This piece seeks to understand how the Percentage Calculator operates, common forms of percentage computations as well as why it is a time-saving software tool for personal and professional usage.

What is a Percent?

A ‘percentage’ gives us an idea that something has been divided into segments each having one hundred parts; therefore “%” means “per hundred.” For example 25% suggests twenty-five out of every one hundred parts.

Mathematically, proportions are compared and the relative size of one amount compared with another is calculated by using percentages. For example, if a commodity has a discount of 30%, we determine that thirty percent of the original price is being discounted.

Formula for Calculating Percentages

The basic formula to calculate a percentage of a number is:

Percent = (Part / Whole) × 100

Where:

• Part represents the portion of the whole.
• Whole denotes the total value from which the part is derived.

For example, if you want to calculate 20% of $50, you would use the formula:

Percent = (20 / 100) × 50 = 10

So, $10 represents 20% of $50.

Common Percentage Calculations

This includes various percentage problems which can be solved by The Percentage Calculator from Calculator3.com like:

1. Percentage off a Number

It’s an easy calculation, just multiply two numbers: given number and percentage (in decimal form).

Example: What is 25% of 200?

Percent = (25/100) * 200 = 50

2. Percentage Increase

If you want to find out about the percentage increase between two items, you should:

Percentage Increase = (New Value − Old Value / Old Value) × 100

For instance, if the price rises from $100 to $150 what is the percentage increase?

Percentage Increase = (150 − 100) / 100 × 100 = 50%

3. Percentage Decrease

To calculate the percentage decrease between two values, use this formula:

Percentage Decrease = (Old Value − New Value / Old Value) × 100

However, if the price falls from $150 to $100 what is the percentage decrease?

Percentage Decrease = (150 − 100) / 150 × 100 = 33.33%

4. Percentage Difference

The percentage difference calculates relative difference as a percentage of their average between two values.

Percentage Difference = (Value After − Value Before) / ((Value After + Value Before) / 2) × 100

If the old value is $50 and the new value is $70, what is the percentage difference?

Percentage Difference = (70 − 50) / ((70 + 50) / 2) × 100 = 33.33%
