The Percentage Difference Calculator is here to help you in determining the difference between two figures. We’ll teach you how to compute the % difference between two numbers and how to correctly describe what the percentage difference is and how to avoid certain typical blunders. Finally, we’ll also go through the variations between different percentage calculators and how to present the data in deceptive (but technically correct) ways to establish various points.

How to calculate percentage difference?

The Percentage Difference Calculator will calculate the percent difference between two positive values that are larger than zero. You normally calculate the percentage difference when you wish to determine the % difference between two numbers.

Perform the following computations to find the percentage difference between two values, a and b:

  • To find the absolute difference between two integers, use the following formula: (a-b) a-b) a-b) a-b)
  • Calculate the average of the two figures: 2 = (a + b)
  • Calculate the difference by multiplying it by the average: ((a + b) / 2) |a – b|
  • Multiply the result by 100 to get the percentages.

We’ll need a difference first, which is two numbers that aren’t identical. Take the numbers 24 and 32 as an example; the difference between them is 8. Now we need to convert 8 to a percentage, which requires a point of reference, and you may be wondering if you should choose 24 or 32. Unfortunately, we haven’t given these numbers any context, so none of them is a good reference point. The most honest solution is to use the average, or midway, of these two values.

The percentage difference formula

We should definitely speak about the precise method we use to generate this figure before we go into more intricate discussions concerning the percentage difference. The formula for calculating the percentage difference is as follows:

percentage difference = 100 * |a – b| / ((a + b) / 2)

To be more explicit, you may use the terms “% rise” or “percentage decline.” Use the % calculator to compare two values quickly. You may also use the % error calculator to compute the relative error.

You now know how to utilize the % difference formula. However, please bear in mind that the percentage difference calculator will not function in reverse since the formula contains an absolute value. This is why you can’t put a number in the calculator’s last two fields.

Percentage difference between two numbers

Find the absolute value of their difference and average ratio and multiply it by 100 to get the percentage difference of any two figures. Subtracting two values and comparing the difference to the initial value yields percentage growth and decrease. This is done mathematically by dividing the absolute value of the difference between two values by the original value to determine how much the original value has changed.

It involves converting a percentage to a decimal equivalent, then subtracting (lower) or adding (raise) the decimal equivalent from and to 1. When this amount is multiplied by the original number, the result will increase or decrease by the specified percentage.

When is the percentage difference useful, and when is it confusing?

It should come as no surprise to you that the value of percentage difference is at its optimum when comparing two numbers, yet this is not always the case. Therefore, we should avoid talking about percentage difference when we imply the same value throughout time. Nevertheless, we assume this should be the case since, in ordinary life, we prefer to think in terms of % change and not percentage difference.

For now, let’s consider a few cases where it is beneficial to discuss percentage differences. First, let’s imagine you wish to compare the size of two organizations in terms of their personnel. In this example, firm C has 93 workers, while company B has 117. The percentage difference is a reasonable measure to examine the difference in size between these two firms. In this situation, using the percentage difference calculator, we can see that there is a difference of 22.86 percent.

It is, however, not true to assert that firm C is 22.86 percent smaller than company B or that B is 22.86 percent larger than C. In this scenario, we would be talking about % change, which is not the same as a percentage difference.

Imagine that business C combines with company A, which employs 20,000 workers. Now the new business, CA, has 20,093 employees and the percentage difference between CA and B is 197.7 percent. Let’s take it up a notch. Now a new firm, D, with 180,000 people, combines with CA to form a corporation named CAD. CAD presently has 200.093 workers. Now, the percentage gap between B and CAD climbs only to 199.8 percent, despite CAD being 895.8 percent higher than CA in terms of percentage increase

The meaning of percentage difference in real life

The % difference is a non-directional statistic that we calculate between any two integers. However, when statistical data is published in the media, it is almost never reported correctly and exactly. Therefore, even with the best of intentions, utilizing the incorrect comparison tools can be deceptive and offer a false impression about a particular situation.

The difficulty with the percentage difference emerges when it is mistaken with the percentage increase or % reduction. We’ve seen how deceptive these metrics maybe when the incorrect computation is applied to an extreme instance, such as comparing the number of employees between CAT and B. But now that you know better, we hope you can see past these disparities and comprehend what the true data implies.

Another issue with data is that it might lead the viewer to the wrong conclusions or give the wrong impression if presented in particular ways. Let’s look at another example to illustrate how changing the statistics supplied may obviously impact how we see a situation, even though the data is the same.


What is the percentage difference between 50 and 60?     

Solution for that is (60-50):50*100 = (60:50-1)*100 = 120-100 = 20

How to measure percentage difference?

First, compute the difference (increase) between the two numbers being compared. Then multiply the answer by 100 by dividing the increase by the original amount. percent increase = Increase Original Number 100
