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 analyze growth rates, price changes, performance improvements, and other comparative metrics.

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 initial value

Explanation: The formula calculates the relative change between two values by finding the difference, dividing by the original value, and converting to a percentage.

3. Importance of Percentage Increase Calculation

Details: Percentage increase is fundamental in business (sales growth, price changes), finance (investment returns), statistics (data analysis), and everyday comparisons (inflation, salary raises).

4. Using the Calculator

Tips: Enter both old and new values as positive numbers. The old value cannot be zero (division by zero is undefined). Results show both the percentage change and absolute difference.

5. Frequently Asked Questions (FAQ)

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

Q2: How is this different from percentage points?
A: Percentage increase is relative to the original value, while percentage points measure absolute differences between percentages.

Q3: Can I calculate percentage decrease with this?
A: Yes, when new value is less than old value, the result will automatically show as negative (a decrease).

Q4: What's the difference between percentage increase and growth rate?
A: They're similar, but growth rate often refers to compound changes over time, while percentage increase compares two specific values.

Q5: How do I interpret a 100% increase?
A: A 100% increase means the value has doubled (become twice as large as the original).
