Methodology & Assumptions

This calculator models the complete marketing funnel for windows & doors contractors, accounting for lead response time impact (5-minute response converts 2.5x better than 1-hour), seasonal demand variations (30% higher in peak season), and lifetime value including referral multiplier effects. It calculates true ROI by measuring net profit after marketing costs rather than just revenue multiples.

Assumptions:

Lead response time significantly impacts close rates based on industry studies
Referral customers have 80% of the value of direct customers when accounting for acquisition costs
Seasonal patterns follow typical home improvement demand cycles
Profit margins exclude marketing costs to show true marketing ROI

Limitations:

Does not account for cash flow timing differences between marketing spend and project completion
Assumes consistent lead quality across all marketing channels
Does not factor in competitive market dynamics or pricing pressure

Frequently Asked Questions

Why does response time matter so much for windows & doors leads?

Windows & doors is a high-consideration purchase where customers contact multiple contractors. Studies show leads contacted within 5 minutes are 9x more likely to convert than those contacted after 30 minutes. Since customers often go with the first contractor who provides a professional, timely response, speed is crucial for your close rate and overall ROI.

My numbers vary dramatically by season - how should I interpret these results?

The calculator includes seasonal adjustments, but you should run it for each season separately. Peak season (June-July) typically sees 30% higher close rates due to increased urgency, while slow season requires 40% lower marketing spend to maintain the same ROI. Plan your annual budget accordingly - invest heavily in spring/summer, pull back in winter.

I do mostly commercial work with much higher job values - are these benchmarks still relevant?

Commercial window/door projects have different metrics: longer sales cycles (3-6 months), higher close rates (35-45%), but much higher cost per lead ($150-300). The ROI principles remain the same, but adjust your expectations - commercial leads take longer to convert but are worth much more when they do.

How do I account for jobs that come from referrals vs paid marketing?

The calculator includes referral value by applying an 18% referral rate to your lifetime value calculation. However, track referrals separately - they typically convert at 60-80% rates with zero acquisition cost. If more than 30% of your business comes from referrals, you may be under-investing in marketing and missing growth opportunities.

What if I'm spending on multiple marketing channels with different costs per lead?

Enter your blended averages, but track each channel separately in your business. Google Ads might cost $45/lead at 25% close rate, while Facebook could be $65/lead at 18% close rate. The calculator shows your overall performance, but optimize by shifting budget from expensive, low-converting channels to profitable ones.
