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 to track growth, inflation, performance improvements, and other comparative metrics.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• \( \text{Number1} \) — Original value
• \( \text{Number2} \) — New value

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

3. Importance of Percentage Increase Calculation

Details: Percentage increase is fundamental in business (sales growth), finance (investment returns), economics (inflation rates), and science (experimental results). It provides a standardized way to compare changes across different scales.

4. Using the Calculator

Tips: Enter both numbers (original and new values). The calculator will show the percentage increase. Note that the original value cannot be zero (division by zero is undefined).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between percentage increase and absolute increase?
A: Absolute increase is simply the difference (Number2 - Number1), while percentage increase shows that difference relative to the original value.

Q2: How do I interpret a negative percentage increase?
A: A negative result indicates a percentage decrease rather than an increase.

Q3: What if my original value is zero?
A: Percentage change from zero is undefined mathematically, as it would require division by zero.

Q4: How is this different from percentage points?
A: Percentage points measure absolute difference between percentages, while percentage increase measures relative change from an original value.

Q5: Can I calculate percentage decrease with this calculator?
A: Yes, if Number2 is less than Number1, the result will be negative, indicating a percentage decrease.
