Average last n values in a row
To average the last n values in a row you can use a combination of Excel AVERAGE, OFFSET and COUNT functions, using Excel and VBA
Example: Average last n values in a row
|
This formula averages the last n values from a specific row, using a combination of the Excel Average, OFFSET and COUNT functions. In this example the formula averages the last three values (the number is captured in cell I5 and referenced in the formula) in row 4.
Please note that if there is a blank cell or a non numeric value in the row the formula will take this cell into consideration and will apply a value of 0 against the cell. |
Sub Average_last_n_values_in_a_row()
'declare a variable
Dim ws As Worksheet
Dim ws As Worksheet
Set ws = Worksheets("Analysis")
'average the last three values in a row
ws.Range("J5") = Application.Average(Range("C4").Offset(0, Application.Count(Range("C4:G4")) - ws.Range("I5")).Resize(1, Range("I5")))
ws.Range("J5") = Application.Average(Range("C4").Offset(0, Application.Count(Range("C4:G4")) - ws.Range("I5")).Resize(1, Range("I5")))
End Sub
PREREQUISITES
Worksheet Name: Have a worksheet named Analysis.
First cell in range: If using the exact same VBA code, the first cell in a range needs to be ("C4").
Last n values: In this example we are referencing to a cell ("I5") that contains a number of the last n values to average. Therefore, if using the exact same VBA code you will need to capture a number of the last n values to average in cell ("I5").
Row Range: In this example the values that we are averaging are captured in range ("C4:G4"). Therefore, if using the exact same VBA code you will need to capture the values that you want to average in range ("C4:G4").

ADJUSTABLE PARAMETERS
Output Range: Select the output range by changing the cell references ("J5") in the VBA code to any cell in the worksheet, that doesn't conflict with the formula.
First cell in range: Select the first cell in a range (row) from which to average the last n values by changing the cell reference ("C4") in the VBA code to any cell that doesn't conflict with the formula.
Last n values: Select the last number of values that you want to average in the specified row by changing the cell reference ("I5") in the VBA code to any cell that contains the number and doesn't conflict with the formula. You can also enter the number directly in the VBA code, by replacing 'Range("I5")' with a number.
Column Range: Select the column range where the values are captured that you want to average by changing the range reference ("C4:G4").
Output Range: Select the output range by changing the cell references ("J5") in the VBA code to any cell in the worksheet, that doesn't conflict with the formula.

FORMULA
AVERAGE(OFFSET(first_cell,0,COUNT(range)-1,,-last_n_values))
AVERAGE(OFFSET(first_cell,0,COUNT(range)-1,,-last_n_values))
ARGUMENTS
first_cell: The first cell in a specific row from which to begin averaging the last n values.
last_n_values: A number that represents the last n values to be averaged.
range: A range of cells (in a single row) that captures the values from which you want to average the last n values.
first_cell: The first cell in a specific row from which to begin averaging the last n values.
last_n_values: A number that represents the last n values to be averaged.
range: A range of cells (in a single row) that captures the values from which you want to average the last n values.
ADDITIONAL NOTES
Note 1: If a blank cell or a non-numeric value is captured in the last n values to be averaged, the formula treats these the same as 0.
