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 track 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 value
• Old Price — The original or baseline value

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

3. Importance of Percentage Increase Calculation

Details: Calculating percentage increase helps in financial analysis, price comparisons, investment decisions, 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. The calculator handles both positive and negative increases (which indicate decreases).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between percentage increase and absolute increase?
A: Absolute increase is the simple difference (New - Old), while percentage increase shows the change relative to the original value.

Q2: Can percentage increase be negative?
A: Yes, a negative result indicates a percentage decrease rather than an increase.

Q3: How do I interpret a 100% increase?
A: A 100% increase means the value has doubled (become twice as large as the original).

Q4: Why use percentage instead of absolute numbers?
A: Percentages allow comparison between changes of different magnitudes by standardizing to a common scale (per 100 units).

Q5: What if my old price was zero?
A: The calculation is undefined when old price is zero, as you cannot divide by zero. This calculator requires a positive old price.
