    Calculating interest rates
    I am not sure of the correct formula to calculate interest rates. If I had a PV of $400 a FV of $684 and 11 years to pay, what is my interest?

    The formula to remember is:

    FV = PV*(1+i)^N

    You need to solve this for I. Manipulating this to get I by itself gets you:

    I = (FV/PV)^(1/N) - 1

    You can take it from there.
