Speed Impact
Your 4s load time is costing you 14.0% in conversions. Every second above 2s loses you ~7% of potential sales.
How We Calculate This
Speed Loss: Google research shows 7% conversion loss per second of load time above 2 seconds.
Bounce Rate: High bounce rates indicate lost opportunities. We calculate impact above the 40% benchmark.
Mobile Gap: Mobile typically converts 40% lower than desktop. Optimization can recover ~30% of this gap.

Frequently Asked Questions
How does website speed affect conversions?
According to Google research, every second of page load time above 2 seconds results in approximately 7% loss in conversions. A website loading in 5 seconds loses about 21% of potential conversions compared to one loading in 2 seconds.
What is a good page load time for e-commerce?
Google recommends pages load in under 2 seconds for optimal user experience. For e-commerce sites, Amazon found that every 100ms of latency cost them 1% in sales. Industry benchmarks suggest 2-3 seconds is acceptable, but under 2 seconds is ideal.
How does bounce rate impact revenue?
A high bounce rate means visitors leave without engaging. The industry benchmark is around 40%. For every percentage point above this benchmark, you're losing potential conversions. A 60% bounce rate vs 40% could mean 10% less revenue.
Why do mobile users convert less than desktop?
Mobile users typically convert at 60% of the desktop rate due to smaller screens, slower connections, and more distractions. However, with proper mobile optimization (responsive design, simplified checkout, faster loading), you can recover up to 30% of this conversion gap.
How is the opportunity cost calculated?
The calculator uses three factors: Speed loss (7% per second above 2s based on Google data), bounce rate impact (revenue loss from rates above 40% benchmark), and mobile optimization gap (potential recovery from the 40% mobile-desktop conversion gap). These are combined to show your total monthly revenue loss.
What can I do to improve website speed?
Key improvements include: optimizing and compressing images (WebP format), enabling browser caching, minifying CSS and JavaScript, using a CDN for global delivery, implementing lazy loading, and choosing faster hosting. Professional optimization can improve load times by 50-70%.
