Three quick percentage calculators: find a percentage of a number, work out what percentage one number is of another, and calculate percentage change.
Percentages come up everywhere: discounts, exam marks, tax, salary increases and price changes. This calculator answers the three common questions: what is X% of a number, what percentage one number is of another, and the percentage change between two values.
Pick the question, type the numbers and the answer appears as you type. A price rising from 200 to 250, for example, is a 25% increase. For shopping discounts and sales tax, the discount and VAT calculators give more detail.
It is free, works on any device and runs entirely in your browser.
Percentage change is (new value − old value) ÷ old value × 100, showing a negative result for a decrease.
