Excel Nested IF statement - examples, best practices and alternatives

The tutorial explains how to use the nested IF function in Excel to check multiple conditions. You will also learn a few other functions that could be good alternatives to using a nested formula in Excel.

How do you usually implement a decision-making logic in your Excel worksheets? In most cases, you'd use an IF formula to test your condition and return one value if the condition is met, another value if the condition is not met. To evaluate more than one condition and return different values depending on the results, you nest multiple IFs inside each other.

Though very popular, the nested IF statement is not the only way to check multiple conditions in Excel. In this tutorial, you will find a handful of alternatives that are definitely worth exploring.

Excel nested IF statement

Here's the classic Excel nested IF formula in a generic form:

IF(condition1, result1, IF(condition2, result2, IF(condition3, result3, result4)))

You can see that each subsequent IF function is embedded into the value_if_false argument of the previous function. Each IF function is enclosed in its own set of parentheses, but all the closing parentheses are at the end of the formula.

Our generic nested IF formula evaluates 3 conditions, and returns 4 different results (result 4 is returned if none of the conditions is TRUE). Translated into a human language, this nested IF statement tells Excel to do the following:

Test condition1, if TRUE - return result1, if FALSE -
test condition2, if TRUE - return result2, if FALSE -
test condition3, if TRUE - return result3, if FALSE -
return result4

As an example, let's find out commissions for a number of sellers based on the amount of sales they've made:

Commission Sales
3% $1 - $50
5% $51 - $100
7% $101 - $150
10% Over $150

In math, changing the order of addends does not change the sum. In Excel, changing the order of IF functions changes the result. Why? Because a nested IF formula returns a value corresponding to the first TRUE condition. Therefore, in your nested IF statements, it's very important to arrange the conditions in the right direction - high to low or low to high. In our case, we check the "highest" condition first, then the "second highest", and so on:

=IF(B2>=150, 10%, IF(B2>=101, 7%, IF(B2>=51, 5%, IF(B2>=1, 3%, ""))))

Excel nested IF statement

If we arranged the conditions in the reverse order, from bottom up, the results would be all wrong because our formula would stop after the first logical test for any value greater than 1. Let's say, we have $100 in sales - it is greater than 1, so the formula would not check other conditions and return 3% as the result.

As you see, it takes quite a lot of thought to build the logic of a nested IF statement correctly all the way to the end. And although Microsoft Excel allows nesting up to 64 IF functions in one formula, it is not something you'd really want to do in your worksheets. So, if you (or someone else) are staring at your Excel nested IF formula trying to figure out what it actually does, it's time to reconsider your strategy and probably choose another tool in your arsenal.

Nested IF with OR/AND conditions

In case you need to evaluate a few sets of different conditions, you can express those conditions using OR as well as AND function, nest the functions inside IF statements, and then nest the IF statements into each other.

Nested IF in Excel with OR statements

By using the OR function you can check two or more different conditions in the logical test of each IF function and return TRUE if any (at least one) of the OR arguments evaluates to TRUE. To see how it actually works, please consider the following example.

Supposing, you have two columns of sales, say January sales in column B and February sales in column C. You wish to check the numbers in both columns and calculate the commission based on a higher number. In other words, you build a formula with the following logic: if either Jan or Feb sales are greater than $150, the seller gets 10% commission, if Jan or Feb sales are greater than $100, the seller gets 7% commission, and so on.

To have it done, write a few OF statements like OR(B2>=150, C2>=150) and nest them into the logical tests of the IF functions discussed above. As the result, you get this formula:

=IF(OR(B2>=150, C2>=150), 10%, IF(OR(B2>=101, C2>=101),7%, IF(OR(B2>=51, C2>=51), 5%, IF(OR(B2>=11, C2>=1), 3%, ""))))

And have the commission assigned based on the higher sales amount:
Nested IF with multiple OR conditions

Nested IF in Excel with AND statements

If your logical tests include multiple conditions, and all of those conditions should evaluate to TRUE, express them by using the AND function.

For example, to assign the commissions based on a lower number of sales, take the above formula and replace OR with AND statements. To put it differently, you tell Excel to return 10% only if Jan and Feb sales are greater than $150, 7% if Jan and Feb sales are greater than $100, and so on.

=IF(AND(B2>=150, C2>=150), 10%, IF(AND(B2>=101, C2>=101), 7%, IF(AND(B2>=51, C2>=51), 5%, IF(AND(B2>=11, C2>=1), 3%, ""))))

As the result, our nested IF formula calculates the commission based on the lower number in columns B and C. If either column is empty, there is no commission at all because none of the AND conditions is met:
Nested IF with AND statements

If you'd like to return 0% instead of blank cells, replace an empty string (''") in the last argument with 0%:

=IF(AND(B2>=150, C2>=150), 10%, IF(AND(B2>=101, C2>=101), 7%, IF(AND(B2>=51, C2>=51), 5%, IF(AND(B2>=11, C2>=1), 3%, 0%))))

VLOOKUP instead of nested IF in Excel

When you are dealing with "scales", i.e. continuous ranges of numerical values that together cover the entire range, in most cases you can use the VLOOKUP function instead of nested IFs.

For starters, make a reference table like shown in the screenshot below. And then, build a Vlookup formula with approximate match, i.e. with the range_lookup argument set to TRUE.

