Excel SUBTOTAL Function

last modified April 4, 2025

The SUBTOTAL function is a versatile Excel function that performs various calculations while ignoring hidden rows. It can calculate sums, averages, counts and more. This tutorial provides a comprehensive guide to using the SUBTOTAL function with detailed examples. You’ll learn basic syntax, practical applications, and advanced techniques to master this essential Excel function.

SUBTOTAL Function Basics

The SUBTOTAL function performs calculations on a range of data while optionally ignoring hidden rows. It offers 11 different operations through its function_num argument. The syntax is flexible and powerful.

Component
Description


Function Name
SUBTOTAL


Syntax
=SUBTOTAL(function_num, ref1, [ref2], ...)


Arguments
function_num (1-11 or 101-111), ref1 (required), ref2 (optional)


Return Value
Result of specified calculation on the range

This table breaks down the essential components of the SUBTOTAL function. It shows the function name, basic syntax format, argument details, and return value characteristics.

Basic SUBTOTAL Example (Sum)

This example demonstrates the simplest use of SUBTOTAL to sum a range of values.

A
B


10



20



30




=SUBTOTAL(9, A1:A3)

The table shows a simple spreadsheet with values in column A and a SUBTOTAL formula in cell B4 that sums the values from A1 to A3.

Basic SUBTOTAL sum formula

=SUBTOTAL(9, A1:A3)

This formula sums values in cells A1 through A3 using function_num 9 (SUM). The result will be 60 (10+20+30). This shows the basic summing capability of SUBTOTAL.

SUBTOTAL with Hidden Rows

SUBTOTAL can ignore values in hidden rows when using function numbers 101-111. This example shows this behavior.

A
B


10



20
(hidden row)


30




=SUBTOTAL(109, A1:A3)

This table demonstrates SUBTOTAL’s ability to ignore hidden rows in calculations. Row 2 is hidden, and the formula uses 109 (SUM ignoring hidden rows).

SUBTOTAL ignoring hidden rows

=SUBTOTAL(109, A1:A3)

This formula sums A1 (10) and A3 (30), ignoring the hidden A2 (20). The result is 40. This demonstrates SUBTOTAL’s unique ability to handle filtered data.

SUBTOTAL for Average Calculation

SUBTOTAL can calculate averages using function_num 1 or 101. This example shows average calculation while ignoring hidden rows.

A
B


10



20
(hidden row)


30




=SUBTOTAL(101, A1:A3)

The table shows how SUBTOTAL calculates averages while excluding hidden rows. Row 2 is hidden, and the formula uses 101 (AVERAGE ignoring hidden rows).

SUBTOTAL average calculation

=SUBTOTAL(101, A1:A3)

This formula averages A1 (10) and A3 (30), ignoring hidden A2 (20). The result is 20. This shows SUBTOTAL’s ability to perform different calculations.

SUBTOTAL for Count Operations

SUBTOTAL can count cells with numbers (function_num 2 or 102) or non-empty cells (function_num 3 or 103). This example demonstrates counting.

A
B


10



Text
(hidden row)


30




=SUBTOTAL(102, A1:A3)



=SUBTOTAL(103, A1:A3)

This table shows two counting operations: counting numbers and counting non-empty cells, both ignoring hidden rows. Row 2 is hidden and contains text.

SUBTOTAL count examples

=SUBTOTAL(102, A1:A3) // Count numbers, ignoring hidden =SUBTOTAL(103, A1:A3) // Count non-empty, ignoring hidden

The first formula counts numeric cells (A1 and A3), ignoring hidden A2. Result is 2. The second counts all non-empty cells (A1-A3), but still ignoring hidden A2. Result is 2 (A1 and A3).

SUBTOTAL with Multiple Ranges

SUBTOTAL can handle multiple ranges just like other Excel functions. This example shows summing across non-contiguous ranges.

A
B
C

20





=SUBTOTAL(9, A1:A2, B1:B2)

This table demonstrates SUBTOTAL’s ability to combine different ranges in one calculation. The formula sums values from both column A and column B ranges.

SUBTOTAL with multiple ranges

=SUBTOTAL(9, A1:A2, B1:B2)

This formula sums all values in ranges A1:A2 (5+15) and B1:B2 (10+20). The result is 50. This shows SUBTOTAL’s flexibility with multiple input ranges.

SUBTOTAL with Filtered Data

SUBTOTAL is particularly useful with filtered data as it automatically ignores hidden (filtered-out) rows when using 101-111 function numbers.

A
B
C


100
North



200
South
(filtered out)


300
North





=SUBTOTAL(109, A1:A3)

The table shows data filtered to show only “North” region sales. The SUBTOTAL formula with 109 sums only visible (unfiltered) rows.

SUBTOTAL with filtered data

=SUBTOTAL(109, A1:A3)

This formula sums only visible cells in A1:A3 (100 and 300), ignoring filtered A2 (200). The result is 400. This automatic handling makes SUBTOTAL ideal for filtered reports.

SUBTOTAL Nested in Other Calculations

SUBTOTAL results can be used in other calculations. This example shows calculating a percentage of subtotal.

A
B
C


100
North



200
South
(filtered out)


300
North





=A1/SUBTOTAL(109, A1:A3)

The table demonstrates using SUBTOTAL within a larger calculation. The formula calculates what percentage the first row is of the filtered total.

SUBTOTAL in percentage calculation

=A1/SUBTOTAL(109, A1:A3)

This formula divides A1 (100) by the filtered sum of A1:A3 (400). The result is 0.25 or 25%. This shows how SUBTOTAL can be part of more complex formulas.

Common SUBTOTAL Use Cases

Here are some practical scenarios where SUBTOTAL shines:

• Dynamic Reports: Create summary calculations that automatically adjust when filtering data

• Data Analysis: Analyze visible data while ignoring filtered-out values

• Dashboard Summaries: Build flexible dashboard metrics that respond to filters

• Sub-Reports: Calculate totals within filtered sections of larger datasets

Tips and Best Practices

To get the most out of SUBTOTAL, consider these tips:

• Use 101-111 function numbers when working with filters or hidden rows

• Avoid nesting SUBTOTAL within another SUBTOTAL (it can cause errors)

• Combine with AutoFilter for interactive reports

• Use with tables for structured references

• Test formulas with both hidden and visible data to verify results

Limitations

While powerful, SUBTOTAL has some limitations to be aware of:

• Ignores manually hidden rows only with 101-111 function numbers

• Doesn’t work with 3D references across multiple sheets

• Can’t directly handle array constants

• May return errors if ranges include other SUBTOTAL formulas

The SUBTOTAL function is an essential tool for dynamic reports and filtered data analysis in Excel. Its ability to ignore hidden rows makes it superior to regular functions like SUM or AVERAGE for many tasks. By mastering SUBTOTAL, you can create flexible, robust spreadsheets that automatically update calculations when data is filtered or rows are hidden. Whether you’re building dashboards, analyzing datasets, or creating interactive reports, SUBTOTAL provides the versatility needed for professional Excel work.
