Are complex Excel scenarios bogging you down? What if there was an easy way to handle them? Our beginner’s guide to the IF function in Excel can help speed up the process. This step-by-step guide is all you need to turn data confusion into logical solutions. (Includes practice worksheet.)

## What is Excel IF Function?

The **IF function** is one of the most straightforward and useful logical functions. It can fill cell items based on evaluating a condition, such as a cell’s content and logical operators. What’s appealing about the function is that it can be used with other functions to handle more complex scenarios. You might think of it as a formula building block, and you can find it in the **Logical** category.

The wizard-like dialog allows you to fill 3 **Function Arguments** or data elements, but you could use the formula bar once you master it. This is the easiest way to learn an Excel formula because you can see if it returns your expected result. For example, a line at the bottom left of the dialog reads “**Formula result =**.”

### Excel IF Function Arguments

Field | Definition |
---|---|

Logical_test | A test on a cell value that is either TRUE or FALSE. |

Value_if_true | The value Excel will put in a cell if the test is true. |

Value_if_false | The value Excel will put in a cell if the test fails. |

Despite not having Microsoft Excel, my parents routinely employed this type of IF logic when calculating my allowance. Their version read:

**IF** you *empty the garbage, mow the lawn, wash the dishes,* **AND** *walk the dog*, you **get your total allowance**.

And since I grew up in New England, this logic would change with the seasons to account for leaves and snow.

## Setting Up the IF Function

Although Excel can’t issue an allowance, it can calculate the amount using a **logic test** based on whether a cell met a formula condition.

For example, I could create a spreadsheet with the chores needed to get an allowance. A value would be applied toward the allowance if the chores were completed (TRUE situation). Nothing would be added if the chore wasn’t completed (FALSE situation).

These examples are noted by labels [1] and [2] in the screen snap below.

Using the example above, you might express the logic in the following way:

**IF** cell **B2 equals “Y”**, then use the **Rate **value from cell **C2** ($3.00) in **D2**.

**IF** cell **B2 does not equal “Y”**, then place 0 in cell **D2**.

As you can see in this example, the IF logical condition is **TRUE **or **FALSE**. And it pays to take out the garbage.

## Comparison Operators & Syntax

To help evaluate conditions, Excel uses a list of familiar operators. You probably know these as we probably used them in math class. These operators will be evaluated as logical “true” or “false”. In the table below, B2 and C2 in the Example column are cell references.

Operator | Example |

= (equals) | B2 = “YES” |

< (less than) | B2 < 12 |

> (greater than) | B2 > 112 |

<= (less than or equal to) | B2 <= 12 |

>= (greater than or equal to) | B2 >= 12 |

<> (not equal to) | B2 <> C2 |

## How To Enter IF Function Arguments (Step-by-Step)

- Click the spreadsheet cell where you wish to use the Excel formula.
- From the
**Formulas**tab, click**Insert function…** - In the
**Insert Function dialog**text box, type “**if**“.

On Office 365, there is now a **Logical **button on the **Formulas **tab. You can select **IF** from the drop-down menu.

- Make sure your cursor is in the
**Logical_test**text box. - Click the spreadsheet cell you wish to evaluate. Excel will fill in the cell reference such as “B2”.
- Add the equals sign
**=**and your desired value**in quotes**. For example =”Y”. - In the
**Value_if_true**field, type the value you want to be entered in your cell if B2 equals “Y”. In our example, I’ll click cell C3. - In the
**Value_if_false**: field, enter the value the cell should have if B2 does not have a “Y”. I’ll enter 0. I could leave it blank, but the cell would show “FALSE”. - Review the dialog to see if the
**Formula result=**value (label [1] below) is what you expect. If not, check to see if any errors show to the right of the fields (label [2] below).

- Click
**OK**. - Copy the formula to the other cells in your column.

Even though the **Value_if_false** field is optional, providing a value is best. Otherwise, Excel will use FALSE in the cell value.

## Excel IF Function With Numeric Values (Formula Example)

The above spreadsheet might have been Version 1 for my parents. A new incentive program would appear based on some parent/child negotiations and competitive neighborhood rates. I probably would’ve requested pay for partial chores. No doubt, my parents would counter with a penalty clause if something was less than half done.

Excel is flexible when it comes to IF statements and can evaluate more than a simple “Y” or “N.” For example, if we convert our previous **Done?** column to a **% Done** column with a number, we can accommodate these new requirements such as:

`=IF(B2>0.5,B2*C2,-C2)`

The new formula returns the allowance based on the % Done in Column B. If the chore completion number is greater than .5, a prorated amount is applied to the allowance.

A negative amount was applied to the allowance if the chore completion rate was .5 or below. Loosely translated, an “incomplete” performance costs money. You could also apply colors using conditional formatting.

## Excel IF Formula Troubleshooting Tips

The IF function doesn’t always work as expected for a couple of reasons.

**You don’t have quotes around a text string**. For example, you used B2=Y instead of B2=”Y”.**The quotes aren’t needed if you use the values TRUE or FALSE as Excel recognizes them.****You have a data type mismatch**. For example, your comparison operator was comparing a number in one cell, such as “twelve”, but the comparison cell had 12. However, Excel is forgiving if you evaluate number formats such as 1.5 versus $1.50.

As you’ve seen, this is a versatile and useful function. Once you know how to use the IF function in Excel, you’ll start using it in more scenarios. The two examples presented here were foundational. But you can use IF functions to handle other transactions, such as applying sales tax, stock values, and shipping charges, fixing Excel DIV 0 errors, or even nesting IF functions with Boolean logic.

And if you have kids, let them build the Excel spreadsheet and give them a bonus for using the IF function.
