Final Price Formula

The following formula is used to calculate the Final Price from an initial price and a percentage change.

FP = IP(1 + C/100)
  • Where FP is the Final Price ($)
  • IP is the initial price ($) 
  • C is the percentage change (%). Use a positive value for an increase and a negative value for a decrease.

How to Calculate Final Price?

The following example problems outline how to calculate Final Price.

Example Problem #1:

  1. First, determine the initial price ($).
    1. The initial price ($) is given as: 40.
  2. Next, determine the percentage change (%).
    1. The percentage change (%) is provided as: -30 (a 30% decrease).
  3. Finally, calculate the Final Price using the equation above: 

FP = IP(1 + C/100)

The values given above are inserted into the equation below:

FP = 40(1 + (-30)/100) = 28 ($)

Example Problem #2: 

For this problem, the variables needed are provided below:

initial price ($) = 50

percentage change (%) = 70 (a 70% increase)

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.
