calculate the difference between negative and positive values
I need to show the difference between costings for last month, compared
with this month. For example, last month a particular costing showed a profit of $100. This month is showing a loss of $200. I need to show that this month the difference between the costings is therefore $100, or, $100 dollars less than last month. Can anyone offer me the formula to do this? Sneaky second question!... it would be useful to display, in the above example, "$100 less", rather than "$100". Can this be done? Many thanks

calculate the difference between negative and positive values
When I went to school:
100(200)=100+200=300 [If it was $100 dollars less it would be 0 (zero) this month] so I contend the difference is $300 so the formula is: =A1B1 A1=Last month, B1=This Month For your second question, try: =IF(B1A1<0,ABS(B1A1) & " less",IF(B1A10,B1A1 & " more",B1A1)) A1/B1 as above HTH "watty" wrote: I need to show the difference between costings for last month, compared with this month.

Ah, the difference is $300, not $100. The signed difference is "newValue  oldValue". By "signed difference", I mean: negative for less; positive for more. In this case, (200)  100 = 300. If "oldValue" is in A1 and "newValue" is in A2, the difference (A3) is: =A2  A1 Sneaky second question!... it would be useful to display, in the above example, "$100 less", rather than "$100". Can this be done? In A3: =if(A2A1 < 0, text(A1A2,"$0") & " less", if(A2A1 0, text(A2A1,"$0") & " more", "no change") Note the reverse order "A1A2" in the "less" case. This produces a positive number like "$100 less" instead of a negative result like "$100 less".

calculate the difference between negative and positive values
Thanks for those very useful responses  I have been able to solve the
problem. One question following  using your suggested formulas I am also setting up fields to show that, for example, this month employee A is working for 1 hour 20 minutes longer that last month. This value is expressed as a decimal, i.e. the employee is working 1.33 hours more. The formula however only returns "1 hour more" and does not recognise the fractional part of the number. How can I adjust the formula to display this.
