Exams That Give You a Calculator: CPA, Series 7, and EA

Not every finance exam wants you to buy anything. Three of the biggest, the CPA, the FINRA Series exams, and the Enrolled Agent exam, ban personal calculators outright and hand you one inside the testing software. Knowing exactly what you get changes how you should practice.

I build exam prep for a living, and candidates for these exams often waste time shopping for a calculator they are not allowed to bring. Here is what each exam provides and how to prepare for the tool you will actually use.

CPA: an on-screen calculator plus a spreadsheet

You cannot bring any calculator to the CPA exam. Personal belongings, including your phone, go in a locker. Instead you get two tools inside the software:

  • An on-screen calculator, available during both the multiple-choice questions and the task-based simulations.
  • A spreadsheet tool in the task-based simulations that looks and behaves like Microsoft Excel, including common formulas such as SUM, AVERAGE, PV, and FV.

One quirk matters: the on-screen calculator computes left to right and ignores order of operations. Enter 2 plus 3 times 4 and it returns 20, not 14. For any calculation with mixed operations, do it in the spreadsheet, which does respect order of operations, or break it into steps. Practicing this before exam day prevents a silent arithmetic error on a scored question.

FINRA Series exams: the test center provides one

The SIE and the Series exams (including the Series 6, 7, 63, 65, 66, and 79) do not let you bring a personal calculator. What you get depends on how you test:

  • At a Prometric test center, you are provided a basic, non-programmable, non-printing calculator, along with dry-erase boards for scratch work.
  • Online, a four-function calculator is available on screen as part of the exam.

These are simple calculators by design. The Series exams are not calculation-heavy, so a four-function tool is enough, and there is nothing to buy or learn in advance beyond getting comfortable with basic on-screen entry.

Enrolled Agent (EA): an on-screen calculator

The IRS Enrolled Agent exam (the Special Enrollment Examination) provides an on-screen calculator that works like the standard Windows calculator and is available on every question. You do not bring your own.

One administrative note for 2026: as of March 1, 2026, the EA exam is administered by PSI Services rather than Prometric, with 2026 testing rolling out from July. The on-screen calculator remains a standard four-function tool, so your prep approach does not change.

What this means for your prep

Since you cannot bring your own calculator to any of these, the goal is to make the provided tool feel familiar:

  • For the CPA exam, practice with a basic on-screen calculator and a spreadsheet, and drill the left-to-right quirk until you never trust the calculator on a mixed-operation problem.
  • For the Series and EA exams, a plain four-function calculator (even the one on your computer) mirrors what you will be handed.

FreeFellow's CPA, Series, and EA question banks are free and include full step-by-step solutions, so you can practice the actual calculations the way you will perform them on exam day, without buying hardware you are not allowed to use.
