OR Function Excel: How To Use The OR Function With Examples In 2026

The OR function in Excel checks whether one or more logical conditions are true and returns TRUE when at least one condition is satisfied. It returns FALSE only when every condition is false. You can combine OR with IF, AND, COUNTIF, SUM, and other Excel functions to build flexible formulas for real world data analysis.

If you are searching for or function excel, you are most likely trying to understand how Excel evaluates multiple conditions in a formula. The OR function is a logical function designed for situations where several possible conditions can produce a TRUE result. For example, you might want to identify employees who work in either Sales or Marketing, find students who scored above a particular threshold in one of several subjects, or flag orders that meet at least one qualifying condition.

The basic formula is simple:

=OR(A1=”Yes”,B1=”Yes”)

Excel returns TRUE if either condition is TRUE. It returns FALSE when neither condition is TRUE.

The function becomes particularly useful when you combine it with IF. A formula such as =IF(OR(A2=”Paid”,B2=”Approved”),”Process”,”Hold”) allows a spreadsheet to make a decision based on multiple possibilities.

Understanding this distinction prevents a common Excel mistake: assuming that OR requires every condition to be satisfied. It doesn’t. If you need every condition to be true, the AND function is usually the better choice.

OR Function Excel: What Does It Do?

The OR function is a logical function in Microsoft Excel that tests multiple conditions and determines whether at least one of them is TRUE.

Its basic syntax is:

=OR(logical1, logical2, …)

Each argument represents a condition Excel can evaluate as TRUE or FALSE.

For example:

=OR(10>5,10<2)

The first condition is TRUE because 10 is greater than 5. The second condition is FALSE because 10 is not less than 2. Because at least one condition is TRUE, the OR function returns:

TRUE

Now consider:

=OR(10<5,10<2)

Both conditions are FALSE, so Excel returns:

FALSE

This simple principle is the foundation of the function.

OR function at a glance

A simple way to remember OR

Think of OR as offering several possible paths to TRUE.

If condition A is true, the result can be TRUE.

If condition B is true, the result can also be TRUE.

If both are true, the result is still TRUE.

Only when every condition is false does OR return FALSE.

That makes OR different from AND, where every condition must be true.

Quick recap

OR means at least one condition must be true.

OR returns TRUE when one or more logical tests are TRUE.

OR returns FALSE only when all supplied conditions are FALSE.

The function is especially useful inside IF formulas.

Is the OR Function a Grammar, Vocabulary, or Usage Issue?

Unlike ordinary word comparison searches, the phrase OR function Excel refers to a technical spreadsheet concept rather than a grammar distinction.

The word OR is a logical operator in everyday language, but Excel gives it a specific computational purpose.

In ordinary English, saying:

You can choose tea or coffee.

presents two alternatives.

Excel follows a similar idea. A formula using OR evaluates several alternatives and returns TRUE if at least one alternative meets the specified condition.

For example:

=OR(A2=”Approved”,A2=”Pending”)

This asks Excel whether A2 contains either Approved or Pending.

OR versus AND

The most important comparison is between OR and AND.

Suppose A1 contains 75 and B1 contains 30.

=OR(A1>50,B1>50) returns TRUE because A1 satisfies the condition.

=AND(A1>50,B1>50) returns FALSE because B1 does not satisfy it.

This difference is responsible for many incorrect spreadsheet formulas.

Formal versus casual usage

Excel formulas don’t have formal or casual forms in the same way natural language does. However, spreadsheet users often create formulas that are technically valid but unnecessarily complicated.

A clear formula is generally easier to maintain than a long collection of nested conditions.

For example:

=OR(B2=”Open”,B2=”Pending”)

is easier to understand than a complicated series of nested IF statements performing the same logical test.

Academic and professional usage

OR is common in education, business analysis, finance, research, inventory management, project tracking, and data reporting.

Students may use it to test whether a score meets one of several criteria.

Businesses may use it to identify customers who meet at least one eligibility requirement.

Analysts may use it to filter records based on multiple alternatives.

How to Use the OR Function in Excel

The simplest way to use OR is to compare values directly.

Suppose cell A2 contains a department name.

You want to check whether the employee belongs to Sales or Marketing.

