SUM Syntax In Excel, Examples, Tips & Tricks and More

The SUM function in Excel is used to add up a range of cells and return the total.


The syntax for the SUM function is: =SUM(number1, [number2], ...)


The arguments for the SUM function are:

  • number1 (required): The first cell or range of cells to be added.

  • [number2], ... (optional): Additional cells or ranges of cells to be added.

Here's an example of how to use the SUM function: =SUM(A1:A5)


This formula will add up the values in cells A1 through A5 and return the total.

You can also use the SUM function to add up multiple ranges of cells by separating each range with a comma.


For example: =SUM(A1:A5, C1:C5)


This formula will add up the values in cells A1 through A5 and cells C1 through C5, and return the total.

Additionally, you can use the SUM function with other functions or formulas as an argument.


For example: =SUM(A1:A5) + SUM(C1:C5)


This formula will add up the values in cells A1 through A5 and cells C1 through C5, and then add the two totals together.


SUM Examples In Excel Here are a few examples of using the SUM function in Excel:

  • Basic SUM formula: Suppose you have a column of numbers in cells A1 through A5, and you want to add them up. To do this, you can use the SUM function like this:

=SUM(A1:A5)


This formula will add up all the values in cells A1 through A5 and return the total.

  • SUM formula with a range of cells and individual cells: Suppose you have a table of numbers in cells A1 through D5, and you want to add up the values in columns B and D. To do this, you can use the SUM function like this:

=SUM(B1:B5,D1:D5)


This formula will add up all the values in cells B1 through B5 and D1 through D5 and return the total.


You can also include individual cells in your SUM formula, like this:

=SUM(B1:B5,D1,D3,D5)


This formula will add up the values in cells B1 through B5, D1, D3, and D5 and return the total.

  • SUM formula with criteria: Suppose you have a table of sales data in cells A1 through C10, and you want to add up the total sales for a specific product. To do this, you can use the SUMIFS function like this:

=SUMIFS(C1:C10,A1:A10,"Product A")


This formula will add up all the values in cells C1 through C10 where the corresponding cell in column A is "Product A" and return the total.


These are just a few examples of how you can use the SUM function in Excel to add up values in your worksheet.


What Are Some Mistakes When Using SUM In Excel Here are some common mistakes to avoid when using the SUM function in Excel:

  1. Including non-numeric values: The SUM function only works with numeric values. If you include non-numeric values in your range, the function will return an error. Make sure to exclude any cells in your range that contain text or other non-numeric data.

  2. Using absolute references incorrectly: If you use absolute references ($ signs) incorrectly in your SUM formula, it can cause the function to return incorrect results. Make sure to use absolute references only where necessary and double-check that your references are correct.

  3. Forgetting to include all relevant cells: If you don't include all the cells you want to add up in your range, the SUM function will only add up the cells that are included. Double-check that your range includes all the cells you want to add up.

  4. Nesting SUM functions incorrectly: If you nest SUM functions incorrectly, it can cause your formula to return incorrect results. Make sure to follow the proper syntax for nested functions and double-check that your formula is working as expected.

  5. Using SUM instead of SUMIF or SUMIFS: If you need to add up values based on certain criteria, using the SUM function alone may not be sufficient. In this case, you should use the SUMIF or SUMIFS function instead. Make sure to use the correct function for your needs.

By avoiding these common mistakes, you can ensure that your SUM formulas in Excel are accurate and reliable.
