    Introduction

    A gym, a car wash and an oil change shop have little in common on the surface. Underneath, they share a business model. Each sells a repeated service from many similar sites, each depends on a local catchment of customers who come back again and again, and each can be copied site by site once the format works. That makes them more like restaurants than like retailers: the unit of analysis is the site, its returns decide how fast the chain can grow, and the best operators turn occasional visits into recurring revenue through memberships.

    The scale of the leading chains shows how far the model can go. Planet Fitness ended 2025 with about 20.8 million members across 2,896 clubs and system-wide sales of $5.3 billion, with same-club sales up 6.7%, according to its full-year results. Mister Car Wash ended the same year with 548 locations and about 2.3 million members of its Unlimited Wash Club, who generated 79% of its wash sales in the fourth quarter. This article explains what makes these businesses attractive, how memberships work and how fitness, car wash and automotive service economics differ.

    What Makes Multi-Unit Services Attractive

    Consumer services sit between restaurants and retail. Like restaurants, they sell an experience made on site, so they cannot be replaced by online shopping. Like retail, they depend on location, traffic and the density of the store network. Their appeal to investors comes from a combination of traits:

    • Repeat visits: customers need the service regularly, whether weekly washes, monthly workouts or oil changes every few months
    • Recurring revenue: memberships convert those visits into predictable monthly payments
    • Fragmented markets: most local markets are served by independent operators, leaving room for consolidation
    • Replicable formats: a proven site design can be rolled out across many markets
    • Resistance to e-commerce: the service must be delivered in person

    The sector's links to sponsors are deep. Many chains are owned or were built by private equity, which values recurring revenue and the ability to grow by opening and buying sites. How those roll-ups are built is covered in consumer services roll-ups: de novo vs acquisition.

    Personal and home services

    The same model extends to many smaller categories. Hair salons, massage and waxing studios, childcare centers, tutoring, pet grooming and veterinary clinics run from local sites; home services such as pest control, lawn care, plumbing and heating and cooling send technicians to customers' homes from local branches. These businesses are usually more labor-intensive than gyms or car washes, since every service is delivered by a trained person, so their growth depends on recruiting and keeping staff. Many are franchised, and many are the targets of sponsor roll-ups that buy independent operators and put them on shared systems for scheduling, marketing and purchasing.

    Membership Models: Churn and Lifetime Value

    Memberships are what separate the best consumer services businesses from ordinary retailers. A member pays a monthly fee for access, usually by automatic payment, which makes revenue predictable and visits more frequent, and gives the operator a subscription-like revenue base.

    Churn Rate

    The percentage of members who cancel in a given period, usually measured monthly. Churn determines how long the average member stays and therefore how much each member is worth over their lifetime; even small differences in monthly churn change lifetime value substantially.

    The value of a member depends on three numbers: the monthly fee, the margin earned on it and how long the member stays. Average tenure is roughly one divided by the monthly churn rate.

    Cohorts and the first months

    Churn is not even across a member's life. New members cancel most often in their first few months, when the habit has not formed, while members who stay past their first year tend to stay much longer. Operators therefore track cohorts, groups of members who joined in the same month, and watch how many remain after three, six and twelve months. A business with improving early retention is building a stronger base even if its total member count grows slowly, while one that fills its funnel with promotions but loses those members quickly is spending to stand still.

    The site as the acquisition channel

    The value of a member must be set against the cost of winning one, the same logic used for online brands in DTC and Amazon: how brands sell direct and online. In physical services, much of the acquisition cost is the site itself: a well-located club or car wash on a busy road attracts members with less advertising than a poorly located one, and the sign out front does much of the marketing. That is why site selection is the most important decision in the sector, and why operators that pick sites well can grow profitably with modest marketing budgets.

    Pricing and grandfathering

    Raising membership prices is the most powerful pricing lever and the riskiest. Operators often apply increases to new members first while grandfathering existing members at their old rate, which protects retention but delays the benefit. Planet Fitness described 2025 as the first full year of a 50% price increase for new members of its basic Classic Card membership, showing how a long-held low price point can be lifted gradually without driving away the existing base.

    The membership mix

    The share of revenue from members, rather than single visits, is a measure of revenue quality. At Mister Car Wash, Unlimited Wash Club members generated 79% of fourth-quarter wash sales, up from 75% a year earlier, according to the company's full-year results. A higher membership mix makes revenue steadier, less exposed to weather and easier to forecast, which is why operators push members hard at the point of sale.

    Fitness Clubs: High-Volume, Premium and Boutique

    Fitness is the largest membership-based consumer service, and it splits into three models with very different unit economics.

