About these percentages & pricing tools
Percentages are everywhere: price rises, sale tags, VAT, pay rises and pack sizes. These calculators cover the questions people actually ask, from how much something changed to what the price was before a discount.
Work out a percentage increase or decrease, go backwards from a final price to the original, stack several discounts and a coupon, or compare packs of different sizes to find the cheapest per unit. Each result shows the formula and the steps.
Frequently Asked Questions (FAQs)
Use the Reverse Percentage Calculator. Enter the price you paid and the discount or markup percentage, and it works back to the original price.
Percentage change compares two values relative to the first one, for example 40 to 50 is +25%. Percentage points are the plain difference between two percentages, such as 10% to 12% being 2 points.
Each discount applies to the price left after the previous one, so 20% then 10% is not 30% off. The Discount Calculator applies them in order and shows every step.
