AP Calculator Policy Guide

Calculator requirements differ by AP subject. Select the exact exam and review its current calculator rules.

Last reviewed: July 2026. Policies may change.

Before test day

  1. Open the official calculator policy linked on this page.
  2. Confirm that your calculator model and features are permitted.
  3. Check whether memory clearing, mode changes or app restrictions are required.
  4. Practice with the same permitted setup you plan to use.
  5. Bring a backup plan where the test provider permits one.

On the day

Follow the instructions of the test center and proctor. An online practice calculator does not establish that a device or website is allowed during an official exam.
