    Compound Interest

    Hello,

    Can anyone help me?

    I need a formula in Excel that calculates compound interest

    Principal sum of $5m
    Yielding a weekly return of 8%
    So returns accrue every 5 banking days (with no withdrawals)
    Minus a weekly commission fee of 5%
    Giving the NET monthly compounded result per month for 10 banking months.

    A week is 5 banking days and a month is a banking month of 20 days.

    Thanks very much!

    Helen

    Wouldn't it be just

    =5000000*(1.03^40 - 1)

    Hi,

    Thanks I will try it. I may be making it sound more complicated than it actually is.
    Does that include the weekly 8%?

    8% return minus 5% commission is net 3% per week, no?

    Re: Compound Interest

    Is there a way to beak the formula down so I can show the total after each of the ten years?
