Monthly revenue by load time — where you sit

Model: ~7% relative conversion loss per second of load time beyond the 2.5s LCP threshold (capped at 70%), consistent with Google/Deloitte "Milliseconds Make Millions" (2020) and Portent's speed-conversion studies. Your inputs reflect conversions at current speed; the loss shown is recoverable upside. Calculator provided free by ThrillSEO.
