In such cases, a commonly accepted solution is to consider the percentage change as 100% (as the new value has grown by 100% starting from zero). This is not an Excel problem, rather it’s a math problem. so if you try and do this, Excel will give you a division error (#DIV/0!)
If you use the formulas we have used so far, you will have the below formula: =(100-0)/0īut you can’t divide a number by zero in math. While calculating percentage change in excel is quite easy, you will likely face some challenges when there is a zero involved in the calculation.įor example, if your old value is zero and your new value is 100, what do you think is the percentage increase. Since all the formulas are linked to the cell, the formulas would automatically update. The benefit of having the percentage change value in a separate cell is that in case you have to change the calculation by changing this value, you just need to do that in one cell. Suppose I have the data set as shown below where I have the old price of an item in cell A2 and the new price in cell B2. The most common scenario where you have to calculate percentage change is when you have two values, and you need to find out how much change has happened from one value to the other.įor example, if the price of an item increases from $60 to $80, this could be a scenario where you have to calculate how much increase in percentage happened in this case.
