The SUMIF function is a built-in function in Excel that is categorized as a *Math/Trig Function*. It can be used as a worksheet function (WS) in Excel. As a worksheet function, the SUMIF function can be entered as part of a formula in a cell of a worksheet. You can try the SUMIF function to add numbers in a range based on multiple criteria.

*To learn how to use SUMIF, we also have to know what is SUMIF and when can we use it?*

**What is the SUMIF Function?**

The Excel SUMIF function finds the values in a supplied array, that satisfy given criteria, and returns the sum of the corresponding values in a second supplied array.

**When to use SUMIF?**

SUMIF Function is used to add the specified cells based on the single or multiple supplied criteria. Sometimes we require conditional sum in Excel then we can use this function to add all numbers in a particular given range. SUMIF function is based on the three parameters- range, criteria, and sum_range. Every parameter has its own functionality and also depends on **SUMIF **multiple criteria.

**Function Syntax**

The SUMIF Function in Excel has the following syntax:

*range, criteria, sum_range*)

**Parameters**

** range: **The range of cells that you want to apply the

*criteria*against.

** criteria:** The criteria used to determine which cells to add.

** sum_range: **Optional. It is the range of cells to sum together. If this parameter is omitted, it uses

*range*as the

*sum_range*.

*Now, let see how to use SUMIF to excel with a Case Study.*

**Case Study: **Consider that we have a shop and 5 people have ordered goods from us. Some people have paid us, but some haven’t. We want to calculate how much in total has been paid to us and how much is still owed.

## We can do it using SUMIF.

*Let’s go through the following steps.*

**Step 1:** Open Excel sheet and from Row 1, create three columns named Customer, Product Price and Payment Status. Enter data under these 3 columns as shown in the above picture. Here we will calculate:

**Total Paid Price**(Cell A10)**Total Due Price**(Cell A11)**Sum of product prices that sold over $100**(Cell A12)

In cells **B10, B11,** and **B12**, we’ll use a **SumIF** function to work out **Total Paid Price**, **Total Due Price, **and **Sum of product prices that sold over $100**. Here’s the SumIF function again:

**Calculate Total Paid Price**

The range of cells that we want to check is **True** and **False** values in the **C **column. The criteria is whether they have paid (**True**) and the Sum_Range is what we want to add up (in Column **B**).

**Step 2:** In cell B10, enter the following formula:

**Step 3: **Press **Enter**. Excel should give you the answer **265** in cell **B10**. In the formula, we told **SumIF** to first check the values in the cells **C3** to **C7**(range). Then we said look for a value of **TRUE** (criteria). So we wanted the values in the **B** column adding up if a criterion of **TRUE** was indeed found (sum_range). Finally, we got the result **265** that has been paid in total.

**Calculate Total Due Price**

**Step 4:** In cell **B11**, enter the following formula:

=SUMIF(C3:C7, FALSE, B3:B7)

**Step 5:** Press **ENTER**. Excel should give you the answer **313** in cell **B11**. In the formula, we told SumIF to first check the values in the cells **C3** to **C7** (range). Then we said look for a value of **FALSE** (criteria). So we wanted the values in the **B** column adding up if a criterion of **FALSE** was indeed found (sum_range). Finally, we got the result **313** is **Total Due Price**.

**Calculate the Sum of product prices that sold over $100**

**Step 6: **In cell **B12**, enter the following formula:

**Step 7:** Press **ENTER**. Excel should give you the answer **544** in cell **B12**. In the formula, we told SumIF to first check the values in the cells **B3** to **B7** (range). Then we said look for a Price value higher than **$100**. So we wanted the values in the **B** column adding up if a criterion of **>100 **was indeed found (sum_range). Finally, we got the result **544** is **Sum of product prices that sold over $100**.

**Tips: **There are many ways to find out a particular Sum. Say, if you want to calculate the total price sold out to a particular customer named **Joni**, then just shift your *range* of that formula from **B3:B7** to **A3:A7** and type criteria like the name of customer **Joni **then select the *sum_range ***B3:B7**. So, the formula would be:
