Real estate transactions involve various professionals, with realtors playing a crucial role in facilitating the buying and selling of properties. Their compensation typically comes in the form of a commission, a percentage of the final sale price. This calculator helps demystify how realtor commissions are calculated in a standard transaction.
How the Commission is Calculated
The total commission is usually split between the listing agent (who represents the seller) and the buyer's agent (who represents the buyer). The overall commission rate is agreed upon by the seller and their listing agent, and this rate is then typically shared with the buyer's agent's brokerage.
The formula used by this calculator is straightforward:
Calculate Total Commission Amount: This is done by multiplying the Property Sale Price by the sum of the Listing Agent Commission Rate and the Buying Agent Commission Rate (expressed as decimals).
Mathematically:
Total Commission = Sale Price × ( (Listing Rate / 100) + (Buying Rate / 100) )
Breakdown of Commissions
While this calculator provides the total commission, it's important to understand that this amount is then further divided:
Listing Agent's Share: Typically, a portion of the total commission goes to the listing agent and their brokerage.
Buyer's Agent's Share: The remaining portion goes to the buyer's agent and their brokerage.
The exact split between the listing and buying agents can vary based on agreements between brokerages and individual agent contracts, but the total commission rate is the primary driver of the overall earnings for the real estate professionals involved.
