What are the core revenue drivers?

Revenue is driven by the number of active customers and the billable hours for each service. The model calculates customer acquisition based on your marketing spend (starting at $45,000 annually) and a declining Customer Acquisition Cost (from $450 down to $350). This structure allows you to see exactly how marketing investment translates into revenue, which is projected to grow from $580,000 in the first year to $4,156,000 by the fifth.

Key Revenue Streams

• Attic Insulation: Initially 65% of your service mix.

EBITDA margins expand significantly, from a slim 0.2% in Year 1 to a very healthy 44.7% by Year 5, demonstrating strong operating leverage as you scale.
