Quick answer

Pearson VUE assigns seven scored National/General Sales Agent questions to Real Estate Math Calculations, one in each official area. Four test application and three test analysis. Start with the 35 core relationships, memorize 43,560 square feet per acre and 5,280 feet per mile, then use the complete reference for additional setups. These are Pass Texas study relationships, not a required formula list issued by Pearson. Check the official math outline.

Commission & Splits

Commission Amount

Sale Price × Commission Rate = Commission

$250,000 × 6% = $15,000

Agent Split

Brokerage Share × Agent Split % = Agent Share

$7,500 brokerage share × 60% = $4,500

Finding Sale Price from Commission

Commission ÷ Commission Rate = Sale Price

$15,000 ÷ 6% = $250,000

All rates and splits here are hypothetical, negotiated terms. Calculate the brokerage share before the agent share. Source

Proration

Daily Rate

Annual Amount ÷ (360 or 365) = Daily Rate

$3,650 ÷ 365 = $10/day

Party's Share

Daily Rate × Days Owned = Proration

$10/day × 180 days = $1,800

Follow the specified year length and closing-day allocation. Unpaid seller taxes usually mean seller debit/buyer credit; a buyer reimbursing the seller for a prepaid buyer expense reverses the entries. Source

Cap Rate & GRM

Capitalization Rate

Annual NOI ÷ Property Value = Cap Rate

$50,000 ÷ $500,000 = 10%

Property Value (Income Approach)

Annual NOI ÷ Cap Rate = Property Value

$50,000 ÷ 10% = $500,000

Gross Rent Multiplier

Sale Price ÷ Gross Rent = GRM

$500,000 ÷ $60,000 = 8.33

NOI is annual for cap-rate calculations. Match monthly or annual gross rent to the GRM you are using.

Property Tax

The $140,000 exemption applies to school-district tax. Use assessed value after any applicable limitation, then subtract that unit's exemptions. The $1.00 tax rate is hypothetical. Check the Comptroller guidance.

Taxable Value

Assessed Value − Applicable Exemptions = Taxable Value

$310,000 assessed − $140,000 school exemption = $170,000

Annual Property Tax

Taxable Value ÷ 100 × Tax Rate per $100 = Tax

$170,000 ÷ 100 × $1.00 = $1,700 school tax

Property Management

Effective Gross Income

Potential Gross Income − Vacancy & Collection Loss + Other Income = EGI

$120,000 − $6,000 + $2,000 = $116,000

Net Operating Income

Effective Gross Income − Operating Expenses = NOI

$116,000 − $46,000 = $70,000 NOI

Vacancy Rate

Vacant Units ÷ Total Units = Vacancy Rate

5 ÷ 100 = 5%

Occupancy Rate

Occupied Units ÷ Total Units = Occupancy Rate

95 ÷ 100 = 95%

Rent per Square Foot

Annual Rent ÷ Square Feet = Annual Rent per Sq Ft

$24,000 ÷ 2,000 = $12 per sq ft per year

NOI excludes debt service, income taxes and depreciation. A vacancy rate by unit count equals the lost-rent percentage only when rents are equal or the problem says to use it. Source

Area & Acreage

Square Footage

Length × Width = Area (sq ft)

50 ft × 100 ft = 5,000 sq ft

Acres Conversion

Square Feet ÷ 43,560 = Acres

87,120 sq ft ÷ 43,560 = 2 acres

Price per Square Foot

Price ÷ Square Footage = Price per Sq Ft

$500,000 ÷ 2,500 sq ft = $200/sq ft

Interest & Loan Costs

Simple Interest

Principal × Annual Rate × Time in Years = Interest

$200,000 × 6% × 1 year = $12,000

Monthly Interest

Loan Balance × Annual Rate ÷ 12 = Monthly Interest

$200,000 × 6% ÷ 12 = $1,000

Loan Origination Fee

Loan Amount × Fee Rate = Origination Fee

$200,000 × 1% = $2,000

Discount Points

Loan Amount × Points (as %) = Point Cost

$200,000 × 2 points (2%) = $4,000

Principal Reduction (Amortization)

Monthly P&I Payment − Monthly Interest = Principal Paid

$1,500 payment − $1,000 interest = $500 principal

Prepayment Penalty

Loan Balance × Stated Penalty Rate = Prepayment Penalty

$180,000 × 2% = $3,600

Time must be in years when the simple-interest rate is annual. Monthly interest alone is not the full mortgage payment. One point costs 1% of the loan; it does not guarantee a fixed rate reduction. Source

Loan-to-Value (LTV)

LTV Ratio

Loan Amount ÷ Property Value = LTV

$180,000 ÷ $200,000 = 90% LTV

Down Payment

Purchase Price − Loan Amount = Buyer Down Payment

$200,000 − $180,000 = $20,000

Follow the question's value basis. Fannie Mae purchase loans generally use the lower of price and appraisal; refinance loans use appraised value. Source

