Real Estate Math study guide cover

Math is a small part of most real estate exams, but it is where many test takers lose easy points. The good news: a handful of formulas cover almost every question.

Commission and Splits

Commission questions often have two or three steps. Find the total, split it between brokers, then apply the agent’s share.

Formula

Commission = Sale Price × Rate

Example: $350,000 × 6% = $21,000

Loan-to-Value and Prorations

These show up in financing and closing questions. Keep the table below handy while you practice.
