๏ผ… Percentage Calculator

๐Ÿ”’ ๅฎ‰ๅ…จ & ๅฎขๆˆท็ซฏๅค„็†

Three common percentage operations in one place: what is X% of Y, X is what percent of Y, and percent change from X to Y. Switch modes from the dropdown โ€” the input labels update so you don't have to remember the formula.

How to use

  1. Pick the mode that matches your question:
    • What is A% of B? โ€” e.g., "20% of 150" โ†’ 30
    • A is what percent of B? โ€” e.g., "30 is what % of 150" โ†’ 20%
    • Percent change from A to B โ€” e.g., "100 โ†’ 125" โ†’ +25%
  2. Enter the two numbers and click Calculate.

Percent change uses the formula (B โˆ’ A) / A ร— 100. A drop from 100 to 75 is โˆ’25%; rising back from 75 to 100 is +33% โ€” gains and losses are not symmetric.
