Whether you’re a spreadsheet novice or a seasoned pro, this guide will equip you with the knowledge and skills to harness the power of the SUM function, ensuring your spreadsheets are not just organized but also mathematically sound.

Understanding the SUM Function

The SUM function is a fundamental tool in Excel used to calculate the sum of a range of cells. It is a versatile function that can be applied to various data types, making it essential for performing basic and complex calculations in spreadsheets.

Basic Usage and Syntax

The basic syntax of the SUM function is:“`=SUM(range)“`where “range” represents the cells or range of cells you want to add together. For example, to sum the values in cells A1 to A10, you would use the following formula:“`=SUM(A1:A10)“`


The SUM function accepts a single argument, which is the range of cells to be summed. This range can be specified as a continuous range (e.g., A1:A10), a non-continuous range (e.g., A1, A3, A5), or a combination of both. Additionally, the SUM function can be nested within other functions to perform more complex calculations.

Summing a Range of Cells

How to sum in excel

To sum a range of adjacent cells, use the SUM function followed by the range of cells you want to add together. For example, to sum the values in cells A1 to A10, you would enter the following formula in any empty cell:

Selecting the Cell Range

To select a range of cells, click on the first cell and drag the cursor to the last cell in the range. The selected cells will be highlighted in blue.

Entering the Formula

To enter the formula, type the following into the formula bar:


Press Enter to calculate the sum. The result will appear in the cell where you entered the formula.

Absolute and Relative Cell References, How to sum in excel

When using cell references in formulas, it’s important to understand the difference between absolute and relative references. Absolute references always refer to the same cell, even if the formula is copied to another location. Relative references change when the formula is copied, adjusting to the new location.

In the example above, the cell references are relative. If you copy the formula to another cell, the range will adjust to the new location. For example, if you copy the formula to cell B1, it will become:


Summing Cells with Criteria

Conditional summing allows you to calculate the sum of cells that meet specific criteria. Excel provides the SUMIF function for this purpose.The SUMIF function takes three arguments:

  • Range:The range of cells you want to sum.
  • Criteria:The condition that the cells must meet.
  • Sum_range:The range of cells you want to sum if the criteria is met.

For example, the following formula sums the values in the range A1:A10 if the corresponding cells in the range B1:B10 contain the text “Yes”:

=SUMIF(B1:B10, “Yes”, A1:A10)

You can use a variety of criteria operators to filter the cells. Some common operators include:

  • =: Equal to
  • <>: Not equal to
  • >: Greater than
  • <: Less than
  • >=: Greater than or equal to
  • <=: Less than or equal to

The SUMIF function is a powerful tool for conditional summing. It can be used to calculate the sum of cells that meet any number of criteria.

Summing Across Multiple Ranges

SUMIFS Function for Multiple Criteria

The SUMIFS function in Excel allows you to sum values across multiple ranges based on multiple criteria. It’s useful when you need to calculate the total of specific values that meet multiple conditions.

Syntax and Structure

The syntax of the SUMIFS function is:“`=SUMIFS(sum_range, criteria_range1, criteria1, [criteria_range2, criteria2], …)“`*


The range of cells containing the values you want to sum.

  • -*criteria_range1

    The range of cells containing the first criterion.

  • -*criteria1

    The criterion you want to apply to the first range.

  • -*criteria_range2, criteria2, …

    Additional criteria ranges and criteria, up to a maximum of 127 criteria.


Suppose you have a table with sales data, including product categories, sales amounts, and regions. You want to calculate the total sales for products in the “Electronics” category in the “North America” region.You can use the following SUMIFS function:“`=SUMIFS(sales_amounts, product_categories, “Electronics”, regions, “North America”)“`This function will sum the values in the sales_amounts column for rows where the corresponding product_categories column contains “Electronics” and the regions column contains “North America”.

Formatting the Sum Result: How To Sum In Excel

The SUM function result can be formatted to enhance its readability and presentation. Excel offers various formatting options to customize the appearance of the sum result.

Number Formatting

Number formatting applies a specific format to numeric values. You can choose from a range of formats, including:


Displays numbers in their default format.


Adds commas as thousands separators.


Adds a currency symbol (e.g., $) to the sum result.


Converts the sum result to a percentage.To apply number formatting, select the sum result cell and click the “Number Format” drop-down in the “Home” tab. Choose the desired format from the options.

Currency Symbols

Currency symbols can be added to the sum result to indicate the currency unit. To add a currency symbol, select the sum result cell and click the “Currency Format” drop-down in the “Home” tab. Choose the desired currency symbol from the options.

Custom Formats

Custom formats allow you to create your own specific formatting rules. For example, you can create a custom format that displays the sum result with two decimal places and a trailing “Total” text.To create a custom format, click the “Custom Format” option in the “Number Format” drop-down.

Enter the desired format code in the “Format Code” field. For example, to display the sum result with two decimal places and a trailing “Total” text, use the following format code:“`

00 “Total”


Advanced SUM Function Techniques

How to sum in excel

The SUM function in Excel is a powerful tool for adding up values, but it can be even more versatile when combined with other functions. One such function is SUMPRODUCT, which allows you to perform complex calculations involving multiplication and summation.


The SUMPRODUCT function multiplies corresponding elements in two or more arrays and then adds the results. It is particularly useful when you need to perform calculations on ranges of cells that contain both numbers and text.


To multiply the values in range A1:A5 by the values in range B1:B5 and then sum the results, you can use the following formula:“`=SUMPRODUCT(A1:A5, B1:B5)“`This formula will return the sum of the products of the corresponding values in the two ranges.

For example, if A1 contains 2, A2 contains 3, B1 contains 5, and B2 contains 6, the formula will return 50 (2

  • 5 + 3
  • 6).

Benefits of SUMPRODUCT

* Can perform complex calculations involving multiplication and summation

  • Can handle arrays of data, including both numbers and text
  • Can be used to create dynamic formulas that automatically adjust to changes in the data

Limitations of SUMPRODUCT

* Can be computationally expensive for large datasets

Can be difficult to understand and debug
