How to count unique values based on multiple criteria in Excel?
This article, I will take some examples for you to count unique values based on one or more criteria in a worksheet. The following detailed steps may help you.
Count unique values based on one criteria
Count unique values based on two given dates
Count unique values based on two criteria
Count unique values based on three criteria
Count unique values based on one criteria
For example, I have the following data range, now, I want to count the unique product that Tom sale.
Please enter this formula into a blank cell where you want to get the result, G2, for instance:
=SUM(IF("Tom"=$C$2:$C$20, 1/(COUNTIFS($C$2:$C$20, "Tom", $A$2:$A$20, $A$2:$A$20)), 0)), and then press Shift + Ctrl + Enter keys together to get the correct result, see screenshot:
Note: In the above formula, “Tom” is the name criteria that you want to count based on, C2:C20 is the cells contains the name criteria, A2:A20 is the cells that you want to count the unique values.
Count unique values based on two given dates
To calculate the unique values between two given dates, for example, I want to count the unique product between the date range 2016/9/1 and 2016/9/30, please apply this formula:
=SUM(IF($D$2:$D$20<=DATE(2016, 9, 30)*($D$2:$D$20>=DATE(2016, 9, 1)), 1/COUNTIFS( $A$2:$A$20, $A$2:$A$20, $D$2:$D$20, "<="&DATE(2016, 9, 30),$D$2:$D$20, ">="&DATE(2016, 9, 1))), 0), and then press Shift + Ctrl + Enter keys together to get the unique result, see screenshot:
Note: In the above formula, the date 2016,9,1 and 2016,9,30 are the start date and end date that you want to count based on, D2:D20 is the cells contain the date criteria, A2:A20 is the cells that you want to count the unique values from.
Count unique values based on two criteria
If you want to count the unique product that Tom sale in September, the following formula can help you.
Please enter this formula into a blank cell to output the result, H2, for example.
=SUM(IF(("Tom"=$C$2:$C$20)*($D$2:$D$20<=DATE(2016, 9, 30)*($D$2:$D$20>=DATE(2016, 9, 1))), 1/COUNTIFS($C$2:$C$20, "Tom", $A$2:$A$20, $A$2:$A$20, $D$2:$D$20, "<="&DATE(2016, 9, 30),$D$2:$D$20, ">="&DATE(2016, 9, 1))), 0) and then press Shift + Ctrl + Enter keys together to get the unique result, see screenshot:
Notes:
1. In the above formula, “Tom” is the name criteria, 2016,9,1 and 2016,9,30 are the two dates that you want to count based on, C2:C20 is the cells contains the name criteria, and D2:D20 is the cells contain the date, A2:A20 is the range of cells that you want to count the unique values.
2. If you need to use an “or” criteria to count the unique values, such as, calculate the products which sold by Tom or in South region, please apply this formula:
=SUM(--(FREQUENCY(IF(("Tom"=$C$2:$C$20)+("South"=$B$2:$B$20), COUNTIF($A$2:$A$20, "<"&$A$2:$A$20), ""), COUNTIF($A$2:$A$20, "<"&$A$2:$A$20))>0)), and remember to press Shift + Ctrl + Enter keys together to get the unique result, see screenshot:
Count unique values based on three criteria
To count the unique product with three criteria, the formula may be more complex. Let’s say, calculating the unique products which are sold by Tom in September and in region North. Please do as this:
Enter this formula into a blank cell to output the result, I2, for example:
=SUM(IF(("Tom"=$C$2:$C$20)*($D$2:$D$20<=DATE(2016, 9, 30))*($D$2:$D$20>=DATE(2016, 9, 1))*("North"=$B$2:$B$20), 1/COUNTIFS($C$2:$C$20, "Tom", $A$2:$A$20, $A$2:$A$20, $D$2:$D$20, "<="&DATE(2016, 9, 30), $D$2:$D$20, ">="&DATE(2016, 9, 1), $B$2:$B$20, "North")), 0), and then press Shift + Ctrl + Enter keys together to get the unique result, see screenshot:
