Excel: How to Multiply Column by a Percentage


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

=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 column A 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 Excel

Suppose we have the following list of values in Excel:

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 the corresponding values in column A multiplied by 50%.

For example:

  • 10 * 50% = 5.0.
  • 15 * 5 0%= 7.5.
  • 18 * 50% = 9.
  • 20 * 50% = 10.
  • 25 * 50% = 12.5.

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.

Each value in column B will now be equal to the corresponding values in column A multiplied by 90%.

For example:

  • 10 * 90% = 9.
  • 15 * 90% = 13.5.
  • 18 * 90% = 16.2.
  • 20 * 90% = 18.
  • 25 * 90% = 22.5.

And so on.
