This tutorial will show you how to use the Excel SUMIF and SUMIFS Functions in VBA.
VBA does not have an equivalent of the SUMIF or SUMIFS Functions that you can use – a user has to use the built-in Excel functions in VBA using the WorksheetFunction object.
The WorksheetFunction object can be used to call most of the Excel functions that are available within the Insert Function dialog box in Excel. The SUMIF function is one of them.
Sub TestSumIf() Range("D10") = Application.WorksheetFunction.SumIf(Range("C2:C9"), 150, Range("D2:D9")) End Sub
The procedure above will only add up the cells in Range(D2:D9) if the corresponding cell in column C = 150.
Assigning a SUMIF result to a Variable
You may want to use the result of your formula elsewhere in code rather than writing it directly back to an Excel Range. If this is the case, you can assign the result to a variable to use later in your code.
Sub AssignSumIfVariable() Dim result as Double 'Assign the variable result = WorksheetFunction.SumIf(Range("C2:C9"), 150, Range("D2:D9")) 'Show the result MsgBox "The total of the result matching the 150 sales code is " & result End Sub
The SUMIFS function is similar to the SUMIF WorksheetFunction but it enables you to check for more than one criteria. In the example below, we are looking to add up the sale price if the sale code is 150 AND the Cost Price is greater than 2. Notice that in this formula, the range of cells to add up is in front of the criteria, whereas in the SUMIF function, it is behind.
Sub MultipleSumIfs() Range("D10") = WorksheetFunction.SumIfs(Range("D2:D9"), Range("C2:C9"), 150, Range("E2:E9"), ">2") End Sub
Using SUMIF with a Range Object
You can assign a group of cells to the Range object, and then use that Range object with the WorksheetFunction object.
Sub TestSumIFRange() Dim rngCriteria As Range Dim rngSum as Range 'assign the range of cells Set rngCriteria = Range("C2:C9") Set rngSum = Range("D2:D9") 'use the range in the formula Range("D10") = WorksheetFunction.SumIf(rngCriteria, 150, rngSum) 'release the range objects Set rngCriteria = Nothing Set rngSum = Nothing End Sub
Using SUMIFS on Multiple Range Objects
Similarly, you can use SUMIFS on multiple Range Objects.
Sub TestSumMultipleRanges() Dim rngCriteria1 As Range Dim rngCriteria2 as Range Dim rngSum as Range 'assign the range of cells Set rngCriteria1= Range("C2:C9") Set rngCriteria2 = Range("E2:E9") Set rngSum = Range("D2:D9") 'use the ranges in the formula Range("D10") = WorksheetFunction.SumIfs(rngSum, rngCriteria1, 150, rngCriteria2, ">2") 'release the range object Set rngCriteria1 = Nothing Set rngCriteria2 = Nothing Set rngSum = Nothing End Sub
Notice that because you are using a greater than sign, the criteria greater than 2 needs to be within quotes.
When you use the WorksheetFunction.SUMIF to add a sum to a range in your worksheet, a static sum is returned, not a flexible formula. This means that when your figures in Excel change, the value that has been returned by the WorksheetFunction will not change.
In the example above, the procedure has added up Range(D2:D9) where the SaleCode equals 150 in column C, and the result was put in D10. As you can see in the formula bar, this result is a figure and not a formula.
If any of the values change in either Range(D2:D9) or Range(C2:D9), the result in D10 will NOT change.

The formula method allows you to point specifically to a range of cells eg: D2:D10 as shown below.
Sub TestSumIf() Range("D10").Formula = "=SUMIF(C2:C9,150,D2:D9)" End Sub
The FormulaR1C1 method is more flexible in that it does not restrict you to a set range of cells. The example below will give us the same answer as the one above.
Sub TestSumIf() Range("D10").FormulaR1C1 = "=SUMIF(R[-8]C[-1]:R[-1]C[-1],150,R[-8]C:R[-1]C)" End Sub
However, to make the formula more flexible, we could amend the code to look like this:
Sub TestSumIf() ActiveCell.FormulaR1C1 = "=SUMIF(R[-8]C[-1]:R[-1]C[-1],150,R[-8]C:R[-1]C)" End Sub
Wherever you are in your worksheet, the formula will then add up the cells that meet the criteria directly above it and place the answer into your ActiveCell. The Range inside the SUMIF function has to be referred to using the Row (R) and Column (C) syntax.
Both these methods enable you to use Dynamic Excel formulas within VBA.
There will now be a formula in D10 instead of a value.
