The Ultimate Percentage Calculator

Percentages are everywhere in daily life—from figuring out a tip at a restaurant, to calculating sales tax, to determining the discount on a retail item. However, calculating percentages mentally can sometimes be tricky. The Percentage Calculator simplifies these everyday math problems into simple, fill-in-the-blank formulas.

Common Uses for Percentage Calculations

There are three main types of percentage problems this tool solves. First, finding 'X percent of Y' (e.g., finding a 20% tip on a $50 bill). Second, finding what percentage one number is of another (e.g., getting 45 questions right out of 60 on a test). Third, finding the percentage increase or decrease between two numbers, which is incredibly useful for tracking financial growth, stock market changes, or retail markdowns.
