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 rates.

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 new and old values, divides by the old value to get relative change, then multiplies by 100 to convert to percentage.

3. Practical Applications

Details: Percentage increase is used in:

• Financial analysis (stock growth, revenue increases)
• Sales performance tracking
• Population growth studies
• 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

5. Frequently Asked Questions (FAQ)

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

Q2: How do I interpret a negative percentage increase?
A: A negative result means the value has decreased rather than increased.

Q3: What if my old value is zero?
A: Percentage increase is undefined when old value is zero, as you can't divide by zero.

Q4: Can percentage increase be more than 100%?
A: Yes, this means the new value is more than double the old value.

Q5: 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.
