Car Wash P&L Template

Enter your current month's revenue by source: retail wash sales by package tier, membership revenue, fleet billing, and any detailing or add-on income. Then fill in expenses using your chemical supplier invoices, payroll records, and utility bills. The Service Mix Analysis sheet is worth filling out in parallel — enter your car count by package type and the sheet calculates your average ticket and revenue per service automatically. These two numbers tell you far more than total revenue alone.

The categories that matter most in a car wash P&L are the ones that move fastest. Chemicals and supplies fluctuate with volume and vendor pricing — knowing your chemical cost per car lets you renegotiate supplier contracts or adjust wash pricing before margins compress. Labor costs depend heavily on your wash format: a full-service tunnel may run 25–35% of revenue in labor while an in-bay automatic runs closer to 8–12%. Membership revenue, once you've built a base, carries near-zero variable cost — tracking it separately from retail washes shows you the true leverage in your business model.
