Let's say the original six are A1 thru A6:

10%
20%
30%
5%
25%
10%

Put the percentage of the new seventh item in B7
In B1 enter:
=(1-$B$7)*A1 and copy down thru B6. FOr example if the new seg was to be
33%, then:

10% 6.70%
20% 13.40%
30% 20.10%
5% 3.35%
25% 16.75%
10% 6.70%
33%

Thew new one takes as much room as you want, the old ones accomodate but
stay in proportion.

I am adjusting a market segmentation for a certain industry, which currently
contains 6 different segments, which add up to 100%. I want to add another
segment and have the total to remain at 100% this would mean that the other
categories should be reduced accordingly while still holding the same
weighting in the group. Is there a function that will help me with this?
