Van Westendorp's Price Sensitivity Meter is a pricing survey method that asks each respondent four open-ended price questions — too cheap, bargain, getting expensive, too expensive — and reads an acceptable price range off the points where their cumulative curves cross. It is the standard early-stage price sensitivity analysis for products that do not yet have a market price, and it is routinely used for questions it cannot honestly answer. This guide covers both halves.
The method is the wording. Each question is asked about the same clearly described product, open-ended, in this order:
“At what price would you consider this product to be priced so low that you would question its quality?”
“At what price would you consider this product to be a bargain — a great buy for the money?”
“At what price would you say this product is starting to get expensive — not out of the question, but you would have to think about it?”
“At what price would you consider this product so expensive that you would not consider buying it?”
Wording drift breaks comparability — resist the urge to “improve” these. What you may localize: the product description, the currency, and the purchase frame (per unit, per month).
Each question's answers become a cumulative distribution across price. The two “cheap” curves fall as price rises; the two “expensive” curves rise. Every named price point in the method is just a place where two curves intersect — the price sensitivity analysis is graphical, with no formula beyond counting and plotting.
Building the chart is mechanical: sort every stated price, compute each question's cumulative percentage at each price, invert the two “cheap” distributions so they fall as price rises, and plot all four lines on one axis — in a spreadsheet, that is a sort, four running totals, and a line chart. Suppose 300 screened category buyers price a new subscription tool and the crossings land at PMC $19, IPP $27, OPP $29, PME $44: the finding is a defensible range of $19 to $44 with launch candidates in the high twenties — a starting bid for a real pricing test, not a substitute for one.
The honest reading: treat the acceptable range (PMC to PME) as the finding, and the single-point OPP as a talking point. A crossing of two survey curves is a summary of stated tolerance, not a profit-maximizing price.
Falling curves: “too cheap” (solid) and “bargain” (dashed). Rising curves: “getting expensive” (dashed) and “too expensive” (solid). Where they cross is the whole analysis.
The Optimal Price Point (OPP) is where “too cheap” crosses “too expensive” — the price the fewest respondents reject from either direction. The most quoted number, and the one to treat most carefully: it is a resistance minimum, not a revenue maximum.
The Indifference Price Point (IPP) is where “bargain” crosses “getting expensive” — often read as the price of the perceived market leader, where as many call it cheap as call it pricey.
The Point of Marginal Cheapness (PMC) is the lower bound of the acceptable range — cutting price below it costs more in doubted quality than it wins in value appeal.
The Point of Marginal Expensiveness (PME) is the upper bound — above it, the share calling the price prohibitive climbs faster than any margin gain can justify.
The method dates to 1976, when Dutch economist Peter van Westendorp presented it at the ESOMAR congress — the crossing-point definitions have been industry convention ever since. The main modern refinement is the Newton–Miller–Smith extension, which adds purchase-likelihood questions at each respondent's own bargain and expensive prices, turning stated tolerance into rough demand and revenue curves — worth the extra questions when the pricing decision is close to final.
Van Westendorp answers are only meaningful from people who know the category and its going rates. Screen for recent purchase or active consideration — a general-population sample prices from imagination. The screener craft is its own discipline: survey screening questions.
Open numeric fields, not price menus — menus anchor answers to your options. Fix the currency, state whether tax is included, and name the purchase frame (one-time or per month) or respondents will price different things.
A respondent's four prices must be ordered: too cheap < bargain < getting expensive < too expensive. Answers that violate the order signal confusion or inattention — most practitioners exclude them, and reporting how many you excluded is part of an honest write-up. In a typical fielding, expect to lose roughly 5–15%.
Crossing points are read off cumulative curves, and thin samples make wobbly curves. As a working floor, 150–200 usable respondents per segment you plan to read; comparing segments needs that per cell, not in total.
Where this fits in our platform, stated plainly: the agent programs the four questions with validated numeric fields, the category screener, and quotas, and a pricing survey fields from $99. The crossing chart itself is computed from the CSV export in your spreadsheet or stats tool — we do not draw the Price Sensitivity Meter chart for you today. The fielding discipline (screeners, clean numerics, quotas) is where pricing studies usually go wrong; the chart itself takes roughly twenty minutes for anyone comfortable with spreadsheet formulas, since the export includes one clean column per question.
People answering hypothetical price questions spend imaginary money. The method finds the range where prices feel wrong, not the price that maximizes revenue — validate any launch price with a real test before betting the margin on a survey crossing.
The questions price your product in a vacuum. In a market where a rival sells at $49, your survey's $79 OPP is a psychology reading, not a strategy. The more established the category, the less Van Westendorp should decide.
The intersection points are definitions someone chose in 1976, not results derived from economics. They are useful summaries with fifty years of practice behind them — treat them as structured intuition, and say so in the deck.
The alternatives, honestly matched to jobs: Gabor-Granger when you have candidate prices and want a demand curve — it asks purchase intent at specific price points and supports revenue projection. Conjoint analysis when price trades off against features, brands, or tiers — it forces choices instead of asking opinions. Van Westendorp's durable niche is the step before either: finding the plausible range for something new, cheaply, in one short pricing study.
Four price questions about the same product: at what price would it be so cheap you would question its quality (too cheap); at what price is it a bargain (cheap); at what price is it starting to get expensive but still worth considering (expensive); and at what price is it so expensive you would not buy it (too expensive). All four are asked open-ended, in that order, with the currency and purchase frame fixed.
Van Westendorp has no single formula — the analysis is graphical. Each question's answers become a cumulative distribution across price: the two cheap curves fall as price rises, the two expensive curves rise. Price points are read where curves intersect: the Optimal Price Point (OPP) where too cheap crosses too expensive, the Indifference Price Point (IPP) where bargain crosses getting expensive, and the acceptable range between the Point of Marginal Cheapness (PMC) and the Point of Marginal Expensiveness (PME).
A working floor is 150–200 usable respondents per segment you intend to read, after excluding respondents whose four prices are not in logical order (typically 5–15% fail that monotonicity check). The crossings come from cumulative curves, and small samples make the intersection points jump around — if two segments matter, budget that count for each, not in total.
When the price question is about an established product in a competitive market — stated prices ignore competitors, and the crossing analysis has no grounding in economic theory. Use Gabor-Granger when you have specific candidate prices and want a demand curve (it asks purchase intent at set price points), and conjoint analysis when price trades off against features or brands. Van Westendorp's honest role is early-stage range-finding for something genuinely new, before there is a price to test.
