We frequently use Google Sheets to average or sum any data. When we need to average a dataset that is based on a specific set of criteria, we compute the weighted average. Sometimes we need to calculate the weighted average with some conditions. We can use different Google Sheets functions to do that. In this article, we will demonstrate some methods to calculate the conditional weighted average in Google Sheets.

## A Sample of Practice Spreadsheet

## What Is Conditional Weighted Average?

A **weighted average** is an arithmetic mean that accounts for the relative importance of different data points. It means the average is calculated giving specific data more priority depending on their value or criteria. This gives a more accurate result than the regular arithmetic mean.

And a conditional weighted average is when the weighted average is calculated taking multiple conditions in importance.

## 5 Suitable Ways to Calculate Conditional Weighted Average in Google Sheets

Here we will show 5 easy and effective ways to calculate the weighted average in Google Sheets.

Let’s assume we have a dataset that contains data about 2 types of foods (**fruit** and **nut**) and their **quantity** and **unit price**. We will perform a conditional weighted average to find out the average unit price of one type of food (fruit).

Here with a few steps, we will show how to calculate the conditional weighted average of unit price. Follow the article to learn how to do that.

### 1. Applying Generic Formula

A simple generic formula can be used to determine the conditional weighted average. The generic formula is given below.

**Weighted Average= (Total of Weighted Terms)/(Total Number of Terms)**

The instructions to do that are given below.

**📌 Steps:**

- First, select cell
**E13**and enter the below formula.

`=(D5*E5+D8*E8+D9*E9+D11*E11)/(D5+D8+D9+D11)`

- Here,
**D5*E5**in the formula returns the product of quantity and unit price of**Avocado**i.e the 1st fruit in the dataset. So**D5*E5+D8*E8+D9*E9+D11*E11**returns the sum product of quantity and unit price for all fruits. So you get the**Total Weighted Terms**for the Fruit type. - The quantity is the weighting factor in this dataset. Now
**D5+D8+D9+D11**returns the sum of the quantities. So you get the**Total Number of Terms**for the generic formula.

### 2. Implementing SUMIFS Function

We can also use** the SUMIFS function** to find out the weighted average for different conditions. The **SUMIFS** function returns the sum of a range depending on multiple criteria. This will give output for conditional weighted average. Check the below steps to be able to do that.

**📌 Steps:**

- First, select
**F5**and enter the below formula to find the total price of the food product(Avocado). Next, use the**fill handle**tool to drag down the formula from cell**F6**to**F12**.

`=D5*E5`

- Then select cell
**F14**and enter the formula. Next, you will get the result for the weighted average of unit price for the Fruit category. You can get the unit price of nuts by replacing**Fruit**with**Nut**in the formula.

`=SUMIFS(F5:F12,C5:C12,"*Fruit*")/SUMIFS(D5:D12,C5:C12,"*Fruit*")`

**Formula Breakdown**

**SUMIFS(F5:F12, C5:C12,”*Fruit*”):**This formula sums the total price from cell range**F5: F12**if they are of the “Fruit” type in cell range**C5:C12**.**SUMIFS(D5:D12, C5:C12,”*Fruit*”):**This formula sums the quantity from cell range**F5: F12**if they are of the “ Fruit” type in cell range**C5:C12**.**SUMIFS(F5:F12, C5:C12,”*Fruit*”)/SUMIFS(D5:D1 2, C5:C12,”*Fruit*”):**If you divide the total price by quantity, you will get the weighted average of unit price.

### 3. Applying SUMPRODUCT and SUMIF Functions

Implementing the **SUMPRODUCT** and **SUMIF** functions together is another way of calculating the conditional weighted average. The **SUMPRODUCT** function calculates the sum of the products of two same-sized strings or ranges. The **SUMIF** function returns a conditional sum across a range. Here we will use these two functions to find out the weighted average. Follow the steps to learn how to do that.

**📌 Steps:**

- First, select cell
**E14**to input the below formula.

`=SUMPRODUCT((C5:C12="Fruit")*D5:D12*E5:E12)/SUMIF(C5:C12,"Fruit",D5:D12)`

- It will provide the result which is the weighted average value for Fruit unit price.

**Formula Breakdown**

**SUMPRODUCT((C5:C12=”Fruit”)*D5:D12*E5:E12):**This function multiplies values from**D5:D12**and**E5:E12**ranges if they are under fruit type from**C5:C12**.**SUMIF(C5:C12, “Fruit”, D5:D12):**This function just gives the sum of values from the range**D5:D12**if they fall under the Fruit type.- Finally dividing the output of the
**SUMPRODUCT**function by the output of the**SUMIF**function gives back the weighted average of the unit price for the fruits.

### 4. Utilizing AVERAGE.WEIGHTED and FILTER Functions

Google Sheets has a function dedicated to calculating the weighted average. We will use **the AVERAGE.WEIGHTED function** to calculate the conditional weighted average of unit price in Google Sheets. The **AVERAGE.WEIGHTED** function returns the weighted average of a set of values, given the values and the corresponding weights. We will also use **the FILTER function** to find the conditional weighted average of unit price for Fruits. You can follow the steps below to do this by yourself.

**📌 Steps:**

- First, select cell
**E14**and enter the formula in the cell.

`=AVERAGE.WEIGHTED(FILTER(E5:E12,C5:C12="Fruit"),FILTER(D5:D12,C5:C12="Fruit"))`

- Here, the
**FILTER**function will return the quantity and unit price for the fruits only. The output of this function will work as arguments of the**AVERAGE.WEIGHTED**function.

### 5. Using SUMPRODUCT, ISNUMBER, and SEARCH Functions

Alternatively, we can combine three functions to get the conditional weighted average in Google Sheets. We will use the **SUMPRODUCT**, **ISNUMBER**, and **SEARCH** functions to accomplish that. Read the following steps to do that.

**📌 Steps:**

- First, select cell
**E14**and insert the below formula to get the same result as earlier.

`=SUMPRODUCT((ISNUMBER(SEARCH("Fruit",C5:C12))*(D5:D12)*(E5:E12)))/SUMPRODUCT((ISNUMBER(SEARCH("Fruit",C5:C12))*(D5:D12)))`

**Formula Breakdown**

**SEARCH(“Fruit”,C5:C12):**The**SEARCH**function specifies the cells containing “Fruit” in the**C5:C12**range.**ISNUMBER(SEARCH(“Fruit”,C5:C12)):**The**ISNUMBER**function verifies whether the output of the**SEARCH**function is a number.**SUMPRODUCT((ISNUMBER(SEARCH(“Fruit”,C5:C12))*(D5:D12)*(E5:E12))):**This part returns the**Total Weighted Terms**for the fruits only.**SUMPRODUCT((ISNUMBER(SEARCH(“Fruit”,C5:C12))*(D5:D12))):**Here the**SUMPRODUCT**function returns the sum of quantities for fruits only.

## Things to Remember

- If you use the
**AVERAGE.WEIGHTED**function, make sure to enter values into every cell; otherwise, the formula will return an error. To avoid this issue put a “**0**” in blank cells.
