Psychological pricing: presenting and testing prices fairly

Price affects decisions, and its presentation matters too. A price ending in 9, a discount or a bundle does not have the same effect for every product and audience. Before changing prices, check what customers understand, what they actually pay and what your margin allows.

1. Choose a useful hypothesis

A round price can make a service easier to read; a lower-ending price can suggest an economical offer. These are hypotheses to test, not conversion rules. Positioning, amount, alternatives and the relationship with the seller change the context.

Ask a specific question: do customers understand differences between two packages? Does the price cover the expected service? Does presentation make the total easier to compare? More clicks are insufficient if orders become less profitable.

2. Show what the amount includes

Describe scope, duration, quantities and options. For subscriptions, distinguish monthly payment from total cost and commitment. For bundles, explain components and limits. Avoid a “from” price without useful information about what customers can actually buy.

In Switzerland, the Price Indication Ordinance governs consumer offers in particular. Requirements depend on the offer and context. Consult SECO price indication guidance to determine applicable retail and unit price, supplement and shipping requirements. A bespoke B2B quote differs from consumer merchandise.

3. Check reference prices

A crossed-out price or discount announcement needs verifiable justification. Do not create a high price just to make a discount attractive. Self-comparison rules have changed: check the permitted method, reference-price duration and records to retain in the SECO FAQs.

When selling across markets, check reference-price conditions and permitted duration separately for each jurisdiction. Transparency depends on more than how a number is typeset.

4. Compare offers without hiding choices

Present packages in the same units and over comparable periods. Explain concrete differences, exclusions and exit terms. A highlighted offer should remain understandable without making alternatives hard to read.

Avoid preselected paid options, late-disclosed charges and unsupported scarcity counters. A clear interface allows customers to review their choice before ordering and find the terms.

5. Measure sales and margin

Compare variants over a defined period and population. Keep offers, terms and charges explicit. Measure orders, contribution margin, cancellations and customer service questions. A small difference in a small sample does not establish a lasting effect.

Fictional example: a business tests two presentations of an unchanged subscription, one focusing on monthly payment and the other annual commitment. Both amounts and terms appear in each version. The test examines understanding, orders and complaints; it promises no sales uplift.

Prepare 2027 prices

Check costs, scope and rules before publishing new prices. Retain evidence for discount announcements and assign an owner to corrections. Reuse valid presentations rather than change prices for a supposed trend.
