Anchoring, ZOPA, and the Art of Not Killing the Deal

One of the biggest misconceptions about negotiation is that it’s all about finding common ground.

It’s not.

In Prof. Amit Nandkeolyar's class we learned how negotiation is about shaping the ground on which the conversation happens. And nothing shapes that ground more powerfully than the first offer.

Great negotiators do three things well:

1. They anchor smartly

2. They expand the 'pie' before slicing it

3. They always know their walk-away point

The Hidden Power of the First Offer

The first number on the table has an outsized psychological impact. It becomes the reference point, even when both sides know it’s just a starting point.

This is called anchoring.

Once an anchor is set:

• Every counteroffer reacts to it

• Every concession feels larger or smaller because of it

• The final deal gravitates toward it

Even experienced negotiators subconsciously adjust around the anchor rather than starting fresh.

That’s why the first offer often decides who captures most of the value, not who argues better.

Creating Value vs Capturing Value

Here’s a mistake many smart people make (I’ve made it too):

“If we collaborate and create value, the outcome will naturally be fair.”

Unfortunately, that’s not how negotiations work.

There are two distinct phases:

1. Value creation: expanding what’s on the table

2. Value capture: deciding who gets how much

You can be excellent at creating value and still walk away with less than you deserve if you fail at the second part.

ZOPA: The Space Where Deals Actually Happen

ZOPA stands for Zone of Possible Agreement.

In simple terms:

It’s the range where both sides can say yes without being worse off.

Here's an example:

• Seller won’t go below ₹10k

• Buyer won’t go above ₹15k

The ZOPA is ₹10k to ₹15k. If your negotiation stays within this zone, a deal is possible.

If you anchor high:

• The zone feels shifted upward

• Concessions happen around your number

• You capture more value without changing the actual limits

Expanding the ZOPA: Why More Issues = Better Deals

Here’s a powerful insight most people miss:

The more things you negotiate on, the easier it is to reach agreement.

Why?

Because not all issues are equally important to both sides. Money might matter more to you.

Timing, flexibility, or risk might matter more to them.

By adding more issues, you:

• Create trade-offs

• Reduce deadlocks

• Increase perceived fairness

Examples of expandable variables:

• Payment terms

• Timelines

• Scope

• Risk-sharing

• Future opportunities

• Volume commitments

• Exclusivity

Instead of fighting over one number, you’re now trading across dimensions. This expands the ZOPA and makes agreement far more likely.

BATNA: Your Real Source of Power

BATNA stands for Best Alternative To a Negotiated Agreement.

In layman terms:

“What will I do if this deal doesn’t happen?”

Your BATNA determines:

• How confident you negotiate

• How much pressure you feel

• Whether you can walk away

The stronger your BATNA:

• The less desperate you sound

• The less you concede

• The more credible your position becomes

People often think negotiation power comes from persuasion. In reality, it comes from options. If walking away is genuinely okay for you, the other side can usually feel it.

Don’t Win the Deal and Lose the Relationship

Here’s the subtle part most negotiation advice ignores.

You can:

• Anchor too aggressively

• Extract maximum value

• Technically “win” the deal

And still lose. Why?

Because negotiations are rarely one-shot games.

People remember:

• Whether they felt respected

• Whether the process felt fair

• Whether they’d want to work with you again

Over-optimising for your side can leave a sour taste, kill trust, and shut doors that might have been far more valuable later.

The best negotiators don’t just maximize outcomes, they optimize relationships and outcomes together.

The Mental Model I Now Use

Before making a first offer, I ask myself:

1. Is this anchor strong but defensible?

2. Does it leave room for movement?

3. Am I expanding the deal, not just pushing my number?

4. Do I have a clear BATNA if this fails?

5. Will the other side still want to work with me after this?

If the answer is yes, I proceed. If not, re-evaluate.

So, create value. Capture your fair share. But never forget, how you negotiate often matters more than what you negotiate.
