COUNT and COUNTA functions to count cells in Excel

This tutorial provides a concise overview of Excel's COUNT and COUNTA functions, illustrating their use with practical examples. You'll also learn how to leverage COUNTIF and COUNTIFS for counting cells based on specific criteria.

Excel excels at numerical manipulation, but often requires counting cells containing values—any value, or specific value types. This might involve counting inventory items or list entries. Excel offers COUNT and COUNTA functions for this purpose.

Let's explore these core functions and then delve into formulas for counting cells meeting particular conditions, highlighting nuances in counting various value types.

Excel COUNT Function: Counting Numerical Cells

The COUNT function tallies cells containing numerical values. Its syntax is:

COUNT(value1, [value2], ...)

where value1, value2, etc., represent cell references or ranges. Excel 365-2007 supports up to 255 arguments; earlier versions handle up to 30.

For example, =COUNT(A1:A100) counts numeric cells in A1:A100. Importantly, dates and times (stored as serial numbers) are also counted.

Key COUNT Function Considerations:

1. For cell references/ranges, only numbers, dates, and times are counted. Blanks and non-numeric entries are ignored.
2. When directly inputting values, numbers, dates, times, TRUE/FALSE booleans, and numeric text (e.g., "5") are counted.

For instance, =COUNT(1, "apples", "2", 1/1/2016, TRUE) returns 4.

COUNT Function Examples:

• Counting numeric cells in a single range: =COUNT(A2:A10)
• Counting across multiple non-contiguous ranges: =COUNT(B2:B7, D2:D7)

Tips: Use COUNTIF or COUNTIFS for counting numbers meeting specific criteria. For counting cells with text, logical values, and errors, use COUNTA.

Excel COUNTA Function: Counting Non-Blank Cells

COUNTA counts cells containing any value (non-empty cells). Its syntax mirrors COUNT's:

COUNTA(value1, [value2], ...)

=COUNTA(A1:A100) counts non-empty cells in A1:A100. Multiple non-adjacent ranges are also supported: =COUNTA(B2:B10, D2:D20, E2:F10).

COUNTA counts: numbers, dates/times, text, TRUE/FALSE, error values, and even empty text strings (""). However, it does not count truly empty cells. Cells appearing empty but containing spaces or formulas returning "" will be counted.

The Excel status bar provides a quick count of non-blank cells in a selected range.

Advanced Cell Counting Techniques

Beyond COUNT and COUNTA, Excel offers functions for more complex counting scenarios.

Counting Cells Meeting One Condition (COUNTIF)

COUNTIF counts cells meeting a specified criterion:

COUNTIF(range, criteria)

=COUNTIF(A2:A15, "apples") counts "apples" in A2:A15. Cell references can also be used for the criteria.

Counting Cells Matching Multiple Criteria (COUNTIFS)

COUNTIFS extends COUNTIF to handle multiple ranges and criteria:

COUNTIFS(criteria_range1, criteria1, [criteria_range2, criteria2]...)

=COUNTIFS(A2:A15,"apples", B2:B15,">=200") counts "apples" with sales ≥ $200. Cell references can be used for criteria.

Determining Total Cells in a Range

Use ROWS and COLUMNS to find the total number of cells in a rectangular range:

=ROWS(range)*COLUMNS(range)

=ROWS(A1:D7)*COLUMNS(A1:D7) calculates the total cells in A1:D7.

This tutorial covers the fundamentals of Excel's COUNT and COUNTA functions, providing a solid foundation for efficient cell counting.
