    Question Increase Value until Value in another cell reaches target

    Hi All,

    Having difficulty creating a formula to calculate the following...

    I have a cost analysis form that calculates a profit margin (percentage) in cell S9 based on a lot of costs. I am looking to implement a formula in cell T9 that will find a number that results in the percentage in S9 in being 20%...

    Formula in Margin column S9 is "=SUM(T9/I9)*100"

    S9 - Margin %
    T9 - Profit Value £
    I9 - Cost Price £

    Maybe if the formula scrolls through increments of 0.01 until S9 equals 20???

    Everything I have tried seems to result in an error...PLEASE HELP

    Jamie

    Go to excel options and enable 'Iterative Calculation'

    Enter this formula into V2

    =S2/(1-U2)

    Then enter your desired margin into U2 as percentage. (Actual value, not formula).

    Re: Increase Value until Value in another cell reaches target

    That's amazing works perfectly!! Thank you so much!!

    Just out of curiosity, where does the 0.8392 come from? I understand the rest, just trying to make sense on this so I can use it again in the future.

    Thank you once again for your help

    Re: Increase Value until Value in another cell reaches target

    0.8392 can be calculated as follows-

    First sum up factors of all variable costs
    In our case, we have 0.1 and 0.034 as the factors for variable costs.

    Summing then up we get 0.134
    Now multiply this sum by tax factor i.e. 1.2 (20 %)
    (Similarly if tax is 30% multiply by 1.3)

    So we get 0.1608
    Now subtract this from 1 to get 0.8392

    Hope this makes it clear...

    Regards
    Sourabh

    Hoping you can help, I'm trying to use this formula in a similar spreadsheet.

    I can't for the life of me figure out where you're getting the 0.1 and 0.034 from the example sheet. Can you advise further please?

    Re: Increase Value until Value in another cell reaches target

    Hi.

    It's a forum rule that you start your own thread, rather than "piggy-backing" on someone else's thread. Why is it a rule?

    1. It helps prevent massive confusion arising - which will happen if it is not clear which question is being answered.

    2. The forum provides a public database for questions and answers. One thread = one question. Your problem will almost certainly be somewhat different.

    So please start your own thread and explain your own problem (make sure that, right from the start, you use a meaningful title (NOT things like "help needed" or "urgent problem"... think of the Google search terms that you would use to find the solution).

    A picture is worth 1,000 words. An Excel sheet is worth 1,000 pictures. So, prepare a SMALL sample sheet (10-20 rows, not thousands!!!). Make sure there is enough data to demonstrate your need. Make sure your desired results are shown, mock them up manually if necessary. Remember to remove ALL confidential information first!!!


    The yellow banner about sample worksheets, at the top of the screen tells you how to post a sheet here on the Forum.
