Generated with the RevPages SaaS SEO ROI calculator — app.revpages.ai

The estimated total revenue generated by one customer over their entire relationship with your business. Use revenue LTV, not profit LTV.

SEO investment versus estimated customer lifetime revenue
- Total SEO investment: £36,000
- Estimated customer lifetime revenue: £75,000
SEO spend covers the selected period. Estimated lifetime revenue includes future revenue from customers acquired during that period.
How this is calculated
(Estimated customer lifetime revenue − SEO investment) ÷ SEO investment × 100
(£75,000 − £36,000) ÷ £36,000 × 100 = 108.3%
