Percentage Calculator

Calculate percentages and changes.

About Percentage Calculator

The Percentage Calculator handles all the common percentage problems people search for — what is X% of Y, what percentage is X of Y, and what is the percentage increase or decrease between two numbers. Useful for shopping discounts, exam scores, salary hikes, GST calculations, tip math, and business reporting. Pick the calculation type from the dropdown, type in the numbers, and get an instant answer with the working shown. The tool also handles reverse calculations — for example, if you know a discounted price and the discount percentage, it tells you what the original price was. Many people bookmark it for quick everyday use because it is faster than opening a spreadsheet, more reliable than mental maths, and works on any device.

Common use cases for Percentage Calculator

  • Work out the final price after a 25% sale discount on a product.
  • Calculate what percentage of a class scored above a particular mark.
  • Find the percentage hike in your salary year-on-year.
  • Calculate a 10% restaurant tip without doing mental maths.
  • Work out the percentage profit you made on selling something second-hand.
  • Find the original price of a sale item if you know the discount percentage and the final price.

Tips & best practices for Percentage Calculator

  • For mental maths, remember 10% is just moving the decimal point one place — everything else builds from there.
  • Always check whether you need percentage increase versus percentage of — they're different calculations.
  • When comparing two numbers, the order matters — A is 25% more than B, but B is only 20% less than A.
  • Double-check sale 'discounts' that look too good — sometimes the original price was inflated first.
  • For business reporting, always state the base alongside the percentage to avoid confusion.
  • Use the reverse calculation to verify discount claims — if 30% off should be ₹350 saving, the original must have been ₹1,166.67.
