Commission and Split Calculations for the Texas Real Estate Exam

Start Here

Commission math is one of the most testable real estate math skills because it looks simple and then quietly adds layers.

The first layer is easy:

Commission = sale price x commission rate

The problem starts when the question does not stop there.

It may ask for:

• Total gross commission.
• Listing-side commission.
• Buyer-side commission.
• Agent share.
• Broker share.
• Referral fee.
• Net-to-agent.
• Net-to-seller.
• Sale price from commission.
• Commission rate from commission and price.

That is why commission questions are less about one formula and more about sequence.

You solve the right number only if you know which layer the question is asking for.

What Commission Math Appears On The Texas Real Estate Exam?

Pearson VUE's current Texas sales content outline lists Real Estate Math Calculations on the National/General portion. Under that math category, Pearson specifically lists "Commission/compensation."

That does not mean every candidate gets the same commission question. Pearson's handbook explains that exams use multiple forms and are built from content outlines. The safe study move is to understand the type of calculation, not to hunt for copied questions.

Commission math can also show up near other topic areas:

This article uses original educational examples. They are not copied exam questions.

The Core Commission Formula

The basic formula is:

Commission = sale price x commission rate

If the property sells for $500,000 and the commission rate stated in the problem is 5%, then:

$500,000 x 0.05 = $25,000

The commission is $25,000.

The rate must be converted from a percent to a decimal:

Do not type 5 for 5%. Type 0.05.

The Commission Ladder

Most mistakes happen because candidates skip a rung.

Use this order:

The exact path depends on what the question asks.

But the order matters.

If you calculate agent split before finding the side commission, you may use the wrong base.

Formula Sheet

Use this as your commission math cheat sheet.

The phrase "applicable commission" matters for referral fees.

A referral fee might be based on:

• Total commission.
• One side of the commission.
• The agent's gross commission.
• A flat dollar amount.

Use the base the question gives. Do not invent one.

Question Wording Translator

Commission questions often hide the target inside ordinary wording. Translate the words before calculating.

The phrase "before" or "after" can change the whole problem.

If a problem feels messy, write the target as one phrase before touching the calculator:

• Total commission.
• Listing side.
• Buyer side.
• Agent gross.
• Referral fee.
• Agent net.
• Seller net.

That tiny pause prevents most commission math mistakes.

The Base-Number Rule

Every percentage needs a base.

Ask: "Percent of what?"

The base is not always the biggest number in the problem. It is the number the percentage applies to.

Gross Commission Examples

Example 1: Basic Gross Commission

A property sells for $450,000. The commission rate stated in the problem is 5%. What is the gross commission?

Sale price:

$450,000

Rate:

5% = 0.05

Commission:

$450,000 x 0.05 = $22,500

Answer: $22,500.

Example 2: Different Rate

A property sells for $725,000. The stated commission rate is 4%. What is the gross commission?

$725,000 x 0.04 = $29,000

Answer: $29,000.

Example 3: Commission Rate From Dollars

A property sells for $600,000 and the total commission is $30,000. What is the commission rate?

Rate = commission / sale price

$30,000 / $600,000 = 0.05

Answer: 5%.

Example 4: Sale Price From Commission

A broker receives $24,000 in total commission at a 6% rate. What was the sale price?

Sale price = commission / rate

$24,000 / 0.06 = $400,000

Answer: $400,000.

Side Split Examples

Side split means dividing total commission between sides, usually listing side and buyer side.

Do not assume the side split is equal unless the question says it is equal.

Example 5: Equal Side Split

A property sells for $500,000 at a 6% commission. The commission is split equally between the listing side and buyer side. What does each side receive?

Total commission:

$500,000 x 0.06 = $30,000

Each side:

$30,000 / 2 = $15,000

Answer: each side receives $15,000.

Example 6: Unequal Side Split

A property sells for $500,000 at a 6% commission. The listing side receives 55% of the total commission, and the buyer side receives 45%. What does the listing side receive?

Total commission:

$500,000 x 0.06 = $30,000

Listing side:

$30,000 x 0.55 = $16,500

Answer: $16,500.

Example 7: Buyer Side

Using the same facts, what does the buyer side receive?

Buyer side:

$30,000 x 0.45 = $13,500

Answer: $13,500.

Quick check:

$16,500 + $13,500 = $30,000

The sides add back to the total commission.

