That is when the most costly question arises: &#8220;how much should we charge for it?&#8221; An answer based on a rough estimate is an expensive gamble, while <strong>Van Westendorp pricing research<\/strong> and the Gabor-Granger technique make it possible to replace guesswork with data from actual target audiences before sales begin.<\/p>\n<h2>When is it worth measuring the acceptable price level rather than guessing it?<\/h2>\n<p>Price is the only element of an offering that directly generates revenue &#8211; all the others generate costs. Yet it is often set with less rigor than any other product parameter. Teams may spend weeks refining features, packaging, and communication, only to set the price in a matter of minutes based on margin, competitor prices, or intuition. This is when <strong>Van Westendorp pricing research<\/strong> becomes a real alternative to intuition.<\/p>\n<p>The need to measure price arises in several typical situations. It is worth considering research when at least one of the following circumstances applies:<\/p>\n<ul>\n<li>you are launching a new product or service and have no historical sales data to rely on,<\/li>\n<li>you are entering a new market or segment where customers&#8217; price references differ from those you have encountered so far,<\/li>\n<li>you are planning to reposition a product and want to determine how a price change will affect its perceived value,<\/li>\n<li>your offering is innovative and has no direct equivalent against which customers can compare it,<\/li>\n<li>you are seeing a decline in conversion and suspect that the price barrier lies elsewhere than you assumed.<\/li>\n<\/ul>\n<p>In each of these cases, the problem is not the lack of a price, but the lack of knowledge about how the target audience responds to different price levels. Price threshold research moves this response from the sales stage, where an error means lost revenue, to the design stage, where adjustments are usually less costly than after launch. Van Westendorp pricing research answers a different question than cost analysis &#8211; it does not indicate how much a product needs to cost to be profitable, but rather the range within which target audiences consider the price credible.<\/p>\n<h2>How do Van Westendorp and Gabor-Granger work in research practice?<\/h2>\n<p>Both methods belong to the family of survey techniques, but they measure different things and work best in different contexts. It is worth understanding how their mechanisms differ before selecting one for a project.<\/p>\n<p><strong>Van Westendorp Price Sensitivity Meter<\/strong> is based on four open-ended price questions asked after respondents have reviewed a product description. Respondents state the price at which a product is: too expensive to consider; too cheap to inspire confidence in its quality; expensive but still worth considering; and a bargain. The distribution of these four responses is used to construct cumulative curves, whose intersections determine threshold points. Two are key: the lower credibility threshold, below which the price raises concerns about poor quality, and the upper threshold, above which the product falls outside the acceptable range for a significant proportion of the target audience. The space between them is the acceptable price range, while additional intersections indicate the price indifference point and the so-called optimal price point, or the point of lowest price resistance.<\/p>\n<p>The Van Westendorp method answers the question of an <strong>acceptable product price<\/strong> &#8211; the range within which the price makes sense to the target audience at all. However, it does not indicate how many people would declare that they would purchase the product at a given price. That is the role of <strong>Gabor-Granger<\/strong>.<\/p>\n<p>The <strong>Gabor-Granger<\/strong> technique involves presenting respondents with specific price levels and asking about their willingness to purchase at each one. Prices should be presented in random order to reduce anchoring effects. This is used to build a stated demand curve showing the proportion of respondents who declare a purchase at successive price levels. Comparing this curve with price makes it possible to estimate the level at which stated revenue is highest. Gabor-Granger therefore assumes that you already know the general price range you are working within &#8211; which is why it is often used after Van Westendorp, which defines that range.<\/p>\n<p>In a typical project, the sequence is as follows:<\/p>\n<ol>\n<li>prepare the product description and price stimulus so that all respondents evaluate the same value proposition,<\/li>\n<li>use the <strong>price sensitivity meter<\/strong> to determine the acceptable price range,<\/li>\n<li>narrow the range down to several price points and test them using the Gabor-Granger technique,<\/li>\n<li>analyze the demand curve and identify the level that maximizes stated revenue within the accepted range,<\/li>\n<li>interpret the results in the context of segments, if the sample allows for subgroup analysis.<\/li>\n<\/ol>\n<p>As Hume&#8217;s Institute experts point out, a price set &#8220;by eye&#8221; is the most expensive decision in a project &#8211; customers will verify it anyway, only with their wallets rather than in a survey. The difference is that survey-based verification is reversible and inexpensive, while verification with wallets means lost transactions that no one will ever count. In Hume&#8217;s Institute projects, the range defined by respondents is often noticeably wider or narrower than the range the product team had previously considered &#8220;obvious.&#8221;<\/p>\n<h2>How do the limitations of the two methods differ, and where is it easy to make mistakes?