divide a total, subtract one then format as a percentage

[cath63]

i need to create a formula that requires me to divide a total by the average
total, subtract 1 from the result before formatting as a percentage

=(AVERAGE(A1:A100)/SUM(A1:100))-1

The formula requires me to divide the store total by the average total and
then subtract one from the result, before formatting a percentage. I need to
use an absolute cell reference for the average total when copying formulas
for the store comparison figure. Will your answer do this?

Hi Cath

With your store values in A1:A100, then in B1
=A1-AVERAGE($A$1:$A$100)-1
Format the cell as Percentage.
Copy B1 down through B2:B100
Change the range to suit the number of rows of store data.

maybe i am confused..
"copying formulas for the store comparison figure."

let's say your store values are on A1:A10 [a total of 10 store]

if i want to compare store values of a same product.

1. on B1=A1/sum($A$1:$A$10) [click %]
hence each store will have a % of the total store
summing it to a total store equal to 100%.
this is the way i guess for comparing each store.

2. comparing the store with the MEAN average of all store
on C1=A1/AVERAGE($A$1:$A$10) [click %]
