This tool designed to make working with percentages quick, clear, and reliable. See how a proposed percent increase in the cost of goods will impact the price of an item and affect your budget. Apply a tip percent to find total cost. Find out how much you’ll actually save when a product is “25% off.” Instantly find the value that represents a certain percent of a number (e.g., “What is 15% of 72?”). Also find what percent a given number is of another value (e.g., 38 is what percent of 82).
