How to keep one variable constant with other one changing with row in excel

Question

Lets say I have one cell A1, which I want to keep constant in a calculation. For example, I want to calculate a value like this: ``` =(B1+4)/(A1) ``` How do I make it so that if I drag that cell to make a calculation across cells in many rows, only the B1 value changes, while A1 always references that cell, instead of going to A2, A3, etc.?

Accepted Answer

Use this form:

```
=(B0+4)/$A$0
```

The `$` tells excel not to adjust that address while pasting the formula into new cells.

Since you are dragging across rows, you really only need to freeze the row part:

```
=(B0+4)/A$0
```