<\/h2>\n<p>Van Westendorp pricing research and Gabor-Granger are stated preference techniques &#8211; they measure what respondents say, not what they would do at the checkout counter. This is their greatest limitation and the source of most interpretation errors. Purchase declarations are always more optimistic than actual behavior, which is why Gabor-Granger results should not be read as a sales forecast, but as a map of price sensitivity.<\/p>\n<p>The most common pitfalls concern research design rather than the analysis itself. It is worth paying attention to several of them:<\/p>\n<ul>\n<li><strong>A weak stimulus description<\/strong> &#8211; if respondents do not understand exactly what they are pricing, their answers describe an imagined product rather than yours. The description must be unambiguous and identical for the entire sample.<\/li>\n<li><strong>An unrepresentative sample<\/strong> &#8211; prices established using people outside the target group describe the acceptance of someone who would not buy the product anyway. The sample should reflect the profile of the actual target audience.<\/li>\n<li><strong>Anchoring effects in Gabor-Granger<\/strong> &#8211; presenting prices in ascending or descending order distorts responses. The order should be randomized or controlled in the research design.<\/li>\n<li><strong>Overinterpreting the optimal point in Van Westendorp<\/strong> &#8211; curve intersections are indicative guidelines, not precise values to enter into a price list.<\/li>\n<li><strong>Omitting segmentation<\/strong> &#8211; an average range for the entire sample may mask the fact that different target groups have different acceptance thresholds.<\/li>\n<\/ul>\n<p>It is also worth understanding how Van Westendorp differs from approaches that better simulate purchase choices. Choice-based methods, such as choice-based conjoint (CBC), place respondents in situations where they must make trade-offs between price and other product attributes, often providing a closer approximation of the purchase decision. However, they are more expensive and more complex to implement. Van Westendorp pricing research remains fast and cost-effective, and its strength lies in defining a range at an early stage before more advanced analytics are deployed. Gabor-Granger falls somewhere in between &#8211; it provides a stated demand curve, but still relies on declarations.<\/p>\n<h2>How should you choose a method for your own price threshold research?<\/h2>\n<p>The choice between techniques depends on the stage the product has reached and which question matters most at a given time. The following criteria help match the method to the situation:<\/p>\n<ul>\n<li>if you have no price reference point at all and want to define a range to start from &#8211; use the <strong>price sensitivity meter<\/strong>,<\/li>\n<li>if you already know the approximate range and want to see how demand responds to specific levels &#8211; use Gabor-Granger,<\/li>\n<li>if you want to estimate the point that maximizes stated revenue &#8211; you need a demand curve from Gabor-Granger,<\/li>\n<li>if price is only one of many purchase decision parameters and you want to understand its importance relative to other attributes &#8211; consider a choice-based method instead of either pricing technique,<\/li>\n<li>if you have a limited budget and timeline but need a quick indication of an acceptable product price &#8211; Van Westendorp is the most cost-effective starting point.<\/li>\n<\/ul>\n<p>In many projects, the two techniques complement each other: Van Westendorp defines the boundaries within which it is worth searching, while Gabor-Granger indicates where within those boundaries the point with the best relationship between stated demand and price lies. This combination provides an acceptance range and an indication of demand response without the need to deploy the most complex methods immediately.<\/p>\n<h2>Frequently asked questions<\/h2>\n<h3>What is the Van Westendorp method?<\/h3>\n<p>The Van Westendorp Price Sensitivity Meter is based on four price questions: too expensive, too cheap, expensive but acceptable, and a bargain. The responses are used to construct cumulative curves, whose intersections define the acceptable price range and threshold points. The method measures perceived value and price credibility, rather than the number of people willing to purchase.<\/p>\n<h3>How does Van Westendorp differ from Gabor-Granger?<\/h3>\n<p>Van Westendorp defines the acceptable price range based on open-ended questions and does not forecast demand. Gabor-Granger presents specific price levels and measures stated willingness to purchase, building a stated demand curve. In practice, Van Westendorp is used to define the range, while Gabor-Granger is used to test specific points within it.<\/p>\n<h3>When does price research provide a reliable acceptance range?<\/h3>\n<p>A reliable result requires a representative sample of target audiences and an unambiguous product description that is identical for all respondents. Prices in Gabor-Granger should be presented in random or controlled order to reduce anchoring. Results should be treated as a map of price sensitivity, not as an exact sales forecast.<\/p>\n<p><strong>Ask about research into the acceptable price level for your product.<\/strong> Hume&#8217;s Institute will help select the right technique &#8211; Van Westendorp, Gabor-Granger, or a combination of both &#8211; and design the research to define a data-based price range rather than one based on intuition. <a href=\"https:\/\/humes.pl\/en\/contact\/\">Contact Hume&#8217;s Institute<\/a> to discuss the project scope and timeline.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The pricing decision is usually made when the product is already finished and the team has no time for market experiments.
