# Excel: How to Multiply Column by a Constant

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.
