The difference between COUNTIFS and COUNTIF is that the COUNTIF function counts cells that meet a single criterion, while the COUNTIFS function can count cells with one or multiple criteria.

**Example**: You are working with a dataset with the first name in column A, the last name in column B, and the salary in column C.

**Formula 1:** To count how many people have the letters "en" in their first name and a salary less than $100,000.

=COUNTIFS(A2:A9,"**en**", C2:C9,"<$100,000")

There is one person having the letter "en" in the first name with an income of less than $100,000.

**Formula 2:** To count how many people have the letters "W" in their last name and a salary less than $90,000.

=COUNTIFS(A2:A9,"**W**", C2:C9,"<$90,000")

There is one person having the letter "W" in the last name with an income of less than $90,000.

**Notes: The COUNTIFS function**

**Formula:**

= COUNTIFS(Range 1, Criteria 1, Range 2, Criteria 2…)

**Explanations:**

– Range 1 is required, which is the first data range you need to count;

– Criteria 1 is required, which can be a number, a text string, an expression, or a cell reference;

– Range 2: is optional, which is the second data range that you need to count;

– Criteria 2: is optional, which can be a number, a text string, an expression, or a cell reference.

– You can add other range/criteria pairs but the maximum number of range/criteria pairs is 127.

**Cautions:**

Each range must have the same number of rows and columns as the first range criteria, otherwise, you will get the wrong result "#VALUE!".
