where target is the named range G5. In cell E5, the result is “Yes”, because the difference in D5 is less than or equal to 5%.

Difference as percentage

To calculate the difference as a percentage, we can use a general formula like this: After converting this to cell references, we have: As the formula is copied down, it returns a percentage difference in each row. Note that some values are negative. Note: the results are decimal values like 0.05 and they must be formatted with the percentage number format to display as 5%, 7%, etc.

Compare to target

To compare the percentages to the target percentage, we use the IF function like this in cell E5: where target is the named range G5. This formula uses the ABS function to convert the percentages in column D to positive numbers. Then it uses the IF function to compare the result from ABS to the target (set to 5% in the example shown). If the logical test returns TRUE, the difference is within 5% and IF returns “Yes”. Otherwise, IF returns “No”. Notice both results are text values wrapped in double quotes (""). As the formula is copied down, we get a new result in each row. If the value in G5 is changed to a new percentage, all results recalculate.


In the example shown, column D is used to calculate the difference as a percentage, in order to make the example easier to understand. However, you can combine both formulas above into a single formula like this if needed: The result is the same, but this version does not need to use column D as a helper column.
