1. What is Percentage Price Increase?

Percentage price increase measures the relative change in price from an old value to a new value, expressed as a percentage. It helps understand the magnitude of price changes in financial analysis, economics, and business.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• \( New\ Price \) — Current or updated price value
• \( Old\ Price \) — Original or previous price value

Explanation: The formula calculates the relative change by finding the difference between new and old prices, dividing by the original price, and converting to percentage.

3. Importance of Price Increase Calculation

Details: Calculating percentage price increases is essential for inflation analysis, investment returns, cost monitoring, pricing strategies, and financial planning.

4. Using the Calculator

Tips: Enter both old and new prices in the same currency units. Values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

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

Q3: Can I use this for salary increases?
A: Yes, the same formula applies to calculate salary, wage, or income increases.

Q4: What if the old price is zero?
A: The calculation is undefined when old price is zero, as division by zero is mathematically impossible.

Q5: How accurate is this calculation?
