How do I calculate enterprise SEO ROI?

The formula for Enterprise SEO ROI is:

📌 SEO ROI (%) = [(Revenue from SEO – SEO Investment) ÷ SEO Investment] × 100

If an enterprise spends $100,000 annually on SEO and generates $1,500,000 in revenue, the SEO ROI would be:

📌 (1,500,000 – 100,000) ÷ 100,000 × 100 = 1,400% ROI
