1. What is Price Increase Percentage?

The Price Increase Percentage measures how much a price has grown relative to its original value. It's a key metric in economics, finance, and business to understand inflation, cost changes, and pricing strategies.

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 as a proportion of the original price, then converts it to a percentage.

3. Importance of Price Increase Calculation

Details: Calculating price increases helps businesses adjust pricing strategies, allows consumers to track inflation, and helps economists analyze market trends. It's essential for budgeting, financial planning, and cost analysis.

4. Using the Calculator

Tips: Enter both prices in the same currency. The old price must be greater than zero. The calculator will show the percentage increase (positive) or decrease (negative).

A: Absolute increase is the simple difference (New - Old), while percentage increase shows this difference relative to the original price.

Q2: Can the result be negative?
A: Yes, if the new price is lower than the 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 an original value.

Q4: What if the old price was zero?
A: The calculation is undefined (division by zero). The calculator requires positive old price values.

Q5: How can I calculate compound annual growth rate (CAGR)?
A: For multi-year growth, use CAGR formula: [(Ending Value/Beginning Value)^(1/Number of Years)] - 1.
