I have 3 columns in a Google Docs spreadsheet: A) Inventory purchased price, B) Inventory sold price, C) Difference between A and B (i.e. profit or loss)

Data is going to be entered manually into columns A and B. How do I make column C to 1) display the calculated amount for each row, and 2) color profitable sales in green and unprofitable in red?

  • For 2, you want "conditional formatting". There are already several questions here on that topic; just do a search. – ale Apr 11 '15 at 11:21

.. and for the first question, assuming your data start in row 2, in C2 try:

=ArrayFormula(if(len(A2:A)*len(B2:B), B2:B-A2:A,))

This formula should automaticcaly output the difference between B and A when data is entered. See if that works ?

  • It worked fantastically. Thank you very much! – Knocks X Apr 11 '15 at 16:38
  • How would I do it if all numbers are in one single column and I want to calculate the difference between the current row and the row above? Like =A2-A1 and make this continue down "forever". – Daniele Testa May 19 at 15:16
