    I can't figure out how to repeat a calculation X amount of times. Specifically, i want to discount 2,020 by 10% X amount of times. So it should look like this (if X=3):
    ((2,020-(1-.1))(1-.1))(1-.1)
    which should equal 1472.58

    any suggestions?

    How about:

    =2020*(1-i)^x

    Where i = 10% and x = 3

    Hi,

    Are you sure you are applying the discount correctly?

    Adam's suggestion is correct, but if you are using this in a financial calculation (IRR, NPV, etc.), you would use:

    Amount/(1+rate)^number of periods

    =2020/(1.1^3) = 1517.66.

    I think you want Adam's answer, but this is another understanding of discount rates.

    Bye,
    Jay

    My bet is that princesslisa is in retailing, and she's marking down her inventory.
