How do I multiply a column by a percentage in Excel?

You can multiply a column by a percentage in Excel using Paste Special with the Multiply operation. Here's how:

Steps to Multiply a Column by a Percentage

1. Enter the Percentage: In an empty cell (e.g., cell C1), enter the percentage you want to use. For example, if you want to multiply by 15%, enter 15% or 0.15.

2. Copy the Percentage: Select the cell containing the percentage and copy it by pressing Ctrl + C.

3. Select the Range: Select the range of cells you want to multiply by the percentage. For example, if your data is in cells A1 to A5, select the range A1:A5 by dragging your mouse.

4. Use Paste Special: Right-click over the selected cell range. Choose Paste Special... (make sure you're clicking directly on "Paste Special..." and not the arrow next to it).

5. Choose Multiply: In the Paste Special dialog box:

   • Under the "Operation" section, click the Multiply option.
   • Under the "Paste" section, click Values.
   • Click OK.

Now, all the values in the selected column will be multiplied by the specified percentage.
