## Introduction

The count and sum functions are the most commonly used functions in Excel. You can count and sum numbers using multiple criteria.

## SUM

To sum a range of cells, a complete column, or non-contiguous columns in Excel, use the SUM function. Combine the SUM function with other Excel functions to generate amazing SUM formulas.

Most of the time, you will use the SUM function to sum a range of cells in

Excel.

In Excel, the SUM function adds the numerical values in a range of cells. Type "=SUM" followed by the data to be summed. It is categorized under the Maths and Trigonometry function. Numbers, cell references, and ranges can all be used as input to the function.

For example,

cells A1, A2, and A3 contain 200, 400, and 600, respectively. The formula â€ś = SUM(A1:A3) â€ť adds the numbers of the cells A1 to A3. It returns 1200.

NOTE: The SUM formula immediately adjusts when a value is added or removed. Changes to an existing cell range are also included. In addition, the function ignores empty cells and text values.

### Syntax of the SUM Excel Function

number1: The first numerical value to be added.

number2: The second numerical value to be added and so on.

The argument â€śnumber1â€ť is required, whereas the following numbers (â€śnumber 2â€ť, â€śnumber 3â€ť, etc.) are optional.

### The number of ways to Enter the SUM Function in Excel

1. Write Manually

Type "=SUM" followed by the inputs to manually enter the SUM function.

2. Using the â€śmath & trigâ€ť option

• From the drop-down menu, select the SUM option as shown below.

• Enter the SUM function arguments in the "function arguments" dialogue box.
• To get the output, click "Ok."

2. Click "AutoSum" in the Home tab. Alternatively, hit the shortcut keys " Alt + = " simultaneously.

## Types of SUM Function in Excel

### Sum

To add a range of cells, use the SUM function as shown above.

### Sumif

Use the SUMIF function(two arguments) to sum cells based on a single criterion.

For example, sum the numbers from A1 to A3, which are greater than 300).

=SUMIF(A1:A3, â€ś>300â€ť)

### Sumifs

Use the SUMIFS function to sum cells based on multiple criteria.

For example, Letâ€™s add numbers with a circular shape and red-colored.

The first argument will be the range to sum(The C column).

=SUMIFS(C1:C4, A1:A4, â€śCircularâ€ť, B1:B4, â€śRedâ€ť)

## Examples

1. The SUM function can also be used to add an entire column or row.

For example, to sum the entire column A, use the formula-

=SUM(A: A)

2. Sum Non-contiguous Cells

To sum non-contiguous cells of a column, use any following formulas.

=SUM(A1, A3, A5)

OR

=SUM(A1+A3+A5)
