Exploring SUMPRODUCT Uses in Data Analysis

The Excel SUMPRODUCT Function is categorized under Excel Math and Trigonometry functions. The function multiplies the corresponding components of a given array and then returns the sum of the products. It is used to calculate a weighted average.

While the SUMPRODUCT Function is used more by financial analysts, it is also very handy for many other purposes. Why? 

It can handle arrays in different ways and help in comparing data in two or more than two ranges. It also helps in calculating data with multiple criteria.

Have you ever felt like you're just scratching the surface of Excel's SUMPRODUCT function? Is it just for multiplying and adding numbers? 

Let’s dive deep into the SUMPRODUCT in Excel, a function with much more than meets the eye. 

What is the SUMPRODUCT Formula in Excel

The SUMPRODUCT Syntax

=SUMPRODUCT(array1,[array2],[array3],…)

The SUMPRODUCT function uses the following arguments:

• Array1 (required argument) – This is the first array or range that we wish to multiply and subsequently add.
• Array2, Array 3 (optional argument) – This is the second (or third) array or range we wish to multiply and add.

The SUMPRODCUT Excel function is a Math or Trig function that allows you to multiply ranges of cells and arrays and returns the product's sum. It multiplies the supplied array values before adding them. 

You can type the SUMPRODUCT function onto a worksheet cell as a formula component. It is a beneficial function that can be used in various ways depending on your needs. 

It can handle arrays in multiple ways and compare data in two or more ranges. Additionally, it aids in data calculations involving several criteria.

Properties of SUMPRODUCT Function in Excel

Now that you know what a SUMPRODUCT in Excel IS, let’s understand its properties. 

• Array 1: One array is the bare minimum that must be provided to the SUMPRODUCT function. 
• If only one array is provided, the function returns the total of all the elements in this array. 
• If the array specified as parameters does not have the same amount of columns and rows, then the function returns the #VALUE! Error
• The SUMPRODUCT function treats any non-numeric values in the arrays supplied as parameters as 0s.
• The SUMPRODUCT function accepts up to 30 arrays as parameters.
• The non-numeric entries in an array are treated as zeroes by the SUMPRODUCT excel function.

You must be mindful of these properties before using the SUMPRODUCT function.

How to use the SUMPRODUCT Excel function 

To help you understand the SUMPRODUCT function, we’ll use real calculations you can follow and understand.

SUMPRODUCT syntax

=SUMPRODUCT(array1,[array2],[array3],…)

Example 1:

Suppose we have the following data in Excel:

We wish to find out the total sales for the West region. The formula to be used is:

We provided the double negative (—-) to force Excel to convert the TRUE and FALSE values into 1s and 0s.

Here is a virtual representation of the two arrays as first processed by SUMPRODUCT:

Explanation:

The first array contains the TRUE/FALSE values that result from the expression C4:C12=”WEST”, and the second array is the contents of D4:D12.  Each item in the first array will be multiplied by the corresponding item in the second array.

However, in the current state, the result of SUMPRODUCT will be zero, as the TRUE and FALSE values will be treated as zeroes. We need the items in array 1 to be numeric, so we need to convert them into 1’s and 0’s. This is where the double negative comes in, as it will treat TRUE as 1 and FALSE as 0.

We get the result below:

Example 2: Weighted Averages 

One key and common use of the SUMPRODUCT function in Excel is calculating a weighted average where each value is assigned a given weight. 

Here is an example:

Suppose we are given the following data:

Assume the values are given in cells C2:C8 and the weights in cells D2:D8. The weighted average SUMPRODUCT formula is:

With the calculation, we get the result below:

Notes about the SUMPRODUCT Excel Function 

1. The SUMPRODUCT in Excel is used to calculate sums and a weighted average. Two basic functions. 
2. #VALUE error – Occurs when the arrays provided do not share the same dimensions.
3. The SUMPRODUCT function will treat non-numeric entries in the array as zeroes.
4. SUMPRODUCT accepts up to 255 arguments in Excel 2016, Excel 2013, Excel 2010, and Excel 2007, and 30 in earlier Excel versions.
5. Logical tests inside arrays will create TRUE and FALSE values. In most cases, it is advisable to convert them to 1’s and 0’s.
6. SUMPRODUCT can often use the result of other functions directly. It is commonly used with LEN, or with other functions such as ISBLANK, ISTEXT, VLOOKUP, etc. A few examples are:
• Two-way lookup in Excel – SUMPRODUCT formula helps look up a value at the intersection of a given row and column.
• Count characters in Excel – Used to count the total or specific characters in a range.
• SUMPRODUCT for counting words in Excel – The function can be used to get the total number of words in a defined range or count only specific words.
• How to count distinct values – It can be used to find out how many different values appear in a range (unique plus first duplicate occurrences).
• Count duplicates and unique values – The SUMPRODUCT and COUNTIF functions help count duplicates and unique values in a column or between two columns.
• SUMPRODUCT and MONTH can be used to get a sum of values for a given month.

Uses of SUMPRODUCT

The SUMPRODUCT function in Excel is a versatile tool that can handle various tasks. It extends well beyond simple multiplication and array summation. At its core, SUMPRODUCT calculates the sum of the products of corresponding numbers in one or more ranges. 

Basic use:

Calculating the sum of the products of comparable numbers in one or more ranges is the most typical and fundamental usage of sumproduct.

For example: 

Explanation: 

The SUMPRODUCT performed this calculation: (2*250)+ (4*1000)+ (4*1000)+ (3*50)

One of the basic uses of SUMPRODUCT is to calculate total amounts by multiplying corresponding numbers in two or more arrays and then summing those products. For example, if you have arrays of quantities and unit prices, SUMPRODUCT can calculate the total cost. 

The function requires the ranges to have the same dimensions; otherwise, it returns an error. If non-numeric entries are present, they are treated as zeros​​.

SUMPRODUCT is not limited to basic calculations. It excels in scenarios requiring conditional sums and counts, supporting both AND and OR logic within its syntax. 

This makes it a robust alternative to functions like COUNTIFS and SUMIFS. For instance, you can sum values based on multiple conditions across different ranges, calculate weighted averages, or even count the number of occurrences of specific conditions within your data set​​.

Moreover, SUMPRODUCT can be employed for advanced tasks, such as two-way lookups, character counting in cells, or even distinguishing unique values within a range. Once mastered, it's a function that can significantly enhance your Excel data manipulation and analysis capabilities​​.

Advanced Use

The SUMPRODUCT function is incredibly flexible and can achieve the same outcome as several Excel's built-in functions or even array formulae!

To understand it better, let's look at The COUNTIF function, which counts the number of cells with precisely one moon.

See the example below: 

Now, you’ll find the same result if you use the SUMPRODUCT function.

Explanation: --(A1:A7="moon") reduces to the below-mentioned array constant:

--{TRUE;FALSE;FALSE;FALSE;TRUE;TRUE;FALSE}

The double negative -- drives these Booleans to 1's and 0's (TRUE=1, FALSE=0). That results in:

{1;0;0;0;1;1;0}

The SUMPRODUCT method receives this array constant as an argument and returns three as a result.

Advanced Applications of SUMPRODUCT

SUMPRODUCT in Excel is not just for simple multiplication and addition; it's a powerful tool for advanced data analysis, especially when dealing with data conditions. This function can perform conditional summing, a huge advantage over more complex nested IF statements.
