Creating an Absolute Reference

In earlier lessons we saw how cell references in formulas automatically adjust to new locations when the formula is pasted into different cells.
Sometimes, when you copy and paste a formula, you don't want one or more cell references to change. Absolute reference solves this problem. Absolute cell references in a formula always refer to the same cell or cell range in a formula. If a formula is copied to a different location, the absolute reference remains the same.
An absolute reference is designated in the formula by the addition of a dollar sign ($). It can precede the column reference or the row reference, or both. Examples of absolute referencing include:
$A$2The column and the row do not change when copied.
A$2The row does not change when copied.
$A2The column does not change when copied.

To Create an Absolute Reference:
  • Enter the numbers you want to calculate (e,g., 34,567 in cell B2 and 1,234 in cell B3).
  • Then, create a simple formula (=B2+B3).

To create an absolute reference in the formula just created, insert a $ valuebefore the B (column reference) and 2 (row reference) in the reference to B2 so the new formula reads, (=$B$2+B3)

Copy and Paste the formula to another adjacent cell. The formula now includes an absolute reference to B2, (=$B$2+D3).
