What Is a Percentage Calculator?

A percentage calculator is an online tool that helps you compute percentages effortlessly. Whether you need to find out how much 20% of 500 is or determine the percentage increase from 300 to 450, this tool does the math instantly.

There are different types of percentage calculators, including:

• Basic percentage calculator – Computes a percentage of a given number.
• Percentage increase/decrease calculator – Finds the percentage difference between two values.
• Percentage change calculator – Determines how much a value has increased or decreased in percentage terms.
• Reverse percentage calculator – Helps find the original value before a percentage change.

No matter the type, these calculators simplify number crunching in seconds.

How Does a Percentage Calculator Work?

A percentage calculator uses simple mathematical formulas to deliver instant results. Here are some common calculations it can perform:

1. Finding a percentage of a number
• Formula: (Percentage × Total) ÷ 100
• Example: What is 25% of 200?
• (25 × 200) ÷ 100 = 50
2. Calculating percentage increase or decrease
• Formula: [(New Value - Old Value) ÷ Old Value] × 100
• Example: If a price rises from $50 to $65, what’s the percentage increase?
• [(65 - 50) ÷ 50] × 100 = 30%
3. Finding what percentage one number is of another
• Formula: (Part ÷ Whole) × 100
• Example: What percentage of 80 is 20?
• (20 ÷ 80) × 100 = 25%

These calculations can be done manually, but a percentage calculator does them instantly, eliminating errors and saving time.
