The DRE Website Says Two Different Things
If you've done any research on what you can bring to the CA real estate exam, you may have stumbled across something confusing: the California Department of Real Estate's own website appears to contradict itself on calculators — on the same page.
On one hand, an older regulation listed on the DRE's exam page states that non-programmable calculators are permitted. On the other hand, the same page's current "Examination Control Information" section explicitly lists calculators as a prohibited item. Same URL. Two different answers.
The regulation citing slide rules is the giveaway — that language predates computerized testing entirely. The California real estate exam is now administered at DRE testing centers on computers, and the current operational policy is clear: no calculators.
What a CA Real Estate School Says
Chamberlain Real Estate School's FAQ for the California exam is equally direct on this point:
Their FAQ also lists the full set of prohibited items: backpacks, briefcases, suitcases, food, drink, study materials, portable computers, programmable calculators, and cell phones. The pattern is consistent — nothing that could be used to store or retrieve information is permitted in the exam room.
No Calculations — But Math Concepts Still Matter
Here's where it's worth being more precise than some sources are: the California real estate exam does not ask you to perform math calculations — there's no question where you'll be punching numbers into a calculator to arrive at a dollar figure. That's what makes the calculator ban essentially a non-issue in practice.
However, math concepts and formulas absolutely appear on the CA exam. You won't need to calculate a commission to the penny, but you may be asked to identify the correct formula, interpret a loan-to-value ratio, or understand how capitalization rate relates to property value. The difference is conceptual understanding vs. active number-crunching.
Think of it this way: you need to know what the formulas are and how they work — not necessarily how to compute them by hand. The exam tests whether you understand real estate math, not whether you can do long division.
Key CA Real Estate Math Formulas to Know
These are the formulas most commonly tested on the California real estate salesperson exam. You won't need a calculator to answer questions about them — but you do need to know what they are and when they apply.
Leave the Calculator at Home
Do not bring a calculator to your California real estate exam. The current DRE policy is clear — calculators are on the prohibited items list — even if an outdated regulation on the same page suggests otherwise. You won't need one anyway. The exam tests real estate concepts, not arithmetic.
What you should do instead is make sure you have the key math formulas memorized well enough to recognize them and apply them conceptually. That's what the CA exam actually tests — and it's a much more achievable goal than learning to crunch numbers by hand.
