Enter the total decrease and the total time into the Calculator. The calculator will evaluate the Decrease Over Time. 

Decrease Over Time Formula

DOT = D / T


  • DOT is the Decrease Over Time (decrease/time)
  • D is the total decrease
  • T is the total time

To calculate the Decrease Over Time, divide the total decrease by the time.

How to Calculate Decrease Over Time?

The following steps outline how to calculate the Decrease Over Time.

  1. First, determine the total decrease. 
  2. Next, determine the total time. 
  3. Next, gather the formula from above = DOT = D / T.
  4. Finally, calculate the Decrease Over Time.
  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 = 157

total time = 83
