Every negotiation involves uncertainty. Your counterpart might agree to your terms, push back, or walk away entirely. The difference between negotiators who thrive under pressure and those who don’t often comes down to one factor: knowing exactly what you'll do if the deal falls through.
That's where BATNA—your Best Alternative to a Negotiated Agreement—comes in.
“Sometimes you may have very good options," says Harvard Business School Professor Michael Wheeler in the online course Negotiation Mastery. "Other times, your alternatives may not be very attractive. Whatever the case, pick what you'll do if there’s no deal.”
Your BATNA is that decision. It’s your backup plan, baseline, and primary source of leverage. To help you identify your strongest alternative and define your walk-away point, here’s a guide to understanding BATNA and determining your own.

What Is BATNA?
Your Best Alternative to a Negotiated Agreement (BATNA) is the course of action you pursue if a deal falls through. Rather than an escape plan, it’s a strategic anchor.
Wheeler illustrates this concept in Negotiation Mastery with a familiar scenario: shopping for a new car. If one dealership’s price feels too high, you don’t simply accept it—you explore alternatives. You might visit another dealership, consider leasing, or repair your current car. The strongest of those options becomes your BATNA.
“Even as the negotiation heads toward a conclusion, the choice isn’t necessarily between deal and no deal,” Wheeler explains in Negotiation Mastery. “There may be a third option, which is to keep negotiating in hopes of getting a better deal.”
BATNA isn’t just a number; it’s a strategy. You might accept a slightly higher price if the dealership offers better services, or sell your car to a friend for less than a dealer would pay. The specifics may shift, but defining your BATNA keeps your decisions rational and shapes how you negotiate over time.
Why a Strong BATNA Determines Leverage
Leverage in negotiation comes from understanding your alternatives well enough that pressure doesn’t cloud your judgment.
An example from Negotiation Mastery that highlights this involves Brims, a fast-growing UK coffee chain, and Easterly, a local bed-and-breakfast owner. After Brims purchased land in Bridport, England, to open a new location, Easterly challenged the company’s building permit, citing a decades-old deed restriction that prohibited commercial use of the property.
At first glance, Brims seemed to hold the upper hand. With an estimated 80 percent chance of winning, litigation seemed like the strongest option.
As Wheeler notes in Negotiation Mastery, “Brims’ BATNA is fairly straightforward. Either they reach an agreement with Easterly, or they may face a protracted legal battle about their right to use the land.”
But leverage isn’t determined by odds alone. Litigation would be costly, time-consuming, and potentially damaging to Brims’ reputation.
“Even if they win, a long battle with Easterly might create a hostile environment for them with customers,” Wheeler says in Negotiation Mastery.
Ultimately, Brims’ strongest BATNA wasn’t winning in court. It was selling the property to a residential buyer and securing an alternative site. While less dramatic than litigation, this option aligned better with the company’s long-term goal: continued expansion.
The lesson is clear: leverage isn’t just about the probability of winning. It’s about the overall quality of your alternative, and the confidence that comes from knowing you have one.
How to Identify Your BATNA
1. List All Possible Alternatives
If leverage depends on your alternatives, the first step is identifying them.
Map out every realistic path forward if the deal doesn’t happen. The goal isn’t optimism, it’s clarity. Separate what you hope will work from what will actually serve your strategic goals.
In the Brims example, that meant fully examining three options:
Fight against Easterly
Hold the property and wait
Sell the land and purchase another site
Although litigation initially seemed attractive, a thorough BATNA analysis requires evaluating each option across multiple dimensions: price, timing, reputational risk, and opportunity cost.
“The range of walk-aways that people in the Brims role set is striking—some high, some much lower,” Wheeler says in Negotiation Mastery. “The wide range also reflects honest differences in perception.”
Even with identical information, individuals reached different conclusions.
Risk tolerance also plays a key role. For some, an 80 percent chance of success feels secure. For others, a one-in-five chance of losing is too significant to ignore.
