Percentage Calculator is an online tool available for free that helps you to calculate percentages
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.
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.
So, in this case, 37.5% of the marbles in the jar are blue.
To calculate the percentage difference between two values, follow these steps:
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.
To calculate the percentage increase between two values, follow these steps:
Percentage Increase = ((New Value - Original Value) / Original Value) * 100
To calculate the percentage decrease between two values, follow these steps:
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.
