In this section, we will show you two formulas of summing values without or with n/a in Excel. Supposing you have a range of data as below screenshot shown. For summing all values without or with n/a, please do as follows.

sample data

1. Select a blank cell, copy and paste the one of the below formulas into the Formula Bar:Formulas:

A: Sum without #n/a: =SUMIF(A2:C6,"<>#n/a") + Enter key

B: Sum with #n/a: =SUM(IF(ISNA(A2:C6),0,A2:C6)) + Ctrl + Shift + Enter keys together.

Notes:

1. A2:C6 is the range you will sum. You can change it as you need.

2. When using the first formula, all n/a cells in the range won’t be included in the summing, while using the second one, all n/a cells are included in the summing. But these two formulas will get the same summing result.
