How to Sum Range of Cells in Row Using Excel VBA (6 Easy Methods)

We’re going to show you 6 easy methods of using Excel VBA to sum the range of cells in a row. To demonstrate our methods, we’ve picked a dataset with 3 columns: “Fruit”. “March Sale”, and “April Sale”.

6 Ways to Sum Range of Cells in a Row Using Excel VBA

1. Using FormulaR1C1 Property to Sum Range of Cells

In the first method, we’re going to use R1C1-style notation inside a With Statement to create a VBA code to sum the range of cells in rows. We’re going to show the Total Sale for each Fruit in column E. That means, E5 = C5 + D5 and so on. We’ll do this in all of the methods with different VBA codes.

Steps:

• Firstly, press ALT + F11 to bring up the VBA Window.

Alternatively, you can do this from the Developer tab >>> select Visual Basic.

• Secondly, from Insert >>> select Module.

This will show the VBA Module window. We’ll type our code here.

• Thirdly, type the following code in the VBA Module.

Sub SumInRow()
Dim x, rTotal As Range
Set x = Range("B5:D" & Range("B" & Rows.Count).End(xlUp).Row)
Set rTotal = x.Offset(, 3).Resize(x.Rows.Count, 1)
With rTotal
    .FormulaR1C1 = "=SUM(RC[-2]:RC[-1])"
    .Value = .Value
End With
End Sub

• Then, Save the code.
• After that, click anywhere inside the code.
• Finally, press the Run button.

This will execute our code, and we’ll see the added values in column E.

2. Use of VBA Evaluate Function to Sum Range of Cells

In this method, we’re going to use the VBA Evaluate method to sum the range of cells in the rows. Moreover, we’ll use For Next Loop and manually type our data range in this code.

Steps:

• Firstly, as shown in method 1, bring up the VBA Module and type this code.

Sub SumInRowEvaluate()
Dim x As Range
Set x = Range("C5:D10")
For y = 1 To x.Rows.Count
    x.Rows(y).Cells(1, 3).Value = Evaluate("SUM(" & x.Rows(y).Address & ")")
Next y
End Sub

• Secondly, Save the Module and press the Run button.

Note: This time, we didn’t click inside our code, hence, the Macros dialog box will appear.

• Finally, select “SumInRowEvaluate” and press Run.

Thus, we’ll use VBA to sum the range of cells in rows.

3. Dynamic VBA Code to Find Output Location to Place Sum Automatically

In this section, we’ll not set our output location manually. We’re gonna use a dynamic code to look for our output cells. Here, we’ll use the “VBA Find method” to locate our output column.

Steps:

• Firstly, as shown in method 1, bring up the VBA Module and type this code.

Sub SumInRowDynamic()
Dim x As Long, y As Long
x = Rows(4).Find("Total Sale", , , 1).Column - 2
y = Cells(Rows.Count, 2).End(xlUp).Row
    With Range(Cells(5, x + 2), Cells(y, x + 2))
        .Formula = "=SUM(RC[-" & x & "]:RC[-1])"
        .Value = .Value
    End With
End Sub

• Secondly, Save the code.
• Thirdly, click anywhere inside the code.
• Finally, press the Run button.

This will execute our code, and we’ll see the added values in E5:E10. Moreover, this is what the final step should look like.

4. Sum Rows Based on the Dynamic Range of Columns and display the Formula

In this fourth method, we’re going to display the SUM formula in the cells after we execute our code. Without further ado, let’s jump into the action.

Steps:

• Firstly, as shown in method 1, bring up the VBA Module and type this code.

Sub SumRowShowFormula()
    Dim x As Long
    For x = 5 To Cells(Rows.Count, "B").End(xlUp).Row
        Cells(x, "E").Formula = Replace("=sum(C@:D@)", "@", x)
    Next
End Sub

• Secondly, Save the code.
• Thirdly, click anywhere inside the code.
• Finally, press the Run button.

This will execute our code, and we’ll see the added values in E5:E10. Moreover, we can see the SUM function if we, select any of the cells from the output.

5. Inserting VBA WorksheetFunction.Sum

In this section, we’ll use the WorksheetFunction object to call the Excel SUM function to add the range of cells in the row.

Steps:

• Firstly, as shown in method 1, bring up the VBA Module and type this code.

Sub SumRowWFunction()
    Dim x As Long
    For x = 5 To Cells(Rows.Count, "B").End(xlUp).Row
        Cells(x, "E") = WorksheetFunction.Sum(Range("C" & x & ":D" & x))
    Next
End Sub

• Secondly, Save and close the Module.
• Thirdly, from the Developer tab >>> select Macros.

The Macro dialog box will appear.

• Select “SumRowWFunction” from the list.
• Finally, press the Run button.

Thus, we’ve shown yet another code to add a range of cells in the row.

6. Find the Range of Cells to Sum in Row

For the last method, we need to define our starting row and use the Range Resize property. Everything else will be automatic in this code. Moreover, we’re fixing our Sheet name here.

Steps:

• Firstly, as shown in method 1, bring up the VBA Module and type this code.

Sub SumInRowsDynamicRange2()
Dim wSheet As Worksheet
Dim x As Long
Dim y As Long
Application.ScreenUpdating = False
Set wSheet = Sheets("dynamic2")
x = wSheet.Cells.Find(What:="*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious).Row
y = wSheet.Cells.Find(What:="*", SearchOrder:=xlByColumns, SearchDirection:=xlPrevious).Column
wSheet.Cells(5, y).Resize(x - 4).FormulaR1C1 = "=SUM(RC3:RC[-1])"
Application.ScreenUpdating = True
End Sub

• Finally, Save the Module and Run it.

In conclusion, we’ve achieved our goal of a sum range of cells in the row.
