If you have recently started searching for a home or thinking about selling one, you have probably heard the term What Is BAC in Real Estate? You might have wondered what it means and why everyone in the real estate industry seems to be talking about it, especially after 2024.
In this guide, I am going to break down exactly what BAC is, how it works, what changed with the 2024 NAR settlement, and what it means for you as a buyer or seller. Whether you are new to real estate or just need a refresher, this guide will help you understand BAC from every angle.
What Does BAC in Real Estate?
BAC in Real Estate stands for Buyer Agent Compensation. It is the portion of the real estate commission paid to the agent who represents the buyer in a transaction.
In simple terms, when you buy a home, your real estate agent helps you find properties, negotiate offers, and close the deal. BAC is how that agent gets paid. It is either a percentage of the home’s purchase price or a flat fee agreed upon between the buyer and their agent.
Before August 2024, the seller and listing agent would set the BAC and publish it on the Multiple Listing Service (MLS) so buyer agents could see how much they would earn before showing a property. That system has now changed significantly, which we will cover in detail below.
How Does BAC in a Real Estate Transaction?
Understanding the flow of BAC helps you see who pays what and when. Here is a step-by-step breakdown of how BAC works in a typical transaction.
Step 1: The Buyer Signs a Representation Agreement
Buyers must now sign a written agreement with their agent before touring homes. These contracts clarify what services the buyer’s agent will provide and how they will be paid. This agreement spells out the BAC amount, whether it is a percentage or a flat fee.
Step 2: BAC in Real Estate is Negotiated
BAC is completely negotiable and is now agreed upon between a buyer and their agent individually on a case-by-case basis. This can either be a percentage of the purchase price or a flat fee, payable at the close of escrow.
Step 3: The Offer Stage
When a buyer submits an offer on a home, the offer can include a request for the seller to cover the buyer agent’s fee. Buyers may request that the seller cover their agent’s fee, just as they might negotiate for repairs or closing cost credits.
Step 4: Closing
At closing, the agreed BAC is paid out. If the seller agrees to cover it, the funds come from the sale proceeds. If the seller does not cover it, the buyer pays their agent directly.
What Does BAC Stand for in Sales?
In a broader sales context, BAC still refers to Buyer Agent Compensation. Outside of real estate, you might hear BAC used in business-to-business sales environments to refer to compensation structures for sales agents who work on behalf of a buyer or purchasing team. But in residential real estate in the USA, BAC always means the fee paid to the buyer’s agent for representing their client in a property transaction.
What Is a BAC Contract?
A BAC contract is the written agreement between a buyer and their real estate agent that outlines how the buyer’s agent will be compensated. This form outlines services, responsibility, and how the buyer’s agent fee will be handled, whether via BAC from the seller, buyer-paid, or a mix. It also notes what happens if the offer BAC does not fully cover the agreed fee.
This contract is now mandatory in most states before an agent can show a buyer any homes. It protects both parties by making the compensation terms clear before any work begins.
A BAC contract typically includes the agent’s commission rate or flat fee, the duration of the agreement, the services the agent will provide, and what happens if the seller offers less than the agreed BAC.
The NAR Settlement and How It Changed BAC in 2024
This is the most important development in BAC history. In March 2024, the National Association of Realtors settled a landmark antitrust lawsuit for $418 million and agreed to make significant changes to commission policies. Effective August 17, 2024, home sellers are no longer automatically responsible for paying commissions to both their own agent and the buyer’s agent, and a seller’s agent can no longer specify on an MLS how much the buyer’s agent will be paid.
Here is a quick summary of what changed.
| Before August 17, 2024 | After August 17, 2024 |
| BAC was listed on the MLS for all agents to see | BAC cannot be displayed on the MLS |
| Sellers automatically paid buyer agent fees | Sellers choose whether to cover BAC |
| No written buyer agreement required before showings | Written buyer agreement required before touring homes |
| Standard rate was 2.5% to 3% | Rate is fully negotiable per transaction |
| Buyer agents could see commission before showing homes | Buyer agents must contact listing agent to confirm BAC |
What Is the Average BAC Percentage in 2025?