Listing every viable alternative replaces instinct with analysis and clarifies what you'll actually do if negotiations fail.
2. Evaluate Which Alternative Is Most Effective
After identifying your options, evaluate them rigorously. A strong BATNA isn’t the option that satisfies everyone on your team; it’s the one that delivers the best expected outcome after accounting for costs, probabilities, and strategic objectives.
Wheeler summarizes Brims’ BATNA in Negotiation Mastery: “Their best alternative is to sell the property to a residential buyer for £125,000 gross, before brokers’ fees come into the equation.”
One essential rule: ignore sunk costs when performing a BATNA analysis. “The BATNA analysis for Brims shouldn't be affected by the £165,000 they’ve had to pay for an alternative site. That has nothing to do with their BATNA,” Wheeler stresses in Negotiation Mastery.
What’s already spent is gone—what matters is the expected result going forward.
If you pursue alternate routes, break each into detailed steps and compare them to your original deal. That keeps decision-making disciplined and ensures any additional investment is intentional.
3. Convert Your BATNA Into a Walk-Away Threshold
A BATNA only provides leverage if it shapes your behavior at the negotiation table. That means translating it into a specific walk-away point—the limit on price, scope, or terms at which you would choose your alternative over the deal in front of you.
Your BATNA is your Plan B. Your walk-away threshold is the trigger that tells you when to use it.
This connects directly to the Zone of Possible Agreement (ZOPA), the range in a negotiation in which parties can find common ground. The walkaway threshold defines one boundary of the ZOPA, while your counterpart’s threshold defines the other. Where they overlap, a viable deal exists.
In Negotiation Mastery, Wheeler describes a mock negotiation between an employee, Caitlin, and her manager, George, over a bonus and promotion. Rather than walking in and simply listing reasons she deserved both, Caitlin anticipated his objections and prepared responses in advance.
Had she entered the conversation without a clear sense of her alternative, or without thinking through how she would handle resistance, she could have left empty-handed.
“First, Caitlin prepared well,” Wheeler explains in Negotiation Mastery. “Instead of merely listing all the reasons why she should get the promotion, she also anticipated the reasons, legitimate and tactical, that George might have had for turning her down.”
She proposed a three-month trial period, reframed concerns, and secured a follow-up meeting to define performance metrics. Rather than leaving the outcome to chance, Caitlin created structure and momentum, effectively operationalizing her walk-away threshold.
Converting your BATNA into a defined limit protects you from rejecting reasonable offers out of pride and accepting weak ones out of fear.
4. Reassess Before—and During—Negotiation
Your BATNA isn’t static. It evolves as new information emerges and circumstances change.
“BATNA then isn't just something that gets set at the beginning of a negotiation; it can change during negotiation,” Wheeler notes in Negotiation Mastery.
Market conditions shift, organizational priorities evolve, and what seemed like a strong alternative last week may look weaker—or stronger—today.
Time can reshape leverage. As Wheeler says in Negotiation Mastery, “Perhaps your counterpart will be under increasing pressure as time wears on, or you may believe the situation will improve for you so that your walk-away becomes better, giving you more leverage.”
As negotiation tools advance, artificial intelligence can help identify blind spots. “AI can help identify negotiation ‘bugs’—like failing to ask good questions or offering below your BATNA,” Wheeler explains in Negotiation Mastery. While technology won't augment the relational judgment that great negotiators develop over time, it can surface gaps in logic and behaviors that are easy to miss in the moment.
Effective negotiators don’t calculate their BATNA once and move on. They refine, test, and adjust it throughout the negotiation process.

Pressure-Test Your BATNA Before You Enter a Negotiation
Strong negotiations begin before you enter the room; they begin with your BATNA.
When you take the time to define your BATNA, stress-test your alternatives, and translate your best path into a clear walk-away threshold, you shift from reacting to negotiating with intention. Ambiguity becomes strategy. Uncertainty becomes leverage.
Your most powerful deal starts with knowing exactly what you’ll do without one.
