The Joining Fee Paradox: What Partitioned Pricing Research Says Gyms Are Getting Wrong
Joining fees as a sales lever have been in the industry for as long as I can remember. Frankly, everybody uses them, or rather everybody waives them. January promotion, referral campaign, end-of-quarter push, doesn’t matter. The joining fee is the first thing most operators reach for when they need to look competitive.
I’ve done it. Most operators reading this have done it. The logic is straightforward enough: fewer numbers means less friction means more sign-ups, and the studio down the road just announced they’re doing it so we’d better match.
Some recent research that’s come out in 2026 has me questioning whether that logic actually holds.
Consumers don’t experience price the way a spreadsheet does. They don’t add up components and compare totals in a calm, rational sequence. They evaluate deals, which is a different cognitive process, and the format of a price presentation shapes that evaluation independently of the actual amount being charged. When a gym removes the joining fee and quotes a single monthly rate, it isn’t just making the price smaller. It is changing the psychological structure of what the consumer is being asked to assess.
A 2025 dissertation from Singapore Management University tested four different price formats using 18 months of live Amazon transaction data, holding the actual cost to the consumer constant across all conditions. Price level was removed as a variable entirely. What remained was format, and format alone was enough to shift purchase intent significantly.
TL;DR
Partitioned pricing presents price components separately rather than as one bundled total. Research consistently shows it generates higher purchase intention than all-inclusive pricing, even at an identical total cost. A 2025 SMU dissertation using live Amazon transaction data found partitioned pricing generated the strongest purchase intent of all formats tested. The fitness industry has spent years eliminating the joining fee as a friction point. The psychology suggests that may be solving the wrong problem.
The Amazon Data
In 2025, LI Weiwei’s doctoral dissertation from Singapore Management University analysed monthly transaction data from Amazon.com across 18 months to examine how different price formats affect consumer purchase intent. The distinguishing feature of the study: the out-of-pocket price paid by the consumer was held constant across all formats, with only the presentation changing.
Four formats were tested: direct retail pricing, Prime-exclusive pricing, coupon-based pricing, and partitioned pricing, in which the product price and shipping fee were listed as two separate line items. When price was removed as a variable, format alone drove the difference in purchase intent. Of the four, partitioned pricing generated the strongest result by a meaningful margin.
Abraham and Hamilton’s 2018 meta-analysis in the Journal of Marketing Research adds weight to this finding. Reviewing decades of partitioned pricing literature, they identified consistent evidence that separating a price into components produces more favourable consumer preferences at an identical total. The mechanism is in how the brain accounts for what it sees.
Partitioned Pricing
A pricing presentation in which the total cost is divided into two or more separate components (e.g., product price plus shipping fee, or joining fee plus monthly rate), displayed independently rather than as a single bundled total. The overall price paid may be identical to an all-inclusive price; the difference is purely in how the information is structured.
Transaction Utility Theory (Thaler, 1985)
The theory that consumers evaluate a purchase on two dimensions: acquisition utility (the perceived value of the product relative to its price) and transaction utility (the perceived quality of the deal itself). Transaction utility increases when the format of a price creates a perception of gain, independent of the actual amount paid.
Why the Brain Prefers Two Numbers
Transaction Utility Theory explains the mechanism. Consumers don’t evaluate price as a single, neutral number. They evaluate it as a deal, comparing what they’re paying against an internal reference point for what things should cost. When a price is partitioned, the brain assesses each component in isolation. The base price is judged against the reference price for that item alone. The secondary component is processed as a separate, smaller transaction. Processing two modest wins produces a more favourable overall evaluation than processing one medium-sized neutral.
Abraham and Hamilton’s meta-analysis found the effect is most reliable for standard, expected surcharges. These are costs the consumer already anticipated as part of the transaction. When a surcharge is transparent and its purpose is clear, perceived fairness increases rather than decreases. To the consumer, the second number confirms the primary price is genuinely low. The breakdown reads as transparency, not as a hidden charge.
Morwitz, Greenleaf and Johnson’s foundational 1998 research in the Journal of Marketing Research proposed the attention-anchor mechanism. Consumers tend to anchor on the most prominent number in a price presentation, typically the base price, and underweight the secondary component. The consumer isn’t being deceived by this process. The base price simply does more psychological work than the total, which becomes almost incidental once the base has already registered as reasonable.
The Gym That Solved the Wrong Problem
The fitness industry’s current position on joining fees is close to unanimous. The industry’s answer has been to remove them, bundle them into promotions, or waive them outright. The logic is straightforward: lowering the apparent barrier lowers resistance. Fewer numbers feels cleaner.
