Inputs and Outputs

• initialValue: The starting point of the measurement. (Measured in appropriate units, e.g., USD, meters)
• finalValue: The endpoint of the measurement. (Measured in appropriate units, e.g., USD, meters)
• Output: The percentage increase, displayed as a percentage.

Real-Life Examples of Percentage Increase

Let's relate this concept to some everyday scenarios and see how it applies in different contexts.

Common Mistakes to Avoid

While calculating percentage increases is straightforward, there are common pitfalls to watch out for:

• Using incorrect units: Ensure both the initial and final values are measured in the same units.
• Misinterpreting the result: Remember, a negative percentage increase indicates a decrease, not an increase.
• Incorrect initial value: Never use zero or a negative number as the initial value, as this makes the percentage increase calculation invalid.

FAQs: Calculating Percentage Increase

Let's address some frequently asked questions to clear up any lingering confusion.
