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

3. Importance of Percentage Increase Calculation

Details: Percentage increase is fundamental in analyzing growth rates, comparing changes over time, evaluating investment returns, and understanding statistical trends across various fields.

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 show the percentage increase (positive) or decrease (negative).

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 percentage increase different from absolute increase?
A: Absolute increase is the simple difference (new - old), while percentage increase shows the relative change compared to the original value.

Q3: Can I use this for percentage decrease calculations?
A: Yes, the same formula works for decreases which will show as negative percentages (or you can take the absolute value).

Q4: Why do I get an error when Old Value is zero?
A: The calculation requires division by the old value, which is mathematically undefined when zero.

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