Broker Split And Agent Split Examples

After the side split, the problem may ask how much the agent or broker receives.

This is where candidates often use the wrong base.

The agent split is usually applied to the side commission, not the full sale price and not the full commission, unless the question says otherwise.

Example 8: Agent Split

A listing side commission is $15,000. The listing agent receives 70% of that side. What is the agent's gross commission?

$15,000 x 0.70 = $10,500

Answer: $10,500.

Example 9: Broker Share

A buyer side commission is $12,000. The agent receives 75%, and the broker keeps the remaining 25%. What is the broker share?

$12,000 x 0.25 = $3,000

Answer: $3,000.

Alternative:

Agent share = $12,000 x 0.75 = $9,000

Broker share = $12,000 - $9,000 = $3,000

Both methods work.

Example 10: Full Layered Split

A property sells for $640,000. Total commission is 5%. The commission is split equally between sides. The buyer agent receives 80% of the buyer side. What is the buyer agent's gross commission?

Step 1: Total commission.

$640,000 x 0.05 = $32,000

Step 2: Buyer side.

$32,000 / 2 = $16,000

Step 3: Agent gross.

$16,000 x 0.80 = $12,800

Answer: $12,800.

Referral Fee Examples

Referral fees add another layer.

The exam-style trap is the base.

A referral fee may be based on the agent's gross commission, a side commission, total commission, or a stated flat amount. Read the wording.

Example 11: Referral Fee Based On Agent Gross

An agent's gross commission is $10,000. The agent owes a 25% referral fee. What is the referral fee?

$10,000 x 0.25 = $2,500

Answer: $2,500.

Example 12: Net After Referral Fee

Using the same facts, what is the agent's net after the referral fee?

Agent gross:

$10,000

Referral fee:

$2,500

Net:

$10,000 - $2,500 = $7,500

Answer: $7,500.

Example 13: Referral Fee Based On Side Commission

A side commission is $18,000. A 20% referral fee is paid from that side before the agent split. What is the referral fee?

$18,000 x 0.20 = $3,600

Answer: $3,600.

If the problem then asks for agent split after referral, subtract referral first, then split the remaining amount if the wording says so.

Net-To-Agent Examples

Net-to-agent questions ask what the agent actually keeps after stated deductions.

Only subtract deductions the question gives.

Do not subtract taxes, desk fees, insurance, marketing, or transaction fees unless the problem tells you to.

Example 14: Net To Agent After Referral

A property sells for $500,000 at 6% total commission. The commission is split equally between sides. The listing agent receives 70% of the listing side and owes a 25% referral fee based on the agent's gross commission. What is the listing agent's net after the referral fee?

Step 1: Total commission.

$500,000 x 0.06 = $30,000

Step 2: Listing side.

$30,000 / 2 = $15,000

Step 3: Agent gross.

$15,000 x 0.70 = $10,500

Step 4: Referral fee.

$10,500 x 0.25 = $2,625

Step 5: Net to agent.

$10,500 - $2,625 = $7,875

Answer: $7,875.

Example 15: Net To Agent With Flat Deduction

An agent's gross commission is $8,400. The agent pays a $300 transaction fee and no referral fee. What is the net to agent?

$8,400 - $300 = $8,100

Answer: $8,100.

Example 16: Net To Agent With Multiple Deductions

An agent's gross commission is $12,000. The agent owes a 20% referral fee based on gross commission and a $450 transaction fee. What is the net?

Referral fee:

$12,000 x 0.20 = $2,400

Net:

$12,000 - $2,400 - $450 = $9,150

Answer: $9,150.

Net-To-Seller Basics

Net-to-seller problems are related to commission math because commission is usually a seller debit in simplified exam math.

The basic formula is:

Seller net = sale price - seller debits + seller credits

Common seller debits in a simplified math question:

• Commission.
• Loan payoff.
• Seller closing costs.
• Seller-paid concessions, if stated.
• Seller share of prorated expenses, if stated.

Common seller credits:

• Buyer reimbursement, if stated.
• Proration credit, if stated.

Example 17: Seller Net Before Prorations

A property sells for $420,000. The seller pays a 5% commission, has a $260,000 loan payoff, and pays $3,500 in other seller closing costs. What is the seller's net before prorations?

Commission:

$420,000 x 0.05 = $21,000

Seller net:

$420,000 - $21,000 - $260,000 - $3,500 = $135,500

Answer: $135,500.

