I used to think negotiation was about persuasion. About having the right words, the right tone, the right strategy. Turns out I was missing the whole point.

There’s a concept from negotiation theory called BATNA — Best Alternative to a Negotiated Agreement. It sounds academic, but it’s actually the single most practical thing you can know before walking into any discussion where two people want different things.

Your BATNA is what you’d actually do if the talks fall apart. Not what you hope for. Not what sounds good in your head. What you’d realistically do tomorrow morning when nothing has been agreed.

I learned this properly during a salary negotiation a few years back. I’d spent weeks preparing talking points, rehearsing responses, building a case for why I deserved more. I walked in confident, armed with market data and a list of achievements.

The other side pushed back hard on every point. And I panicked. Not because their arguments were good, but because I had no answer to the one question that actually mattered: what if they just say no?

I took the offer. It was below what I wanted, and I knew it. But I’d convinced myself there was no alternative. There was — I just hadn’t bothered to look for one.

That negotiation cost me money, sure. But the real loss was the lesson I should have learned earlier: knowing your BATNA changes everything.

How to figure out yours

The process is straightforward, even if the thinking isn’t always comfortable.

List every option you actually have. If this deal falls through, what do you do? Not the dream scenario — the real one. Another job? A different role in the same company? Staying where you are and waiting things out? Freelancing? Taking a pay cut somewhere else? Be honest about what you’d actually do, not what you wish you could do.

Work out what each option is actually worth. Money matters, but so does time, stress, growth potential, location, the people you’d be working with. A job that pays ten percent less but has better hours and no weekend work might be the better deal. Don’t reduce everything to a single number — that’s a trap. But do give each option a proper assessment.

Pick the best one. That’s your BATNA. It might not be glamorous. It might involve staying in a job you’re unhappy with for another six months while you look elsewhere. That’s fine. It’s still your fallback, and it’s still valuable.

What to do with this knowledge

Once you know your BATNA, three things change.

You stop accepting bad deals. If the offer on the table is worse than what you’d do anyway, walking away isn’t failure — it’s the rational choice. Most people stay in bad negotiations because they’re afraid of having no deal. But a bad deal is worse than no deal.

You stop being manipulated. People who know they have alternatives are harder to pressure. You can spot when someone is trying to create false urgency or make you feel lucky to be in the room. Your BATNA is your anchor — it keeps you from being pulled into decisions based on fear rather than value.

You understand the other side better. Try to figure out what their BATNA is. Are they desperate to close? Do they have plenty of alternatives? This tells you more about their position than anything they’ll explicitly say. A seller with no other buyers behaves very differently from one with three offers on the table.

The uncomfortable parts

Here’s what nobody tells you about BATNA: knowing it doesn’t make negotiations easy. It makes them honest.

You might discover your alternative is terrible — staying in a dead-end job, having no income for months, starting over somewhere unfamiliar. That’s not weakness. It’s information. And it’s better to know before you’re in the room than after.

You might also realise your current deal is actually good. If your BATNA is worse than what you already have, that’s worth something too. It changes how you approach things — not just in negotiations, but in how you think about the relationships and commitments you’re already in.

And yes, most people don’t bother doing this. They walk into salary discussions, business deals, even personal conversations without any idea of what they’d do if things don’t go their way. No wonder so many agreements feel wrong afterwards — the person on the other side knew something you didn’t.

One thing to remember

Your BATNA isn’t fixed. It changes as circumstances change, as new information comes in, as you take action to improve your alternatives. The person who negotiates from a position of strength isn’t the one with the most power — it’s the one who’s done the work to know what they’d do if things fall apart.

I wish I’d understood this before that salary negotiation. Not because it would have gotten me a better number, but because it would have stopped me from feeling trapped in a room where I’d already lost.
