![]() The comparison here is between values of the same quantity at different times.Īs such, the frame of reference, in this case, is the original value of the quantity, and not the average of the two values (as was in the case of ‘ percentage difference’). The percentage change is a measure of how much a given quantity has changed over a period of time.įor example, you can find the percentage of change in the value of gasoline over a year, or how much production of an item has increased or decreased in a year. This will display those results where the diesel fuel values are less than gasoline as a negative number. Your formula would then be: =(B2-C2)/AVERAGE(B2,C2). If you prefer to know which instances of the diesel fuel values are greater than gasoline, you can skip the ABS function in the above formula. Note: To find the absolute value of the differences, we used the ABS function. How to Calculate the Percentage Difference in Excel Now let us look at how we can apply this to a problem in Excel. We are using the term ‘absolute difference’ because we only want the difference between the two values, irrespective of which value is larger. In other words, if the first value is value1 and the second value is value2, then the formula to calculate the percentage difference is: ( value1 - value2) / ( ( value1 + value2 ) /2 ) * 100 ![]() To calculate the percentage difference between two quantities, we need to find the absolute difference between the two numbers, divide this difference by the average of the two numbers and then multiply this value by 100. You can also use it to compare the difference in weight or size of two different items of the same type.įor instance, if you want to know how much heavier one bag of sugar is compared to another. ![]() Usually when percentage difference is calculated the direction of difference and relationship between the quantities does not matter, or is unavailable.įor example, you can use percentage difference to compare the prices of oil from two different locations. The percentage difference is a measure of how much two quantities of the same type differ from one another.
