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 life to track growth or change.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

\[ \text{Percentage Increase} = \left( \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \right) \times 100 \]

Where:

New Value — The current or final value
Old Value — The original or initial value

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

3. Practical Applications

Details: Percentage increase is used in:

Financial analysis (stock price changes, revenue growth)
Sales performance tracking
Population growth measurements
Price inflation calculations
Academic performance improvements

4. Using the Calculator

Tips:

Enter both new and old values as positive numbers
The old value cannot be zero (division by zero is undefined)
Negative results indicate percentage decrease
Results are rounded to 2 decimal places

5. Frequently Asked Questions (FAQ)

Q1: What if my old value is zero?
A: Percentage change is undefined when the old value is zero, as it would require division by zero. The calculator will display an error message in this case.

Q2: Can I calculate percentage decrease with this?
A: Yes, if the new value is less than the old value, the result will be negative, indicating a percentage decrease.

Q3: How is this different from percentage points?
A: Percentage increase measures relative change from an original value, while percentage points measure absolute difference between two percentages.

Q4: What's the difference between percentage increase and growth factor?
A: Percentage increase shows the relative change, while growth factor is the multiplier (e.g., 20% increase = growth factor of 1.2).

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