## What Is VBA SUM Function?

The VBA Sum function is a method used to calculate the sum of values in a range or an array. It is similar to the SUM function in Excel, but it’s used within VBA code to perform calculations programmatically.

Look at the example below. A subroutine is created to perform the Sum cells in a given range. The Range is from cells A1 to A6.

The sum is printed in the Immediate tab as follows. The sum of the values from cells A1 to A6 is 196.

###### Key Takeaways

- The Sum function in VBA is similar to its Excel counterpart but is used within VBA code for programmatic calculations. It can handle both single-cell ranges and multi-cell ranges.
- It supports both numerical values and cell references as arguments.
- You can sum values from different ranges, worksheets, or workbooks.
- The function returns the sum of the provided values or ranges as a result.
- Ensure that the ranges provided are properly formatted and include all the correct information, otherwise, it may lead to unexpected results.
- Ranges can be contiguous or non-contiguous and can also be named ranges.

### Syntax

There are two ways in which you can call the VBA Sum formula. They are:

**Application.WorksheetFunction.Sum([Range])**

Or

**WorksheetFunction.Sum([Range])**

Where,

**Range: **This is the range of cells or array of values for which you want to calculate the sum.

### How to use VBA SUM function?

Here is a simple example of how to use the VBA sum column to last row formula.

Follow these simple steps to replicate this in your Excel Workbook.

**In the newly opened Excel Workbook, choose the “Developer” icon in the Excel toolbar and click on it.**

In the Developer section, select “Visual Basic”. It opens the VBA editor.

In the editor, in the title bar, click the “Insert” button and select the “Module” option.**Name the subroutine to find the sum of an entire row.****Call the VBA Sum function for the entire row by naming the row number in the Range function, as shown below. Store this value in another cell, F7.**

**Code:**

**Sub RowSum()**

** Range(“F7”) = WorksheetFunction.Sum(Range(“10:10”))**

**End Sub**

**Step 4: **Click “F5” or the “Run” icon on the activity bar in the Excel VBA Editor to run the subroutine.

The sum is printed in cell F7.

### Examples

See the different ways in which you can use the VBA Sum function to use the VBA sum cells formula.

#### Example #1

Suppose you have an Excel table with a list of items you’ve purchased. You want to find the total amount you want to pay for the bill. Using a table is more advantageous since this makes it more dynamic. You can call the range of the table and find its sum using the VBA Sum function.

**Step 1: **Start the procedure by naming the subroutine to find the sum using the VBA SUM cells formula to do so.

**Step 2: **Define a ListObject variable and define the table under that.

**Step 3: **Get all the values under the column of the table you want to find the sum of. Using ListColumns, name the column and take all the data under the column.

**Step 4: **Define an Integer variable where you can store the sum of all the values. Then, call the VBA Sum formula of the range of values stored in the previous step.

**Step 5: **Print the total price in a Message Box in VBA. Call the vbInformation icon for cosmetic purposes.

**Code:**

**Sub SumOfTable()**

** Dim tbl As ListObject**

** Set tbl = ThisWorkbook.Sheets(“Sheet1”).ListObjects(“Table1”)**

** Dim columnRange As Range**

** Set columnRange = tbl.ListColumns(“Price”).DataBodyRange**

** Dim SumRan As Integer**

** SumRan = WorksheetFunction.Sum(columnRange)**

** MsgBox “The amount to be paid is: ” & SumRan, vbInformation**

**End Sub**

**Step 6: **Press “F5” to run the code. The output is displayed as shown below:

#### Example #2

Here, you will see an example of how to find the sum of two disjointed ranges together. Suppose you have two separate bills for electricity and utilities. You want to find the total amount to be paid. Both being in different ranges isn’t a problem when using the VBA Sum formula.

**Step 1: **Format the specific cells to currency (USD, etc.) Right-click on the cells and select “Format Cells.”

**Step 2: **In the popup, select “Currency” in the categories and select “$ English (United States).”

**Step 3: **Go to the VBA Editor and name the subroutine to print the total cost.

**Step 4: **Define a Range variable and initialize it with the range of the first table, or the “Electricity” table.

**Step 5: **Similarly, declare a Range variable to store the second range.

**Step 6: **Call the VBA Sum formula and add the two ranges as the argument in the Sum function. Print the result in cell “D13.”

**Code:**

**Sub SumOfMultipleRanges()**

** Dim rng1 As Range**

** Set rng1 = Range(“C2:C11”)**

** Dim rng2 As Range**

** Set rng2 = Range(“E2:E11”)**

** Range(“D13”) = WorksheetFunction.Sum(rng1, rng2)**

**End Sub**

**Step 7: **Click the green arrow button when you want to run the code. Go back to the worksheet after running the subroutine.

#### Example #3

Using the VBA Sum formula, you can not only find the sum of a specific range but also the sum of an entire row or column. You can see it in this example.

