# Tip: Suppress #DIV/0 errors in Excel with a formula

### Problem:

If you ever receive a `#DIV/0`

error in Excel that you expect to be there (i.e. calculating percentages from other data which may not have accumulated yet), you can suppress it by using an `IF`

statement in the formula.

Let’s say you have three columns – `A`

, `B`

, and `C`

. `C`

calculates the percentage of `B`

and `A`

(i.e `B/A`

), but if `A`

is 0 or empty, you’ll get the `DIV/0`

error which throws off formulas, coloring, highlighting, etc.

### Solution

Instead of `= B1/A1`

, do something along the lines of the following:

```
=IF(A1=0, 0, B1/A1) or:
=IF(A1=0, "", B1/A1)
```

This does a simple check first: If `A`

is zero, it will substitute a default value. Otherwise, your calculation will go on as planned.

I’ve used this tip many a time to help with the presentation of an Excel sheet.
