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

Frequently Asked Questions

My garage door business is mostly emergency repairs. How does this affect these calculations?

Emergency repairs typically have higher close rates (70-80%) but lower average job values. Adjust your inputs accordingly, and consider that emergency work often leads to full door replacements later, increasing lifetime value significantly.

Should I include my truck wraps and uniforms in my lead generation cost?

Yes, include any marketing expenses that generate leads. Truck wraps, uniforms, yard signs, and business cards all contribute to lead generation. Estimate their monthly cost by dividing annual expenses by 12.

My close rate varies dramatically between spring repairs and full installations. How do I handle this?

Use a weighted average based on your typical job mix. Spring repairs might close at 80% but average $200, while full installations close at 40% but average $2,500. Calculate the blended rate based on your actual volume split.

How do I account for seasonal fluctuations in the garage door business?

Run this calculator for both peak season (June-July) and slow season (November-February) separately. Your winter numbers will likely show higher cost per lead but emergency repairs maintain cash flow. Plan your annual marketing budget accordingly.

What if most of my business comes from referrals and repeat customers?

If 60%+ of your business is referrals/repeat customers, focus on the LTV to CAC ratio and consider adding referral incentive costs to your lead generation budget. Your 'true' customer acquisition cost might be much lower than contractors relying on paid advertising.
