1. What is Percentage Price Increase?

The percentage price increase measures how much a price has risen compared to its original value, expressed as a percentage. It's a fundamental calculation 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 a ratio, then converts to percentage by multiplying by 100.

3. Importance of Price Increase Calculation

Details: Calculating percentage increases helps businesses analyze pricing strategies, consumers understand inflation impacts, and investors evaluate cost changes in markets.

4. Using the Calculator

Tips: Enter both prices in the same currency unit. The old price must be greater than zero. The calculator automatically handles negative results (which indicate price decreases).

5. Frequently Asked Questions (FAQ)

Q1: What does a negative percentage mean?
A: A negative result indicates a price decrease rather than an increase.

Q2: How is this different from percentage points?
A: Percentage increase is relative to the original value, while percentage points measure absolute difference between percentages.

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

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

Q5: How do I calculate compound price increases?
A: For multiple consecutive increases, you would multiply the (1 + percentage increase) factors together.
