I see one free legal solution. In a few words you should put two OnlineTableControls. Time range setting should be "2 - Number of measurement points", that Number is 1. You have to connect the same Archive Tag to both Tables. Then put a Button with VB Script that would get two values from Tables and make a calculation. Another Button could possibly make an export to Excel Workbook. I've made an example (in WinCC 7.0 SP3). I modifed it on the fly so it could have mistakes.
