Can You Use a Calculator on the Real Estate Exam?
Yes — but not your own. Every state real estate exam provides a basic on-screen calculator at your testing station. You cannot bring a personal calculator, phone, or any external device into the testing room.
The on-screen calculator handles the four basic operations and percentage. It doesn't have memory keys, financial functions (like PMT or PV), or scientific operations. Practice your math on a basic calculator before test day.
What the On-Screen Calculator Does
The basic calculator has four functions (add, subtract, multiply, divide) plus a percentage key. It opens in a small popup window during the exam — you click an icon or button on the exam interface to access it.
It does NOT have memory keys (M+, M-, MR, MC), programmable functions, financial functions (PMT, FV, PV, N, I/Y), or scientific operations (exponents, square roots, logs).
You'll also receive a whiteboard with a dry-erase marker (or sometimes scratch paper) for working through multi-step calculations. Anything you write must be turned in at the end of the exam.
What You Cannot Bring
Your own calculator (any type — basic, scientific, financial, programmable)
Phone, smartwatch, fitness tracker, earbuds, or any electronic device
Notes, books, scratch paper of your own
Pens, pencils, highlighters
Bag, wallet, or any personal items into the testing room (lockers are provided)
What 4-Function Math Looks Like
Three real estate math problems that demonstrate basic calculator math. Notice how each problem reduces to one or two basic operations.
Question 1
A property sells for $325,000. The total commission is 6%, split 50/50 between the listing and buying brokerages. The agent at the listing brokerage receives 60% of the listing brokerage's portion. What is the agent's commission?
Total commission: $325,000 × 6% = $19,500. Listing brokerage's half: $19,500 ÷ 2 = $9,750. Agent's 60% of that: $9,750 × 60% = $5,850.
Question 2
A buyer obtains an 80% Loan-to-Value (LTV) loan on a property appraised at $250,000. What is the loan amount?
Loan amount = $250,000 × 80% = $200,000. (Single multiplication, easily done on a 4-function calculator.)
Question 3
Annual property taxes are $4,800. The seller has paid the full year. Closing is on July 1. The buyer reimburses the seller for the unused days, using a 365-day year. How much does the buyer reimburse?
Daily tax: $4,800 ÷ 365 = $13.15. Days from July 1 through Dec 31 = 184. Reimbursement: $13.15 × 184 = $2,419.60 (typical rounded answer).
How to Practice for On-Screen Calculator Math
Practice with a basic 4-function calculator only — not your phone, not a financial calculator. Train yourself to break complex problems into the basic operations the on-screen calculator supports.
Most candidates who fail real estate math do so because their practice tools were too capable. They got used to PMT or amortization shortcuts on a financial calculator and couldn't reproduce the steps when those shortcuts disappeared.

Calculator FAQ
Can I bring my own calculator if it's just a basic 4-function?
No. The vast majority of testing centers prohibit any personal calculator regardless of type. You must use the on-screen calculator provided by the testing software.
What if the on-screen calculator stops working?
Raise your hand and tell the proctor. They can restart your exam interface. The exam clock is typically paused during any technical issue.
Are there any states that allow personal calculators?
Extremely rare. A few states historically allowed approved-model handheld calculators, but PSI and Pearson VUE testing centers almost universally provide on-screen calculators only as of 2026.
