You don't need to learn a complicated Excel function to calculate your company's annual sales. The program's SUM function returns the total sum from all of the values in specific cells. For example, the function can add the value of each cell in a range of consecutive cells, such as a range of cells representing the 12 months of the year. You only need your monthly sales data to use the function to get your annual sales total.
Step 1
Open a new spreadsheet, then enter the name of each month of the year in each cell from A1 to A12. For example, type "January" in cell A1, and then type "February" in cell A2.
