Hi Mike,

1. All of your formula need to be revised either to C1/B1 or to (A1-B1)/B1

2. =if(A1="", "", B1/A1) revised to =IF(B1="","",C1/B1) will not cathc B1=0

3. =IF(ISBLANK(A1),"",B1/A1) same comment as above. Note OP said "some
months will have a zero"

A few options he

1. =if(iserror(your formula),"",your formula)

2. =if(A1="", "", B1/A1)

3. =IF(B1=0,0,A1/B1)

4. =IF(B1=0,"n/a",A1/B1)

5. =IF(ISBLANK(A1),"",B1/A1)

6. =IF(A1,B1/A1,"")

These are just a few that I found from previous posts by searching for #DIV/0.

Hope this helps

A1 is this month total
B1 is last months total
C1 is the difference, =A1-B1
This much I got
D1 is the difference in percentage, I use =(A1-B1)/B1 and I get my % in
black or (red) which is fine but now the problem

There are times we don't always handle a certain item so some months will
have a zero in either this month or last months calc and my % is all messed
up i get this #DIV/0 I think this means that you can not divide by zero but
how do I get around this.
