Exterior wash revenues and costs climb as segment shows signs of maturing

Exterior car wash operators have seen both revenue and expenses climb steadily over the past decade, but the most recent data suggests the segment may be settling into a more mature, slower-growth phase. That analysis comes from consultant Robert Roman, drawing on operator survey data published by Auto Laundry News covering report years 2013 through 2026.

The typical exterior wash profiled in the surveys handles an average daily traffic count of 28,000, operates seven days a week, and pulls most of its customers from within a five-mile radius. Spring is the busiest season, more than half of business lands between Friday and Sunday, and most operators face at least three competing washes in their market. The average conveyor now exceeds 110 feet.

Revenue growth plateaus

Since 2013, average gross revenue per car has risen by $4, an increase of roughly 75 percent. The surveys show, however, that the last three years have leveled off. Roman attributes the plateau to several forces working together: market maturity, lower inflation, consumer price resistance, and the broad adoption of wash membership clubs.

Long-term car counts have trended upward even as annual volume has fluctuated year to year. The combination points to a segment where growth is still present but no longer accelerating.

Costs keep rising, especially labor

On the expense side, cost of goods has held steady at around 25 percent of total cost, covering credit card processing, chemicals, utilities, and equipment maintenance. Operating expenses run near 35 percent of total cost. The sharpest movement has been in labor, which has climbed from about 15 percent of sales revenue to more than 23 percent.

Pay scales illustrate the shift. In 2013, more than 65 percent of operators paid at least $10 per hour. Today, 47 percent pay $15 or more, and 20 percent pay above $20.

Technology and marketing adoption have advanced as well. Nearly 90 percent of respondents maintain a website, and all of them promote their business on social media. Mobile payment acceptance has jumped to more than 63 percent, up from 22 percent in 2022, and over 80 percent now offer premium coatings such as ceramic.

Operator sentiment, meanwhile, is divided. Responses on the segment's current and future state split evenly between positive and negative views, with descriptions ranging from robust to stale and optimistic to stagnant. Roman notes that some industry observers read this split as a signal that the industry has entered a more mature phase shaped by saturation, competition, and economic pressure.

Why it matters for operators

The central message in the data is that operators can no longer count on a rising tide to lift their business. With per-car revenue flattening and labor costs now consuming nearly a quarter of sales, margins depend increasingly on execution within each individual market rather than on broad industry expansion.

That puts a premium on controllable factors: tight cost management on chemicals and utilities, disciplined labor scheduling, and retention-focused membership programs that stabilize revenue in a saturated field. The steep rise in wage floors means labor planning and automation decisions carry more weight than they did even a few years ago. Operators who treat the current environment as a competitive, share-of-market battle rather than a growth story will be better positioned as the segment matures.
