SUMPRODUCT is one of the most useful excel functions.

Sumproduct function can help you to multiply and sum specified ranges or arrays in excel. In simple words, it will first multiply the corresponding cells from ranges and then sum up all the values.

In above example, I have used sumproduct to multiple and sum up the values from column D and column F. First, it has multiplied the values from column D with column F and then sums up the values.

By using excel sumproduct function you can perform a complex calculation in a single cell.

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

**array1**First array you want to multiply & then add.**[array2]**Second array you want to multiply & then add.

- If skip you to specify array2, Sumproduct will simply sum the array1.
- The maximum size of each array should be same. If array1 has 5 cells then cells in array2 should be 5.
- Text & other non-numeric entries will be treated as 0.

In the below example, I have used sumproduct to get a value on some conditions.

As I have already mentioned, if you do not specify array2, it will simply sum array 1. And, here I have used the same logic to get the value from a condition. Let me explain.

- First, it will check which vendor you have selected.
- Then it will check which week you have selected.
- And, return the value from the cell intersect on the both.

The array will work something like this when you select V-3 and W-2

Some awesome things you can do with sumproduct:

- Calculate Weighted Average With SUMPRODUCT
- Conditional Ranking With SUMPRODUCT
- Use Conditions in SUMPRODUCT
