# OFFSET Function

The OFFSET function returns a value from a cell, or range of cells that are a specified number of rows and columns from another cell.

This function can be really useful for creating dynamic references for your formulas and charts. Here you can see a great example of OFFSET being used for a rolling chart.

The syntax for the OFFSET function is:

*=OFFSET(reference, rows, columns, [height], [width])*

Argument |
Purpose |
---|---|

reference |
The starting cell reference from which the offset will be applied |

rows |
The number of rows to offset from the |

columns |
The number of columns to offset from the |

height |
The height, in number of rows, of the returned range |

width |
The width, in number of columns, of the returned range |

## Returning a Value from a Cell

Take the example data below.

To return the value of £160 from cell E2, the following formula can be used.

=OFFSET(A1, 1, 4)

This will offset 1 row down and 4 columns across from cell A1

Although the numbers are typed into the OFFSET function here. They could be returned by other functions, or form controls for more impressive examples.

## Returning a Range using OFFSET

In addition to returning a value from a cell, OFFSET can also return a range of cells. This can be really useful, because it can be used to feed other functions such as SUM.

=SUM(OFFSET(A1, 1, 4, 5, 1))

This returns the result of £1720

It sums the Total column for all the products. The *height* and *width* arguments are used to select range E2:E6.

## Returning the Last Value in a List

A very useful example of using the OFFSET function is to return the last value in a column, or a row. For this, we can insert the COUNTA function into OFFSET for more dynamism.

Take the example data below. This show a list of stock checks. And we want to return the value from the most recent check.

The following formula could be used.

=OFFSET(B1,COUNTA(B:B)-1,0)

The COUNTA function is used for the *rows* argument to find the bottom of the column. This moves 9 rows from B1 so a 1 is subtracted to make it the last cell in the column (instead of the first cell after the list).