The numbers have shifted since the NAR settlement took effect. According to Redfin, the average buyer’s agent commission increased from 2.36% during Q3 2024 to 2.42% during Q3 2025, showing that commissions have largely rebounded after initially dipping post-settlement.
Commissions are now back to the same level they were at in the first quarter of 2024, when NAR first announced the settlement. Immediately after the settlement was announced, commissions declined, dropping to a low of 2.36% in the third quarter of 2024.
Here is how BAC rates vary by home price range as of 2025.
| Home Price Range | Average Buyer Agent Commission (2025) |
| Below $500,000 | 2.46% |
| $500,000 to $999,999 | 2.32% |
| $1 million and above | 2.22% |
| National average | 2.42% |
Total commission rates across the country range from 4.92% to 6.03% depending on the state, with the national average sitting close to the 2023 rate of 5.49%.
How BAC in Real Estate Affects Buyers
Many buyers assume they do not pay their agent anything. That was mostly true before 2024. Now the picture is more nuanced.
If a seller agrees to cover BAC as part of the offer negotiation, the buyer does not pay out of pocket. But if the seller refuses or offers a lower amount than what the buyer agreed to pay their agent, the buyer covers the difference.
This is why understanding your BAC contract before you start house hunting matters. You need to know your agent’s rate, what happens if the seller does not pay it, and whether you have room in your budget to cover it if needed.
I always tell buyers to ask their agent upfront: what is your fee, and what happens if the seller will not cover it? Get that answer before you sign anything.
How BAC Affects Sellers
Sellers now have more flexibility than ever. You are no longer required to offer BAC. But there is a strategic reason why many sellers still choose to cover it.
BAC fulfills two key purposes: it acts as an incentive for buyer agents to bring their clients to view a seller’s home, and if the seller pays it, the buyer does not have to. In a slow market, offering a competitive BAC can attract more buyer agents and ultimately more offers on your home.
In a buyer-favored market like today’s, buyers can ask for higher commissions for their agents, knowing they may be the only offer on the table. Since the NAR settlement, there has been a lot more discussion about commissions with clients, and more sellers are trying to counter with a lower commission rate.
Common Mistakes Buyers and Sellers Make with BAC
Not reading the buyer representation agreement carefully is the most common mistake buyers make. Many buyers sign without understanding what they owe their agent if the seller does not cover the BAC. Read every line before you sign.
Sellers sometimes assume they save money by offering zero BAC. In a buyer’s market, a low or zero BAC can actually reduce the number of agents willing to show your home and slow down your sale.
Buyers also make the mistake of not negotiating their agent’s fee at all. While BAC has always been negotiable between a buyer and their agent, many buyers accepted the standard 2.5% to 3% rate without discussion. The new rules create a stronger expectation that buyers and agents will negotiate compensation before the agreement is signed.
Pro Tips for Navigating BAC in 2025
Here are practical tips based on how the market works today.
As a buyer, always ask your agent for a full breakdown of their fee and services before signing a representation agreement. Compare two or three agents before committing. Platforms like Clever Real Estate, Redfin, and Zillow let you browse agent profiles and see reviews.
As a seller, talk to your listing agent about current BAC norms in your local market. In most markets, offering 2% to 2.5% to the buyer’s agent still makes strategic sense to attract more showings and offers.
Always put everything in writing. Whether you are a buyer or a seller, the BAC amount, who pays it, and when it gets paid should all be clearly documented in the contract. This protects you from surprises at closing.

Not necessarily. Buyers can still request that sellers cover the BAC as part of their purchase offer, similar to asking for closing cost credits or repairs. Many sellers continue to cover the buyer agent’s fee because it helps attract more offers. However, if the seller refuses or offers less than what the buyer agreed to pay their agent, the buyer is responsible for covering the difference. This is why it is important to understand your BAC contract before you start touring homes.
