1. What is Price Increase Percentage?

The price increase percentage measures how much a price has risen compared 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, divides by the old price to get the relative change, then multiplies by 100 to convert to percentage.

3. Importance of Price Increase Calculation

Details: Calculating price increases helps businesses adjust pricing strategies, allows consumers to understand inflation, and helps investors evaluate cost changes over time.

4. Using the Calculator

Tips: Enter both old and new prices in the same currency. Prices must be positive numbers. The calculator will show the percentage increase between the two values.

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 difference?
A: Percentage increase specifically measures growth from an original value, while percentage difference compares two values without reference to which is original.

Q3: Can I use this for salary increases?
A: Yes, the same formula works for calculating salary increases, where old price is original salary and new price is increased salary.

Q4: What if the old price was zero?
A: The calculation is undefined when old price is zero, as you cannot divide by zero. The calculator requires positive values.

Q5: How do I calculate the original price from the increase percentage?
A: Original Price = New Price / (1 + (Percentage Increase/100))
