The Real Estate Math You Actually Need for the Texas Exam

Real estate math has a reputation for being the scariest part of the exam, which makes it worth saying plainly: it's a small slice. Seven of the National portion's 80 scored questions are math — under 9% of that half of the exam. But because you get zero formula sheet and have to know two specific numbers cold, it's worth treating those seven questions with more preparation than their share alone would suggest.

What the math section actually covers

TREC and Pearson VUE's own content outline breaks the math section into seven one-item categories:

• Property area calculations — square footage, acreage totals.
• Property valuation — comparative market analysis, net operating income, capitalization rate, equity, establishing a listing price, assessed value and property taxes.
• Commission/compensation — splitting commission between brokers and agents.
• Loan financing costs — interest, loan-to-value ratio, fees, amortization, discount points, prepayment penalties.
• Settlement and closing costs — down payment, monthly PITI (principal, interest, taxes, insurance), net to the seller, cost to the buyer, prorated items, debits and credits, transfer tax and recording fees.
• Investment — return on investment, appreciation, depreciation, tax implications.
• Property management calculations — budgeting and rental calculations.

Each category is worth exactly one item, so this isn't a section that rewards memorizing formulas for the categories you find easy and skipping the rest — every category shows up.

The two numbers you have to know cold

Pearson VUE states this directly: the test center does not give you a reference sheet, and two specific conversions are explicitly called out as things you're expected to have memorized:

• 43,560 square feet per acre
• 5,280 feet per mile

Everything else in the math section is a calculation built from a scenario in the question itself — there's no separate formula sheet, so the two conversions above are effectively the only "must-memorize" numbers, versus the many formulas you apply using numbers the question gives you.

Proration questions specify their own rules — read carefully

Proration items (splitting a cost like property tax or HOA dues between buyer and seller at closing) are a common trap not because the math is hard, but because the rules vary and the question always tells you which rule to use — if you don't read that part, you'll do correct math against the wrong assumption. Specifically, any proration question will state:

• Whether to calculate on a 360-day or 365-day year.
• Whether the day of closing belongs to the buyer or the seller for proration purposes.

Both of these change the answer. Neither is a fixed rule you can memorize once and apply to every question — the exam is testing whether you read and apply the stated assumption, not whether you've picked a favorite convention.

A calculator is allowed — reading the scenario is the actual skill

You're allowed an on-screen or physical calculator for the math section, so raw arithmetic isn't really the bottleneck. The actual skill being tested is translating a word-problem scenario (a purchase price, a loan amount, a closing date, a commission split) into the right formula and the right order of operations — which is exactly why math questions tend to reward practice with realistic scenarios more than they reward re-reading formula definitions.

Where this fits in your prep

Because math questions are scenario-based rather than recall-based, they're one of the areas where working practice problems does more than reviewing notes. Our National lessons include a Real Estate Calculations section built the same way the exam tests it — one worked scenario per concept, not a formula list to memorize in isolation.
