1. What is Percentage Increase?

Percentage increase measures how much a quantity has grown relative to its original value, expressed as a percentage. It's commonly used in finance, economics, statistics, and everyday comparisons.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• New Value — The current or final value
• Old Value — The original or starting value

Explanation: The formula calculates the difference between the new and old values, divides by the old value to get the relative change, then converts to a percentage by multiplying by 100.

3. Importance of Percentage Increase Calculation

Details: Percentage increase is essential for understanding growth rates, comparing changes over time, analyzing financial performance, and making data-driven decisions in business and research.

4. Using the Calculator

Tips: Enter both old and new values as positive numbers. The old value must be greater than zero (division by zero is undefined). Results are rounded to two decimal places.

5. Frequently Asked Questions (FAQ)

Q1: What if the result is negative?
A: A negative result indicates a percentage decrease rather than increase.

Q2: How is this different from percentage difference?
A: Percentage increase measures change from an original value, while percentage difference compares two values without reference to which is original.

Q3: What's the maximum possible percentage increase?
A: There's no theoretical maximum. From an old value approaching zero, the percentage increase can approach infinity.

Q4: How do I calculate compound percentage increases?
A: For multiple periods, use the formula: Final Value = Initial Value × (1 + r)^n where r is the rate and n is number of periods.

Q5: Why use percentages instead of absolute numbers?
A: Percentages provide standardized comparison across different scales and magnitudes.
