The Van Westendorp Price Sensitivity Meter asks buyers four price questions instead of the useless one. Too cheap to trust, a bargain, getting expensive, and too expensive to consider. The midpoint of the two extremes is your Optimal Price Point, and the gap between the middle two is the range you can move in without losing the room.
Optimal Price Point = (too cheap + too expensive) ÷ 2 · Acceptable range = midpoints of the crossing pairs
Takes the four Van Westendorp price-perception responses (too cheap, cheap, expensive, too expensive) and derives an Optimal Price Point, Indifference Price Point, and an acceptable price band. Run it before you publish a price, and only after you've surveyed 30+ people in your actual ICP. Under that sample, the curves don't stabilize and the output will look authoritative but lie to you.
Your numbers
Price below which buyers doubt the product is real.
Price that feels like a steal but still credible.
Price that needs justification but is still reasonable.
Price above which buyers walk away regardless of value.
The verdict
Indifference: $54.00
The band is more than twice as wide as its floor, which means the price has room in it. You are probably charging less than the top half of your buyers expected to pay.
What the number means
| Acceptable price band | Reading | What to do about it |
|---|---|---|
| Prices entered out of order | Act now | The four answers have to rise in order: too cheap, bargain, getting expensive, too expensive. Out of order, the method has nothing to measure and neither do you. |
| Acceptable band under 100% wide | Healthy | Your buyers broadly agree on what this is worth, which is the whole point of asking. Anchor at the optimal point and stop deliberating. |
| Acceptable band 100% to 200% wide | Fragile | The band is more than twice as wide as its floor, which means the price has room in it. You are probably charging less than the top half of your buyers expected to pay. |
| Acceptable band over 200% wide | Fragile | This much disagreement usually means two different buyers are wearing one label. Split them and run the four questions again on each, before the pricing page has to serve both. |
Worked examples
| Situation | Numbers in | Answer out | Verdict |
|---|---|---|---|
| Solo-founder tool | $29 · $49 · $99 · $199 | $114 optimal | Tight band from $64 to $124. Anchor at $114 and move on. |
| Prosumer product priced timidly | $10 · $29 · $99 · $199 | $105 optimal | Wide band. There is room above the current price and nobody is using it. |
| Two audiences answering as one | $5 · $19 · $299 · $999 | $502 optimal | The spread is the finding. This is two markets in a trench coat. |
| Enterprise pilot | $8,000 · $12,000 · $20,000 · $30,000 | $19K optimal | Tight band. Anchor high and let procurement do its ceremonial haggling. |
How this is calculated
This is the Van Westendorp Price Sensitivity Meter. A 1976 method that survives because it works. Each buyer answers four price questions; the calc converts the median answers into two key prices:
- Optimal Price Point (OPP) = (too_cheap + too_expensive) / 2. The price with the lowest combined "no" rate.
- Indifference Price Point (IPP) = (cheap + expensive) / 2. The price at which the buyer pool is roughly split.
- Acceptable band = [too_cheap, too_expensive]. Wider band = more buyer confusion about value.
For a true multi-respondent survey, the OPP is the intersection of cumulative "too cheap" and "too expensive" curves. This calc uses the median-cohort shortcut so a single 4-input dataset works.
Source: Peter van Westendorp, "NSS Price Sensitivity Meter" (1976). Still the most cited pricing-research method in academic marketing literature.
What this doesn't tell you
- Whether buyers will actually pay. Stated price isn't the same as willingness to pay. Buyers under-estimate what they'll spend on category buys and over-estimate on novelty buys. Pair with a small Fake Door Test before launch.
- Which buyer segment to target. A wide band usually means you're surveying mixed segments. Re-run the calc separately for each persona and pick the segment with the tightest band as your launch buyer.
- How to package. The calc gives one price; most products ship 2-3 tiers. Use the OPP as the anchor tier and price the higher tier 2-3× above to make the anchor look like the bargain.
What is the Van Westendorp price sensitivity meter?
A four-question survey developed by the Dutch economist Peter van Westendorp in 1976, still in use because nothing simpler has beaten it. Rather than asking what would you pay, which invites a polite lie, it asks at what price the product becomes too cheap to trust, a bargain, expensive, and out of the question. Plotting the answers reveals the range buyers already consider reasonable, without anyone having to predict their own behaviour.
How many people do I need to survey for pricing?
Ten to twenty buyers from a single segment is enough to see the shape, and a hundred is enough to be confident about it. Purists will tell you two hundred and fifty, which is correct for a consumer launch and irrelevant if you have not yet found ten people who will take your call. Numbers from a dozen real buyers beat perfect methodology applied to nobody.
Why not just ask people what they would pay?
Because the answer is worthless in a specific, well-documented way. Asked directly, buyers anchor low to appear sensible, or high to appear generous, and either way they are describing an imaginary purchase with imaginary money. The four-question format works because it never asks anyone to predict their own behaviour. It asks where the boundaries of credibility sit, which people are surprisingly good at describing.

Pricing Validation
Most founders pick a price by looking at competitors and shaving 20%. That's not pricing strategy, it's matching. Real pricing validation produces a price you can defend against your own ego and your buyer's pushback.
How do I find my target market?
Narrow in four passes. (1) Start with the broad category your idea sits in. (2) Filter by buyer behavior: who currently has this problem and is doing something about it? (3) Filter by reach: who can you actually contact via the channels you have today? (4) Filter by willingness to pay: who has budget authority and a price point that clears your unit economics? The output is a specific buyer profile you could name 10 people who match. If you can't, you haven't narrowed enough.

TAM / SAM / SOM
Three market-size numbers, from biggest to smallest. TAM is the ceiling if everyone bought. SAM is who you could realistically reach. SOM is what you could actually win in the next one to three years. The last one is the one that matters.
