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 track growth in financial, statistical, and scientific contexts.

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 values, divides by the original value to get relative change, then converts to percentage by multiplying by 100.

3. Practical Applications

Details: Percentage increase is used in:

• Financial analysis (stock growth, revenue increase)
• Academic grading (score improvements)
• Business metrics (sales growth)
• Scientific research (population growth rates)

4. Using the Calculator

Tips:

• Enter both values as positive numbers
• 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 simple difference (New - Old), while percentage increase shows relative change compared to original value.

Q2: Can percentage increase be more than 100%?
A: Yes, when the new value is more than double the old value (e.g., from 10 to 30 is 200% increase).

Q3: How to interpret negative percentage increase?
A: A negative result means percentage decrease (new value is smaller than old value).

Q4: Why can't old value be zero?
A: Division by zero is mathematically undefined. Use absolute difference instead when starting from zero.

Q5: How is this different from percentage points?
A: Percentage points measure absolute difference between percentages, while percentage increase measures relative change from original value.
