Enter the initial price ($) and the final price ($) into the Change In Price Calculator. The calculator will evaluate and display the Change In Price. 

Change In Price Formula

The following formula is used to calculate the Change In Price. 

ΔP = P1 - P2
  • Where ΔP is the Change In Price ($)
  • P1 is the initial price ($) 
  • P2 is the final price ($) 

To calculate the change in price, simply subtract the final price from the initial price.

How to Calculate Change In Price?

The following example problems outline how to calculate Change In Price.

Example Problem #1:

  1. First, determine the initial price ($).
    1. The initial price ($) is given as: 600.
  2. Next, determine the final price ($).
    1. The final price ($) is provided as: 300.
  3. Finally, calculate the Change In Price using the equation above: 

ΔP = P1 – P2

The values given above are inserted into the equation below:

ΔP = 600 – 300 = 300.00 ($)

Example Problem #2: 

For this problem, the variables needed are provided below:

initial price ($) = 700

final price ($) = 80
