Real Estate Commission Calculation: Step-by-Step Walkthrough
Commission problems are the most common math questions on the real estate exam — and they're also the most predictable. Every problem is some combination of: total commission, brokerage split, and agent split. If you can do basic multiplication and percentage, you can solve every commission problem on any state exam.
The Universal Commission Formula
Total Commission = Sale Price × Commission Rate. This is the only formula you ever need. Everything else (brokerage splits, agent splits, co-op deals) is just dividing or multiplying that total by a percentage.
Always work from the top down: calculate total commission first, then split between brokerages, then split between brokerage and agent.
Three Worked Examples
Question 1
A property sells for $375,000. The total commission is 6%, split 50/50 between the listing and selling brokerages. The listing agent receives 60% of the listing brokerage's portion. What's the listing agent's commission?
Total commission: $375,000 × 6% = $22,500. Listing brokerage: $22,500 ÷ 2 = $11,250. Listing agent's 60%: $11,250 × 60% = $6,750.
Question 2
A property sells for $480,000. Total commission is 5%. The brokerage receives 100% (no co-op). The agent receives a 70/30 split (agent gets 70%). What's the agent's commission?
Total: $480,000 × 5% = $24,000. Agent's 70%: $24,000 × 70% = $16,800.
Question 3
An agent's commission is $9,800 on a property that sold for $245,000. The agent received 50% of the brokerage's commission, and the brokerage received 50% of the total commission. What was the total commission rate?
Work backwards. Agent received $9,800 = 50% of brokerage's portion. Brokerage's portion = $9,800 × 2 = $19,600. Brokerage portion = 50% of total. Total = $19,600 × 2 = $39,200. Rate = $39,200 ÷ $245,000 = 16% — wait, that seems too high. Recheck: $39,200 ÷ $245,000 = 0.16. Most exam answers will land at 6%, 7%, etc. Always sanity-check your answer.

Commission FAQ
What's a typical commission rate?
5–6% is most common for residential, but rates are negotiable and vary by market. Don't assume any specific rate on exam questions — read carefully.
What's a 50/50 split?
Equal split. Two parties each receive 50% of the commission portion at that level (brokerage-to-brokerage or brokerage-to-agent).
What's a graduated commission split?
Higher production tiers earn higher agent percentages. E.g., 60/40 up to $100K, then 70/30 thereafter. Exam questions usually specify simple flat splits.
