Margins are real and among the highest in small business
Laundromats consistently post 35-38% seller's discretionary earnings margins. That puts them at the top end of the small business universe; most service businesses run 15-25%, restaurants run 5-15%. The margin holds because the operating model is mostly fixed costs: rent, utilities, and equipment maintenance. Once volume covers those, additional revenue drops to the bottom line. The catch is the reverse is also true: a laundromat doing 60% of break-even volume is bleeding cash, and recovery requires either marketing-driven volume growth or rent renegotiation. Buyers should look at three-year trended utility costs and revenue per turn. These are the two metrics that show whether the business is healthy or in slow decline.
