How this calculator works

Core formula

percent of, percent share, or percentage change depending on mode

The calculator switches between three common percentage formulas: finding a share of a number, finding what percent one value is of another, and measuring change from one value to another.

  • Percentage change uses the first value as the base.
  • Formatted output adds percent signs only when the mode requires it.
