How to Calculate the Average Excluding the Smallest & Highest Numbers in Excel
Calculating the average for a batch of data is frequently used in our daily life. But for some cases like statistic the average score in a competition, or price analysis, we often calculate the average excluding the smallest and highest numbers in the range of data. As we know we can use some formula like MAX or MIN to get the maximum value or minimum value in a range, so we can use formula combination to calculate the average excluding the MAX and MIN values. In this article, we will provide you some useful formulas to solve our problem.

Calculate the Average Excluding the Smallest and Highest Numbers by Formula 1
For example, we have a list of scores:
As we all know, we can use the total amount minus the smallest value and the highest value, then divide the total number-2, so for this case we can use the similar formula combination to calculate the average. Details see steps below.
Step 1: In any blank cell, enter the formula =(SUM(A2:A9)-MIN(A2:A9)-MAX(A2:A9))/(COUNT(A2:A9)-2).
Step 2: Click Enter to get the result. Verify that average is calculated properly.
Calculate the Average Excluding the Smallest and Highest Numbers by Formula 2
Above formula combination is a little complex, we can use a special function TRIMMEAN to calculate the average for some conditions.
Step 1: In any blank cell, enter the formula =TRIMMEAN(A2:A9,2/COUNT(A2:A9)).
Step 2: Click Enter to get the result. Verify that average is calculated properly. It is the same with the value calculated by the formula combination.
Calculate the Average Excluding the Smallest and Highest Numbers by User Defined Formula in VBA
If we frequently use the function to calculate the average in daily work, we can create a user defined function by VBA, then we can use the function directly.
Step 1: Click Developer tab->Visual Basic or Alt+F11 to load Microsoft Visual Basic for Applications window.
Step 2: Click Insert->Module to insert a module. Then Module1 is created.
Step 3: Enter below code in Module window.
Function AveExcludeSmallestHighest(myrange) As Variant With Application AveExcludeSmallestHighest = (.Sum(myrange) - .Max(myrange) - .Min(myrange)) / _ (.Count(myrange) - 2) End With End Function
See screenshot below:
In above code, we create the function as AveExcludeSmallestHighest. You can shorten the function name per your requirement.
Step 4: In any blank cell, enter =ave, verify that user defined function AveExcludeSmallestHighest is loaded.
Step 5: In any blank cell, enter the formula =AveExcludeSmallestHighest(A2:A9).
Step 6: Click Enter to get the result.
So after above steps, we can directly use this function to calculate the average in following work directly.
