# SUMPRODUCT Explained simple

The SUMPRODUCT function in Excel is a versatile function that can be used to perform a variety of calculations. It can be used to multiply corresponding elements in one or more arrays or ranges, and then return the sum of those products.

This is often useful for calculations that involve multiple criteria or conditions.

Here is an example of how you might use the SUMPRODUCT function with sample data. Let's say you have a table of data that looks like this:

 A B C 1 50 25 100 2 60 30 120 3 70 35 140 4 80 40 160

To use the SUMPRODUCT function with this data, you would first need to specify the arrays or ranges that you want to multiply together. In this case, let's say you want to multiply the values in column A by the values in column B, and then sum the products. To do this, you would enter the following formula into an empty cell:

=SUMPRODUCT(A1:A4, B1:B4)

This formula would multiply the values in cells A1, A2, A3, and A4 by the values in cells B1, B2, B3, and B4, respectively, and then return the sum of those products. In this case, the result would be 5000, because 50 x 25 + 60 x 30 + 70 x 35 + 80 x 40 = 5000.

You can also use the SUMPRODUCT function to perform calculations with multiple criteria or conditions. For example, let's say you want to find the sum of the values in column C, but only for the rows where the values in column A are greater than 60. To do this, you could use the following formula:

=SUMPRODUCT((A1:A4 > 60), C1:C4)

This formula would first create an array of logical values, with TRUE for each cell in column A that is greater than 60, and FALSE for all other cells. This array would look like this:

 A 1 FALSE 2 FALSE 3 TRUE 4 TRUE

The SUMPRODUCT function would then multiply this array by the values in column C, and return the sum of the products. In this case, the result would be 260, because the values in cells C3 and C4 (140 and 160) would be multiplied by the corresponding TRUE values in the array, and the other values would be ignored.

Overall, the SUMPRODUCT function is a powerful tool for performing calculations with multiple arrays or ranges in Excel. It can be used for a wide variety of calculations, and is often more efficient than using multiple formulas or functions to achieve the same result.
