I have a spreadsheet that analyzes real estate. Some examples of the functions are Price per square foot and columns that clean up "0" entries for graphs. In other columns I have functions that then compile all properties that meet those criteria and were sold between Jan 1st and March 31st. As you can see it gets complex and I end up with many columns of information referring to each other.

My question is, does it make the spreadsheet faster to integrate the price per square foot column into all of the columns referring to it or is it faster to have multiple columns with less complex formulas?

Thanks in advance,

Brian
