**The price range your customers will accept.**

Ask your customers four questions about one product or service, enter or paste their answers, and see the lowest and highest prices they accept, the optimal price between them, and what each one leaves you after it costs you to deliver.

No email needed. It runs Van Westendorp’s Price Sensitivity Meter in your browser: nothing you enter leaves this page unless you ask for the result by email.

The Price Range Finder, walked through. Forty example answers about a cooler temperature logger: the four questions, the curves and the range they give, and what each price leaves after the cost to build one. Video walkthrough (MP4, narrated): https://mnpsystems.ca/video/tools/price-range.mp4

## The four questions

Each customer answers four questions about one specific product or service, in this order:

1. **Too cheap.** At what price would it be so cheap that you would doubt its quality?
2. **A bargain.** At what price would it be a bargain, a great buy for the money?
3. **Getting expensive.** At what price would it start to seem expensive, though you would still consider it?
4. **Too expensive.** At what price would it be so expensive that you would not consider it?

The tool reads one customer a line, their four prices in that order, pasted from a spreadsheet or a survey export (tabs, commas or semicolons). A row whose prices do not rise from the first to the fourth is left out. It needs at least 5 answers, and says the range will still move under 30.

## The four prices

- **Lowest acceptable** (point of marginal cheapness): where the share who call a price too cheap meets the share who would not call it a bargain.
- **Optimal** (optimal price point): where "too cheap" meets "too expensive", so the fewest customers rule the price out.
- **Indifferent** (indifference price point): where "a bargain" meets "getting expensive".
- **Highest acceptable** (point of marginal expensiveness): where "too expensive" meets the share who would not yet call it expensive.

The curves are drawn as steps, one per question, with the acceptable range between the lowest and highest prices shaded.

## After cost

Given what one unit costs to deliver, the tool shows what each of the four prices keeps, and calls the margin thin when the optimal price keeps under 30% of itself. Where the range is tight, the next step it offers is the Design-to-cost review for a product (Engineering) or the AI opportunity audit for a service (AI): fixed jobs, quoted before work starts.

## A worked example

A Wi-Fi temperature logger for walk-in coolers, priced by 40 restaurant owners (made up for the example), costing $42 to build: the range runs from $43 to $70, the optimal price is $50 and the indifferent price $56. At the optimal price you keep $8 on each sale, 16% of the price. That is thin: a small rise in cost, or a discount, takes it.

## What is kept

Nothing. The answers are read in the browser. Only a visitor who asks for the result by email sends them, and the result is scored again from them to write that email.
