How to Calculate Cost Per Use: The Full Method

A $1,695 Peloton Bike used three times a week for three years costs roughly $6 to $7 per ride once residual value and subscription are folded in. A $69-a-month gym membership used twice a week over the same period costs closer to $8 per visit. The gap between those two numbers — and the fact that most buyers never calculate either — is the entire reason cost per use exists as a discipline.

Sticker price answers one question: can you afford the thing today. Cost per use answers a more useful one: what does each unit of value actually cost you over the life of the purchase. For a $150k+ household, where the binding constraint is rarely the upfront cash and almost always whether the money is well-deployed, the second question is the one worth modeling. This article lays out the full method — every input, every adjustment, and the arithmetic that connects them — using current figures verified against primary sources.

The formula, stated precisely

Cost per use has one canonical form. Take the purchase price, subtract what the item is worth when you are done with it, add every recurring cost you paid along the way, and divide by the number of times you used it:

cost per use = (purchase price − residual value + cumulative recurring costs) ÷ total uses

Each term hides a decision, and the decisions are where most amateur calculations fall apart. Purchase price should include tax, delivery, and assembly — the all-in cash that left your account, not the headline number on the product page. Residual value is what you could sell the item for at the end of your holding period, not what you paid and not what you wish it were worth. Recurring costs are every mandatory ongoing payment: subscriptions, maintenance, consumables, insurance. Total uses is the count over the same horizon you used for residual value. Mismatch the horizons and the whole figure is meaningless.

For subscriptions with no resale value — a gym membership, a streaming service, a class pass — the formula collapses to something simpler, because residual value is zero and there is no asset to sell:

cost per session = (monthly fee × months) ÷ sessions attended

That distinction matters more than it looks. A durable good with strong resale can post a low cost per use even at a high sticker price, because you recover capital at the end. A subscription recovers nothing. This is the structural reason a well-chosen piece of equipment sometimes beats the recurring alternative — a dynamic worked through in detail in the Peloton versus gym membership analysis.

Key figures at a glance

The worked example below builds on five verified inputs. Each is sourced to a primary or named industry source with its data period.

Sources: Peloton published pricing and support documentation, October 2025; eBay active and completed listings for used Peloton Bikes, 2025; Health & Fitness Association 2024 U.S. Health & Fitness Consumer Report; Bureau of Labor Statistics American Time Use Survey, 2024 results.

Working the example, term by term

Start with the asset. A new Peloton Bike lists at $1,695 as of Peloton’s October 2025 repricing, the first hardware-and-subscription increase the company had pushed through in years. Add the All-Access Membership at $49.99 per month, also reset in October 2025. Hold the bike for three years and ride it three times a week, and you have 156 weeks at three sessions — roughly 468 rides, assuming you do not skip a single one. That last assumption is doing heavy lifting, and the methodology section returns to it.

Now the residual value, which is where most home-calculated estimates quietly inflate. Peloton’s own Repowered program lists certified refurbished Bikes around $1,145, but that figure includes the company’s margin, inspection, and warranty — it is a retail price, not what a private seller nets. Peer-to-peer listings on eBay for used Original Bikes cluster well below that, commonly in the $500 to $850 band depending on generation and condition. Use the midpoint of that private-market range, roughly $675, as a working residual. Anyone modeling their own purchase should pull live completed listings rather than trust a single point estimate; secondary-market depreciation on connected fitness equipment has been steep since the pandemic surge unwound.

Assemble the terms. Net hardware cost is $1,695 minus $675, or $1,020. Subscription over 36 months at $49.99 is $1,799.64. Total outlay net of resale: $2,819.64. Divide by 468 rides and the cost per use lands at about $6.02 per session. The total cost of ownership — the full $2,819.64 before dividing — is the figure that belongs in a budget; the per-use number is what belongs in the decision. Confusing the two is common enough that it deserves its own treatment, which the cost per use versus total cost of ownership breakdown handles directly.

Calculation by Finluxy using verified inputs above. Purchase price and subscription: Peloton, October 2025. Residual value midpoint derived from eBay used-Bike listings, 2025. Usage frequency is a stated assumption, not a measured average; see methodology.

Run the gym comparison through the subscription formula to see the contrast. At $69 a month — the 2024 average reported by the Health & Fitness Association — three years of dues totals $2,484. A member who attends twice a week logs roughly 312 visits, for a cost per session near $7.96. Bump attendance to three times a week and the gym falls to about $5.31 per visit, undercutting the bike. The variable that decides the winner is not price. It is frequency.

