What is the calculation that represents the relative increase or decrease in value?

The calculation that represents the relative increase or decrease in value is known as Percentage Change. This method provides a way to express how much a quantity has changed in relation to its original value, allowing for a clear and standardized comparison.

To compute Percentage Change, you take the difference between the new value and the original value, divide that difference by the original value, and then multiply by 100 to convert it into a percentage. This approach effectively illustrates the magnitude of change in a format that is easily interpretable, enabling better analysis across different contexts or datasets.

For example, if a stock's price increased from $100 to $120, the calculation would be ((120 - 100) / 100) * 100, resulting in a 20% increase. This percentage format allows stakeholders to quickly grasp the scale of change without needing to reference the initial value directly.

The other options, while they may refer to changes in value, do not specifically capture the concept of relative change in a standardized way that percentage change does. Proportional Change, Ratio Change, and Value Change might detail aspects of change but do not inherently describe it as a percentage of the initial figure. Therefore, Percentage Change is the most accurate term for expressing the relative increase or
