First, let's start with the basic formula for calculating the simple interest for any investment; S.I=(P×R×T)/100, where P=Principal(i.e initial investment/capital), R=Interest Rate(by how much your cash will increase in value), T=Time.

Here, P=500(whatever currency you mean ), R=8%, T=4 years=4×12 months=48 months.

Note: You mentioned the fact that the interest is compounded monthly, which is why I converted Time(T) to months.

Using the above stated formula;



Total worth would be=S.I + P(The interest should be added to the Principal/Capital).


Therefore the total worth of your 500(whatever currency) after 4 years is 2,420(same currency).
