How to Sum Only Positive or Negative Numbers in Excel (Easy Formula)

When you work with numbers in Excel, you often need to conditional add the data.

One common example of this is when you have to sum the positive numbers in Excel (or only sum the negative numbers).

And this can easily be done using the in-built formulas in Excel.

In this tutorial, I will show you how to sum only positive or negative numbers in Excel using simple formulas.

So let’s get started!

SUM Positive Numbers Only

Suppose you have a dataset as shown below and you want to sum all the positive numbers in column B.

Dataset to sum only positive values

Below is  the formula that will do this:


SUMIF formula to sum only positive values

The above SUMIF formula takes three arguments:

  1. The first argument is the criteria range. This is where we will check for criteria and only add values that meet the criteria. In our example, this is B2:B8
  2. The second argument is the criteria itself. Since we only want to sum the positive numbers, this is “>0”. Remember that when you use an operator, it should be within double-quotes.
  3. The third argument has the actual range that you want to sum.

Note that with the SUMIF formula, the criteria range and the range of cells that you want to sum can be different. In our example, both the criteria range and the sum range is the same (B2:B8).

Since I only have one criterion in this case, I have used the SUMIF formula. In case you have multiple criteria to check you can use this SUMIFS formula in Excel.

SUM All Positive Numbers Greater than 100

In the previous example, we added all the cells that had a positive value. You can also use the SUMIF formula, so only at those specific cells that meet another criterion.

For example, in the below data set, I only want to add those cells where the value is greater than 100.

All I need to do is adjust the criteria so that instead of adding all the positive numbers it adds all the numbers that are greater than 100.

Below is the formula that would do this:

As you can see, all I’ve done is adjusted the second argument, which is the criteria argument.

Add All Numbers where Another Cell Value is Positive

In the above examples, we have used the SUMIF formula in which the ‘criteria range’ and the ‘sum range’ is the same.

But as I mentioned, you can have these as separate ranges as well.

So you can have a range of cells where you evaluate a criterion and then based on whether a cell meets the criteria or not, you can then add the value in a corresponding range.

Below I have a data set where I want to add or the cells where the growth is positive which is in column C.

Dataset to sum positive value based on another cell

Below is the formula that will add only those cells in column B, where the corresponding cell in column C has a positive value:


SUMIF formula to sum only positive values based on another cell value

Note that this is a similar formula as we had used above (with one change). Instead of having the same ‘criteria’ and ‘sum’ range, it’s different in this formula.

Pro tip: When you have specified the criteria range, you don’t need to specify the entire sum range. For example, the following formula will work just fine –  =SUMIF(C2:C6,”>0″,B2). Since C2:C6 is already specified, you don’t need to specify B2:B6. Only the first cell will do. The formula will automatically take the same size range starting from B2.

SUM Negative Numbers Only

Just like we did the sum of all the positive numbers, you can use a similar concept to sum only the negative values only.

Suppose you have the dataset as shown below and you want to sum only the negative numbers in column B.

Dataset to sum only positive values

Below is the formula to do this:


Formula to sum negative values

The above formula uses “<0” as the criteria (second argument), which only adds the negative numbers.

And you can use the same concepts shown earlier to add negative numbers below a specific number and can even have separate criteria and sum ranges.

So this is how you can use a simple SUMIF formula to add only the positive numbers or negative numbers in Excel.
