Nested IF function example

Excel formula: Nested IF function example
Generic formula 

The IF function can be nested inside of itself to handle multiple conditions. In the example shown, a nested IF formula is used to assign a grade to a score. The formula in D5 contains 5 separate IF functions:


This article describes the Excel nested IF construction. Usually, nested IFs are used when you need to test more than one condition and return different results depending on those tests.

Testing more than one condition

If you need to test for more than one condition, then take one of several actions, depending on the result of the tests, one option is to nest multiple IF statements together in one formula. You'll often hear this referred to as "nested IFs".

The idea of nesting comes from embedding or "nesting" one IF function inside another. In the example shown, we are using nested IF functions to assign grades based on a score. The logic for assigning a grade goes like this:

Score Grade
0-63 F
64-72 D
73-84 C
85-94 B
95-100 A

To build up a nested IF formula that reflects this logic, we start by testing to see if the score is below 64. If TRUE, we return "F". If FALSE, we move into the next IF function. This time, we test to see if the score is less than 73. If TRUE, we return "D". If FALSE, we move into yet another IF function. And so on.

Eventually, the formula we have in cell D5 looks like this:


You can see that it's important in this case to move in one direction, either low to high, or high to low. This allows us to return a result whenever a test returns TRUE, because we know that the previous tests have returned FALSE.

Making nested IFs easier to read

By their nature, nested IF formulas can be hard to read. If this bothers you, you can add line breaks inside the formula to "line up" the tests and results. This video explains how to add line breaks to a nested if.


  1. The newer IFS function can handle multiple conditions in a single function.
  2. VLOOKUP can sometimes be used to replace complicated nested ifs.
