Methodology & Assumptions
This calculator accounts for the unique economics of plumbing businesses by factoring in response time decay rates (leads lose 50% close probability after 1 hour), seasonal demand variations (winter emergencies vs. summer maintenance), and the 60% lifetime value multiplier from repeat customers and referrals typical in plumbing services.
Assumptions:
- Response time decay follows documented plumbing industry patterns with 50% close rate reduction per hour delay
- Seasonal multipliers based on emergency call volume data from home services platforms
- Lifetime value calculated using 35% repeat rate and 25% referral rate typical for quality plumbing contractors
- Profit margins include overhead allocation but exclude owner labor compensation
Limitations:
- Does not account for commercial vs. residential lead value differences
- Seasonal adjustments are generalized and may vary significantly by geographic location
- Formula assumes consistent lead quality across all marketing channels
