Brand-Price Trade-Off
Also known as: BPTO, Brand/Price Trade-Off, Brand-Price Trade-Off Analysis, Sequential Brand-Price Choice
Brand-Price Trade-Off (BPTO) is a pricing-research technique that measures how consumers trade off brand preference against price by presenting competing brands at varying prices and asking, repeatedly, which one they would buy. In the classic procedure the respondent chooses a brand from a set shown at given prices, and then the chosen brand's price is raised in the next round, forcing successive choices until the respondent switches to a cheaper alternative or to none. The sequence of switch points reveals how much of a price premium each brand can command before customers defect, mapping brand loyalty and cross-brand switching. Developed by British market researchers in the 1970s and conceptually rooted in the price-perception work of Gabor and Granger, BPTO is in effect a constrained, sequential choice experiment focused on brand and price. Modern practice analyzes the resulting choices with a logit model under random utility theory, yielding brand utilities, price elasticities, and a simulator for share under different competitive price scenarios. It remains popular for fast-moving consumer goods where brand-versus-price is the dominant decision.
Key highlights
- Directly measures the price premium each brand can command and the most likely switching destinations.
- The shelf-like, sequential task is realistic and intuitive for branded fast-moving consumer goods.
- Efficiently probes the price region where switching occurs rather than wasting questions on obvious choices.
- Yields own- and cross-price elasticities and a share simulator when analyzed with a logit choice model.

When to use it
Use Brand-Price Trade-Off when the purchase decision in a category is dominated by the tension between brand preference and price, typically fast-moving consumer goods, and you want to quantify how much premium each brand can charge before customers switch and where they switch to. It is well suited to estimating own- and cross-brand price elasticities and simulating competitive pricing scenarios in a realistic, shelf-like task. BPTO is less appropriate when products differ on many attributes beyond brand and price, where full choice-based conjoint better captures the trade-offs, and its sequential escalation can teach respondents the mechanism, encouraging gaming, so designs must guard against this. Because choices are stated, results should be validated against scanner or sales data where available.
Strengths & limitations
- Directly measures the price premium each brand can command and the most likely switching destinations.
- The shelf-like, sequential task is realistic and intuitive for branded fast-moving consumer goods.
- Efficiently probes the price region where switching occurs rather than wasting questions on obvious choices.
- Yields own- and cross-price elasticities and a share simulator when analyzed with a logit choice model.
- Focuses on brand and price alone, ignoring other attributes that may drive choice in richer categories.
- Sequential price escalation can reveal the mechanism, prompting respondents to game the task and hold out for higher prices.
- Stated choices may overstate switching and price sensitivity relative to real shelf behavior.
- Classic switch-point analysis is ad hoc; sound inference requires a properly specified choice model and design safeguards.

Frequently asked
How does BPTO differ from choice-based conjoint?
BPTO is a specialized, sequential choice task that deliberately restricts the trade-off to brand versus price and escalates the chosen brand's price round by round to find switch points. Choice-based conjoint shows fixed sets of profiles described by many attributes and asks for a single choice per task, without sequential escalation. BPTO's narrow focus and shelf-like realism make it efficient for branded categories where brand and price dominate, but choice-based conjoint is more flexible and statistically cleaner when several attributes matter, and its randomized designs avoid the gaming risk that BPTO's predictable price increases can introduce. Both are analyzed with logit choice models under random utility theory.
What is a switch point and what does it tell us?
A switch point is the price of a respondent's currently chosen brand at which they abandon it for a competitor or stop buying. Because the respondent switches when the net value of the old brand falls to that of the alternative, the price gap at that moment expresses the premium the brand commanded, its monetary brand equity relative to that competitor. Aggregating switch points across respondents reveals each brand's pricing power and the most common switching destinations. However, raw switch points are noisy and design-dependent, so best practice uses them descriptively and relies on a fitted choice model for elasticities and share predictions.
Why can sequential price escalation bias the results?
Because BPTO raises the price of whatever brand the respondent just chose, the pattern is predictable: keep picking your favorite and its price keeps climbing. Some respondents learn this and game the task, either holding out to see how high it goes or switching strategically rather than according to true preference, which can distort estimated switch points and elasticities. Practitioners mitigate this by randomizing or disguising the escalation, limiting the number of rounds, mixing in non-escalating tasks, and analyzing the data with a choice model that does not depend on any single switch point. Validation against real scanner or sales data is the strongest safeguard.
