The “  Interest expense equation ” gives the period of the interest rate. Interest rate is not always charged yearly. It will be charged every 6 months, Monthly, some times Daily!. The “ Interest rate” contains two types,  simple interest rate and Second compound interest rate. Here compound interest only denoted by the interest expense equation because compound interest gives the expensive interest amount. In summary, to calculate the  simple interest rate, just find out the interest rate for one period and then multifly the number of periods. To calculate the compound  interest rate or interest expense equation, first find out the interest rate for the first period, add its total  and then calculate the interest rate for the next period, and so on..,

Formula

Formula for interest expense Equation:

Formula for simple interest:

simple interest SI = pnr

where 

p  =  principal amount
n  =  period
r  =  interest rate


Formula for compound interest or interest expense equation:

compound interest  CI   =   P (1  +`r/100` )n

Where

p  =  principal amount
n  =  period
r  =  interest rate

I am planning to write more post on solving linear equations with 3 variables, what are some prime numbers. Keep checking my blog.

Examples

Example For interest expense equation:

Ricky  paid $2000 at 10%  in finance then after 4 years what amount he will get? .   Finance using simple interest and compound interest method. But ricky expect interest expense method.

Solution:

Here,

Principal amount  p = $2000

Period        n  =  4 years

Interest  rate        r =  10%

Simple interest SI = pnr

SI =2000*4*10/100 

=  800

Simple interest    =  800

Compound interest or interest expense CI   =   P (1  +` r/100`   )n

CI = 2000( 1+`10/100` )4

=  2000(`11/100` )4

=  2000( `11/10*11/10*11/10*11/10` )

=  2928

CI   =  $2928     

Total amount in simple interest  = 2000+800

Simple interest amount is   =$2800

But the compound interest amout is $2928 .

Interest expensively gives the compound interest.

So after 4 years Ricky got $2928.
