About Percentage Calculator
The Percentage Calculator is one of the tools students, shoppers and office workers reach for most on ToolsOfIndia, and it works equally well on a phone or a desktop. It is deliberately keyboard-friendly and mobile-friendly, because most Indian users will open it on a phone mid-conversation rather than at a desk. Solve everyday percentage problems in one place - find a percentage of a number, the percentage one number is of another, the increase or decrease percentage between two values, and reverse percentage questions like what number gives this result when a percentage is applied. Indian school maths, shop discounts, exam marks and salary hikes all need percentages, and the tool covers every common form so you do not have to recall the formula. Step-by-step working is shown, which helps students learn the method, and the input accepts decimals and large numbers alike. It is the small calculator that quietly gets used every day. You will find it handy when working out a percentage of marks scored, while checking a salary hike percentage, or before finding the discount percentage on a bill. Everything is free with no usage caps, and nothing asks for your email address.
