There are two types of cell references in Excel: relative and absolute. The difference between them manifests itself in the way they behave when being copied from one cell to another. The relative cell references will automatically adjust while copying, while the absolute cell references will remain unchanged.
All cell references are, by default, relative. In order to switch the reference type and make it absolute, all you need to do is to add a dollar sign ($) in the cell address in the formula. In this way, you can “block” the row, the column, or both:
|A1||Both column and row will adjust when copying. This is an example of relative cell references.|
|$A$1||The column and the row will not adjust when copying. They will always remain A1. This is an example of absolute cell references.|
|$A1||Only the column will not adjust when copying. We can call it a mixed cell reference.|
|A$1||Only the row will not adjust when copying. We can call it a mixed cell reference.|
