Goal Seek use + instead of Formula

When you use Goal Seek in Excel, it might not work right if you use a SUM formula. The results can look confusing.

Try to understand what value you want to reach and which number needs to change. Instead of just summing, focus on the actual gap or target.

Set Cell should be the formula you're trying to solve.

To Value is the number you want to get.

By Changing Cell is the input Excel should change.

Set it up properly and Goal Seek will work instantly.

Hope this helps someone. Just sharing a quick tip. Thanks.

    a quick tip ๐Ÿ™‚

    Example:

    Suppose you want A1 + A2 = 100, and you want Excel to change A2.

    Put in the Set Cell:

    =A1 + A2

    Set Cell: cell with that formula

    To Value: 100

    By Changing Cell: A2

    This works โ€” but the clearer way is: =TargetValue - (A1 + A2)

    Now your formula is literally โ€œgap to target,โ€ and Goal Seek just tries to zero it out.

     

    Hope it helps you