**1. **Suppose you have a lot of values in the column “I,” and you don’t know the size of the range; you can sum the entire row instead.

**Step 1: **Define a subroutine to find the sum of the entire column.

**Step 2: **Print the sum value in cell “N8.” Specify the worksheet if you have multiple ones. To use the entire column, use “I:I” as an argument in the VBA Sum formula.

**Step 3: **Print the value in cell “N8” in a MsgBox function.

**Code:**

**‘Entire column**

**Sub ColSum()**

** ThisWorkbook.Sheets(“Sheet1”).Range(“N8”) = WorksheetFunction.Sum(Range(“I:I”))**

** MsgBox “The sum of column I is: ” & ThisWorkbook.Sheets(“Sheet1”).Range(“N8”).Value, vbInformation**

**End Sub**

**Step 4: **Run the above subroutine to print the sum value in the specified cell and a Message Box.

**2. **Similarly, suppose you have a set of values in a row that cannot be quantified, you can use the VBA Sum function to find the sum of the entire row using the Worksheet function ‘SUM.’

**Step 1: **To start with finding the sum of an entire row, name the subroutine appropriately.

**Step 2: **Define a Double variable to store the sum value after adding the values of an entire row. To call an entire row, you use the row number in the beginning and the end of the range; this makes it so that the entire row is calculated, as shown.

**Note: **Calling an integer variable may cause overflow errors in VBA. For larger values, use the Double datatype.

**Step 3: **Print the sum of the entire row in a Message Box function.

**Code:**

**Sub FullRowSum()**

** Dim rSum As Double**

** rSum = WorksheetFunction.Sum(Range(“16:16”))**

** MsgBox “The sum of row 16 is: ” & rSum, vbInformation**

**End Sub**

**Step 4: **The subroutine is run to find the sum of the entire row.

#### Example #4

Consider an example where you have an array of variables. You want to find their sum and print it. This can be done by calling the Sum function in Excel VBA.

**Step 1: **Start by naming the subroutine to find the sum of all elements in an array.

**Step 2: **Initialize an integer array and its size.

**Step 3: **Populate the empty array with values.

**Step 4: **Call the VBA Sum function for the array and print it in a Message box.

**Code:**

**Sub FullRowSum()**

** Dim rSum As Double**

** rSum = WorksheetFunction.Sum(Range(“16:16”))**

** MsgBox “The sum of row 16 is: ” & rSum, vbInformation**

**End Sub**

**Step 5: **Run the above subroutine to find the sum of the array.

#### Example #5

Suppose you have two tables in Excel. In a shop, when you buy an item, there are extra delivery fees. Depending on the corresponding product and the overhead prices, you are supposed to find the sum of each bill for different overhead prices for easier tracking.

In this example, there are 2 overhead charges, 300 and 400. You need to sum the corresponding values separately and print them on the sheet. For this example, instead of using the Sum function, you can use the VBA SumIF function.

**Step 1: **Define a subroutine to find the sum of a range with specifications.

**Step 2: **Define the first range variable to store the first sum (with 300).

**Step 3: **Find the sum of both the ranges. Here, the specification is that only the values with 300 are taken from column ‘A’ and added to column ‘C’.

**Step 4: **Similarly, set another range to print the sum (for overhead charges of 400).

**Step 5: **Like Step 3, call the SUMIF function and set it so that only values equal to 400 are taken from column ‘A’ and added with the adjacent values from column ‘C.’

**Step 6: **Print both the sums in a message box. For improved readability, print both answers in different lines using vbCrLf, which is a constant in Excel VBA used to print a new line.

**Code:**

**Sub CriteriaRange()**

** Dim sumRng As Range**

** Set sumRng = ThisWorkbook.Sheets(“Sheet3”).Range(“F7”)**

** sumRng = WorksheetFunction.SumIf(Range(“A1:A10”), 300, Range(“C1:C10”))**

** Dim sumRng2 As Range**

** Set sumRng2 = ThisWorkbook.Sheets(“Sheet3”).Range(“F12”)**

** sumRng2 = WorksheetFunction.SumIf(Range(“A1:A10”), 400, Range(“C1:C10”))**

** MsgBox “The price with $300 tax for each object: ” & sumRng.Value & vbCrLf & _**

** “The price with $400 tax for each object: ” & sumRng.Value, vbInformation**

**End Sub**

**Step 7: **Run the subroutine to print the answers in the worksheet and print it in a message box.

With this, you’ve successfully found the sums of multiple ranges based on user-defined criteria.

### Important Things To Note

- Ensure that the ranges provided to the Sum function are correctly specified and do not contain any errors.
- Consider using named ranges in VBA for better readability and maintenance of your code.
- Check for potential errors or edge cases in your data before applying the Sum function.
