Commission Amount
Sale Price × Commission Rate = Commission
Example
$250,000 × 6% = $15,000
Multiply the sale price by the commission rate to find the total commission earned on the transaction.
Agent Split
Total Commission × Agent Split % = Agent Share
Example
$15,000 × 60% = $9,000
The agent's share is calculated by multiplying the total commission by their split percentage with the brokerage.
Finding Sale Price from Commission
Commission ÷ Commission Rate = Sale Price
Example
$15,000 ÷ 6% = $250,000
When you know the commission earned and the rate, divide to find the original sale price.
