What is the percentage increase/decrease

A percentage calculator is a tool or mathematical formula used to determine the percentage value of a part in relation to a whole. It is a handy tool for various applications, such as calculating discounts, tax rates, proportions, and changes between two values.

To use a percentage calculator, you typically input the values for the part and the whole, and the calculator automatically computes the percentage value. It follows the formula:

Percentage = (Part / 100) * Whole

With the result obtained, you can quickly understand the proportion of the part compared to the whole, expressed as a percentage between 0 and 100. This simple and efficient tool is widely used in everyday situations, finance, science, and many other fields for quick and accurate percentage calculations.

How to calculate percentage?

Calculating a percentage involves determining the proportion of a part (the smaller value) in relation to the whole (the larger value) and expressing it as a percentage between 0 and 100. Here's a step-by-step guide using an example:

Example: You have a jar filled with 80 marbles, and you want to determine the percentage of blue marbles. Inside the jar, there are 30 blue marbles.

  1. Divide the number of blue marbles (the part) by the total number of marbles (the whole): 30 / 100 = 0.3
  2. Multiply the result by 100 to obtain the percentage value: 0.3 * 80 = 24%

So, in this case, 37.5% of the marbles in the jar are blue.

How to calculate percentage difference between two values?

To calculate the percentage difference between two values, follow these steps:

  1. Find the difference between the two values (subtract the smaller value from the larger one).
  2. Divide the absolute value of the difference by the average of the two values.
  3. Multiply the result by 100 to get the percentage difference.

The formula is:

Percentage Difference = |(Value2 - Value1) / ((Value1 + Value2) / 2)| * 100

Note: The absolute value ensures the result is always positive, regardless of which value is larger.

How to calculate the percentage increase between two values?

To calculate the percentage increase between two values, follow these steps:

  1. Find the difference between the new value and the original value (subtract the original value from the new value).
  2. Divide the difference by the original value.
  3. Multiply the result by 100 to get the percentage increase.

Percentage Increase = ((New Value - Original Value) / Original Value) * 100

How to calculate the percentage decrease between two values?

To calculate the percentage decrease between two values, follow these steps:

  1. Find the difference between the original value and the new value (subtract the new value from the original value).
  2. Divide the difference by the original value.
  3. Multiply the result by 100 to get the percentage decrease.

Percentage Decrease = ((Original Value - New Value) / Original Value) * 100

Note: If the result is positive, it represents a percentage increase. If the result is negative, it indicates a percentage decrease.
