What moves your multiple

  • Recurring revenue (you: -). At 25%+ the calculator moves you up the band; at 50%+ further. Maintenance agreements, contracts and memberships count.
  • Owner dependence (you: -). Under 20 hours a week in the field or chair helps; under 10 helps most. Buyers pay for a business that runs without you.
  • Customer concentration (you: -). Keep any single customer under about 15% of revenue.

Next steps

  1. Recast your earnings line by line with the SDE calculator (tradeexitguide.com/tools/sde-calculator/).
  2. See what you would keep after taxes and fees with the after-tax proceeds calculator (tradeexitguide.com/tools/after-tax-proceeds-calculator/).
  3. Read your trade's valuation page for the sources behind the band and the drivers buyers cite.
  4. If you have an offer, compare it on guaranteed cash, not headline price (tradeexitguide.com/guides/unsolicited-pe-offer/).
  5. Before you sell, get a formal valuation from a credentialed appraiser or an experienced intermediary.

What moves the multiple for a car wash

Key metric buyers ask for: Wash format (self-serve, in-bay, express tunnel), unlimited membership count, cars per year, real estate owned or leased.

Pushes you toward the top of the range

  • Unlimited wash club members producing recurring monthly revenue
  • Express tunnel format with modern equipment
  • Owned real estate or a long lease on a high-traffic site

Pushes you toward the bottom

  • Aging equipment or a site that cannot fit a modern tunnel
  • New express competitors opening nearby
  • Environmental or water-discharge issues found in a Phase I

How buyers value a car wash

Small self-serve and in-bay washes sell on SDE. Express tunnels with memberships are bought by chains and investors who value membership revenue and the real estate; many deals separate the operating business from a sale-leaseback of the land.

Rule of thumb on revenue: About 1.0-3.0x revenue (BizBuySell sold middle half 1.03-3.01x). Use it only as a sanity check; buyers pay for cash flow they can finance.

Worked example: Blue Arrow Express Wash (fictional)

Fictional business for illustration. Revenue $900,000, SDE $320,000. Express tunnel, 2,400 unlimited members, land leased with 15 years remaining.

Frequently asked questions

What is a car wash worth?

Car washes sold on BizBuySell from 2021-2025 went for a median 5.18x SDE (middle half 3.20-6.70x) and about 2.0x revenue, the highest of any service category we track. Format and real estate explain most of the spread.

Do buyers need an environmental report?

No. It is an educational estimate built from published data. Lenders, courts and the IRS may require a credentialed appraisal; see appraisal vs estimate.
