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 or expansion.

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 starting 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 fundamental for analyzing growth rates, price changes, investment returns, performance improvements, and many other metrics across various fields.

4. Using the Calculator

Tips: Enter both old and new values as positive numbers. The old value must be greater than zero (division by zero is undefined). Results are rounded to 2 decimal places.

5. Frequently Asked Questions (FAQ)

Q1: What if the percentage increase is negative?
A: A negative result indicates a percentage decrease rather than increase, meaning the new value is smaller than the old value.

Q2: How is this different from percentage points?
A: Percentage increase is relative to the original value, while percentage points measure absolute difference between two percentages.

Q3: What's a good percentage increase?
A: This depends entirely on context. In investments, higher is better; in costs, lower increases are preferred.

Q4: Can percentage increase be over 100%?
A: Yes, this means the value has more than doubled (new value is more than twice the old value).

Q5: How do I calculate compound percentage increases?
A: For multiple periods, use the formula: Final Value = Initial Value × (1 + r)^n where r is the rate and n is periods.
