Using SUM(IF()) as an array function instead of COUNTIF() with AND or OR criteria in Excel

Applies to: Microsoft Office Excel 2007Microsoft Office Excel 2003Excel 2010

Summary


In Microsoft Excel, the COUNTIF() function allows you to determine the number of cells in a range whose values match a certain criterion, but it does not allow you to use criteria involving the logical operators OR or AND. This article shows you how to use SUM(IF()) as an array function to accomplish that task.

More Information


The COUNTIF() function, introduced in Excel version 5.0, provides a convenient way to count, within a range, the cells whose values match a certain criterion. For example, if a worksheet has the following values in cells A1:J1

1 6 5 1 5 2 1 8 4 7
you can type the function =COUNTIF(A1:J1, 5) in cell A3, where it produces the result 2, that being the number of cells in the range A1:J1 with the value 5.

However, if you want to count the number of cells whose values are either 5 or 1, the COUNTIF() function is not appropriate because it does not recognize compound criteria such as "5 OR 1." For that purpose, you need to use SUM(IF()) as an array function.

To obtain this result for the preceding data, follow these steps:
  1. Start Microsoft Excel with a new worksheet.
  2. Type the values listed earlier in this section in cells A1:J1 of the worksheet.
  3. In cell A3, type the following function
    =SUM(IF((A1:J1=5)+(A1:J1=1), 1, 0))
    and then press CTRL+SHIFT+ENTER simultaneously to enter the array formula.
You receive the result 5, which is correct because there are two 5's and three 1's in the data range.
