How to prevent cell reference in a formula from incrementing /changing in Excel?

To calculate each number’s percentage of their total, you need to keep the totals (SUM(A2:A15)) static in your formula =A2/SUM(A2:A15). You can do as follows:

In the Cell B2, change your formula with adding absolute reference signs “$” to your formula as =A2/SUM($A$2: $A$15), and then drag the Fill Handle down to other cells.

Note: You can click on the reference cell in the Formula Bar, and then press the F4 key to add $ signs to this reference cell in the formula.

Now the absolute reference SUM($A$2: $A$15) is not incrementing when filling down. See screenshot:

Note: If you have many formulas to fill down, you have to change each formula one by one.

This method will introduce Kutools for Excel’s Convert Refers utility to prevent cell references in many formulas from incrementing easily.

1. Select the formula cells whose references you will prevent from incrementing, and click Kutools > More > Convert Refers

2. In the opening Convert Formula References dialog box, check the To absolute option, and click the Ok button.

Then all selected formula cells’ references are changed to absolute reference as below screenshot shown:

3. Select the formula cells, and drag their Fill Handle down to other cells.

So far, in each column formulas return the same value when filling down, because cell reference is static without incrementing. See screenshot:

Kutools for Excel's Convert Refers utility is designed to help Excel users convert cell references of multiple formulas between absolute reference and relative reference with only several clicks.
