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 changes over time.

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 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. Importance of Percentage Increase Calculation

Details: Percentage increase is widely used in financial analysis (stock prices, revenue growth), scientific research (population growth, experimental results), and everyday situations (price changes, salary increases).

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). Results are rounded to 2 decimal places.

5. Frequently Asked Questions (FAQ)

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

Q2: How is this different from percentage difference?
A: Percentage increase compares to the original value only, while percentage difference compares two values symmetrically.

Q3: What's the maximum percentage increase possible?
A: There's no theoretical maximum. A value going from near-zero to a large number can result in very high percentage increases.

Q4: Why can't the old value be zero?
A: Division by zero is mathematically undefined. You cannot calculate percentage change from zero.

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