About Percent Calc

Percent Calc handles the three percentage calculations you reach for most often: finding X percent of Y, determining what percent X is of Y, and calculating how much X changes when increased or decreased by Y percent. Each calculation takes three taps.

The free version covers these core modes with no ads. A subscription adds a history of your recent calculations, copy-as-formula for pasting results into spreadsheets, and five additional modes including compound percentage, percentage difference, and original price before discount. The app works offline and requires no account.

• Calculate X percent of Y in three taps
