Real Estate Exam Cheat Sheet: Formulas and Facts to Memorize
By the AgentExamHub team | Updated July 15, 2026
A word on the name: this is a study reference, not a way around the exam. You can’t bring notes into a PSI or Pearson VUE testing center, personal reference materials are grounds for disqualification, so “cheat sheet” here means the condensed set of formulas and facts worth memorizing cold before test day, the same content most state content outlines group under “Real Estate Calculations.”
Every state’s exam draws its math questions from roughly the same handful of formulas. Georgia’s own PSI content outline, for example, groups its calculations section into seller’s net proceeds, buyer funds needed at closing, prorations, transfer fees, and PITI, plus a general-concepts group covering equity, cap rate, loan-to-value, and discount points, which lines up closely with what other states test.
The core formulas, in one table
| Calculation | Formula | Notes |
|---|---|---|
| Commission | Sale price x commission rate | Split further by brokerage/agent percentage if the question specifies a split. |
| Simple interest | Principal x rate x time | Time is usually expressed in years or a fraction of a year. |
| Loan-to-value (LTV) | Loan amount divided by (appraised value or sale price, whichever is lower) | Lenders use the lower of the two figures, not automatically the sale price. |
| Area (rectangle) | Length x width | Convert to square feet before computing price per square foot. |
| Area (triangle) | 1/2 x base x height | Common in irregular-lot valuation questions. |
| Gross rent multiplier (GRM) | Property price divided by gross annual (or monthly) rent | Lower GRM generally signals faster payback from rental income. |
| Capitalization rate | Net operating income divided by property value | Rearrange to solve for value or NOI depending on what the question gives you. |
| Proration (per diem) | Annual expense divided by days in year, multiplied by days owned | Watch whether the question specifies a 360-day or 365-day method; state and local convention varies. |
| Points | 1 point = 1% of loan amount | Each point is a flat fee, not a percentage of the purchase price. |
| Seller’s net | Sale price minus (commission plus closing costs plus payoff amounts) | Work backward from the final target if the question gives a desired net instead. |
What trips people up on proration questions
Proration questions cause more errors than any other calculation type, not because the math is hard, but because the day-count convention isn’t standardized. Some states and closing practices use a 360-day year (12 equal 30-day months) for simplicity, others use the actual 365-day calendar. A practice-exam or textbook proration answer key that doesn’t state which convention it used is incomplete; if your own state’s exam content outline or course materials don’t specify, ask your instructor which method your state’s questions use before test day, since assuming the wrong convention changes every proration answer by a small but real margin.
What non-math facts are worth memorizing cold?
Beyond formulas, a short list of definitions and rules shows up disproportionately often across state exams:
- Fee simple is the most complete form of ownership; a life estate ends when the named person dies.
- Joint tenancy includes automatic right of survivorship; tenancy in common does not.
- A void contract has no legal effect from the start; a voidable contract is valid until one party cancels it.
- Fiduciary duties an agent owes a client typically include loyalty, obedience, disclosure, confidentiality, accounting, and reasonable care, remembered by some instructors with the mnemonic OLDCAR.
- Steering and blockbusting are both Fair Housing Act violations tied to discriminatory conduct, not identical acts.
- A general warranty deed guarantees clear title against defects from any period of ownership; a quitclaim deed guarantees nothing.
How to actually use this before test day
Memorizing a formula list the night before doesn’t work as well as most candidates hope, because exam math questions rarely hand you the formula in the wording; they give you a scenario and expect you to recognize which formula applies. Work the formula in both directions (solve for value given rate and income, and solve for rate given value and income) so you’re not thrown when a question rearranges the variables you’re used to seeing.
Run at least one full timed math section using the AgentExamHub practice quiz tool so you’re applying these formulas under time pressure, not just recognizing them on a printed page, and if proration or appraisal math is your weak spot specifically, the AgentExamHub free study guide walks through worked examples of each formula above with full step-by-step solutions.
FAQ
Can I bring a cheat sheet into the real estate exam? No. Personal reference materials of any kind are prohibited at PSI and Pearson VUE test centers and are grounds for disqualification if found during check-in. This page is a study aid to memorize before test day, not something to bring with you.
What’s the most commonly tested real estate math formula? Commission calculations and loan-to-value ratios appear across nearly every state’s content outline, alongside prorations, which candidates report as the formula type most likely to trip them up due to day-count convention differences.
Is real estate exam math hard? The formulas themselves are basic arithmetic, no algebra or calculus. What makes math questions feel hard is recognizing which formula a word problem calls for, which is a practice problem, not a formula-memorization problem.
Do all states use the same day-count convention for prorations? No. Some use a 360-day year, others use the actual 365-day calendar, and the convention isn’t always stated explicitly in every practice resource. Confirm which method your state’s course materials and exam use before you rely on a single method.
Will a calculator be provided during the exam? Most states provide an on-screen calculator and prohibit personal calculators, though a handful of states allow simple non-programmable personal calculators. Check your own state’s current candidate handbook, since this rule varies.
Bottom line: the exam draws from roughly ten recurring formulas, so memorize each one in both directions and practice recognizing which formula a scenario calls for, since that recognition step, not the arithmetic itself, is what actually separates a fast right answer from a stalled-out guess.
