Percentage Calculator

Nine stacked percentage tools — basic formulas, common phrases, difference, change, increase/decrease, and reverse calculations.

How It Works

  1. Pick a calculator block. Scroll through nine independent tools — each updates live as you type.
  2. Basic percentage. Enter any two of P%, value, and result to find the third.
  3. Common phrases. Solve "what is p% of x?", "x is what % of y?", and "x is p% of what?"
  4. Compare values. Use percentage difference (symmetric) or percentage change (from → to).
  5. Reverse calculations. Increase/decrease by % or find the original value after a percent increase.
