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, inflation, salary increases, and other economic indicators.

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 the increase

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

3. Why Do Prices Increase?

Details: Prices increase due to various factors including inflation, increased production costs, higher demand, supply chain disruptions, currency devaluation, and changes in government policies or taxes.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q3: Can the result be negative?
