Google Sheets: How to Multiply Column by a Percentage


You can use the following basic formula to multiply a column by a percentage in Google Sheets:

=CELL*(PERCENT/100)

For example, you can use the following formula to multiply the value in cell A1 by 50%:

=A1*(50/100) 

You can then click and drag this formula down to multiply every value in column A by 50%.

The following example shows how to use this formula in practice.

Example: Multiply Column by a Percentage in Google Sheets

Suppose we have the following list of values in Google Sheets:

We can use the following formula to multiply the value in cell A2 by 50%:

=A2*(50/100) 

Next, we can hover over the bottom right-hand corner of cell B2 until a tiny “+” appears. Then click and drag down to all of the remaining cells in column B:

All of the values in column B are equal to 50% of the values in column A.

For example:

  • 50% of 10 is 5.
  • 50% of 15 is 7.5
  • 50% of 18 is 9.
  • 50% of 20 is 10.

And so on.

To multiply by a different percentage, simply change the value used in cell B2.

For example, to multiply by 90% simply use the following formula:

=A2*(90/100) 

Then click and drag this formula down to all of the remaining cells in column B.
