Auditor Costs

  • Auditors under the age of 55 pay a flat rate of $250.00 per term.
  • Auditors aged 55 and older pay a flat rate of $80 per term (for CU Boulder alumni), and a flat rate of $95 per term (for non-alumni). If you are also retired CU faculty, please contact to let us know after you submit your application.

Typically, there are no additional course fees except for when an instructor requires “Day 1 Digital Access” to online course materials. The fee for access to these online course materials is charged by the University Bookstore to all students in the class including auditors. For information about this fee and how to opt-out, visit the University Bookstore’s Day 1 Digital Access website.

Bills become available in Buff Portal (CUBill&Pay for authorized payers) by the second Thursday of each month after you are enrolled in a class. Payment is due on the 5th of the following month. Postmarks and post-dated checks are not honored. Dates may be subject to change without notice.

You can pay for your course after you receive your enrollment confirmation email. There are two ways to make a payment:

  • Pay online*. You can access online payments via Buff Portal via the Tuition & Fees card. Click on Balance Summary, then View/Pay Bill, which will direct you to CU Bill&Pay, the university’s secure online billing and payment system.
  • Pay in person at the Continuing Education building (1505 University Avenue) with credit card*, check or cash.

*You will be assessed a nonrefundable 2.85% service fee for credit card payments.

There is no automatic refund for dropped classes. Additionally, auditors are not eligible for financial aid, scholarships, or payment plans.

Contact the CE Accounting team at 303-492-2212 if you have any questions regarding auditor fees and payments.
