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, statistics, and general data analysis to compare growth between two values.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• \( \text{Number1} \) — The original or initial value
• \( \text{Number2} \) — The new or final value

Explanation: The formula calculates the difference between the two numbers, divides by the original number to get the relative increase, then multiplies by 100 to convert to a percentage.

3. Importance of Percentage Increase Calculation

Details: Percentage increase is widely used in financial analysis (stock growth, price changes), business metrics (sales growth), scientific research (experimental results), and everyday situations (price comparisons).

4. Using the Calculator

Tips: Enter both numbers (Number1 as the original value and Number2 as the new value). Both values must be positive numbers. The calculator will show the percentage increase from Number1 to Number2.

5. Frequently Asked Questions (FAQ)

Q1: What if Number1 is zero?
A: The calculation is undefined when the original number is zero, as you cannot divide by zero. The calculator requires positive values.

Q2: What does a negative result mean?
A: A negative percentage increase indicates a decrease rather than an increase (when Number2 is less than Number1).

Q3: How is this different from percentage difference?
A: Percentage increase compares to the original value only, while percentage difference compares to the average of both values.

Q4: Can I use this for percentage decrease?
A: Yes, the same formula works - it will automatically show a negative percentage for decreases.

Q5: How precise are the results?
A: Results are rounded to 2 decimal places for readability while maintaining reasonable precision.
