What Are AP Chemistry Approved Calculators?
AP Chemistry approved calculators are specific models of scientific or graphing calculators that the College Board permits students to use during the AP Chemistry examination. The purpose of this policy is to ensure a level playing field by standardizing the computational tools available to all test-takers. While a simple four-function calculator is technically allowed, it is highly discouraged due to the complexity of calculations required in stoichiometry, kinetics, and thermodynamics. Using one of the designated ap chemistry approved calculators is essential for success.
This policy applies to anyone registered to take the AP Chemistry exam. A common misconception is that any “scientific calculator” is acceptable. However, the College Board explicitly lists which models are permitted and which are forbidden. Devices with features like internet access, QWERTY (typewriter-style) keyboards, or wireless communication are strictly banned. You must consult the official AP calculator policy to confirm your device is compliant.
AP Chemistry Calculator Policy Explained
The rules for ap chemistry approved calculators are designed to allow tools that assist with complex math without giving an unfair advantage. Calculators are permitted on both the multiple-choice and free-response sections. A key difference from some other AP exams is that you are not required to clear your calculator’s memory before or after the test. Students are also permitted to bring up to two approved calculators to the exam.
Below is a table detailing the status of different calculator features according to the policy for ap chemistry approved calculators.
| Feature/Capability | Meaning | Status on Exam | Typical Use in AP Chem |
|---|---|---|---|
| Graphing | Ability to plot functions. | Allowed | Visualizing kinetics data or titration curves. |
| Scientific Functions | log, ln, exponents (EE or x10^x), roots. | Allowed & Essential | pH, equilibrium constants, rate laws. |
| QWERTY Keyboard | A typewriter-style keyboard. | Not Allowed | Prohibited to prevent unapproved communication/notes. |
| Internet Connectivity | Wi-Fi, Bluetooth, or any wireless communication. | Not Allowed | Strictly prohibited to maintain exam security. |
| CAS (Computer Algebra System) | Ability to perform symbolic manipulation (e.g., solve x+y=z for x). | Allowed | Can simplify complex equilibrium expressions but is not essential. |
| Stylus or Pen Input | Using a stylus for input. | Not Allowed | Most devices with styluses are banned, with few exceptions where the stylus itself is not permitted during the exam. |
Practical Examples of Using an Approved Calculator
Understanding how to efficiently use your device is as important as having one. Here’s how ap chemistry approved calculators are used in practice.
Example 1: pH Calculation
A student needs to find the pH of a 0.0035 M solution of HCl. The formula is pH = -log[H⁺]. On their approved TI-84 Plus, they simply press the `(-)` key, the `LOG` key, enter `0.0035`, and press `ENTER`. The calculator instantly provides the answer: 2.46. This calculation is a core skill and nearly impossible to do quickly and accurately without a proper scientific calculator. For more practice, our pH calculator is a great resource.
Example 2: Ideal Gas Law
A problem involves the Ideal Gas Law (PV=nRT) and asks to solve for the number of moles (n). Given P=1.1 atm, V=4.0 L, R=0.08206, and T=298 K, a student must calculate n = PV/RT. On their Casio fx-9750GIII, they can enter `(1.1 * 4.0) / (0.08206 * 298)`. The calculator handles the order of operations and returns the answer, 0.180 moles. The ability to enter this entire expression reduces the chance of error, highlighting the value of having one of the recommended ap chemistry approved calculators.

This tool is designed for quick and easy verification. Follow these steps:
- Enter Your Calculator Model: Type the model number from your calculator into the input box above. For instance, “TI-84 Plus CE” or “Casio fx-991EX”.
- Check the Result: The status box will update automatically as you type.
- Approved: Your calculator is on the list of ap chemistry approved calculators and is permitted for use.
- Not Approved: Your calculator model is not on the approved list or is explicitly banned.
- Conditionally Approved: Your calculator is allowed, but with specific restrictions (e.g., a stylus cannot be used). The specific rule will be noted.
- Decision-Making: If your calculator is not approved, you must obtain an approved model for the exam. If it is approved, spend time practicing with it!

Key Factors for Choosing Your Calculator
Selecting from the long list of ap chemistry approved calculators can be daunting. Consider these factors:
- Familiarity: The best calculator is the one you already know how to use. Do not switch to a completely new model a week before the exam. Practice is key.
- Class Requirements: Your teacher will likely recommend or even require a specific model. This is often the safest and best choice.
- Budget: The price of ap chemistry approved calculators varies widely, from around $20 for a solid scientific model to over $150 for a top-tier color graphing calculator.
- Other Courses: If you are also taking AP Calculus or AP Physics, investing in a good graphing calculator is a smart long-term decision. This guide to calculus calculators can provide more insight.
- Ease of Use: Some calculators, like the TI-84 series, are known for having more intuitive menu systems, which can be beneficial under time pressure.
- CAS vs. Non-CAS: A Computer Algebra System (CAS) can perform symbolic algebra. While CAS calculators are allowed, they are not necessary for AP Chemistry and can have a steeper learning curve.
Frequently Asked Questions (FAQ)
- 1. Do I absolutely need a graphing calculator for AP Chemistry?
- While not strictly mandatory (a scientific calculator is permitted), a graphing calculator is highly recommended. The list of ap chemistry approved calculators includes many powerful graphing models that significantly simplify multi-step calculations.
- 2. Is the TI-Nspire CX II CAS allowed on the AP Chemistry exam?
- Yes, as of the current policy, both the TI-Nspire CX II and the TI-Nspire CX II CAS are on the list of ap chemistry approved calculators.
- 3. What happens if I bring a non-approved calculator to the exam?
- The exam proctor will confiscate the device for the duration of the test. You would have to take the exam without a calculator, which would be a severe disadvantage.
- 4. Is it true I don’t have to clear my calculator’s memory?
- Yes, for the AP Chemistry exam specifically, you are not required to clear your calculator’s memory before or after the test.
- 5. Can I share a calculator with a friend during the test?
- No. Sharing of calculators is strictly prohibited during the exam. You may bring a backup, however.
- 6. Where is the single source of truth for the list of ap chemistry approved calculators?
- The official, most up-to-date list is always maintained on the College Board’s website under their calculator policies page.
- 7. Is a four-function calculator sufficient?
- No. While technically permitted, it is completely inadequate for the logarithmic and exponential calculations required. It is not a realistic choice among the ap chemistry approved calculators.
- 8. Can I use a calculator app on my phone or tablet?
- No. All phones, tablets, smartwatches, and any device with unapproved communication capabilities must be put away. You can only use a physical, handheld calculator.
