SIGN: Excel Formulas Explained

Are you tired of staring at a bunch of numbers in Excel without having the faintest idea of what they mean? Do you yearn to be a spreadsheet wizard, slinging formulas like a boss?

Well, buckle up, friends, because I'm about to take you on a wild ride through the wide world of Excel formulas. And trust me, it's going to be a wild ride. We're talking about everything from SUM and COUNT functions to VLOOKUP and nested IF statements. And it's all going to be explained in plain English...or at least, as plain as Excel formulas can be.

What Are Excel Formulas?

First things first: what exactly is an Excel formula? At its simplest, it's a set of instructions for Excel to follow. You input the formula into a cell, hit Enter, and Excel spits out an answer. Piece of cake, right?

The fun (and complexity) comes from the fact that Excel formulas can include all sorts of operations and functions. You can add, subtract, multiply, and divide with ease. You can also do more advanced tasks, such as searching through data, finding averages, or performing complex calculations.

At their most basic level, Excel formulas consist of two things: operands and operators.

  • Operands: These are the things that the formula operates on. They can be things like numbers, cell references, or named ranges.
  • Operators: These are the symbols and functions that tell Excel what to do with the operands. Examples of operators include +, -, *, /, and ().

For example, if you wanted to add two numbers together, you could use the + operator:


Excel would then return the answer 4.

The Basics: SUM, COUNT, and More

Now that we've got the basics down, let's talk about some of the most commonly used Excel formulas. These are the ones you'll likely use on a regular basis, so it's important to get them down pat.


First up: SUM. This handy function does exactly what you'd expect: it adds up a range of cells.

To use SUM, simply select the cells you want to add together, and then use the following formula:


Excel will then return the sum of all the selected cells.


Next on the list is COUNT. This function is used to count the number of cells in a range that contain numbers.

To use COUNT, select the range of cells you want to count, and then use the following formula:


Excel will then return the number of cells in the range that contain numbers.


Another common function is AVERAGE. As you might expect, this function calculates the average value of a range of cells.

To use AVERAGE, select the cells you want to average, and then use the following formula:


Excel will then return the average value of the selected cells.


MAX and MIN are two more functions that you'll likely use on a regular basis. MAX returns the highest value in a range of cells, while MIN returns the lowest.

To use MAX, select the cells you want to find the maximum value of, and then use the following formula:


Excel will then return the highest value in the selected cells. To use MIN, simply replace MAX with MIN in the formula.

Going Deeper: VLOOKUP and Nested IF Statements

Alright, we've covered the basics. Now it's time to get a little more advanced.


VLOOKUP is one of the most powerful functions in Excel, and it's used to search for a specific value in a column of data.

To use VLOOKUP, you'll need to have a table set up with your data. In our example, let's say we have a table of employees and their salaries, and we want to find out how much a specific employee makes.

First, we'll need to select the cell where we want the answer to appear. Then, we'll use the following formula:

=VLOOKUP("Employee Name", A1:B10, 2, FALSE)

Let's break down what this formula does:

  • "Employee Name": This is the value we want to look up in our table.
  • A1:B10: This is the range of cells that contains our table data.
  • 2: This tells Excel which column to return the value from (in this case, the salary column).
  • FALSE: This tells Excel that we want an exact match. If set to TRUE, Excel will return the closest match instead.

Excel will then search through the employee names in our table, find the matching name, and return that employee's salary. Pretty neat, huh?

Nested IF Statements

Last but not least, we've got nested IF statements. These can be a bit tricky to wrap your head around at first, but they're incredibly powerful.

IF statements allow you to perform a certain action based on whether a specific condition is true or false. For example, you could use an IF statement to check if a cell contains a certain value, and then perform an action if it does.

Nested IF statements take this one step further by allowing you to have multiple conditions. Let's take a look at an example:

=IF(A1="Yes", IF(B1>10, "Big success!", "Still pretty good"), "Maybe next time...")

Let's break down what this formula does:

  • The first IF statement checks if A1 equals "Yes".
  • If it does, the formula moves on to the second IF statement.
  • The second IF statement checks if B1 is greater than 10.
  • If it is, the formula returns "Big success!".
  • If it's not, the formula returns "Still pretty good".
  • If the first IF statement is false (i.e. A1 does not equal "Yes"), the formula returns "Maybe next time...".

And there you have it: a nested IF statement with multiple conditions. It may look a little intimidating at first, but once you get the hang of it, the possibilities are endless.

Wrapping Up

So there you have it: a whirlwind tour of some of the most commonly used Excel formulas. Whether you're a data analysis pro or a newbie to the world of spreadsheets, these formulas are sure to come in handy at some point. Happy formulating!
