The COUNTIFS function applies criteria to cells across multiple ranges and counts the number of times all criteria are met.
This video is part of a training course called Advanced IF functions.
Syntax
COUNTIFS(criteria_range1, criteria1, [criteria_range2, criteria2]…)
The COUNTIFS function syntax has the following arguments:

criteria_range1 Required. The first range in which to evaluate the associated criteria.

criteria1 Required. The criteria in the form of a number, expression, cell reference, or text that define which cells will be counted. For example, criteria can be expressed as 32, ">32", B4, "apples", or "32".

criteria_range2, criteria2, ... Optional. Additional ranges and their associated criteria. Up to 127 range/criteria pairs are allowed.
Important: Each additional range must have the same number of rows and columns as the criteria_range1 argument. The ranges do not have to be adjacent to each other.
Remarks

Each range's criteria is applied one cell at a time. If all of the first cells meet their associated criteria, the count increases by 1. If all of the second cells meet their associated criteria, the count increases by 1 again, and so on until all of the cells are evaluated.

If the criteria argument is a reference to an empty cell, the COUNTIFS function treats the empty cell as a 0 value.

You can use the wildcard characters— the question mark (?) and asterisk (*) — in criteria. A question mark matches any single character, and an asterisk matches any sequence of characters. If you want to find an actual question mark or asterisk, type a tilde (~) before the character.
Example 1
Copy the example data in the following tables, and paste it in cell A1 of a new Excel worksheet. For formulas to show results, select them, press F2, and then press Enter. If you need to, you can adjust the column widths to see all the data.

Formula 
Description 
Result 
=COUNTIFS(A2:A7,"<6",A2:A7,">1") 
Counts how many numbers between 1 and 6 (not including 1 and 6) are contained in cells A2 through A7. 
4 
=COUNTIFS(A2:A7, "<5",B2:B7,"<5/3/2011") 
Counts how many rows have numbers that are less than 5 in cells A2 through A7, and also have dates that are are earlier than 5/3/2011 in cells B2 through B7. 
2 
=COUNTIFS(A2:A7, "<" & A6,B2:B7,"<" & B4) 
Same description as the previous example, but using cell references instead of constants in the criteria.