    High-Volume, Low-Price (HVLP)

    A fitness club model built on very low monthly dues, large numbers of members and simple, equipment-focused clubs with few staff and limited amenities. HVLP clubs rely on many members who visit infrequently, which keeps capacity costs low relative to revenue.

    The high-volume, low-price model

    HVLP clubs keep dues low and membership counts high, betting that many members will visit only occasionally. Clubs are large, open floors of cardio and strength equipment, with few classes, limited staff and low operating costs, and a low price that attracts first-time gym users. The model's strength in a downturn is that a low monthly fee is one of the last expenses members cut, and members trading down from pricier clubs can add to its base. Planet Fitness, the largest HVLP brand, combines franchising with company-owned clubs and equipment sales to franchisees: in 2025 its franchise segment earned $468.0 million of revenue, its corporate-owned clubs $546.1 million and its equipment segment $310.1 million, with total revenue of about $1.3 billion and adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) of $551.6 million. Franchisees must re-equip their clubs on a schedule, which turns equipment into a recurring revenue stream for the franchisor, a variation on the fee model covered in the franchise model: royalties, franchisees and refranchising.

    Club economics and utilization

    A gym's capacity is set by its floor space and equipment, but demand is concentrated in a few peak hours before and after work, which makes capacity management central to club economics. Clubs plan membership levels around that peak: an HVLP club can sell far more memberships than it could serve at once because only a fraction of members visit on any day. The key ratios are members per club, visits per member and the share of members who attend regularly. A club with too few members cannot cover its rent and equipment; one with too many at peak hours frustrates members and raises churn, so operators manage capacity through club size, pricing tiers and opening hours.

    Premium clubs

    Premium clubs charge far higher dues for large facilities with pools, studios, childcare, spas and cafes. They earn more per member and keep members longer, but they cost much more to build and run and often own or lease large, purpose-built properties. Their economics resemble a hospitality business as much as a gym, with significant income from personal training, classes, food and other in-club spending, and their value depends on attracting affluent members who treat the club as part of their routine. Owning large properties also gives premium operators sale-leaseback options to fund growth.

    Boutique studios

    Boutique studios focus on a single activity, such as cycling, rowing, Pilates or strength training, in small spaces with instructor-led classes. They are cheap to open and easy to franchise, which allowed rapid growth, but they face high churn as members move between trends and studios. Their revenue depends on class utilization and instructor quality, and a popular instructor leaving can hurt a studio's numbers. Boutique franchisors trade on how quickly their concepts grow and how well their franchisees do, and a brand whose franchisees struggle can see openings stall quickly.

    Car Washes: Express Tunnels and Memberships

    The car wash industry has been transformed by the express tunnel format: a conveyor carries the car through an automated tunnel in a few minutes while the driver stays inside, with free vacuums afterward. Tunnels need few staff and process many cars an hour, but they are expensive to build, so their economics depend on high volume and a strong membership base.

    Memberships fit car washes especially well. A member paying a monthly fee for unlimited washes visits more often, and revenue becomes far less dependent on weather, which otherwise drives day-to-day sales sharply.

    Tunnel economics

    A tunnel's returns come from membership density in its catchment and from keeping site operating costs low through automation.

    Operators lift those returns by selling the real estate and leasing it back, which recovers much of the investment and raises the return on remaining equity, and by moving members up to higher-priced plans with extra services. Mister Car Wash, one of the largest US operators, had net revenue of about $1.05 billion in 2025, comparable store sales growth of 2.9% and adjusted EBITDA of $345.4 million, and opened 29 new greenfield locations during the year.

    Sponsors, build-outs and take-privates

    Express car washes became one of private equity's favorite consumer sectors, with sponsors funding rapid new-site construction and acquisitions of independent washes. That wave brought two risks: oversupply in markets where several chains built new tunnels close together, and heavy leverage on businesses that depend on discretionary spending. Ownership has moved between public and private markets too. Leonard Green & Partners, already a shareholder, took Mister Car Wash private at $7.00 per share in cash, an enterprise value of about $3.1 billion, completing the deal in May 2026, according to Morris Nichols, counsel to the company's special committee.

    Car wash real estate is also a source of capital. Many operators own their sites and sell them to net-lease investors in sale-leasebacks to fund growth, a structure covered in the Real Estate guide's sale-leaseback advisory.

