Plumbing Service
Financial Model

How Do You Model Revenue?

Your revenue is driven by the number of active customers, their average billable hours per month, and your price per hour for each service. The model starts with a $15,000 marketing budget in 2026 and a customer acquisition cost (CAC) of $150 to acquire new customers. These customers are then allocated across your service mix, which initially leans toward high-urgency jobs like Emergency Repairs (70% of new customers) billed at $150/hour.

Key Revenue Streams

• Emergency Repair
• New Installation
• Maintenance Plan
• Diagnostic Service

What's the Path to Profitability?

The business is projected to see a net loss in its first year, with an EBITDA of -$91,000 as you ramp up operations and marketing. However, the model shows a turn to profitability in year two, with a positive EBITDA of $92,000. This growth continues, reaching an EBITDA of $1.46 million by year five. This trajectory in the plumbing profitability analysis depends on scaling your customer base while managing direct costs for parts (starting at 15% of revenue) and fixed overhead of around $5,000 per month.

Levers for Improving Profit

• Increase recurring revenue from maintenance plans
• Optimize marketing spend to lower CAC
• Improve job efficiency to reduce billable hours per task
• Negotiate better pricing on parts and fixtures
