1. What is Percentage Price Increase?

Percentage price increase measures how much a price has grown relative to its original value, expressed as a percentage. It's a key metric in economics, finance, and business to understand price changes over time.

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 price, divides by the original price to get relative change, then converts to percentage by multiplying by 100.

3. Importance of Price Increase Calculation

Details: Calculating percentage increases helps businesses track pricing strategies, consumers understand inflation, and investors analyze market trends. It provides a standardized way to compare price changes across different products and time periods.

4. Using the Calculator

Tips: Enter both prices in the same currency. The old price must be greater than zero. Results show how much the price has increased as a percentage of the original price.

5. Frequently Asked Questions (FAQ)

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

Q2: Can I use this for price decreases?
A: Yes, the result will be negative if the new price is lower than the old price, 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 an original value.

Q4: What if my old price was zero?
A: The calculation is undefined (division by zero). Percentage change can't be calculated when starting from zero.

Q5: How should I interpret a 100% increase?
A: A 100% increase means the price has doubled. The new price is exactly twice the old price.
