1. What is Percentage Increase?

Percentage increase measures the relative growth from an original value to a new value, expressed as a percentage. It's commonly used in finance, economics, statistics, and everyday life to track growth and changes over time.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• \( New \) — The new or current value
• \( Old \) — The original or previous value

Explanation: The formula calculates the difference between new and old values, divides by the original value to get the relative change, then multiplies by 100 to convert to percentage.

3. Importance of Percentage Increase Calculation

Details: Percentage increase is essential for analyzing growth rates, investment returns, price changes, performance improvements, and statistical trends across various fields including business, economics, and scientific research.

4. Using the Calculator

Tips: Enter both old and new values in the same units. Values must be positive numbers. The calculator will compute the percentage increase automatically.

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, showing that the value has gone down from the original.

Q2: Can I use this for percentage decrease calculations?
A: Yes, when the new value is smaller than the old value, the result will be negative, representing a percentage decrease.

Q3: What's the difference between percentage increase and percentage points?
A: Percentage increase measures relative change, while percentage points measure absolute difference between two percentages.

Q4: How do I interpret a 100% increase?
A: A 100% increase means the value has doubled - the new value is exactly twice the original value.

Q5: Can I calculate percentage increase between percentages?
A: Yes, but be careful - increasing from 10% to 20% is a 100% increase in the percentage value, not a 10 percentage point increase.
