Percentages are used every day in various circumstances, from calculating discounts at the store, determining tax rates, or even comparing statistics. It’s essential to understand how to calculate the percentage difference between two numbers accurately.

In this article, we will walk you through a step-by-step guide on how to calculate percent between two numbers with ease.

Step 1: Understand the Formula

To calculate the percentage difference between two numbers (A and B), you can use the following formula:

Percentage Difference = (|A – B| / ((A + B) / 2)) × 100

Where:

– A and B are the two numbers being compared

– |A – B| is the absolute difference between the two numbers

– (A + B) / 2 is the average of the two numbers

– Percentage Difference is the final result

Step 2: Determine Your Numerical Values

For example, let’s say you want to calculate the percentage difference between sales revenue in two different years; revenue in year one (A) was $25,000 and revenue in year two (B) was $30,000.

Step 3: Subtract One Number from Another

First, subtract one number from another:

30,000 – 25,000 = 5,000.

Step 4: Find the Absolute Difference

In this example, as there is no negative value, this step isn’t required. However, if you had a negative result from step 3, simply convert it into a positive value. This result now represents the absolute difference.

Step 5: Discover the Average of Two Numbers

To find the average of both A and B:

(A + B) / 2 = (25,000 + 30,000) / 2 = 55,000 / 2 = 27,500.

Step 6: Divide the Absolute Difference by the Average

Using the formula from step 1, divide the absolute difference by the average:

(5,000 / 27,500) = 0.1818.

Step 7: Multiply By 100 to Get Your Percentage

Lastly, multiply the result by 100:

0.1818 × 100 = 18.18%.

Conclusion

Comparing sales revenue in our example, we can now conclude that there is an 18.18% increase in revenue from year one to year two.

Understanding how to calculate the percent difference between two numbers is a valuable skill, whether you’re comparing personal finances or business data. With this comprehensive guide, you now have a step-by-step process for tackling any percentage problems that come your way.
