How to Calculate Exchange Ratio?

The following example problems outline how to calculate Exchange Ratio.

Example Problem #1:

  1. First, determine the equity purchase price ($).
    • The equity purchase price ($) is given as: 56.
  2. Next, determine the current share price ($).
    • The current share price ($) is provided as: 70.
  3. Finally, calculate the Exchange Ratio using the equation above: 


The values given above are inserted into the equation below and the solution is calculated:

EXR = 56 / 70 = .80

Example Problem #2: 

For this problem, the variables required are provided below:

equity purchase price ($) = 70

current share price ($) = 90

Test your knowledge using the equation and check your answer with the calculator above.
