Got percentage questions? We’ve got answers! Just enter any two values in the fields and hit “Calculate” to get the result. Whether you’re figuring out discounts, tips, or changes in data, this calculator makes percentage problems a breeze.

What Is a Percentage?

A percentage expresses a part of a whole in terms of 100. For example, 50% means 50 out of 100. It’s a simple way to compare numbers or proportions. You’ll often see percentages used in situations like sales discounts, test scores, and data analysis.

Instead of saying “I got 20 out of 40 questions right,” you can use percentages and say, “I got 50% right.” Handy, right?

How to Calculate Percentages

Percentages are easy to calculate once you get the hang of it. Here’s the basic formula:

Percentage = (Part ÷ Whole) × 100

For example, if you scored 18 points out of a possible 20 in a game:

  • Divide 18 by 20 (18 ÷ 20 = 0.9)
  • Multiply by 100 to convert into a percentage (0.9 × 100 = 90%)

Result? You scored 90%!

Essential Percentage Formulas

Here are some common use cases for percentages, made simple:

1. Finding a Percentage of a Value

Want to know what % of a number another number represents? Use this formula:

  • Percentage = (Part ÷ Whole) × 100

Example:

  • What percentage is 25 out of 50?
    • 25 ÷ 50 = 0.5
    • 0.5 × 100 = 50%

This tells you that 50% of the group (e.g., a class) meets the criteria.

2. Percentage Change: Increase or Decrease

Use the percentage change formula to measure growth or decline:

  • Percentage Change = [(New Value – Original Value) ÷ Original Value] × 100

Examples:

  • Finding an increase:
    Want to calculate a 10% increase on $500?
    • Multiply 500 by 1.10 (500 × 1.10 = 550).
      The result is $550 (a $50 increase).
  • Finding a decrease:
    Want to calculate a 10% decrease on $500?
    • Multiply 500 by 0.90 (500 × 0.90 = 450).
      The result is $450 (a $50 decrease).

3. Percentage Difference

To compare two values, use this formula:

  • Percentage Difference = [(|Value 1 – Value 2| ÷ Average of the Two Values) × 100]

Example:

  • Compare 6 and 10:
    • Difference = |10 – 6| = 4
    • Average = (10 + 6) ÷ 2 = 8
    • Percentage Difference = (4 ÷ 8) × 100 = 50%

This means there’s a 50% difference between the two numbers.
