Van Westendorp Price Sensitivity Meter (PSM)

An indirect questioning method that asks four questions about price perceptions: at what price is the product a bargain, getting expensive, too expensive, and so cheap you'd question quality. Intersection points define an acceptable price range and an "optimal pricing point." PSM is the most commonly recommended pricing research tool in the consultancy world. PSM tells you what price range respondents can imagine, not what they would actually pay. Peer-reviewed pricing-research findings confirm it yields biased results because of its hypothetical nature and its focus on minimum customer resistance — the most frequently cited validation study (conducted on 36-cent chocolates) found the "optimal pricing point" near an incentive-aligned benchmark only because two opposing biases coincidentally cancelled; the researchers explicitly called for validation on more expensive industrial products that has never materialized. The limits compound in B2B software: the "too cheap, would question quality" question relies on a price-as-quality heuristic that breaks when buyers evaluate via demos, references, and pilots rather than sticker price; the "optimal pricing point" is the mathematical intersection that minimizes total objections, with no functional relationship to revenue maximization, margin protection, or value capture; PSM doesn't model the buying committee, so a single stakeholder's "too expensive" response doesn't reflect what procurement, finance, and the economic buyer will accept under deal pressure; PSM produces a single price range, but B2B contracts are negotiated bundles (multi-product, multi-year, with discounts) where there is no single price to evaluate against the survey; and PSM doesn't model the salesperson's willingness to discount — arguably the largest single force shaping what B2B software customers actually pay, since buyers approach negotiations expecting a discount, procurement teams come prepared with other customers' net prices paid and the discount terms they received, reps trade margin for closeable deals, and the survey-measured ceiling never appears on any signed contract.
