Excel/formula in Excel 2010

Question
I have a spread sheet that covers a calendar quarter, entering mileage and fuel usage for several trucks.  Each column has a sum at at bottom.  As the quarter progresses, new rows are inserted to keep the info for each truck together. How do I get my bottom row to continue to be the sum of each row above without knowing how many rows I will have by the end of the quarter, as usage changes from month to month?

Make sure you're using a RANGE of cells for your SUM, like

=SUM(A1:A20)

Then make sure you use INSERT ROWS or INSERT CELLS to insert new rows INSIDE of that range. The formula will automatically update for you.
