Van Westendorp Price Sensitivity

Pricing is where a good product wins or loses. Set the price too high and you scare buyers off; set it too low and you sacrifice margin — and, oddly, make people doubt the quality. The hard part is that customers can't tell you their exact price; asked directly, everyone wants it cheaper.

The Van Westendorp Price Sensitivity Meter (PSM), created in 1976, sidesteps that. Instead of asking "what would you pay?", it asks four questions about price perception and reconstructs the whole acceptable range from where the answers cross.

The Four Questions

Every respondent answers the same four questions about the product, each naming a price.

"Too cheap" is the surprise. Below a certain price, customers stop seeing a bargain and start suspecting the product is inferior — a floor that a naive "lower is always better" view completely misses.

Reading the Four Curves

Each question becomes a cumulative curve across the price range, as in the chart above. The intersections of these curves are the outputs that matter.

Running a PSM Study

1. 1Describe the product clearly so everyone prices the same thing.
2. 2Ask the four price-perception questions, letting respondents enter any value.
3. 3Build the cumulative curves for too cheap, cheap, expensive, and too expensive.
4. 4Read off the OPP, IDP, and the PMC Low/High bounds where the curves cross.
5. 5Choose a price inside the acceptable range that fits your strategy.

Strengths and Limits

• Fast and cheap — four questions, no complex design
• Captures the 'too cheap' floor that other methods ignore
• Gives a defensible range, not a single guess
• But it measures price perception, not actual demand — it won't tell you units sold or revenue

PSM in the SKARI Survey Lab

SKARI's Survey Lab runs Van Westendorp end to end: it collects the four price questions, builds the cumulative curves, and computes every key intersection.

• The four price-perception questions built in
• Cumulative curves for too cheap, bargain, expensive, and too expensive
• Optimal Price Point (OPP) and Indifference Price Point (IDP)
• The acceptable range (PMC Low to PMC High) marked on the chart

Frequently Asked Questions

Why ask about "too cheap"?

Because price signals quality. Below a floor, buyers assume the product is inferior — so the lowest price isn't the best price.

Does PSM give me the profit-maximizing price?

No — it gives an acceptable range and a balance point. For revenue optimization, use Gabor-Granger or conjoint alongside it.

How many respondents do I need?

Enough for smooth curves — typically a few hundred. Thin samples make the intersections jumpy and unstable.

Key Takeaways

Van Westendorp turns an impossible question — "what should we charge?" — into four easy ones, and returns a price range grounded in how customers actually perceive value, including the floor below which cheap reads as inferior.
