Van Westendorp Price Sensitivity Meter
Van Westendorp Price Sensitivity Meter Framework · Also known as: Price Sensitivity Meter, PSM, Van Westendorp Method
The Van Westendorp Price Sensitivity Meter is a market research method developed by Peter van Westendorp in 1993 for assessing consumer price perception and estimating willingness-to-pay ranges without directly asking customers their maximum price. The method uses four simple questions about price acceptability, yielding estimates of optimal price, acceptable price range, and price perception zones.

When to use it
Apply the van Westendorp Price Sensitivity Meter when estimating optimal price for new products, evaluating whether to raise or lower prices on existing products, assessing price perception of a competitor's offering, understanding price elasticity across customer segments, or testing multiple price points before launch. It is particularly valuable for consumer products where customer preferences are diverse and price perception varies. Works well as a quick, cost-effective first pass at price research; pair with conjoint analysis or WTP studies for deeper analysis.
Strengths & limitations
- Simple four-question format is easy to administer online, by phone, or in person, reducing survey fatigue
- Provides a clear, actionable price range rather than a single point estimate, showing the zone of price acceptability
- Infers willingness-to-pay indirectly, avoiding the biases of directly asking customers their maximum price
- Enables rapid segmentation: compare price sensitivity across customer groups, identifying opportunities for differential pricing
- Results are highly sensitive to the price ranges presented in the survey; anchoring effects mean that showing very high prices shifts responses upward
- Stated price acceptability does not always predict actual purchasing behavior; customers may be willing to accept higher prices in surveys but resist them at point of purchase
- The method provides less granular data than conjoint analysis or choice experiments, which reveal how price interacts with other features
- Interpretation of the Indifference Price Point and Optimal Price Point is somewhat subjective; where exactly curves intersect depends on visual interpretation
Frequently asked
What price ranges should we use for the survey?
Determine a range that is realistic for the product and market. For a new product, use competitor pricing, production costs, and target customer research to inform bounds. Typically, span 3-4x the lowest plausible price: if you expect optimal price to be $20, test from $5 to $40. Narrow ranges lose information; very wide ranges create confusion and anchoring artifacts. Pilot test with a small sample to validate the range is appropriate.
Should we show the same price range to all respondents?
In standard PSM, yes—use the same range for all respondents to ensure comparability. However, if you are testing across very different market segments (e.g., students vs. luxury consumers), consider segment-specific ranges in separate surveys to avoid anchoring effects that bias lower-income respondents upward when shown high prices.
How many respondents do we need?
Minimum 100-200 for an initial analysis; 300-500 for more robust results and subgroup analysis. Larger samples are better for detecting statistically meaningful differences across customer segments.
Can we use PSM for B2B products and services?
Yes, but with caution. B2B pricing often involves contract negotiation, volume discounts, and long-term relationships, making stated price acceptability less predictive of actual deals. PSM works better as an initial screening tool; validate results with actual negotiation data or pricing pilots. For high-value B2B solutions, pricing depends heavily on perceived business value; include value-related questions alongside PSM to ground price perception.
