Best Calculator to Use for Exam P

Your definitive 2026 guide and interactive tool for choosing the perfect SOA-approved calculator for the Probability Exam.

Exam P Calculator Recommendation Tool

Answer the questions below to find the best calculator to use for Exam P based on your needs.

What is the ‘Best Calculator for Exam P’?

When searching for the “best calculator to use for exam p,” you’re not looking for a web-based tool to solve probability problems. You’re looking for a specific, physical, hand-held calculator model that is approved for use during the official Society of Actuaries (SOA) Exam P. The SOA has very strict rules about which devices are allowed in the testing room. Using a non-approved calculator will result in immediate disqualification.

This page provides an interactive recommendation tool to help you select the best calculator for your needs from the official SOA-approved list. It also offers a deep dive into the most popular choices, helping future actuaries make an informed decision. The most common point of confusion is thinking any scientific calculator will do, but only a select list of Texas Instruments models are permitted.

The Official SOA-Approved Calculator List for Exam P

The Society of Actuaries explicitly lists the calculator models that are permitted for their exams. Using any other model is a violation of the rules. As of early 2026, the approved list primarily includes specific models from Texas Instruments.

List of SOA-Approved Calculators (2026)

Model Name	Key Feature	Power Source
TI-30XS MultiView	4-line “textbook” display	Solar (with battery backup)
TI-30XB MultiView	4-line “textbook” display	Battery only
TI-30X II (IIS or IIB)	2-line display	Solar or Battery
TI-30Xa	1-line display	Battery
BA II Plus / Professional	Financial functions	Battery
BA-35	Basic financial functions	Solar

Note: While the BA II Plus is approved, it is a financial calculator and is the primary choice for Exam FM, not Exam P. The best calculator to use for Exam P is almost universally considered to be a scientific one, like the TI-30XS MultiView. You can find more about SOA exam rules on our dedicated page.

Practical Examples: Which Calculator to Choose?

Example 1: The Standard Student

• Input Preference: Wants the most intuitive display to reduce errors.
• Unit: Primary calculator.
• Result: The TI-30XS MultiView is the clear winner. Its 4-line “MathPrint” display shows fractions, integrals, and formulas exactly as they appear in textbooks, which is a huge advantage under exam pressure.

Example 2: The Cautious Candidate

• Input Preference: Worries about solar-powered calculators failing in a poorly lit exam room.
• Unit: Primary calculator.
• Result: The TI-30XB MultiView is the best choice. It has the exact same functionality as the popular XS model but is purely battery-powered, offering peace of mind.

1. Select Your Key Feature: Choose what matters most to you. The “Multi-Line Display” is the most popular choice for Exam P candidates.
2. Choose its Role: Indicate if this will be your main calculator or a backup. It’s highly recommended to bring two calculators to the exam.
3. Review the Recommendation: The tool will output the top model, its key features, and a brief explanation.
4. Read the Detailed Review: The article below provides more context on the top choices and their specific functions, such as using the TI-30XS for probability distributions.

Key Factors That Affect Your Choice

• SOA Approval: This is non-negotiable. The calculator MUST be on the official list.
• Display Type: A MultiView (4-line) display is vastly superior to a 2-line or 1-line display for complex probability formulas. You can see your input and avoid mistakes.
• Power Source: The TI-30XS is solar-powered with a battery backup, while the TI-30XB is battery-only. Both are reliable, but some people prefer the security of a battery-only model.
• Ease of Use: The MultiView models allow for “textbook” entry, which is more intuitive than older models that rely heavily on parentheses.
• Table Function: The TI-30XS/XB has a table function that is invaluable for visualizing probability distribution functions (PDFs) and cumulative distribution functions (CDFs).
• Cost: All approved scientific calculators are affordable (typically $15-$25). The price difference between them is minimal, so features should be the deciding factor. Explore our actuarial exam prep cost analysis for more details.

Frequently Asked Questions (FAQ)

What is the absolute best calculator to use for Exam P?

The overwhelming consensus is the Texas Instruments TI-30XS MultiView. Its combination of a multi-line display, intuitive input, and powerful table function makes it the top choice for probability calculations.

Can I bring two calculators into the exam?

Yes, the SOA allows you to bring more than one approved calculator into the exam room. It is a highly recommended strategy in case one fails. Your second calculator could be another TI-30XS or a simpler model like the TI-30X II.

What is the difference between the TI-30XS and TI-30XB?

The only significant difference is the power source. The ‘S’ in TI-30XS stands for Solar (it has a solar panel with a battery backup), and the ‘B’ in TI-30XB stands for Battery (it is powered only by a battery). Their functionality is identical.

Is a financial calculator like the BA II Plus good for Exam P?

While the BA II Plus is on the approved list, it is not recommended for Exam P. It’s a financial calculator designed for interest rate and annuity calculations, making it the top choice for Exam FM. For the probability and calculus on Exam P, a scientific calculator like the TI-30XS is far more efficient.

Do I have to clear the calculator’s memory?

Yes, for certain models, including the TI-30X MultiView and BA II Plus, the exam proctor will require you to show that the memory has been cleared before you begin the exam.

Why can’t I use my advanced graphing calculator like a TI-84?

Calculators with graphing capabilities, text storage, or communication features (like the TI-84, TI-89, or Nspire) are banned by the SOA to ensure a fair and standardized testing environment.

How do I use the TI-30XS for probability functions?

The TI-30XS has a ‘prb’ button for combinations (nCr) and permutations (nPr). More importantly, its ‘table’ function allows you to input a function (like a binomial PDF) and see a list of probabilities for different values of ‘x’, which is a massive time-saver. Check our guide on the best Exam P study guide for tips.

Where can I buy the best calculator for Exam P?

The TI-30XS and other approved models are widely available at major office supply stores, electronics retailers, and online platforms like Amazon. Check out our actuarial resources page for links.
