Enter the current value and the initial value into the Reduction Rate Calculator. The calculator will evaluate the Reduction Rate.

## Reduction Rate Formula

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

**RR = (IV -CV) / IV * 100**

- Where RR is the Reduction Rate (%)
- CV is the current value
- IV is the initial value

## How to Calculate Reduction Rate?

The following example problems outline how to calculate Reduction Rate.

Example Problem #1:

- First, determine the current value.
- The current value is given as: 30.

- Next, determine the initial value.
- The initial value is provided as: 50.

- Finally, calculate the Reduction Rate using the equation above:

RR = (IV -CV) / IV * 100

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

RR = (50 -30) / 50 * 100 = 40.00 (%)

Example Problem #2:** **

For this problem, the variables required are provided below:

current value = 40

initial value = 100

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

RR = (IV -CV) / IV * 100** = ?**
