What Is a Reservation Price?
Reservation price is the binding threshold at which a party becomes indifferent between completing and walking away from a transaction. For buyers, it is the maximum they will pay; for sellers, the minimum they will accept. Unlike willingness to pay, which can be aspirational, reservation price is a firm binary cutoff.
Worked example
A manufacturer evaluating an analytics platform has a BATNA (renewing its legacy system) valued at $180,000 annually. After factoring in $12,000 in switching costs, its buyer reservation price is $168,000. Any quote above that triggers a walkaway; any quote below is economically rational.
How Is Reservation Price Calculated?
Four inputs determine reservation price:
- BATNA value: the monetary value of the next-best alternative if no deal is reached.
- Opportunity cost: value foregone by committing to this deal instead of another.
- Switching and transaction costs: one-time costs that reduce the net value of a new agreement.
- Risk adjustment: a discount (for buyers) or premium (for sellers) that accounts for uncertainty in the alternative.
These inputs produce two formulas:
Buyer RP = BATNA Value − Switching Costs − Risk Discount
Seller RP = Cost to Produce/Deliver + Minimum Acceptable Margin + Risk Premium
Reservation price is not static. It recalculates whenever any input changes: a new competitive bid, a tighter deadline, or a revised cost estimate can all shift the threshold.
Reservation Price vs. Willingness to Pay
Willingness to pay informs how to price; reservation price determines whether to transact at all. Pricing decisions that optimize for average willingness to pay can still produce deals that fall below a seller's reservation price and generate a loss.
Buyer and Seller Reservation Prices in B2B Negotiation
Both parties in a negotiation hold a private reservation price. When the buyer's maximum exceeds the seller's minimum, the overlap defines the Zone of Possible Agreement (ZOPA). When no overlap exists, no rational deal is possible.
Three factors are especially relevant in enterprise contexts:
Confidentiality. Revealing your reservation price collapses your negotiating range, allowing the counterparty to anchor directly to your limit rather than explore mutual value.
Dynamic revision. Reservation prices shift under time pressure, new competitive bids, or changing business priorities, making continuous reassessment important throughout a negotiation.
Multi-variable structure. In B2B deals, reservation price is rarely a single dollar figure. It is a bundle covering price, payment terms, service levels, and risk allocation.
Price management workflows, such as those in Vistaar's platform, help sellers encode defensible floor prices that reflect real cost structures, reducing the risk of approving deals below the acceptable threshold.
Reservation Price vs. Reserve Price
These terms share etymology and underlying logic but operate in different contexts.
A reserve price is a seller-set minimum bid used in formal auction settings. A reservation price is a private walkaway threshold held by either party in any transaction. The context, disclosure norms, and application differ.
