Simple interest = 3200 X 8/100 X 3 = $ 768

We can calculate the compound interest with following interest

= Principle ( 1 + r/100)^t – Principle 

 Example : 

Find the compound interest on $ 8000 in 2 years at the rate of 5% compounded annually.

C.I. = 8000 ( 1+ 5/ 100)^2 – 8000 = $ 820

Principle = $ 50000, rate of interest = 5% Time = one and half year or 3 half years

 Total payment = 50000 ( 1+5/100)^3 = $53844.53
