About Percentage Calculator

Three modes: (1) Find X% of Y, (2) X is what % of Y, (3) % change from old to new value. Used for exam marks, salary hike, discounts, GST calculations.

Percentage calculations show up constantly in everyday financial decisions — working out a discount at checkout, calculating how much a bill increased year over year, figuring out what portion of a target you've hit, or checking exam marks against a total. The three common variations (finding X% of Y, determining what percent X is of Y, and calculating percentage change between two values) each use a different formula, and mixing them up is one of the most common arithmetic mistakes people make under time pressure. This tool separates all three modes clearly so you always know exactly which calculation you're running, with results shown instantly as you type.
