Frequently Asked Questions (FAQ)
How do you calculate a percentage of a number?
To calculate a percentage of a number, you convert the percentage to a decimal and multiply it by the number. For example, to find 20% of 50, you would calculate (20 / 100) * 50, which equals 10. Our calculator does this for you automatically.
How do you calculate percentage increase or decrease?
To calculate the percentage change between two numbers, subtract the old value from the new value, divide that result by the old value, and then multiply by 100. The formula is: ((New Value - Old Value) / Old Value) * 100.
How do you calculate a discount?
To calculate a discount, convert the discount percentage to a decimal and multiply it by the original price to find the discount amount. Then, subtract the discount amount from the original price to get the final sale price.
