How Much Math Is on the NY Real Estate Exam?

Expect roughly 8 to 12 questions out of 75 — around 10% of the exam. It is the most predictable section on the test, and the one candidates most often surrender without a fight.

How many math questions are on the exam?

The New York State Salesperson exam is 75 multiple-choice questions in 90 minutes, and you need 70% — 53 correct — to pass. Real estate math typically accounts for somewhere around 8 to 12 of those questions.

That number matters more than it looks. If you write off math entirely, you are starting the exam having already conceded roughly a tenth of it. You then need about 53 of the remaining 63–67 questions correct, which turns a comfortable margin into a tight one.

The math that actually shows up

Despite how open-ended it feels, the exam draws from a small, stable set of calculation types. Learn these six families and you have covered nearly all of it.

Two more appear occasionally: property tax mill rates and simple appreciation or depreciation over a period. Both are straightforward percentage work once you know the setup.

Is the math hard?

Not mathematically. There is no algebra beyond rearranging a simple equation, no geometry past length × width, and no calculus of any kind. Everything is arithmetic and percentages.

What makes it feel hard is that the questions are written as short stories rather than equations. The difficulty is in translating the words into numbers, not in the arithmetic itself. A question rarely says “calculate the commission” — it says a home sold, at a rate, split between two brokerages, and the agent is on a 60/40 with their broker, and asks what the agent takes home.

Can you bring a calculator?

Policy on calculators is set by the state and the testing vendor, and it can change, so confirm the current rule in eAccessNY when you book rather than trusting anything you read online — including this page. What is consistently true: a phone is never acceptable as a calculator, and personal items are generally stored outside the testing room.

Practically, this means you should practice as if you may be doing some of it by hand. Long multiplication of a sale price by a decimal rate is worth being comfortable with.

A method that works under time pressure

With 75 questions in 90 minutes you have about 72 seconds per question. Math questions take longer than average, which is fine as long as you are not also solving them inefficiently.

1. Write the numbers down as you read. Do not hold them in your head while parsing a three-sentence scenario.
2. Identify what is being asked before you calculate anything. Circle the party: total, brokerage, or agent.
3. Solve the whole first, then divide it. Almost every commission question is total → split → split again. Doing it in that order prevents compounding errors.
4. Convert percentages once. 6% becomes 0.06 at the start, not repeatedly mid-calculation.
5. Sanity-check the magnitude. A 6% commission on a $500,000 home is $30,000 — if you get $3,000 or $300,000, you slipped a decimal.
6. If it takes more than ~90 seconds, flag it and move on. Come back after you have banked the questions you know.

Mistakes that quietly cost points

• Calculating points on the sale price. Discount points are a percentage of the loan amount, not the purchase price. This is one of the most reliably missed questions on the exam.
• Stopping at the total commission. If the question asks what the agent earns, the total is only step one of three.
• Mixing up cap rate and GRM. Cap rate uses net operating income; gross rent multiplier uses gross rent. The words “net” and “gross” are doing the work.
• Prorating with the wrong day count. Know whether the question uses a 365-day year or a 360-day banker’s year, and whether the seller owns the day of closing.
• Answering the reciprocal. LTV is loan divided by value. Value divided by loan is a different number and it is often on the answer sheet.

The only thing that actually fixes it

Reading formulas does not build the skill. Working problems does. Do ten commission questions in a row and the three-step structure stops being something you reason about and starts being something you recognise.

Two free things on this site will help: the real estate math calculator, which shows every step rather than just the answer, and the math formula cheat sheet, which is also available as a printable PDF.

Use the calculator to check your work and to see the method — then do the next problem on paper. You will not have it on exam day, and the exam is testing whether you can run the method.
