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 finance, economics, science, and everyday life.

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 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 fundamental for analyzing growth trends, comparing changes over time, setting performance targets, and making data-driven decisions in business and research.

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). The calculator accepts decimal values for precise calculations.

5. Frequently Asked Questions (FAQ)

Q1: What if the percentage is negative?
A: A negative result indicates a percentage decrease rather than increase, showing the value has gone down.

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

Q3: What's the maximum percentage increase possible?
A: There's no theoretical maximum. A value increasing from 1 to 2 is a 100% increase, from 1 to 3 is 200%, etc.

Q4: How to interpret a 100% increase?
A: A 100% increase means the value has doubled. The new value is twice the old value.

Q5: Can I calculate percentage decrease with this formula?
A: Yes, the result will be negative for decreases. Alternatively, you can reverse the values (put smaller value as new value).
