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.

  1. First, determine the total decrease. 
  2. Next, determine the overall value. 
  3. Next, gather the formula from above = DR = TD / OV * 100.
  4. Finally, calculate the Decrease Rate.
  5. 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
