Work out the percentage change between two numbers, or apply a percentage increase or decrease to a starting value, all in one place. Percentage change tells you how much a value grew or shrank relative to where it started, which is essential for reading price moves, salary raises, discounts, and statistics. This calculator handles both directions: give it an old value and a new value to see the exact percent up or down, or give it a starting value and a percentage to see the resulting amount. It clearly labels whether the change is an increase or a decrease so you never confuse the sign. Enter your numbers and the answer appears at once. Everything is computed locally in your browser, so your figures stay private and there is no waiting.
