Enter the total decrease and the overall value into the Calculator. The calculator will evaluate the Decrease Rate.

## Decrease Rate Formula

DR = TD / OV * 100

Variables:

- DR is the Decrease Rate (%)
- TD is the total decrease
- OV is the overall value

To calculate Decrease Rate, divide the total decrease by the overall value, then multiply by 100.

## How to Calculate Decrease Rate?

The following steps outline how to calculate the Decrease Rate.

- First, determine the total decrease.
- Next, determine the overall value.
- Next, gather the formula from above = DR = TD / OV * 100.
- Finally, calculate the Decrease Rate.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

total decrease = 80

overall value = 1000
