Calculator Policy

Only two calculator models are authorized for use during CFA Program exams:

  • Texas Instruments BA II Plus (including BA II Plus Professional)
  • Hewlett Packard 12C (including the HP 12C Platinum, 12C Platinum 25th anniversary edition, 12C 30th anniversary edition, and HP 12C Prestige)

Both authorized models are widely available through retail stores or online. Buy an approved calculator early so you can practice using it as you study.

Bring the approved calculator with you on exam day; calculators will not be available at the test center. You may not borrow from or share a calculator with another candidate during the timed portion of the exam.

Find a Texas Instruments calculator distributor or purchase online.

Find a Hewlett Packard calculator distributor or purchase online.

Please note that CFA Institute does not profit from the sales of these calculators. CFA Institute does not endorse, warrant, or guarantee the calculators or any other products or services provided by these distributors.

CFA Institute strictly enforces all policies with regard to calculator usage during the exams and candidates are required to abide by the policies of CFA Institute.

Your calculator will be inspected prior to the start of the exam. Your calculator must remain on your desk in full view and proctors will continue to inspect calculators throughout the administration of the exam. Possession or use of an unauthorized calculator at the test center will result in the voiding of your exam results and may lead to the suspension or termination of your candidacy in the CFA Program. Failure by the proctors to detect an unauthorized calculator prior to the start of the exam, or your use of an unauthorized calculator at any time during the exam, does not imply that the calculator is an approved model or that your results will ultimately be reported.

Calculator covers, keystroke cards, and loose batteries are permitted in the testing room; instruction manuals are not. You may keep a small screwdriver with you if necessary to replace batteries in the BA II Plus.
