Windows & Doors Marketing Budget ROI Calculator
Find out if your lead generation is making you money or bleeding you dry.
Windows & doors contractors typically spend 5-15% of revenue on marketing, but many don't track true ROI. With average jobs worth $12,000 and long sales cycles, understanding your cost per customer vs lifetime value is crucial. A poorly optimized marketing budget can cost you $50,000+ annually in wasted ad spend or missed opportunities.
Enter your monthly marketing spend, lead volume, close rates, and job values. The calculator reveals your true cost per customer, profit margins, and exactly where to optimize for maximum ROI.

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