Use:

=OR(A2=”Sales”,A2=”Marketing”)

If A2 contains Sales, Excel returns TRUE.

If A2 contains Marketing, Excel also returns TRUE.

If A2 contains Finance, Excel returns FALSE.

Workplace example

Imagine a worksheet containing employee departments.

You want to determine whether each employee belongs to either Sales or Marketing.

Use:

=OR(B2=”Sales”,B2=”Marketing”)

Sarah receives TRUE.

David receives FALSE.

Emma receives TRUE.

James receives FALSE.

This is useful when a report needs to identify employees from multiple departments without creating separate formulas for each department.

Academic example

Suppose students receive scores in Mathematics and English.

You want to know whether a student scored at least 80 in either subject.

Use:

=OR(B2>=80,C2>=80)

If a student scores 82 in Mathematics and 65 in English, the result is TRUE.

If the student scores 70 in Mathematics and 75 in English, the result is FALSE.

This approach is useful when one qualifying result is enough.

Technology example

Suppose a technical support worksheet tracks device status.

You want to flag a device if its status is either Offline or Error.

Use:

=OR(B2=”Offline”,B2=”Error”)

The formula returns TRUE for either condition.

This can help identify records requiring attention.

Usage recap

Use OR when several possible conditions can independently produce a TRUE result. If any one of those conditions is enough to qualify a record, OR is usually appropriate.

How to Combine OR With IF

OR becomes much more useful when paired with IF.

OR tells Excel whether at least one condition is true.

IF tells Excel what to do with that result.

For example:

=IF(OR(B2=”Sales”,B2=”Marketing”),”Eligible”,”Not Eligible”)

Excel first evaluates the OR function.

If B2 is Sales or Marketing, OR returns TRUE.

IF then returns Eligible.

If B2 contains another department, OR returns FALSE and IF returns Not Eligible.

Workplace example

A company may offer a benefit to employees in either Sales or Marketing.

Formula:

=IF(OR(B2=”Sales”,B2=”Marketing”),”Benefit Available”,”Not Available”)

This creates an easy automated classification.

Academic example

A school might consider a student eligible for an award if the student scores at least 90 in Mathematics or Science.

Formula:

=IF(OR(B2>=90,C2>=90),”Award Eligible”,”Not Eligible”)

This formula translates a simple policy into an automatic spreadsheet decision.

Technology example

A monitoring spreadsheet might label a server for review if it reports either Critical or Offline.

=IF(OR(B2=”Critical”,B2=”Offline”),”Review”,”Normal”)

This makes the spreadsheet easier to scan.

Why IF and OR work so well together

OR handles the logical question.

IF handles the resulting action.

This combination is one of the most practical ways to use logical functions in Excel.

When You Should NOT Use the OR Function

OR is powerful, but it isn’t the right tool for every logical test.

1. Do not use OR when every condition must be true

If all conditions must be satisfied, use AND.

For example:

=AND(B2>=50,C2>=50)

is appropriate when both scores must reach 50.

2. Do not use OR for simple arithmetic

If your task is merely adding numbers, use SUM or the addition operator.

OR is designed for logical evaluation.

3. Do not use OR when you need to count matching records

If your objective is to count cells meeting conditions, COUNTIF or COUNTIFS may be more suitable.

4. Do not use OR when you need to add values conditionally

SUMIF or SUMIFS can often perform that task more directly.

5. Do not confuse OR with Excel’s OR operator in ordinary formula design

Excel also allows logical comparisons such as TRUE and FALSE expressions, but the OR function provides a clear way to combine multiple logical tests.

6. Do not create unnecessarily repetitive formulas

If a formula becomes extremely long, consider whether a lookup table, helper column, or another Excel function would make the spreadsheet easier to understand.

7. Do not use OR when the conditions are mutually exclusive but require a different action

Sometimes several conditions may need different outputs. In that situation, nested IF, IFS, or lookup based logic may be more appropriate.

Common OR Function Mistakes and Decision Rules

Decision Rule Box

If at least one condition can make the result TRUE, use OR.

If every condition must be TRUE, use AND.

This rule solves most basic decisions about whether OR belongs in a formula.

OR Function With Numbers, Text, and Logical Tests

The OR function can evaluate many types of logical conditions.

Text comparison

=OR(A1=”Apple”,A1=”Orange”)

This checks whether A1 contains either Apple or Orange.

