Methodology & Assumptions
This calculator measures true business health by factoring in response time impact on close rates (leads contacted within 1 hour close at 2x the rate of those contacted after 24 hours), lifetime value including repeat business and referrals, and the full cost of customer acquisition including lead decay.
Assumptions:
- Response time significantly impacts close rates based on garage door industry data
- Repeat customers generate 1.5x average job value over their lifetime
- Each referral represents 0.8x the value of the referring customer
- Profit margins include all overhead and operating expenses
Limitations:
- Does not account for seasonal fluctuations in garage door demand
- Assumes consistent lead quality across all sources
- Does not factor in commercial vs residential job mix differences
