1. What is Percentage Increase?

Percentage increase measures how much a quantity grows relative to its original value, expressed as a percentage. It's commonly used in finance, statistics, and everyday calculations to understand growth rates.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• \( Original\ Value \) — The starting value before increase
• \( Percentage \) — The percentage increase to apply

Example: Increasing 9 by 100% results in 18 (9 × (1 + 100/100) = 9 × 2 = 18).

3. Importance of Percentage Calculations

Details: Percentage increases are fundamental in financial calculations (interest rates, price changes), performance metrics (sales growth), and scientific measurements (concentration changes).

4. Using the Calculator

Tips: Enter the original value and the percentage increase you want to apply. Both values must be non-negative numbers.

5. Frequently Asked Questions (FAQ)

Q1: What does a 100% increase mean?
A: A 100% increase doubles the original value (multiplies it by 2).

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

Q3: Can I calculate percentage decreases?
A: Yes, by entering a negative percentage (though this calculator requires positive values - you could modify it to handle decreases).

Q4: What's the difference between percentage increase and compound growth?
A: Percentage increase is a one-time calculation, while compound growth applies percentage changes repeatedly over periods.

Q5: How do I reverse a percentage increase?
A: To find the original value after an increase, divide the new value by (1 + percentage/100).
