The 10 Basic Excel Formulas Everyone Needs to Know

Introduction:

Microsoft Excel is a powerhouse for data management, analysis, and visualization. To harness its full potential, it's crucial to grasp the fundamental formulas that underpin its functionality. In this article, I'll delve into 10 basic Excel formulas, providing detailed explanations and practical examples to help you become proficient in leveraging this versatile tool.

1. SUM Function:

The SUM function in Excel is a versatile and powerful tool used to quickly calculate the total of a range of values. It is commonly employed in various scenarios such as budgeting, financial analysis, and statistical calculations.

Formula: =SUM(range)

The SUM formula takes a specified range of cells and adds up all the numerical values within that range. The range can include a single column, row, or a combination of both.

Example: Consider the following table:

 To find the sum of the values in cells A1 to A10, you would use the SUM function as follows:

=SUM(A1:A10)

This formula adds up the values in cells A1 through A10. If A1 contains 5, A2 contains 10, A3 contains 15, and so on, the SUM function will calculate the total sum of these values. In this example, the formula would return the sum of 5 + 10 + 15 + 20 + 25 + 30 + 35 + 40 + 45 + 50, which is 275.

2. AVERAGE Function:

The AVERAGE function in Excel is a powerful tool for calculating the average (mean) of a range of numeric values. It's commonly used to find the central tendency of a dataset, providing a representative value for a set of numbers.

Formula: =AVERAGE(range)

The AVERAGE formula takes a specified range of cells and calculates the mean by summing up all the numeric values in that range and dividing the sum by the count of numbers.

Example: Consider the following data in a table:

To find the average of values in cells B1 to B5, you would use the AVERAGE function:

=AVERAGE(B1:B5)

In this example, if cells B1 through B5 contain the values 10, 20, 30, 40, and 50, the AVERAGE function will calculate the mean by adding up these values (10 + 20 + 30 + 40 + 50 = 150) and dividing by the count of numbers (5). Therefore, the average is 30.

3. MAX and MIN Functions:

The MAX and MIN functions in Excel are essential for quickly identifying the highest and lowest values within a specified range. These functions are commonly used in data analysis to find the maximum and minimum values in a dataset.

Formula (MAX): =MAX(range)

The MAX formula takes a specified range of cells and returns the largest value in that range.

Formula (MIN): =MIN(range)

The MIN formula takes a specified range of cells and returns the smallest value in that range.

Example: Consider the following data in a table:

To find the maximum value in cells C1 to C8, you would use the MAX function:

=MAX(C1:C8)

In this example, if cells C1 through C8 contain the values 15, 25, 10, 35, 20, 30, 40, and 5, respectively, the MAX function will return the largest value, which is 40.

Similarly, to find the minimum value in the same range, you would use the MIN function:

=MIN(C1:C8)

In this case, the MIN function will return the smallest value in the range, which is 5.

4. COUNT Function:

The COUNT function in Excel is a simple yet powerful tool for determining the number of cells within a specified range that contain numerical values. It is commonly used to count the data points or entries in a dataset.

Formula: =COUNT(range)

The COUNT formula takes a specified range of cells and returns the count of cells that contain numeric values.

Example: Consider the following data in a table:

To count the number of cells with values in the range D1 to D15, you would use the COUNT function:

=COUNT(D1:D15)

In this example, if cells D1 through D15 contain the values 10, 25, 15, 30, 40, 5, 50, 20, 45, 35, and some empty cells, the COUNT function will return the count of cells with numeric values, which is 10. The empty cells are not included in the count.

 5. IF Function:

The IF function in Excel is a versatile formula that allows you to perform logical tests and return different results based on whether the condition is true or false. This is particularly useful for creating dynamic and conditional calculations in your spreadsheets.

Formula: =IF(logical_test, value_if_true, value_if_false)

The IF formula evaluates a specified logical test. If the logical test is true, it returns the value specified in the "value_if_true" argument; otherwise, it returns the value specified in the "value_if_false" argument.

Example: Consider the following data in a table:

Now, if you want to create a column in which "Yes" is displayed if the value in column A is greater than 10 and "No" otherwise, you would use the IF function:

=IF(A1>10, "Yes", "No")

In this example, if cell A1 contains the value 5, the formula will return "No" because 5 is not greater than 10. If A2 contains the value 15, the formula will return "Yes" because 15 is greater than 10. This logic is applied for each row in column A based on the respective values.

6. VLOOKUP Function:

The VLOOKUP function in Excel is a powerful tool for searching and retrieving data from a table based on a specified lookup value. This function is particularly useful when you need to find information in a large dataset.

