Easy Percentage Calculator

Percentage Calculator is a simple, free-to-use, offline app for the percentage math you actually need. No sign-up, no waiting for a page to load. Just open the app and calculate. Four calculators, one screen: 1. What is X% of Y? Find a percentage of any number. Example: "What is 15% of 200?" → 30. 2. X is what percent of Y? Find out what percentage one number is of another. Example: "50 is what percent of 200?" → 25%. 3. Percentage Increase or Decrease See how much a value has gone up or down, as a percentage. Example: going from 80 to 100 is a 25% increase. 4. Find the Original Amount If you have a total that already includes a percentage and you need to work backwards to find the original number before that percentage was added. This calculator does it in one step. Just enter the total and the percentage, and get both the original amount and the amount that percentage added. Example: a total of 3,000 that already includes a 5% addition works out to an original amount of 2,857.14, with 142.86 being the added amount.
