Anchor Pricing Calculator

How the number is derived

Anchor pricing places a higher-priced option beside the one you intend to sell, so the target price is judged against the anchor rather than in isolation. There is no formula for the effect; the calculation is what the range structure does to the mix.

Blended revenue = Σ(price × share), and the question is whether adding an anchor shifts enough share upward to raise the blend. It usually does, and it does so without changing any existing price.

An example

Two options: standard at $58 and premium at $89, splitting 70/30. Blended price is $67.30.

Add a third option at $149. Share shifts to 55% standard, 35% premium, 10% top, because the $89 now reads as the sensible middle rather than the expensive one. Blended price becomes $80.75.

A 20% increase in blended revenue from adding an option that only 10% of customers choose. The anchor did its work mostly by changing how the $89 was perceived, not by selling.

The limitations

The anchor has to be genuine. An option nobody could sensibly buy, priced to make the others look reasonable, is transparent to customers and damages trust in the whole range. The top option needs a real reason to exist and someone who genuinely wants it.

The effect also depends on the options being comparable. Three variants of the same product anchor well; three unrelated products do not, because the customer has no basis for the comparison the anchor depends on.

What this changes

Design the range so the option you most want to sell sits in the middle. Given three comparable options, buyers disproportionately choose the middle one, and that effect is robust enough to build a range around.

Make the top option real: better materials, more of the product, a genuine upgrade, and price it where its value supports. An anchor that is obviously artificial works once and costs more than it earns.

Reference prices and where they come from

Every price is judged against a reference the customer already holds, and if you do not supply one they will find their own, usually a competitor's price or the cheapest thing in the category.

The references available to you are your own range, a stated original price, a comparison against what the alternative costs over time, and the price of the problem the product solves. The last is the strongest and the least used: a $89 product that prevents a $400 repair is being judged against $400 rather than against $58, if the comparison is made.

That is why value-based positioning and anchoring are the same discipline seen from two angles. Both are about controlling which number the customer compares yours against, and the business that leaves that to chance is usually compared against the cheapest option available.

One caution on the stated original price as an anchor: in the UK, EU, Australia and much of the US, advertising a saving against a price the product never genuinely sold at is unlawful, and enforcement has become considerably more active in recent years.

The requirement is usually that the higher price was charged for a meaningful period shortly before. Keeping a dated record of the price history takes seconds at the time and is close to impossible to reconstruct afterwards, which is when it is needed.
