The Ackerman Method, Made Practical

What is the Ackerman method in negotiation and how do you use it to make offers?

The Ackerman method, popularized by Chris Voss in Never Split the Difference, is a structured offer-and-counteroffer system. You set a target price, then make a sequence of calculated bids that converge on that target with decreasing increments — signaling that you are near your limit even as you create the appearance of flexibility. The method uses psychology to make your counterpart feel they have won a hard bargain.

Most negotiators concede in equal steps — which signals that more is available. The Ackerman method, drawn from FBI hostage negotiation and commercial deal-making, uses decreasing concession size and deliberate non-round numbers to signal genuine limits. The counterpart feels they have extracted maximum concessions — even when you have stayed close to your target. These practices break down how and why the method works.

Practices

Set your target before you open — never anchor to their first offer

Know your target and your walkaway before any numbers are exchanged, so their anchor doesn’t colonize your frame.

Use the Ackerman bid sequence: 65%–85%–95%–100% of target

Make four calculated offers that converge on your target with shrinking steps — each concession signals you are approaching your limit.

Use precise, non-round numbers in final offers

A specific non-round number signals calculation and research, not an arbitrary position.

Accompany your final offer with a small non-monetary concession

Adding a low-cost non-monetary item to your final offer signals genuine limit while giving the counterpart a win.

Maintain empathy and calibrated questions throughout the Ackerman process

The bidding system only works inside a relationship — empathy and understanding keep the counterpart engaged rather than walking away.

Rehearse the full Ackerman sequence before high-stakes negotiations

Walk through every bid and response scenario in advance so you execute under pressure with prepared clarity.