    Automotive Aftermarket Services: Collision and Oil Change

    The automotive aftermarket covers the services cars need after they are sold, from routine maintenance to accident repair, and its non-discretionary demand makes it one of the steadiest parts of consumer services. Its demand grows with the number of vehicles on the road and their age, since older cars need more care, and it is largely non-discretionary: a car that needs an oil change, new tires or repairs after an accident will get them.

    Quick lube and routine maintenance

    Quick lube chains specialize in fast oil changes and simple maintenance, often in a format where the driver stays in the car while technicians work from a service bay below. The model wins on speed and convenience: a visit can take minutes without an appointment, which suits busy drivers and builds repeat business. Growth comes from new stores, more services per visit and premium products such as synthetic oils that lift the average ticket. The long-term question is electrification: electric vehicles need no oil changes, so operators are adding services such as tire rotation, battery checks and fluid exchanges to reduce their dependence on oil.

    Tires, glass and general repair

    Between quick lube and collision sit chains that sell tires, replace windshields and perform general mechanical repairs. Tire and service chains combine a retail product with installation labor, so their results move with replacement cycles and average ticket, while glass repair, like collision, depends on insurer relationships. General repair is the most fragmented segment, dominated by independent shops, and the most technician-dependent. Multi-brand automotive platforms have bought across these categories, using shared marketing, purchasing and fleet relationships to grow faster than any single format could.

    Collision repair

    Collision repair is a different business. Most repairs are paid by insurers, which steer customers to approved repair shops through direct repair programs, negotiating labor rates and setting standards for speed and quality. Large collision consolidators have bought thousands of independent body shops to win insurer relationships through scale and consistent service. The consolidation logic is the same as in other roll-ups: buy independent shops at modest multiples, bring them onto shared systems and insurer programs, and sell the larger platform at a higher multiple, though collision's dependence on skilled labor makes integration harder than in more automated formats. The business is labor-intensive and constrained by a shortage of skilled technicians, and modern vehicles with sensors and driver-assistance systems make repairs more complex and costly, which raises revenue per repair but also the investment needed in equipment and training.

    What Bankers Look For

    Across fitness, car washes and automotive services, bankers build the analysis from the site up.

    1

    Map the sites

    List every location with its opening date, size, ownership and competitors in its catchment.

    2

    Build cohorts

    Group sites by opening year to see how new sites ramp and where mature sites settle.

    3

    Measure members

    Track members, churn and pricing by site and by cohort of members.

    4

    Test new sites

    Compare recent openings with older ones on build cost, ramp and returns.

    5

    Roll up

    Add corporate overhead and real estate to reach company-level earnings and value.

    The analysis rests on the same building blocks in every format:

    • Site-level returns: build cost, ramp time and mature four-wall profit for new and acquired sites
    • Membership metrics: members, churn by cohort, membership share of revenue and price increases
    • Same-site sales, split into members or visits and price
    • Competitive density: competing sites and planned openings within each catchment
    • Real estate: owned versus leased sites and sale-leaseback capacity
    • Labor: staffing models and wage exposure, especially in collision repair

    The measurement of site returns is covered in four-wall EBITDA, new-unit returns and payback, and why recurring, membership-driven earnings tend to earn higher multiples than transaction-driven ones in what drives consumer valuation multiples. For a coverage banker, the essential test in consumer services is whether a business has truly turned visits into relationships: a chain whose customers return because they are members, not because they happened to drive past, is worth far more than one that must win each visit again.

    Interview Questions

    1
    Question #1Easy

    A car wash membership costs $25 a month with 40% contribution after the cost of serving the member, and 5% of members cancel each month. What is a member worth, and why do sponsors like membership models?

    A member is worth about $200 of contribution ($500 of revenue) over their life, before discounting.

    A member's lifetime value is the monthly contribution times the average life, which is roughly one divided by monthly churn:

    Member value≈Monthly contributionMonthly churn\text{Member value} \approx \frac{\text{Monthly contribution}}{\text{Monthly churn}}
    • •Monthly contribution: 40% x $25 = $10.
    • •Average life: 1 / 5% = 20 months.
    • •Member value: 20 x $10 = $200, from 20 x $25 = $500 of revenue.

    Churn is the biggest lever, so I would check it by joining cohort, split between voluntary cancellations and failed card payments.

    Sponsors like membership models for four reasons:

    1. 1.Recurring revenue: automatic monthly payments make revenue predictable, which supports leverage and a higher multiple.
    2. 2.Less weather exposure: members pay whether or not it rains.
    3. 3.Frequency and data: members visit more often and the operator knows who they are, which helps pricing, tier upgrades and retention.
    4. 4.Site returns: a site's value rises with its membership density, including acquired independents' customers converted to plans.
