For more information about Excel cell references, please see Why use dollar sign ($) in Excel formulas. The second reference without the $ sign (B2) is relative and it adjusts based on the relative position of the cell where the formula is copied.

Because an absolute reference never changes no matter where the formula moves, it will always refer back to B2. In your running total formula, the first reference should always be an absolute reference with the $ sign ($B$2). To calculate a running total in Excel, you can use the SUM function combined with a clever use of absolute and relative cells references.įor example, to calculate the cumulative sum for numbers in column B beginning in cell B2, enter the following formula in C2 and then copy it down to other cells: How to calculate running total (cumulative sum) in Excel

This short tutorial shows how a usual Excel Sum formula with a clever use of absolute and relative cell references can quickly calculate a running total in your worksheet.Ī running total, or cumulative sum, is a sequence of partial sums of a given data set.
