Is There Math on the Texas Real Estate Exam?

Yes — but the exact amount is public. The official Pearson VUE content outline allocates exactly 7 scored questions to "Real Estate Math Calculations" on the national portion — it even itemizes them (one on property area, one on valuation, one on commission, and so on). The state portion (40 questions) has no math category whatsoever — and if you're coming from another state, the state portion may be the only exam you take.

The math that does appear is straightforward — no calculus, no complex equations, no financial modeling. You're working with a handful of formulas that you can memorize in an afternoon. The goal of this guide is to show you exactly which formulas matter, walk through a real example for each, and tell you what you can safely skip.

🧮

Calculator Policy

Bring your own calculator — the test center does not provide one. Per the Pearson VUE Texas Real Estate Candidate Handbook: calculators aren't required but are recommended, and acceptable models include hand-held, battery- or solar-powered financial calculators used in real estate and finance. Storage capability is fine; what's banned is alpha character keys (phone-style ABC/DEF — math labels like "cos" don't count). One more handbook detail: a calculator malfunction won't get you extra time or a challenge, so bring one you trust with fresh batteries.

The Formulas That Show Up

These are the seven math categories that appear on the national portion of the Texas real estate salesperson exam. Learn all of them — each one is fair game.

Commission Calculations
Most commonly tested math on the exam
Total Commission = Sales Price × Commission Rate
Agent's Share = Total Commission × Agent's Split %
Broker's Share = Total Commission × Broker's Split %
Worked Example
A home sells for $380,000 at a 6% commission rate.
Total commission = $380,000 × 0.06 = $22,800
The listing agent and buyer's agent split it 50/50:
Each side receives = $22,800 ÷ 2 = $11,400
The listing agent is on a 70/30 split with their broker:
Agent keeps = $11,400 × 0.70 = $7,980
The exam may ask you to work this calculation in any direction — given the sales price and rate to find commission, or given the commission to find what the agent nets after splits. Practice both directions.
📅
Proration
Dividing costs between buyer and seller at closing
Monthly Rate = Annual Amount ÷ 12
Daily Rate = Monthly Rate ÷ 30
Prorated Amount = Daily Rate × Number of Days
Worked Example
Annual property taxes are $3,600. Closing is March 20th.
The seller owned the property through March 20 and owes their prorated share.
Monthly rate = $3,600 ÷ 12 = $300/month
Daily rate = $300 ÷ 30 = $10/day
Jan + Feb = 2 full months = $600. March 1–20 = 20 days = $200.
Seller's prorated share = $600 + $200 = $800 credit to buyer
Most real estate courses teach proration using a 360-day year / 30-day month — that's the method above, and the one you'll most likely see on the exam. That said, always follow whatever calendar method the question itself specifies. If it says "use a 365-day year," use 365. If it gives no instruction, default to 360/30. Proration questions can involve property taxes, rent, HOA fees, or homeowner's insurance — the math process is always the same regardless of the calendar method.

Area & Square Footage
Memorize these two numbers cold
Area = Length × Width
1 acre = 43,560 sq ft
1 mile = 5,280 ft
1 section = 640 acres
Worked Example
A rectangular lot is 150 ft × 200 ft. How many acres is it?
Area = 150 × 200 = 30,000 sq ft
Acres = 30,000 ÷ 43,560 = 0.69 acres
You will not be given conversion factors on the exam — you need to have 43,560 and 5,280 memorized. That's non-negotiable. Everything else in this category is just multiplication and division.
📈
Appreciation & Depreciation
Value over time — and tax write-offs
Appreciated Value = Original Value × (1 + rate)
Depreciated Value = Original Value × (1 − rate)

Annual Tax Depreciation (residential) = Building Value ÷ 27.5
Annual Tax Depreciation (commercial) = Building Value ÷ 39
Worked Example — Appreciation
A home is worth $320,000 and appreciates 5% in one year.
New value = $320,000 × 1.05 = $336,000
Worked Example — Tax Depreciation
A rental property's building (not land) is worth $275,000.
Annual depreciation = $275,000 ÷ 27.5 = $10,000/year
Land is never depreciated — only the structure. If a question gives you a total property value, you may need to separate out the land value first before calculating depreciation on the building portion.
🏢
NOI & Income Approach to Value
How investors value income-producing properties
NOI = Gross Rental Income − Vacancy Loss − Operating Expenses
Value = NOI ÷ Cap Rate
Cap Rate = NOI ÷ Value
Worked Example
A property grosses $72,000/year. Vacancy is 5%. Operating expenses are $18,000.
Vacancy loss = $72,000 × 0.05 = $3,600
NOI = $72,000 − $3,600 − $18,000 = $50,400
At a 7% cap rate, estimated value = $50,400 ÷ 0.07 = $720,000
NOI does not include mortgage payments (debt service) — that's a common trick. Operating expenses include taxes, insurance, maintenance, and management fees, but not the loan payment.
🏘️
Gross Rent Multiplier (GRM)
Quick way to estimate a rental property's value
GRM = Sales Price ÷ Gross Monthly Rent
Estimated Value = GRM × Gross Monthly Rent
Worked Example — Finding GRM
A property sells for $300,000 and rents for $2,000/month.
GRM = $300,000 ÷ $2,000 = 150
Worked Example — Estimating Value
Similar properties in the area have a GRM of 150. A subject property rents for $1,800/month.
Estimated value = 150 × $1,800 = $270,000
GRM uses gross monthly rent — not annual, and not net. Watch the question carefully: if the rent given is annual, divide it by 12 to convert to monthly rent before plugging it into the formula.
🏦
Loan-to-Value Ratio (LTV)
How much of the property is financed vs. owned
LTV = Loan Amount ÷ Appraised Value
Loan Amount = LTV % × Appraised Value
Down Payment = Appraised Value − Loan Amount
Worked Example
A home appraises at $400,000. The buyer puts 20% down (80% LTV loan).
Loan amount = 0.80 × $400,000 = $320,000
Down payment = $400,000 − $320,000 = $80,000
When the sales price is lower than the appraised value, lenders use the lower of the two to calculate LTV — a detail that can appear in exam questions. Also: LTV above 80% typically triggers a requirement for private mortgage insurance (PMI).
✓ What You Can Stop Worrying About
  • Amortization schedules or monthly payment calculations — you won't need to compute these by hand
  • Compound interest or time-value-of-money formulas
  • Statistical analysis or appraisal regression models
  • Complex tax calculations beyond basic depreciation
  • Financial-calculator wizardry — the mortgage factors and amortization functions those keys exist for are provided or unnecessary on this exam

How to Study the Math

The biggest mistake people make is reading through formulas without actually working problems. Here's what actually works:
