What is a Percentage Calculator and How Does it Work?

Our percentage calculator eliminates the need for complex formulas and mental math. It’s designed to handle a wide range of percentage calculations, making your life easier:

  • Find a percentage of a number: Enter a base value and the desired percentage, and the calculator will instantly display the corresponding result. (e.g., Find 15% of $50)
  • Calculate a percentage increase or decrease: Specify a starting value, and the percentage change (positive for increase, negative for decrease), and the calculator will show the new value. (e.g., Calculate a 10% increase on $200)
  • Find the whole given a part and percentage: Enter a portion of a whole and the corresponding percentage it represents, and the calculator will determine the original whole amount. (e.g., If 25 is 20% of something, what’s the whole?)
