Use the NOT function, one of the logical functions, when you want to make sure one value is not equal to another.


Examples of the NOT function to reverse arguments.  E.G. =NOT(1+1=2)

The NOT function reverses the value of its argument.

One common use for the NOT function is to expand the usefulness of other functions that perform logical tests. For example, the IF function performs a logical test and then returns one value if the test evaluates to TRUE and another value if the test evaluates to FALSE. By using the NOT function as the logical_test argument of the IF function, you can test many different conditions instead of just one.



The NOT function syntax has the following arguments:

  • Logical    Required. A value or expression that can be evaluated to TRUE or FALSE.


If logical is FALSE, NOT returns TRUE; if logical is TRUE, NOT returns FALSE.


Here are some general examples of using NOT by itself, and in conjunction with IF, AND and OR.

Examples of NOT with IF, AND and OR functions




A2 is NOT greater than 100

=IF(AND(NOT(A2>1),NOT(A2<100)),A2,"The value is out of range")

50 is greater than 1 (TRUE), AND 50 is less than 100 (TRUE), so NOT reverses both arguments to FALSE. AND requires both arguments to be TRUE, so it returns the result if FALSE.

=IF(OR(NOT(A3<0),NOT(A3>50)),A3,"The value is out of range")

100 is not less than 0 (FALSE), and 100 is greater than 50 (TRUE), so NOT reverses the arguments to TRUE/FALSE. OR only requires one argument to be TRUE, so it returns the result if TRUE.

Sales Commission Calculation

Here is a fairly common scenario where we need to calculate if sales people qualify for a bonus using NOT with IF and AND.

Example of calculating a sales bonus with IF, AND, and NOT.  Formula in cell E14 is =IF(AND(NOT(B14<$B$7),NOT(C14<$B$5)),B14*$B$8,0)
  • =IF(AND(NOT(B14<$B$7),NOT(C14<$B$5)),B14*$B$8,0)- IF Total Sales is NOT less than Sales Goal, AND Accounts are NOT less than the Account Goal, then multiply Total Sales by the Commission %, otherwise return 0.