Numerical comparison

=OR(A1>100,B1<20)

This returns TRUE if either condition is satisfied.

Cell references

=OR(A1,B1,C1)

When supplied with logical values, OR can evaluate them directly.

For example, if A1 contains TRUE and B1 and C1 contain FALSE, the result is TRUE.

Logical expressions

You can also combine several types of tests:

=OR(A1=”Approved”,B1>=90,C1=”Priority”)

The result is TRUE if any one of the three conditions is satisfied.

This flexibility makes OR useful in spreadsheets containing mixed information.

OR Function Excel With AND

OR and AND can also be combined.

Consider a situation where an employee must work in either Sales or Marketing and have completed training.

A formula could be:

=AND(OR(B2=”Sales”,B2=”Marketing”),C2=”Complete”)

The inner OR asks:

Is the department Sales or Marketing?

The outer AND then asks:

Is that condition true and is training complete?

This creates a more sophisticated logical test.

Why nested logic matters

Real business rules rarely involve just one condition.

For example:

A customer may qualify if they are from one of two regions and have placed at least five orders.

A student may qualify if they scored highly in Mathematics or Science and have completed an assignment.

A device may need review if it is Offline or Critical and has been in that state for more than an hour.

Combining OR with AND lets Excel represent these rules more accurately.

OR Function Excel Versus IF

OR and IF perform different jobs.

OR answers a logical question.

IF chooses an outcome.

For example:

=OR(A1>50,B1>50)

returns TRUE or FALSE.

But:

=IF(OR(A1>50,B1>50),”Pass”,”Fail”)

returns a meaningful label.

This distinction matters when building readable spreadsheets.

If you only need to test a condition, OR may be enough.

If you need Excel to respond to the condition with text, numbers, or another calculation, combine OR with IF.

OR Function Excel and Modern Data Analysis

Excel remains widely used for reporting, budgeting, project management, customer analysis, inventory tracking, and operational workflows. Logical functions such as OR help users turn business rules into repeatable spreadsheet logic.

Modern Excel workbooks can contain large tables, formulas, filters, dashboards, and automated calculations. OR can serve as one component inside those systems.

For example, a sales dashboard might use OR to identify customers from selected regions.

A project tracker might use OR to flag tasks that are either overdue or blocked.

An inventory worksheet might use OR to identify products that are either out of stock or below a reorder threshold.

The function itself is simple, but its value increases when it becomes part of a larger logical structure.

OR with conditional formatting

OR can also support conditional formatting rules.

For example, a worksheet could highlight a row when a status is either Delayed or Cancelled.

A logical formula can identify the relevant records, while conditional formatting provides the visual signal.

This combination is particularly useful in dashboards and operational spreadsheets.

Two Practical Case Studies

Case Study One: Employee Eligibility

Imagine a company with 500 employees. A benefit applies to people working in either Sales or Marketing.

The department is stored in column B.

A basic formula is:

=OR(B2=”Sales”,B2=”Marketing”)

The formula can be copied down the worksheet to identify qualifying employees.

If the company later decides that only employees who have completed training qualify, the formula can become:

=AND(OR(B2=”Sales”,B2=”Marketing”),C2=”Complete”)

The logical structure mirrors the policy.

This reduces manual checking and makes the spreadsheet rule easier to audit.

Case Study Two: Inventory Monitoring

Imagine an inventory table with product status in column B and stock quantity in column C.

A product needs attention if it is marked Out of Stock or has fewer than 10 units available.

The formula can be:

=OR(B2=”Out of Stock”,C2<10)

The result identifies products that meet either warning condition.

A user could then combine the formula with IF:

=IF(OR(B2=”Out of Stock”,C2<10),”Restock”,”Normal”)

The spreadsheet now converts raw inventory information into an actionable recommendation.

These examples demonstrate an important principle: OR doesn’t have to perform the final action. It can act as the logical engine behind a larger formula.

Error Prevention Checklist

Always use OR when

☑ One condition is enough to produce a TRUE result.

☑ You are checking several possible values.

☑ A record can qualify through different alternatives.

☑ You need to identify whether at least one test is satisfied.

☑ You are building an IF formula with multiple possible qualifying conditions.

