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 analyze growth rates 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 new and old values, divides by the old value to get relative change, then converts to percentage by multiplying by 100.

3. Importance of Percentage Increase Calculation

Details: Percentage increase is crucial for understanding growth rates in business (revenue, profits), investments (returns), scientific measurements, and many other fields where relative change matters more than absolute numbers.

4. Using the Calculator

Tips: Enter both new and old values as numbers. The old value cannot be zero (as division by zero is undefined). Negative values are acceptable and will show percentage decreases when appropriate.

5. Frequently Asked Questions (FAQ)

Q1: What does a negative percentage increase mean?
A: A negative result indicates a percentage decrease rather than an increase.

Q2: How is this different from percentage difference?
A: Percentage increase compares new to old value, while percentage difference compares any two values without directionality.

Q3: What if my old value was zero?
A: The calculation is undefined because you cannot divide by zero. In such cases, consider absolute change instead.

Q4: Can I use this for percentage decrease calculations?
A: Yes, the same formula works - it will automatically show negative values for decreases.

Q5: How precise are the results?
A: Results are rounded to 2 decimal places for readability while maintaining reasonable precision.
