How do you calculate marketing ROI?

Marketing ROI = (Revenue from marketing - Marketing cost) / Marketing cost x 100. Our calculator factors in your industry's average conversion rates, close rates, and customer lifetime value to give you a realistic projection, not a best-case fantasy.

What's a good marketing ROI?

A 5:1 revenue-to-spend ratio (500% ROI) is considered strong. A 10:1 ratio is exceptional. Anything below 2:1 is typically not profitable after accounting for COGS and overhead. AI-powered campaigns often achieve 6-8x by reducing waste and improving targeting.

How long before I see ROI from marketing?

Paid channels (Google Ads, Meta) can show ROI within 2-4 weeks. SEO typically takes 3-6 months. AI automation shows ROI within 1-3 months through cost reduction alone. The calculator helps you model each scenario.

How to Calculate Your Marketing ROI

Every dollar you spend on marketing should be traceable to revenue. This calculator uses your actual business metrics, monthly spend, lead volume, close rate, and average deal size, to project realistic returns across different marketing channels.

Most businesses guess at their marketing ROI. The problem: without real numbers, you can't tell which channels are profitable and which are burning cash. This calculator eliminates the guesswork.

What affects your marketing ROI

Cost per lead: Google Ads averages $50-150 for service businesses; SEO leads cost 60% less long-term
Lead-to-customer rate: Industry average is 2-5%; AI-powered follow-up pushes this to 8-15%
Customer lifetime value: A single HVAC customer is worth $8,000+ over 10 years, not just the first $300 repair
Speed to lead: Responding within 5 minutes increases conversion 21x compared to 30-minute response times

Why AI changes the ROI equation

Traditional marketing ROI is capped by human speed. AI removes the bottleneck: instant lead response at 2 AM, automated qualification before your team even sees the lead, and personalized follow-up sequences that run 24/7. Businesses using AI-powered marketing see 30-50% higher ROI from the same ad spend.
