We’ve previously established what are the rules of writing criteria in the SUMIFS function:

- we can reference any cell
- we can enter any number directly in the function
- we can enter text directly in the function, nested inside of quotation marks [“”]
- logical test is nested inside of quotation marks [“”], with comparison operator coming first and a number second.

The story however does not end there, and advanced users can do even more with the SUMIFS function.

We can nest formulas in the SUMIFS function criteria with the help of the parenthesis [()].

Consider the following example:

We have a list of numbers from 1 to 100, and we want to SUM the numbers that are equal to 6. Instead of just writing 6 in the criteria, we can also nest formula between parenthesis. The SUMIFS function is returning the sum of all the numbers in the column A equal to 6 – just one in this example.

Another thing we can do is to nest a function in the criteria:

In this example, the SUMIFS function is returning the sum of all the numbers in the column A equal to the smallest number, 1.

These principles become obviously useful when combined with conditional statements.

Logical test is usually nested inside of quotation marks [“”], with comparison operator coming first and a number second. However, this will not work with formulas and functions as they will be treated as text and not calculated.

**In order to combine logical test with formulas and functions we first have to nest logical operator inside of quotation marks [“”], use ampersand [&], and only then write our function or formula.**

We could write a formula that will sum only numbers smaller than 6 in this way:

We would return 15, as that is the sum of numbers smaller then 6, cells A1 to A5.

We could write a formula that will sum only numbers smaller than average in this way:

We would return 1275, as our average is 50,5 and with the given criteria, our formula will only sum the numbers smaller than that number, cells A1 to A50, returning 1275.

What if we want to only sum the numbers below the 10th percentile – i.e. 10% of the lowest values?

We would use this formula:

=SUMIFS(A:A;A:A;”<“&PERCENTILE.INC(A:A;0,1))

What if we want to only sum the numbers between the 10th percentile and 20th percentile?

We could sum the values below the 20th percentile and subtract the sum of the values below the 10th percentile, like this:

=SUMIFS(A:A;A:A;”<“&PERCENTILE.INC(A:A;0,2))-SUMIFS(A:A;A:A;”<“&PERCENTILE.INC(A:A;0,1))

This is how the returns would look like:

Naturally, if we want to sum the numbers above a certain average or percentile, we can use greater than [>] operator.

These are Comparison operators available, and can all be nested in the SUMIFS criteria:

Operator |
Description |

= | equal to |

> | greater than |

>= | greater than or equal to |

< | less than |

<= | less than or equal to |

<> | not equal to |
