Methods to Calculate the Difference

There are a few different ways to approach this calculation, each with its own nuances. It's important to choose the method that best suits your specific needs. Here's an overview:

  • Simple Subtraction: This method yields the absolute difference between two numbers. The order of subtraction matters if you need to know whether the difference is positive or negative (indicating an increase or decrease, respectively). For instance, finding the difference between a starting value of 80 and an ending value of 100. 100 - 80 = 20.
  • Percentage Difference: This method expresses the difference between two numbers as a percentage of their average. It's useful when you want to compare the relative difference between two values, regardless of their direction. For a percentage difference of 5 and 7, you'd find the absolute difference (|5-7|=2), then divide by the average ((5+7)/2 = 6), resulting in approximately 33.33%.
  • Percentage Change: This method calculates the percentage increase or decrease from an initial value to a final value. It’s calculated by dividing the difference between the final and initial values by the initial value, then multiplying by 100. For a percentage change from 80 to 100, (100-80)/80 * 100 = 25%.