Example 18: Seller Net With A Credit

A property sells for $390,000. Seller debits are $24,000 in commission, $210,000 loan payoff, and $4,000 in closing costs. The seller also receives a $900 proration credit. What is the seller net?

$390,000 - $24,000 - $210,000 - $4,000 + $900 = $152,900

Answer: $152,900.

The credit increases the seller's net.

Reverse Commission Problems

Reverse questions ask for the sale price or rate instead of the commission.

Use the T-bar / circle method:

Part = whole x rate
Whole = part / rate
Rate = part / whole

Related page: The T-bar / circle method explained

Example 19: Find Sale Price

A broker received $21,000 in commission at a 6% commission rate. What was the sale price?

$21,000 / 0.06 = $350,000

Answer: $350,000.

Example 20: Find Rate

A property sold for $480,000 and the total commission was $24,000. What was the commission rate?

$24,000 / $480,000 = 0.05

Answer: 5%.

Notice that Questions 14 and 15 produced the same final number because the same percentages were multiplied against the same base in sequence. That will not always happen if the question changes the base or adds flat fees.

Common Mistakes

Mistake 1: Assuming A Standard Commission

Do not assume a standard commission rate.

Use the rate stated in the question. If the question says 5%, use 5%. If it says 4%, use 4%. If it gives total commission and asks for the rate, calculate the rate.

Mistake 2: Applying Agent Split To The Sale Price

Agent split is usually applied to the side commission, not the sale price.

Wrong setup:

$500,000 x 0.70

Right setup, if total commission is 6%, split equally, and agent split is 70%:

$500,000 x 0.06 = $30,000

$30,000 / 2 = $15,000

$15,000 x 0.70 = $10,500

Mistake 3: Splitting Before Finding Total Commission

If the question gives a sale price and a commission rate, find total commission first.

Then split.

Sale price is not usually split between brokers. Commission is.

Mistake 4: Using The Wrong Referral Base

Referral fees depend on wording.

The problem may say:

• Referral fee based on total commission.
• Referral fee based on side commission.
• Referral fee based on agent gross.
• Referral fee paid before split.
• Referral fee paid after split.

Read the base carefully.

Mistake 5: Confusing Broker Share And Agent Share

If the agent receives 70%, the broker keeps 30%, unless the question states another deduction or structure.

If the broker keeps 25%, the agent receives 75%.

The two should add to 100% when they are describing the same commission bucket.

Mistake 6: Forgetting Loan Payoff In Seller Net

Seller net problems often include loan payoff.

If the seller has a mortgage payoff, subtract it unless the question tells you it has already been handled.

Mistake 7: Subtracting Costs Not Given

Do not subtract taxes, marketing, desk fees, insurance, or brokerage costs unless the question gives them.

Exam math uses the facts stated in the question.

Where This Fits In The Texas Math Cluster

Commission calculations connect to several other math topics.

FAQ

How do you calculate real estate commission?

Multiply the sale price by the commission rate stated in the question. For example, a $500,000 sale at 5% commission produces $25,000 in gross commission.

What is the formula for commission on the Texas real estate exam?

The core formula is commission = sale price x commission rate. You may also need side commission = total commission x side split, agent gross = side commission x agent split, and net to agent = agent gross minus stated deductions.

Should I assume a 6% commission?

No. Do not assume any standard commission rate. Use the rate stated in the question. This article uses different rates for practice only, not as a statement about market practice.

What is a side split?

A side split divides total commission between sides, often the listing side and buyer side. If the problem says the commission is split equally, each side receives half. If it gives a different percentage, use that percentage.

What is an agent split?

An agent split is the portion of a commission bucket the agent receives under the facts stated in the question. In math examples, it is often applied to the side commission.

What is a broker split?

A broker split is the portion of the commission bucket kept by the broker under the facts stated in the question. If the agent receives 75% and no other facts are given, the broker share is usually the remaining 25% of that same bucket.

How do referral fees work in commission math?

A referral fee is usually a percentage of a stated commission amount. The key is identifying the base. The fee may be based on total commission, side commission, agent gross, or another amount stated in the problem.

How do you calculate net-to-agent?

Start with the agent's gross commission, then subtract only the deductions stated in the question, such as a referral fee or transaction fee.

How do you calculate net-to-seller?

Start with sale price, subtract seller debits such as commission, loan payoff, and seller closing costs, then add seller credits if stated. Use only the facts in the question.