Do not use OR when

☑ Every condition must be true.

☑ You need to count matching records.

☑ You need to add values based on criteria.

☑ A lookup function would solve the problem more clearly.

☑ The formula has become so complicated that a different spreadsheet structure would be easier to maintain.

Quick memory trick

OR means one or more.

AND means all.

Remembering those two ideas will help you choose the correct logical function in most basic Excel situations.

Related Excel Concepts You Should Master

The OR function becomes much easier to understand when you also know several related Excel concepts.

1. AND function

AND returns TRUE only when all supplied conditions are TRUE.

2. IF function

IF returns one result when a condition is TRUE and another result when it is FALSE.

3. IFS function

IFS can evaluate several conditions and return a corresponding result.

4. COUNTIF function

COUNTIF counts cells that meet a specified condition.

5. COUNTIFS function

COUNTIFS counts records that satisfy multiple criteria.

6. SUMIF function

SUMIF adds values that meet a condition.

7. SUMIFS function

SUMIFS adds values that meet multiple criteria.

8. NOT function

NOT reverses a logical result. TRUE becomes FALSE, and FALSE becomes TRUE.

9. IFERROR function

IFERROR allows you to provide an alternative result when a formula produces an error.

10. Conditional formatting

Conditional formatting changes the appearance of cells when specified rules are satisfied.

Learning these tools together gives you a stronger foundation for spreadsheet logic than memorizing individual formulas in isolation.

FAQs

What is the OR function in Excel?

The OR function is a logical Excel function that tests multiple conditions. It returns TRUE when at least one condition is TRUE and returns FALSE when all conditions are FALSE.

How do I use the OR function in Excel?

Use the syntax =OR(logical1,logical2,…). For example, =OR(A1=”Yes”,B1=”Yes”) returns TRUE when either A1 or B1 contains Yes.

What is the difference between OR and AND in Excel?

OR returns TRUE when at least one condition is TRUE. AND returns TRUE only when every condition is TRUE.

How do I use OR with IF in Excel?

Place OR inside an IF formula. For example, =IF(OR(A1=”Yes”,B1=”Yes”),”Accept”,”Reject”) returns Accept when either condition is satisfied.

Can the OR function check text in Excel?

Yes. OR can evaluate text comparisons such as =OR(A1=”Sales”,A1=”Marketing”).

Can I use more than two conditions with OR?

Yes. OR can evaluate multiple logical conditions. For example, =OR(A1=”Red”,A1=”Blue”,A1=”Green”) checks three possible values.

Does OR return TRUE if all conditions are TRUE?

Yes. OR returns TRUE when one or more conditions are TRUE, so it also returns TRUE when every condition is TRUE.

Why does my OR formula return FALSE?

An OR formula returns FALSE when every condition it evaluates is FALSE. Check each comparison carefully, including spelling, quotation marks, cell references, and numerical operators.

Can OR and AND be used together?

Yes. You can nest OR inside AND or combine both functions to represent more complex rules. For example, =AND(OR(A1=”Sales”,A1=”Marketing”),B1=”Complete”) requires both the department condition and training condition to be satisfied.

What is the easiest way to remember OR in Excel?

Remember that OR means at least one. If any supplied condition is TRUE, OR returns TRUE. If you need every condition to be TRUE, use AND instead.

Conclusion:

The OR function Excel users rely on for logical testing is straightforward once its central rule becomes familiar: at least one condition must be TRUE.

Use OR when several alternatives can independently satisfy a requirement. Use AND when every condition must be satisfied. Combine OR with IF when you want Excel to produce a specific result instead of simply displaying TRUE or FALSE.

For example:

=OR(A1=”Sales”,A1=”Marketing”)

checks whether either department matches.

And:

=IF(OR(A1=”Sales”,A1=”Marketing”),”Eligible”,”Not Eligible”)

turns that logical test into a practical decision.

The function can work with text, numbers, comparisons, cell references, and more complex formulas. It becomes even more useful when combined with AND, IF, COUNTIF, SUMIF, conditional formatting, and other Excel tools.

If you remember only one rule, make it this: OR needs one qualifying condition, while AND needs every qualifying condition. That distinction will prevent many of the most common logical formula errors and give you a reliable foundation for building smarter Excel spreadsheets.
