Percentage Change In Price Calculator







Tracking price changes is crucial in many areas, from shopping deals to business pricing strategies. The Percentage Change In Price Calculator helps you determine how much a price has increased or decreased in percentage terms. This is useful for understanding discounts, markups, inflation effects, or market fluctuations.

This article covers the formula, usage instructions, a practical example, and answers frequently asked questions about calculating percentage changes in prices.

Formula

The percentage change in price is calculated by subtracting the original price from the new price, dividing that difference by the original price, and then multiplying by 100 to convert it into a percentage:

Percentage Change = ((New Price − Original Price) ÷ Original Price) × 100

If the result is positive, it indicates a price increase. If negative, it indicates a price decrease.

How to Use

  1. Enter Original Price: The starting price before any change.
  2. Enter New Price: The updated or current price.
  3. Click Calculate: The calculator shows the percentage increase or decrease.

This helps you quickly assess how much a price has changed in relative terms.

Example

Suppose an item originally costs $50, and now it costs $60.

Calculation:
Change = 60 − 50 = 10
Percentage Change = (10 / 50) × 100 = 20%

This means the price increased by 20%.

If the new price was $40 instead,
Change = 40 − 50 = -10
Percentage Change = (-10 / 50) × 100 = -20%

This means the price decreased by 20%.
