Enter the initial rate and the final rate into the Average Rate Calculator. The calculator will evaluate the Average Rate. 

Average Rate Formula

The following two example problems outline the steps and information needed to calculate the Average Rate.

AVR = (IR + FR) / 2

  • Where AVR is the Average Rate
  • IR is the initial rate 
  • FR is the final rate 

How to Calculate Average Rate?

The following example problems outline how to calculate Average Rate.

Example Problem #1:

  1. First, determine the initial rate. 
    • The initial rate is given as: 50.
  2. Next, determine the final rate. 
    • The final rate is provided as: 90.
  3. Finally, calculate the Average Rate using the equation above: 

AVR = (IR + FR) / 2

The values provided above are inserted into the equation below and computed.

AVR = (50 + 90) / 2 = 70

Example Problem #2: 

For this problem, the variables required are provided below:

initial rate = 40

final rate = 30

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

AVR = (IR + FR) / 2 = ?
