👉 PCT, or Percentage Change, is a statistical measure used to quantify the percentage increase or decrease in a variable over a specified period. It's calculated by finding the difference between the final value and the initial value, dividing that difference by the initial value, and then multiplying by 100 to express it as a percentage. This method provides a clear, standardized way to compare changes across different datasets or time frames, making it particularly useful in economics, finance, and social sciences for analyzing trends and making informed decisions. For example, if a company's sales increased from $100,000 to $150,000 over a year, the PCT would be 50%, indicating a 50% growth.
