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

=CELL*CONSTANT

For example, you can use the following formula to multiply the value in cell A1 by 5:

=A1*5

You can then click and drag this formula down column A to multiply every value in column A by 5.

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

**Example: Multiply Column by a Constant 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 5:

=A2*5

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 5 times the values in column A.

For example:

- 10 * 5 =
**50**. - 15 * 5 =
**75**. - 18 * 5 =
**90**. - 20 * 5 =
**100**. - 25 * 5 =
**125**.

And so on.

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

For example, to multiply by 9 simply use the following formula:

=A2*9

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 9 times the values in column A:

For example:

- 10 * 9 =
**90**. - 15 * 9 =
**135**. - 18 * 9 =
**162**. - 20 * 9 =
**180**. - 25 * 9 =
**225**.

And so on.
