Interest question maths?

Posted at: 2014-12-05 
Simple interest on 1800 fro 4 years is

Simple interest = Principle x Rate x time

Simple interest = 1800 x 6.5% x 4 = 468.00

When compounded

Future value after 4 years will be

FV = PV x (1 + i)^n

FV = 1800 x (1 + 6%)^4

FV = 2,272.46

Interest = FV - PV = 2,272.46 -1800.00 = 472.46

So the second account pays more interest.

yes

I have $1800 to invest for four years and have decided to deposit my money in the Super Duper Bank. If I choose the Gold account, I earn simple interest of 6.5% per annum, but I have to withdraw my interest earned at the end of each year. If I choose the Platinum account, I earn interest of 6% per annum but I will leave the interest earned during each year to be added to the principal each year, which means that my interest is compounded.

Which account should I put my money in? and why?
