Tips & Best Practices
Write all math formulas on your scratch paper as a "brain dump" in the first two minutes of the exam — this eliminates the stress of trying to recall them under pressure
Practice each formula with at least 5-10 different problems until you can solve them automatically without thinking about the steps
Remember the T-bar method (or "is over of") for percentage problems: Part / Whole = Percentage — this single framework solves commission, proration, and equity questions
Pay attention to whether a question asks for monthly or annual amounts — a common trap is calculating an annual figure when the question asks for monthly, or vice versa
Frequently Asked Questions
The essential formulas include: Commission = Sale Price x Rate, Net to Seller = Sale Price - Commission, GRM = Price / Gross Annual Rent, Cap Rate = NOI / Value, LTV = Loan / Value, Proration = Annual Amount / 365 (or 360) x Days, Area = Length x Width, and Equity = Value - Debt. Most exams also test tax assessment calculations and basic interest computations.
Math questions typically represent 10-15% of the exam, or roughly 10-20 questions depending on your state. While this may seem like a small portion, these questions are among the easiest to get right with proper preparation because they follow predictable formulas. Mastering the math is one of the highest-return investments of your study time.
Most states provide an on-screen calculator within the exam software, and some testing centers provide a basic handheld calculator. You typically cannot bring your own calculator. Practice with a basic calculator (not a scientific or financial calculator) during your study sessions so you are comfortable with the limited functionality available on exam day.
