Excel Formula Meaning of $

Question

what the meaning of this formula?

=B9/$G$3

Actually i didn't understand what the meaning of $ sign.

Answer 1

It's an absolute reference: it means don't treat this as a relative reference if you copy / paste. If you copy that into the cell below to it, you'll get

=B10/$G$3

i.e. Excel has automatically updated the row in the formula for the new location of B9->10, but left G3 alone - i.e. it's a constant you've set once that you want to apply to all rows or cells in a table.

Answer 2

The $ tells Excel not to change the number / character that comes after it when you extend the selection.

If you put that formula in D5, then fill it down to E5, it will become C9/$G$3.
The G doesn't change to H because the $ tells it not to.
