  • What is a Percentage Calculator?

    A Percentage Calculator is a tool designed to perform calculations involving percentages, such as finding what percent one number is of another, calculating percentage increases or decreases, and more.

  • How do I calculate the percentage of a number?

    To calculate the percentage of a number, divide the part by the whole number and then multiply by 100. For example, to find what percent 50 is of 200, divide 50 by 200, and then multiply by 100.

  • How do I calculate a percentage increase or decrease?

    To calculate a percentage increase, subtract the original number from the new number, divide the result by the original number, and multiply by 100. For a decrease, use the same method but start by subtracting the new number from the original number.

  • How do I calculate the sales/discount price?

    To calculate the sales or discount price of an item, first determine the discount percentage. Then, multiply the original price by the discount percentage and subtract the result from the original price. For example, if an item costs $100 and is on sale for 20% off, multiply $100 by 20% (or 0.20) to get $20. Subtract this from the original price ($100 - $20) to find the sale price of $80.
