🧮 Series 24 Exam Calculator Rules

Understanding what tools you can—and cannot—use during the Series 24 exam is essential for a smooth testing experience. While the exam is mostly conceptual and regulation-focused, you may encounter a few math-based questions involving markups, commissions, or margin calculations. Here’s what you need to know about calculator use on test day.

🖥️ Is a Calculator Allowed?

Yes—but only the one provided on screen.

• You cannot bring your own calculator, phone, smartwatch, or any other device.
• The exam uses a basic four-function calculator embedded in the computer testing interface.
• This calculator includes functions for addition, subtraction, multiplication, and division only.

🔒 Prohibited Devices

The following items are strictly forbidden in the exam room:

• Personal calculators (scientific or basic)
• Phones and smart devices
• Notes or formula sheets
• Programmable electronics or external memory tools

Attempting to use these items may result in immediate disqualification and regulatory reporting.

🧠 Do You Need a Calculator for Series 24?

While math is a small portion of the exam, expect questions involving:

• Markup/markdown percentages
• Net proceeds and commissions
• Spread calculations in underwriting
• Basic margin requirements

These are simple numerical questions, and the on-screen calculator is more than sufficient.

📝 Tips for Managing Math on the Exam

• Use the dry-erase board provided at the testing center to organize your work
• Practice with a basic calculator during your prep so you’re familiar with the simplicity of the test version
• Memorize key formulas (e.g., markup = (ask – bid) / bid × 100) ahead of time
• Keep calm—the math will be straightforward if you know the concepts

✅ Final Checklist for Exam Day

• Arrive early with valid photo ID
• Leave personal items—including calculators—outside the testing room
• Familiarize yourself with the on-screen tools, including the calculator and flag/review functions
• Focus more on rule interpretation and supervisory procedures—the core of Series 24
