Impact Tracking

Cost savings is often an important part of calculating the impact of your resource. Cost savings, or cost avoidance, is the amount of money students will avoid spending by using your OER instead of a commercial textbook. 

To calculate cost savings, you will need to know: 

  • The number of sections using the resource
  • The number of students enrolled in those sections. Alternately, the number of students enrolled can replace these first two numbers.
  • The cost of the textbook that the OER originally replaced. Most often, the cost of purchasing a new book from the bookstore, or the list price on Amazon, is used. Some in the OER community use $100 as a standard amount for savings to account for the fact that even though a book might cost more than that, not all students would have purchased the title.

Cost Savings for 1 semester = (number of sections) x (average number of students per section) x (cost of book being replaced).

You can add up each semester's savings for cumulative savings over time.

In addition to tracking cost savings, you might want to explore other areas of impact tracking and assessment using the resources below:
