Gabor-Granger Price Test

The classic pricing method: purchase intent at several price points yields a demand curve and the revenue-optimal price.

Gabor-Granger Price Test – questionnaire preview

The Gabor-Granger method is, alongside Van Westendorp, the classic of pricing research – and the right choice when you already have concrete price candidates. Respondents state how likely they would be to buy at a series of price points. This produces a demand curve: what percentage buys at €9.90, how many at €14.90? Multiplied by price, the revenue curve shows where the revenue-optimal price sits – often not where most people would buy. Before fielding, adapt the product description and the five price points to your offer; the price points should fully cover the realistically conceivable range.

When should you use this template?

This template is a great fit for:

  • Before product launches when concrete price candidates exist
  • Before price increases, to estimate volume effects
  • For price differentiation between plans or target groups

From questionnaire to dashboard

From five price questions, the dashboard builds the complete price-demand logic:

  • Demand curve: The share of willing buyers (“definitely” + “probably”) per price point as a falling line – the heart of the Gabor-Granger test.
  • Revenue curve & optimal price: Willingness times price per point: the calculation tile shows which price maximises revenue – your key result for the pricing decision.
  • Purchase intent profile: All five answer levels per price point as 100% stacked bars – shows whether rejection at higher prices is hard (“definitely not”) or soft.
  • Distribution of maximum prices: The open price question as a histogram reveals willingness-to-pay segments sitting between your price points.
  • Segment comparison: Purchase intent crossed with buying frequency or target group – the basis for differentiated pricing.

Frequently asked questions

Gabor-Granger or Van Westendorp – which is right for us?
Van Westendorp (Price Sensitivity Meter) explores which price range is acceptable at all, without preset prices – ideal very early. Gabor-Granger tests concrete price points and delivers demand and revenue curves – ideal once the range is roughly known. Many studies combine both; DataLion has a dedicated Van Westendorp template including the PSM chart.
How do I choose the five price points?
Cover the realistic range completely – from a price that is clearly too low to one that is clearly too high. Even spacing makes interpretation easier. Classically, prices are asked adaptively per person in ascending or descending order; asking all points monadically as in this template is the robust, easy-to-analyse variant.
Don't respondents overstate their willingness to buy?
Yes, systematically – which is why practitioners count only “definitely buy” in full and “probably” partially (e.g. at 50%) in the demand curve. For pricing decisions the shape matters more than the absolute level anyway: where does the curve break?
