Best Alternative To a Negotiated Agreement

What is BATNA?

BATNA is an acronym that stands for Best Alternative To a Negotiated Agreement. It is defined as the most advantageous alternative that a negotiating party can take if negotiations fail and an agreement cannot be made. In other words, a party’s BATNA is what a party’s alternative is if negotiations are unsuccessful. The term BATNA was originally used by Roger Fisher and William Ury in their 1981 book entitled “Getting to Yes: Negotiating Without Giving In.”


BATNA - BEst Alternative to a Negotiated Agreement


Importance of BATNA

BATNA is often used in negotiation tactics and should always be considered before a negotiation takes place. It is never wise to enter into a serious negotiation without knowing your BATNA. The value of knowing your best alternative to a negotiated agreement is that:

  1. It provides an alternative if negotiations fall through.
  2. It provides negotiating power.
  3. It determines your reservation point (the worst price you are willing to accept).


Illustration of BATNA

The following diagram illustrates each party’s best alternative to a negotiated agreement (seller and buyer):


BATNA - Illustration



  • ZOPA stands for “Zone Of Potential Agreement.” It is the overlap between the seller’s and buyer’s settlement range.
  • Seller’s settlement range is a biddable range acceptable to the seller.
  • Buyer’s settlement range is a biddable range acceptable to the buyer.
  • Buyer’s/Seller’s worst case is the reservation point of the respective parties.



  • Buyer offers a price that is lower than the seller’s worst case, then the seller is better off going with an alternative.
  • Seller offers a price that is higher than the buyer’s worst case, then the buyer is better off going with an alternative.


Example of BATNA

Colin needs a car and is negotiating with Tom to purchase his car. Tom offers to sell his car to Colin for $10,000. Colin scours through Craigslist and finds a similar car to which he assigns a dollar value of $7,500. Colin’s BATNA is $7,500 – if Tom does not offer a price lower than $7,500, Colin will consider his best alternative to a negotiated agreement. Colin is willing to pay up to $7,500 for the car but would ideally want to pay $5,000 only. The relevant information is illustrated below:


BATNA - Example 1


In the diagram above, if Tom demands a price higher than $7,500, Colin will take his business elsewhere. In the example, we are not provided with Tom’s BATNA. If we assume that Tom can sell his car to someone else for $8,000, then $8,000 is Tom’s BATNA. In such a scenario, an agreement will not be made, as Tom is only willing to sell for a minimum of $8,000, while Colin is only willing to purchase at a maximum of $7,500.

If Tom’s best alternative to the deal is selling the car to a dealership, which would offer him $6,000, then both parties can come to an agreement because Tom’s reservation point would be $6,000. In the situation described, the diagram would look as follows:


BATNA - Example 2


In this case, there is a zone of potential agreement – $6,000 to $7,500. Somewhere within this range, the two parties should be able to come to an agreement.


Identifying Your BATNA

As illustrated in the example above, having a best alternative to a negotiated agreement before entering into negotiations is important. Had Colin not had a BATNA, Tom would have had more bargaining power. Knowing Colin’s BATNA is at $7,500, the highest price that Tom would be able to sell his car to Colin for is $7,500.


Here is a process developed by Harvard Law School to develop the best alternative to a negotiated agreement:

  1. List all alternatives to the current negotiation – what could you do if negotiations fall through?
  2. Evaluate the value of each alternative – how much is each alternative worth to me?
  3. Select the alternative that would provide the highest value to you (this is your best alternative to a negotiated agreement).
  4. After determining your BATNA, calculate the lowest-valued deal that you’re willing to accept.