Seller Net & Required Price

Seller Net

Sale Price − Payoff − Selling Costs = Seller Net

$425,000 − $298,000 − $31,375 = $95,625

Required Sale Price

(Target Net + Payoff + Fixed Costs) ÷ (1 − Selling-Cost Rate) = Required Price

($85,000 + $298,000 + $3,000) ÷ 94% = $410,638.30

Buyer Cash Required

Down Payment + Unpaid Costs + Prepaids − Credits − Deposit = Cash to Close

$60,000 + $7,500 + $2,100 − $1,000 − $5,000 = $63,600

Transfer Tax (National Formula)

Sale Price ÷ Tax Unit × Rate = Transfer Tax

$300,000 ÷ $1,000 × $2 = $600

Recording Fee

Recorded Units × Fee per Unit = Recording Fee

12 pages × $5 per page = $60

Cash to close is the additional amount due after deposits and credits. Seller net is cash after payoff and costs, not gain for tax purposes. For a National transfer-tax problem, use the given rate even though Texas has no statewide fee-simple transfer tax. Source

Mortgage Qualifying Ratios

Monthly PITI

Monthly P&I Payment + Monthly Taxes + Monthly Insurance = PITI

$2,400 + $310 + $145 = $2,855/month

Front-End Ratio

Housing Payment ÷ Gross Monthly Income = Front-End Ratio

$2,576 ÷ $9,200 = 28%

Back-End Ratio

(Housing Payment + Monthly Debt) ÷ Gross Monthly Income = Back-End Ratio

($2,576 + $625) ÷ $9,200 = 34.79%

Use gross monthly income. Include other housing costs when the question supplies them. The example percentages are calculation results, not universal approval limits.

Profit, Loss & Equity

Equity

Current Value − Total Secured Debt = Equity

$420,000 − $286,000 = $134,000

Appreciation

Current Value − Purchase Price = Appreciation

$420,000 − $350,000 = $70,000

Market Value Depreciation

Original Value − Current Value = Depreciation

$350,000 − $315,000 = $35,000

Return on Investment (ROI)

Annual Return ÷ Cash Invested = ROI

$12,000 ÷ $150,000 = 8% ROI

Profit or Loss

Sale Price − Selling Costs − Acquisition & Improvement Costs = Profit or Loss

$430,000 − $20,000 − $365,000 = $45,000 profit

Adjusted Basis

Initial Basis + Capital Improvements − Depreciation = Adjusted Basis

$350,000 + $40,000 − $25,000 = $365,000

Gain Before Exclusions

Amount Realized − Adjusted Basis = Gain

$410,000 − $365,000 = $45,000 gain

For gain, amount realized is sale price minus selling expenses, before mortgage payoff. Adjusted basis accounts for depreciation allowed or allowable. Exclusions can change how much gain is taxable. Source

Comparable Sales Adjustments

Inferior Comparable

Comparable Sale Price + Adjustment = Adjusted Price

$415,000 + $12,000 = $427,000

Superior Comparable

Comparable Sale Price − Adjustment = Adjusted Price

$415,000 − $8,000 = $407,000

Adjust the comparable toward the subject: add for an inferior feature and subtract for a superior one. Do not adjust the subject instead.

Study method

Turn the formulas into points

A formula sheet only helps when you can name the setup, choose the right rate, and repair misses after mixed practice.

Use the sheet under exam pressure

1. Name the setup. Decide whether the question is commission, proration, tax, area, income math, LTV, or seller net before touching the calculator.

2. Write one line. Put the formula on your scratch board, then plug in numbers. Keep the rates and units consistent.

3. Check the final ask. Read the last sentence and answer the quantity it asks for.

4. Drill mixed math. A formula sheet is only useful when you can recognize which formula belongs to the question.

Key Numbers and Rates

1 acre: 43,560 sq ft
1 square yard: 9 sq ft
1 mile: 5,280 ft
1 section: 640 acres
Property tax: rate per $100 of taxable value
Taxable value: assessed - applicable exemptions
Homestead exemption: reduces taxable value
Transfer tax: National: use rate given; Texas: none
Proration day count: 360 or 365 (per question)
1 mill: $1 per $1,000

Check the setup

  • For simplified tax questions, use the value, applicable exemption, and rate given for that taxing unit. Do not apply a school exemption to every local tax.
  • NOI is effective gross income minus operating expenses, before debt service and income tax.
  • LTV percent plus down payment percent equals 100% only when both use the same property value.
  • Transfer-tax math is testable nationally. Use the supplied rate. Texas itself has no statewide fee-simple transfer tax.
  • GRM uses gross rent. Cap rate uses net operating income.
  • For LTV, use the stated lending-value base. Down payment is price minus the loan; cash to close also includes costs, credits and any deposit already paid.

Final 5-minute memory check

Texas property tax is a rate per $100 of taxable value.

Percent rates must become decimals before multiplying.

Prorations need the right owner days and 360/365 basis before the math.

LTV uses the lending value stated in the question. Down payment is purchase price minus the loan.

Commission: whose share are you finding?

A property sells for $320,000. The agreed total commission is 5%. The listing brokerage receives half, and its sales agent receives 70% of that share. What does the agent earn?

