Percentage Calculator

This calculator answers the question "what percent is X of Y?" by dividing the value by the total and multiplying by 100. For example, 45 out of 60 is 75%, and 30 out of 200 is 15%.

Percentages appear everywhere: exam scores, battery levels, market shares, survey results. Once you know the share, related tools can take you further — the percentage increase and decrease calculators measure change over time, and the discount calculator applies percentages to prices.
