 # 101 Most Popular Excel Formulas: Pro Version Last Updated on: 8th October 2023, 10:22 am

Microsoft Excel is an essential software that professionals across various fields use to accomplish various tasks ranging from simple data entry to complex computations and analysis.

One of the powerful and advantageous features of Excel is its capability to execute formulas that perform calculations, manipulate data, or even automate and control the spreadsheet itself.

This feature is fundamental to mastering Excel. Let’s delve into the 101 most popular Excel formulas, their usage, and other applications.

For the purpose of our discussion, we will group these formulas into different categories: mathematical, logical, text, date and time, lookup and reference, and financial formulas.

##### Mathematical Formulas:
• SUM: This formula is one of the most common Excel functions and is used to add the value of cells in the argument. Usage is `=SUM(A1:A5)`, adding up the values in cells A1 through A5.
• AVERAGE: This formula calculates the average of the selected range of cells. For example, `=AVERAGE(A1:A5)` gives the average of values in cells A1 to A5.
• MAX/MIN: The max and min functions help to find the highest and lowest values within a range respectively. For instance, `= MAX(A1:A5)` would return the highest value in cells A1 through A5.
##### Logical Formulas:
• IF: The IF formula checks whether a condition is met and returns a value if true and another value if false. `=IF(A1>5, "Greater", "Lesser")` would return “Greater” if A1 is more than 5 and “Lesser” otherwise.
• AND/OR: These two functions check for multiple conditions and return true or false respectively. `=AND(A1>5, A2<10)` would return true only if both conditions are met.