Check answer and explanation

$320,000 × 0.05 × 0.50 × 0.70

$5,600

The total commission is $16,000. The listing brokerage receives $8,000, then pays the agent 70% of that amount. Each percentage applies to a different base.

Watch for this: Do not take 70% of the entire commission. These are hypothetical agreed rates, not standard commission rates.

Proration: who owes whom?

Annual property taxes are $3,650, paid in arrears. Use a 365-day year. The question assigns 120 days to the seller and makes the closing day the buyer’s responsibility. What is the seller’s tax adjustment?

Check answer and explanation

$3,650 ÷ 365 × 120

$1,200 seller debit and buyer credit

The daily tax is $10. The seller owes $1,200 for the assigned ownership period. Because the buyer will pay the bill later, the seller gives the buyer a credit at closing.

Watch for this: Use the day count and closing-day instruction in the question. Do not silently switch to a 360-day year.

Cap rate: gross rent or operating income?

A property has $72,000 in annual effective gross income and $24,000 in annual operating expenses. Its value is $600,000. What is the capitalization rate?

Check answer and explanation

($72,000 − $24,000) ÷ $600,000

8%

Net operating income is $48,000. Divide it by the property value to get 0.08, then express the result as a percentage.

Watch for this: Using $72,000 would give 12%, but cap rate uses NOI. Do not deduct mortgage payments from NOI.

School tax: which exemption belongs here?

A qualifying homestead has an assessed value of $310,000 after any value limitation. Use a $140,000 school-district exemption and a hypothetical school tax rate of $1.00 per $100. No other exemptions apply. What is the annual school tax?

Check answer and explanation

($310,000 − $140,000) ÷ 100 × $1.00

$1,700

The school district taxes $170,000 of value. Dividing by 100 gives 1,700 taxable units, each charged $1.00. This calculates only the school tax, not the combined bill.

Watch for this: Do not apply the school exemption to city or county taxes. Calculate those separately using their own exemptions and rates.

LTV: what if the appraisal is lower?

A home costs $300,000 and appraises at $280,000. The question limits the loan to 80% of the lower amount. With no other financing, how much of the price must the buyer pay from their own funds, before closing costs?

Check answer and explanation

$300,000 − ($280,000 × 0.80)

$76,000

The loan is $224,000. Subtract it from the $300,000 price to find the buyer's contribution. That includes the $20,000 appraisal gap plus $56,000, or 20% of the lending value.

Watch for this: A 20% down payment on the purchase price would be only $60,000. It misses the fact that the loan uses a different value base.

Use it well

A short routine for using the sheet.

Try this routine, then spend the next session on the setups you missed. It is a study suggestion, not an official exam requirement.

Pass 1 Write it cold

Start with the core view. Cover the equations, write each relationship from memory, and circle anything that needs a peek.

Pass 2 Name the setup

Before calculating, say the category first: commission, proration, property tax, income math, area, LTV, seller net, or appraisal.

Pass 3 Drill mixed math

Use mixed practice after the sheet. The exam will not label the formula for you, so recognition matters as much as arithmetic.

Can you take formulas or a calculator into the exam?

Formula sheet: no. Pearson prohibits personal notes and reference materials in the examination room. The administrator supplies note-taking materials. Wait until the exam begins before writing on them.

Calculator: yes, if it meets Pearson's policy. Pearson VUE recommends bringing a calculator, since the test center does not provide one. Acceptable calculators are hand-held, battery or solar-powered financial calculators used in real estate, finance, accounting, and business; they may have storage capabilities but must not contain alpha (letter) keys. Calculator rules can change, so confirm the current Pearson VUE Texas Real Estate Candidate Handbook before test day. Mathematical labels such as sin and cos are allowed.

Units and rounding: memorize 43,560 square feet per acre and 5,280 feet per mile. Follow the proration basis and closing-day allocation in the question. Keep intermediate values unrounded when possible, then use the requested precision or standard rounding.

FAQ

Texas real estate exam math cheat sheet questions.

How much math is on the Texas real estate exam?

Pearson VUE's current Texas sales outline assigns 7 scored National items to Real Estate Math Calculations: 4 application questions and 3 analysis questions. The seven official subareas are property area, valuation, commission, loan financing, settlement and closing, investment, and property management.

Do I need to memorize all 43 formulas?

Pearson VUE does not publish a required formula list. Start with the 35 selected relationships in the 20-page guide, especially commission, proration, property tax, area, LTV, seller net, NOI, cap rate, and financing costs. Use the complete 43-formula web view to review additional setups and reverse calculations.

Can I rely on a cheat sheet during the Texas real estate exam?

No. Use this cheat sheet before the exam to build memory. You should be able to write the formulas from memory and recognize which formula a word problem is asking for.

What is a common Texas real estate exam math mistake?

Watch for a correct calculation using the wrong input: a tax rate applied before exemptions, a proration using the wrong year length, or gross rent substituted for NOI. Label the value, time period and units before calculating.

Is this cheat sheet enough to learn Texas real estate exam math?

Use it as a reference while you learn, then practice without it. If you can recall a formula but keep choosing the wrong one, spend the next session explaining what each word problem asks you to find before calculating.
