When we have to add data based on a given criteria in Excel, the SUMIF function provides the perfect solution. In this article, we will learn how to use SUMIF in combination with Greater Than and Less Than functions.

Setting up the Data
Here we have a table of Scores from 73 to 98 and the corresponding number of students for each score. We want to know the total number of students who had the following scores:
 Greater than 90
 Greater than 75
 Less than 90
 Less than 75

SUMIF function in Excel
SUMIF is a function that sums the values in a specified range, based on a given criteria.
Syntax
=SUMIF(range, criteria, [sum_range])
Where
 Range: the data range that will be evaluated using the criteria
 Criteria: the criteria or condition that determines which cells will be added
 Sum_range: the cells that will be added; if left blank, “sum_range” = “range” which means that the range of data that will be added is the same range of data evaluated
Combine SUMIF with Greater Than Function
Example 1:
We want to know how many students had a score greater than 90.
In cell F4, enter the formula =SUMIF(B4:B13,”>90″,C4:C13).
Where


 B4:B13 is the range that we want to evaluate, containing the scores

 “>90” is the working formula to determine the scores greater than 90
 C4:C13 is the range that contains the data that we want to add, which is the number of students who have scores greater than 90
Figure 3. Entering the formula with SUMIF and Greater Than Function
Interpretation of formula: Compute the sum of Column C (No. of Students) if Column B (Score) is greater than 90
The result is 10 students. As shown below, the number of students with scores greater than 90 are highlighted in orange. The sum of 3, 4 and 3 is 10, which corresponds to the number of students who scored 91, 93 and 98.
Figure 4. Output: Sum of students with scores greater than 90
Example 2.
Determine the number of students with scores greater than 75.
Criteria: “>75”
In cell F5, enter the formula =SUMIF(B4:B13,”>75″,C4:C13).
Interpretation: compute the sum if score is greater than 75
Figure 5. Output: Sum of students with scores greater than 75
The result is 91, which is the sum of the students who scored greater than 75, as highlighted in the cells above.
Combine SUMIF with Less Than Function
Example 3:
Determine the number of students with scores less than 90.
Criteria: “<90”
In cell F8, enter the formula =SUMIF(B4:B13,”<90″,C4:C13).
Interpretation: compute the sum if score is less than 90
Figure 6. Entering the formula with SUMIF and Less Than Function
The result is 71, which is the sum of the students who scored less than 90, as highlighted in the cells below.
Figure 7. Output: Sum of students with scores less than 90
Example 4:
Determine the number of students with scores less than 75.
Criteria: “<75”
In cell F9, enter the formula =SUMIF(B4:B13,”<75″,C4:C13).
Interpretation: compute the sumif score is less than 75
The result is 9, as shown below.
Figure 8. Output: Sum of students with scores less than 75