The Finluxy Use-Value Score

A raw cost per use tells you what something costs but not whether that cost is good for its category. A $6 ride is excellent for boutique cycling and mediocre for a folding stationary bike. The Finluxy Use-Value Score normalizes against the category median so the comparison is apples to apples. It is a 0–100 index: 100 × (1 − actual cost per use ÷ category median cost per use), capped at 100 and floored at 0. Fifty means you are at the category median, anything above means you are beating it.

Using a home-fitness category median of $8.40 per session, the Peloton example at $6.02 scores 100 × (1 − 6.02 ÷ 8.40), or about 28. The twice-weekly gym member at $7.96 scores roughly 5 — barely better than median, because low frequency erodes the advantage of the lower monthly fee. The three-times-weekly gym member at $5.31 scores about 37, the best of the three. The score rewards exactly what cost per use is built to surface: high utilization of a reasonably priced asset.

Methodology

Pricing inputs were verified against primary and named industry sources rather than recalled. Peloton hardware and subscription figures come from the company’s October 2025 published pricing and support documentation. Gym dues reflect the Health & Fitness Association’s 2024 U.S. Health & Fitness Consumer Report, which put the U.S. average at $69 per month. Exercise frequency context draws on the Bureau of Labor Statistics American Time Use Survey 2024 results, which measured average daily participation in sports, exercise, and recreation at 21.5 minutes across the population age 15 and over. Residual value was synthesized from eBay used-Bike listings observed in 2025 and expressed as a range because secondary-market prices vary materially by generation, condition, and region; I used the midpoint of the private-resale band rather than Peloton’s refurbished retail price, which carries the company’s margin.

Where a single point figure could not be defended — residual value most notably — the analysis states a range and uses its midpoint, flagging that readers should pull live data before committing. Usage frequency is the one input no external source can supply for an individual; the 3×/week figure is an explicit assumption, not a measured average, and the model is built so that swapping in your own honest frequency changes the output transparently. The BLS figure of 21.5 minutes per day is a useful reality check here: it implies the average American exercises far less than three structured sessions a week, which is precisely why the frequency assumption is the variable most likely to flatter a purchase on paper and disappoint in practice.

What the data shows that most coverage misses

Most cost-per-use write-ups treat residual value as the swing factor — the clever adjustment that separates a real analysis from a naive one. The numbers say otherwise. Move the Peloton residual from $500 to $850, a 70% swing across the entire plausible range, and cost per use shifts from about $6.40 to $5.66 — a difference of 74 cents per ride. Now hold residual constant and move frequency from three sessions a week to two: cost per use jumps from $6.02 to roughly $8.78, a swing of $2.76. Frequency is nearly four times as powerful as the residual-value adjustment everyone fixates on.

This is the overlooked structural fact of the entire framework. The denominator dominates the numerator. People spend their analytical energy hunting for a better resale estimate or a maintenance figure to the dollar, while the input that actually determines the answer — how often they will really use the thing — is the one they fudge most optimistically. The honest version of this method starts by interrogating the usage assumption, not the price. A purchase that looks efficient at aspirational frequency and turns wasteful at realistic frequency is the most common trap in the category, examined further in the purchases that look efficient but aren’t analysis.

What this means for a $150k+ household

At this income level the upfront $1,695 is not the decision. The decision is opportunity cost and behavioral honesty. A household that buys the bike, rides it eleven times, and lets it become a clothes rack has not spent $1,695 — it has spent roughly $154 per ride plus the floor space, which is a worse outcome than almost any membership. The same household that genuinely rides three times a week has made one of the more efficient fitness purchases available. The asset is identical; the only difference is the denominator, and the denominator is a function of habit, not money.

The practical move is to run the method twice: once at the frequency you intend, and once at the frequency you have demonstrated in the past for similar commitments. If the two numbers diverge sharply, trust the second. For higher-ticket durables with strong resale — the logic extends well beyond fitness, into Herman Miller chair cost per day, premium headphones cost per hour, and luxury mattress cost per night — the residual recovery can make a premium item the rational choice on a per-use basis even when the sticker stings. The broader discipline of applying this lens before any major purchase is laid out in the smarter purchase evaluation method, and the same arithmetic that justifies a premium sometimes justifies the opposite conclusion — that a cheaper item used constantly beats a luxury one used rarely. The framework does not have a bias toward spending more or less. It has a bias toward using what you buy.