Formula: =VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])

• lookup_value: The value to search for in the first column of the table.
• table_array: The range that contains the data, including the column with the lookup values and the columns containing the data to be retrieved.
• col_index_num: The column number in the table from which to retrieve the data.
• range_lookup: A logical value (TRUE or FALSE) that indicates whether to find an exact or approximate match. If TRUE or omitted, VLOOKUP will look for the closest match. If FALSE, it will look for an exact match.

Example: Consider the following data in a table (A1:C5):

Now, if you want to find the occupation of a person whose name is in cell A2, you would use the VLOOKUP function:

=VLOOKUP(A2, A1:C5, 3, FALSE)

In this example, if cell A2 contains "Alice," the formula will search for "Alice" in the first column of the table (A1:C5) and return the corresponding value in the third column (C1:C5). Therefore, the result would be "Analyst."

  7. XLOOKUP Function:

The XLOOKUP function in Excel is a versatile and powerful lookup function that allows you to search a range or array, find the specified value, and return a corresponding result. Unlike HLOOKUP, XLOOKUP is not limited to horizontal lookups and offers a more flexible approach with advanced features.

Formula: =XLOOKUP(lookup_value, lookup_array, return_array, [if_not_found], [match_mode], [search_mode])

• lookup_value: The value to search for in the lookup_array.
• lookup_array: The range or array where the search will be conducted.
• return_array: The range or array from which to retrieve the result.
• if_not_found: (Optional) The value to return if no match is found.
• match_mode: (Optional) 0 for an exact match, -1 for less than, 1 for greater than, 2 for a wildcard match.
• search_mode: (Optional) 1 for first-to-last search, -1 for last-to-first search.

Example: Consider the following data in a table (A1:C5):

Now, if you want to find the role of a person whose name is in cell A5, you would use the XLOOKUP function:

=XLOOKUP(A5,A1:A5,C1:C5,FALSE)

In this example, if cell A5 contains "David," the formula will search for "David" in the lookup_array (A1:A5) and return the corresponding value from the return_array (C1:C5). Therefore, the result would be "Engineer."

 8. INDEX and MATCH Functions:

The combination of INDEX and MATCH functions in Excel provides a powerful and flexible way to retrieve data from a table. This approach is often used when VLOOKUP or HLOOKUP might be limiting, and it allows for both horizontal and vertical lookups.

Formula (INDEX): =INDEX(array, row_num, [column_num])

• array: The range of cells containing the data.
• row_num: The row number within the array from which to retrieve data.
• column_num: (Optional) The column number within the array. If omitted, only the row is considered. Formula (MATCH): =MATCH(lookup_value, lookup_array, [match_type])
• lookup_value: The value to search for within the lookup_array.
• lookup_array: The range of cells containing the values to be searched.
• match_type: (Optional) 0 for an exact match, 1 for less than, -1 for greater than. If omitted, it defaults to 1.

Example: Consider the following data in a table (A1:C5):

Now, if you want to find the occupation of "John," you would use the INDEX and MATCH functions:

=INDEX(C1:C5, MATCH("John", A1:A5, 0))

In this example, the MATCH function searches for "John" in the range A1:A5 and returns the row number where it finds a match. This row number is then used by the INDEX function to retrieve the corresponding value from column C. Therefore, the result would be "Manager."

 9. CONCATENATE Function:

The CONCATENATE function in Excel is used to combine or concatenate multiple text strings into a single text string. This is particularly useful when you want to merge data from different cells or add specific characters between them.

Formula: =CONCATENATE(text1, text2, ...)

text1, text2, ...: The text values or cell references you want to concatenate. You can include up to 255 arguments.

Example: Consider the following data in a table (A1:B1):

If you want to create a full name by combining the values in cells A1 and B1 with a space in between, you would use the CONCATENATE function:

=CONCATENATE(A1, " ", B1)

In this example, the CONCATENATE function takes the value in cell A1 ("John"), adds a space (" "), and then combines it with the value in cell B1 ("Doe"). The result would be a single text string, "John Doe." This is a simple way to concatenate text values from different cells and create a unified string.

 10. RANK Function:

The RANK function in Excel is used to determine the rank of a specified number within a given range. It assigns a rank based on the numeric value, indicating its position relative to other values in the range.

Formula: =RANK(number, ref, [order])

Number: The value for which you want to find the rank.

Ref: The range of numbers that contains the value.

Order: (Optional) A numerical value indicating the ranking order. 0 or omitted for descending order, 1 for ascending order.

Example: Consider the following data in a table (B2:B10):

If you want to calculate the rank of the value in cell B2 relative to the range B2:B10 in descending order, you would use the RANK function:

=RANK(B2, B2:B10, 1)

In this example, the formula will rank the value in cell B2 (25) in comparison to the values in the range B2:B10. The "1" in the formula indicates descending order. The result will be the position of the value 25 in the ordered list, and if there are ties (i.e., repeated values), they will be assigned the same rank, and the next rank will be skipped.
