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:

- First, determine the initial rate.
- The initial rate is given as: 50.

- Next, determine the final rate.
- The final rate is provided as: 90.

- 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** = ?**
