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

To calculate the reduction rate, divide the difference in values by the initial value, then multiply by 100.

## How to Calculate Reduction Rate?

The following example problems outline how to calculate Reduction Rate.

Example Problem #1:

1. First, determine the current value.
• The current value is given as: 30.
2. Next, determine the initial value.
• The initial value is provided as: 50.
3. 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