That logic works in isolation. Against a backdrop of Transaction Utility Theory, it becomes less obvious.
When a gym waives its joining fee and quotes only the monthly rate, it presents a single number for the consumer to evaluate. That $89/month has to stand alone, measured against whatever internal reference the consumer holds for gym memberships. There is one number to assess, one transaction to weigh, one chance for it to register as a deal worth taking.
When a gym lists the joining fee and monthly rate separately, even at a combined total that matches a competitor’s all-in monthly price, the consumer processes two transactions. The joining fee is evaluated against what they expect onboarding, account setup, and initial access to cost. The monthly fee is evaluated against ongoing membership value. If both feel proportionate, the perception of the overall arrangement improves.
Consolidating everything into a single monthly number didn’t remove the friction of the joining fee. It transferred all of the psychological weight onto the one remaining figure, with nothing left to create a sense of deal value alongside it.
There’s also the question of perceived value signalling. A joining fee, when justified, implies that something is being provided at the point of joining: an initial assessment, a programme setup, a tangible onboarding experience. Waiving it permanently removes whatever that implied. The gym is left with a monthly number and no supporting narrative about why that number represents good value.
What the Research Does Not Say
The research doesn’t support partitioned pricing unconditionally.
Abraham and Hamilton found the effect depends on the nature of the surcharge. Standard, anticipated costs benefit from partitioning. Arbitrary or unexplained charges produce the opposite result. They signal opacity, which reduces perceived fairness and suppresses purchase intent. Whether a joining fee creates suspicion or reads as transparency depends on whether its purpose is visible.
In practice, ‘Joining fee: $99’ is one presentation. ‘Joining fee: $99, which includes your initial fitness assessment, programme design, and access card’ is another. The number is identical and the evaluation is not.
Voester, Ivens and Leischnig’s 2017 review of partitioned pricing literature also noted that consumers respond better when the total is visible alongside the components. Presenting a breakdown without confirming the sum creates uncertainty rather than reassuring the buyer. Showing the total alongside the components combines transparency with the dual-evaluation benefit.
For gym pricing pages, listing ‘Joining fee: $99 / Monthly membership: $79 / Total first month: $178’ may outperform both ‘Join from $79/month’ and a component list with no total stated. The consumer gets the anchor of a low base price, the confirmation of transparency, and a total that validates both.
Research Summary
| Price Format | Mechanism | Consumer Psychology | Implication for Gyms |
|---|---|---|---|
| All-inclusive (bundled) | Single number presented | One transaction evaluated; full price as reference | Simpler, but the monthly rate carries all psychological weight |
| Partitioned (joining fee + monthly) | Components listed separately | Two transactions evaluated; base price anchors attention | Perceived deal value increases if the surcharge is justified and transparent |
| Partitioned with total shown | Components + total listed | Transparency plus dual-win processing | Highest perceived fairness per Abraham and Hamilton meta-analysis |
| Waived joining fee promo | Joining fee removed entirely | Only the monthly rate in frame; value of the waiver lost | Consumer has no reference point from which to perceive a deal |
If the perceived value of a price deal increases when components are visible and justified, what does a permanently waived joining fee communicate about the value of what it was originally supposed to cover?
People Also Ask
What is partitioned pricing in gym memberships?
Partitioned pricing in gym memberships refers to presenting the joining fee and monthly membership rate as separate, clearly stated components rather than quoting a single all-inclusive price. Research in consumer behaviour suggests this approach can increase perceived transaction value when both components are transparent and the rationale for each is evident to the consumer.
Does removing a gym joining fee increase sign-ups?
Not necessarily. Eliminating the joining fee reduces the apparent upfront cost, but research on partitioned pricing (Abraham and Hamilton, 2018; LI, 2025) shows that when the total price paid is held constant, formats that display components separately can generate stronger purchase intent than all-inclusive pricing. A joining fee that clearly communicates what it covers may contribute positively to perceived deal value rather than functioning as a deterrent.
What does Transaction Utility Theory mean for fitness marketing?
Transaction Utility Theory (Thaler, 1985) holds that consumers evaluate purchases on the perceived quality of the deal, not just the value of what they’re receiving. For fitness marketers, price presentation shapes purchase intent as much as price level does. Formats that allow consumers to evaluate each component as a reasonable deal can outperform lower-friction alternatives at an identical total cost.
The joining fee has been framed as an obstacle long enough that most gyms no longer question it. It gets discounted in January, waived for a campaign, or eliminated to look more competitive than the studio down the road. The working assumption is that fewer numbers produce less resistance.
Amazon’s transaction data points the other way. Under the right conditions, fewer numbers leave the brain with less to evaluate in its favour.
