1. What is Percentage Increase?

Percentage increase measures how much a value has grown relative to its original amount, expressed as a percentage. It's commonly used to analyze price changes, growth rates, and performance improvements.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• New Price — The current or increased price
• Old Price — The original price before increase

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

3. Importance of Percentage Increase Calculation

Details: Percentage increase helps in financial analysis, price comparisons, investment returns evaluation, and tracking growth metrics in business and economics.

4. Using the Calculator

Tips: Enter both new and old prices in the same currency. The old price must be greater than zero for valid calculation.

5. Frequently Asked Questions (FAQ)

A: Absolute increase shows the actual difference (New - Old), while percentage increase shows the relative change compared to the original value.

Q2: Can percentage increase be negative?
A: Yes, if new price is lower than old price, the result will be negative, indicating a percentage decrease.

Q3: How is this different from percentage points?
A: Percentage points measure absolute difference between percentages, while percentage increase measures relative change from original value.

Q4: What if the old price was zero?
A: Calculation is undefined (division by zero). The calculator requires old price > 0.

Q5: How to interpret a 100% increase?
A: A 100% increase means the value has doubled (become twice the original amount).
