Excel OFFSET Function Examples

Use the OFFSET function to refer to a range, based on a starting cell. For example, get the total sales for April-June (start in column 4, include 3 columns).

OFFSET Introduction

The OFFSET function can return a reference to a range. Enter the starting point, number of rows and columns to move from starting point, and how big a range to include (number of rows and columns)

In this video, you'll see four examples of how to use the OFFSET function. The written instructions are below the video.

OFFSET Warning

The OFFSET function is volatile, so it could slow down a workbook if used in too many cells.

Instead, you could use a non-volatile function, like INDEX, to return a reference.

OFFSET Function Syntax

The OFFSET function has five arguments: OFFSET(reference,rows,cols,height,width)

1. reference: a cell or range of adjacent cells.
2. rows: Rows to move from starting point; can be positive (below starting reference) or negative (above starting reference).
3. cols: Columns to move from starting point; can be positive (right of starting reference) or negative (left of starting reference)
4. height: If entered, number must be positive, and is number of rows in returned reference
5. width: If entered, number must be positive, and is number of columns in returned reference.

Sales for Selected Month

With the OFFSET function, you can return a reference to a range, based on a starting reference. In this example, we want the sales amount in cell G2:

• starting reference is cell C1
• number of rows to offset is entered in cell F2
• sales amount is in column C, so the number of columns to offset is zero
• height is 1 row
• width is 1 column

=OFFSET(C1,F2,0,1,1)

In cell H2, there is a similar OFFSET formula, to return the month name. The only difference is the column offset -- 1 instead of zero.

=OFFSET(C1,F2,1,1,1)

Note: The height and width arguments could be omitted, because we want a reference that is the same size as the starting reference. I used them in this example, to show how all the arguments work.

Sum a Specific Month

In this example, the OFFSET function returns a reference to the sales amounts for the selected month, and the SUM function returns the total for that range. In cell B10, the selected month number is 3, so the result is the total of the March sales.

• starting reference is A3:A6
• rows to offset is zero (you could omit the zero, for the same result)
• columns to offset is entered in cell B10
• height and width are omitted, because the reference should be the same size as the starting reference

=SUM(OFFSET(A3:A6,0,B10))

Create a Range Based on Count

You can also use the OFFSET function to create a dynamic range. In this example, I've created a name, MonthsList, with this formula:

=OFFSET('Ex03'!$C$1,0,0,COUNTA('Ex03'!$C:$C),1)

If another month is added to the list in column C, it will automatically appear in the data validation drop down list in cell F2, which uses MonthsList as its source.

Sum Specific Number of Months

In this final example, OFFSET is combined with SUM and COUNT, to show the total for the last n months. As new quantities are added, the formula result will automatically adjust to include the latest months. In cell E2, the number of months is 2, so the August and September amounts are summed.

• starting reference is cell C2
• number of rows to offset is calculated by counting numbers in column C, subtracting number in cell E3, adding 1
• quantity is in column C, so the number of columns to offset is zero
• height is entered in cell E3
• width is 1 column

=SUM(OFFSET(C2,COUNT(C:C)-E3+1,0,E3,1))
