Comprehensive Guide to Percentage Calculations
Percentages are a fundamental part of our daily lives, used in everything from shopping discounts and restaurant tips to financial reports and academic grading. Understanding how to calculate them accurately is essential for making informed decisions.
How to Calculate a Percentage of a Number
To find a percentage of a number, you simply multiply the number by the percentage expressed as a decimal. For example, to find 20% of 150, you multiply 150 by 0.20, which equals 30. Our tool automates this process, ensuring you get the right answer instantly.
Understanding Percentage Change
Percentage change is used to describe the relative change between an old value and a new value. It is calculated by taking the difference between the two values, dividing it by the original value, and then multiplying by 100. This is commonly used in finance to track stock market growth or in retail to calculate price increases and decreases.
