How to Multiply Two Columns in Google Sheets With a Simple Formula

Key Takeaways:

  • Multiplying two columns in Google Sheets is a straightforward process that can be accomplished using a simple formula.
  • The formula to multiply two columns is =A1*B1, where A1 and B1 are the cell references for the values you want to multiply.
  • You can easily copy and paste the formula down the columns to perform the multiplication for all rows.
  • Google Sheets provides various methods to multiply columns, including using the PRODUCT function and array formulas.
  • Multiplying columns is a fundamental operation in spreadsheets and is useful for calculations involving quantities and prices, among other applications.

Multiplying values across columns is a common operation in spreadsheets, whether you’re calculating sales figures, managing budgets, or performing data analysis. Google Sheets, a powerful and user-friendly spreadsheet application, makes this task incredibly simple with its built-in formulas and functions. In this article, we’ll explore how to multiply two columns in Google Sheets using a straightforward formula.

The Basic Multiplication Formula

The formula to multiply two values in Google Sheets is as easy as it gets: =A1*B1. Here, A1 and B1 are the cell references for the two values you want to multiply. When you enter this formula into a cell, Google Sheets will perform the multiplication and display the result.

For example, let’s say you have a column with quantities (Column A) and another column with prices (Column B). To calculate the total cost for each row, you can use the multiplication formula in Column C:

Quantity (A)Price (B)Total Cost (C)

Once you’ve entered the formula in the first row of Column C, you can copy and paste it down the column to perform the multiplication for all rows.

Tip: Use absolute cell references (e.g., =$A$1*$B$1) if you want to multiply a column by a fixed value in another column.

Copying the Formula Down the Columns

To copy the formula down the columns, follow these steps:

  1. Enter the formula =A1*B1 in the first row of the destination column (Column C in our example).
  2. Click on the cell containing the formula to select it.
  3. Hover your mouse over the bottom-right corner of the selected cell until you see a small square (the fill handle).
  4. Click and drag the fill handle down the column to copy the formula to the remaining rows.

As you drag the fill handle, Google Sheets will automatically adjust the cell references in the formula for each row, ensuring that the correct values are multiplied.

Using the PRODUCT Function

While the basic multiplication formula is straightforward, Google Sheets also provides a dedicated function for multiplying a range of values: the PRODUCT function. This function takes a range of cells as its argument and returns the product of all the values in that range.

For example, to multiply the values in Column A by the corresponding values in Column B, you can use the following formula:

=PRODUCT(A1:A10, B1:B10)

This formula multiplies the values in the range A1:A10 by the values in the range B1:B10. You can adjust the ranges to suit your needs.

Using Array Formulas

Another powerful method for multiplying columns in Google Sheets is to use array formulas. Array formulas allow you to perform operations on entire arrays (ranges) of data simultaneously.

To multiply two columns using an array formula, follow these steps:

  1. Select the range of cells where you want the results to appear.
  2. Enter the following formula: =A1:A10*B1:B10 (adjust the ranges as needed).
  3. Press Ctrl + Shift + Enter (Windows) or Cmd + Shift + Enter (Mac) to enter the array formula.

Google Sheets will multiply the corresponding values in the two columns and display the results in the selected range.

Note: Array formulas must be entered using the Ctrl + Shift + Enter or Cmd + Shift + Enter keyboard shortcut. This tells Google Sheets to treat the formula as an array formula.

Applications of Multiplying Columns

Multiplying columns in Google Sheets has numerous practical applications, including:

  • Calculating sales figures: Multiply the quantity sold by the unit price to determine the total revenue for each product.
  • Managing budgets: Multiply the number of items by their respective costs to calculate the total expenses.
  • Data analysis: Multiply data points by weights or coefficients to perform various statistical calculations.
  • Unit conversions: Multiply values by conversion factors to convert units (e.g., inches to centimeters, pounds to kilograms).
  • Scaling values: Multiply a column of values by a constant factor to scale them up or down.

By mastering the art of multiplying columns in Google Sheets, you’ll be able to perform a wide range of calculations efficiently and accurately.


Q: How do I multiply a column by a fixed value?

To multiply a column by a fixed value, use the following formula:

=A1*[fixed value]

Replace [fixed value] with the actual value you want to multiply the column by. For example, =A1*2 will multiply the value in cell A1 by 2.

You can then copy and paste this formula down the column to multiply all values by the fixed value.

Q: Can I multiply more than two columns at once?

Yes, you can multiply multiple columns simultaneously using the PRODUCT function or array formulas. For example, to multiply the values in Columns A, B, and C, you can use the formula:

=PRODUCT(A1:A10, B1:B10, C1:C10)

Or, for an array formula:


Q: How do I handle errors when multiplying columns?

If you encounter errors when multiplying columns, such as #VALUE! or #DIV/0!, it’s likely due to invalid or missing data in one or more cells. To handle these errors, you can use the IFERROR function in combination with your multiplication formula.

For example:

=IFERROR(A1*B1, 0)

This formula will display 0 instead of an error if there’s an issue with the multiplication operation.

Q: Can I multiply columns with different lengths?

Yes, you can multiply columns with different lengths using array formulas. Google Sheets will automatically handle the mismatch by replicating the shorter array to match the length of the longer array.

However, it’s generally recommended to ensure that your data is properly structured and aligned before performing calculations to avoid potential errors or unexpected results.

By following the techniques outlined in this article, you’ll be able to confidently multiply columns in Google Sheets, streamlining your calculations and improving your productivity.
