Why Use a Percentage Calculator?
Percentages are an integral part of our daily lives—whether you're a student trying to calculate your final grade, a shopper trying to figure out the exact discount during a holiday sale, or a business owner calculating profit margins and revenue growth. Doing these calculations manually or in your head is prone to error and can lead to costly mistakes.
Most default calculators only offer a basic % button that can be confusing to use for complex scenarios like finding the percentage increase between two numbers or reverse-calculating an original price from a discounted amount.
Our comprehensive set of online percentage calculators simplifies all these tasks by breaking them down into specific tools. Simply choose your scenario (e.g., "Discount Calculator" or "Marks Calculator"), punch in the raw numbers, and let our tool handle the complex formulas instantly in your browser. No math degree required!

Frequently Asked Questions
How to calculate percentage of marks?
Divide your scored marks by the total marks, then multiply by 100. For example, if you scored 450 out of 500: (450 / 500) * 100 = 90%.
How to find discount price?
Multiply the original price by the discount percentage to get the savings. Subtract savings from the original price. Example: $100 with 20% off: $100 - ($100 * 0.20) = $80.
How do I calculate percentage increase?
Subtract the original value from the new value, divide by the original value, then multiply by 100. Formula: ((New - Old) / Old) * 100.