Assuming the lookup value is in B2 and the reference table is F2:G5, the formula goes as follows:


Please notice that we fix the table_array with absolute references ($F$2:$G$5) for the formula to copy correctly to other cells:

VLOOKUP instead of nested IF in Excel

By setting the last argument of your Vlookup formula to TRUE, you tell Excel to search for the closest match - if an exact match is not found, return the next largest value that is smaller than the lookup value. As the result, your formula will match not only the exact values in the lookup table, but also any values that fall in between.

For example, the lookup value in B3 is $95. This number does not exist in the lookup table, and Vlookup with exact match would return an #N/A error in this case. But Vlookup with approximate match continue searching until it finds the nearest value that is less than the lookup value (which is $50 in our example) and returns a value from the second column in the same row (which is 5%).

But what if the lookup value is less than the smallest number in the lookup table or the lookup cell is empty? In this case, a Vlookup formula will return the #N/A error. If it's not what you actually want, nest VLOOKUP inside IFERROR and supply the value to output when the lookup value is not found. For example:

=IFERROR(VLOOKUP(B2, $F$2:$G$5, 2, TRUE), "Outside range")

Important note! For a Vlookup formula with approximate match to work correctly, the first column in the lookup table must be sorted in ascending order, from smallest to largest.

For more information, please see Exact match VLOOKUP vs. approximate match VLOOKUP.

IFS statement as alternative to nested IF function

In Excel 2016 and later versions, Microsoft introduced a special function to evaluate multiple conditions - the IFS function.

An IFS formula can handle up to 127 logical_test/value_if_true pairs, and the first logical test that evaluates to TRUE "wins":

IFS(logical_test1, value_if_true1, [logical_test2, value_if_true2]...)

In accordance with the above syntax, our nested IF formula can be reconstructed in this way:

=IFS(B2>=150, 10%, B2>=101, 7%, B2>=51, 5%, B2>0, 3%)

Please pay attention that the IFS function returns the #N/A error if none of the specified conditions is met. To avoid this, you can add one more logical_test/value_if_true to the end of your formula that will return 0 or empty string ("") or whatever value you want if none of the previous logical tests is TRUE:

=IFS(B2>=150, 10%, B2>=101, 7%, B2>=51, 5%, B2>0, 3%, TRUE, "")

As the result, our formula will return an empty string (blank cell) instead of the #N/A error if a corresponding cell in column B is empty or contains text or negative number.
Excel IFS statement to handle multiple conditions

Note. Like nested IF, Excel's IFS function returns a value corresponding to the first condition that evaluates to TRUE, which is why the order of logical tests in an IFS formula matters.

For more information, please see Excel IFS function instead of nested IF.

CHOOSE instead of nested IF formula in Excel

Another way to test multiple conditions within a single formula in Excel is using the CHOOSE function, which is designed to return a value from the list based on a position of that value.

Applied to our sample dataset, the formula takes the following shape:

=CHOOSE((B2>=1) + (B2>=51) + (B2>=101) + (B2>=150), 3%, 5%, 7%, 10%)

In the first argument (index_num), you evaluate all the conditions and add up the results. Given that TRUE equates to 1 and FALSE to 0, this way you calculate the position of the value to return.

For example, the value in B2 is $150. For this value all 4 conditions are TRUE, meaning index_num equals to 4, meaning the 4th value is returned, which is 10%.

Using CHOOSE instead of nested IF formula in Excel

Tip. If none of the logical tests is TRUE, index_num is equal to 0, and the formula returns the #VALUE! error. An easy fix is wrapping CHOOSE in the IFERROR function like this:
=IFERROR(CHOOSE((B2>=1) + (B2>=51) + (B2>=101) + (B2>=150), 3%, 5%, 7%, 10%), "")

For more information, please see Excel CHOOSE function with formula examples.

SWITCH function as a concise form of nested IF in Excel

In situations when you are dealing with a fixed set of predefined values, not scales, the SWIFT function can be a compact alternative to complex nested IF statements:

SWITCH(expression, value1, result1, value2, result2, …, [default])

The SWITCH function evaluates expression against a list of values and returns the result corresponding to the first found match.

In case, you'd like to calculate the commission based on the following grades, rather than sales amounts, you could use this compact version of nested IF formula in Excel:

=SWITCH(C2, "A", 10%, "B", 7%, "C", 5%, "D", 3%, "")

Or, you can make a reference table like shown in the screenshot below and use cell references instead of hardcoded values:

=SWITCH(C2, $F$2, $G$2, $F$3, $G$3, $F$4, $G$4, $F$5, $G$5, "")

Please notice that we lock all references except the first one with the $ sign to prevent them from changing when copying the formula to other cells:

SWITCH function - a compact form of a nested IF formula in Excel

Note. The SWITCH function is only available in Excel 2016 and higher.

For more information, please see SWITCH function - the compact form of nested IF statement.

Concatenating multiple IF functions in Excel

As mentioned in the previous example, the SWITCH function was introduced only in Excel 2016. To handle similar tasks in older Excel versions, you can combine two or more IF statements by using the Concatenate operator (&) or the CONCATENATE function.

For example:

=(IF(C2="a", 10%, "") & IF(C2="b", 7%, "") & IF(C2="c", 5%, "") & IF(C2="d", 3%, ""))*1


=CONCATENATE(IF(C2="a", 10%, ""), IF(C2="b", 7%, ""), IF(C2="c", 5%, "") & IF(C2="d", 3%, ""))*1

Concatenating multiple IF functions in Excel

As you may have noticed, we multiply the result by 1 in both formulas. It is done to convert a string returned by the Concatenate formula to a number. If your expected output is text, then the multiplication operation is not needed.

For more information, please see CONCATENATE function in Excel.
