Enter the number of people who abandon their purchase and the number of purchases initiated into the Drop Off Rate Calculator. The calculator will evaluate the Drop Off Rate. 

Drop Off Rate Formula

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

DOR = #A / #P * 100

Variables:

  • DOR is the Drop Off Rate (%)
  • #A is the number of people who abandon their purchase 
  • #P is the number of purchases initiated 

How to Calculate Drop Off Rate?

The following steps outline how to calculate the Drop Off Rate.


  1. First, determine the number of people who abandon their purchase. 
  2. Next, determine the number of purchases initiated. 
  3. Next, gather the formula from above = DOR = #A / #P * 100.
  4. Finally, calculate the Drop Off 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.

number of people who abandon their purchase = 50

number of purchases initiated = 100

DOR = #A / #P * 100 = ?
