How It Works
We work out your current monthly revenue from visitors, conversion rate, and value per conversion. Then we estimate the conversion rate you'd have at your target speed by removing the loss attributed to each second your site sits above that target. The gap between the two is the revenue a faster site could recover. Every assumption is shown below the results, and you can edit the core loss factor yourself.
Fair Questions
Where does the 'lost revenue' figure come from?
It compares your conversions at your current load time against what they'd likely be at a faster target time. The model assumes each extra second above your target trims conversions by a set percentage — an industry estimate you can adjust. It's a directional estimate, not a promise.
Is it really true that speed affects sales?
Yes — study after study links faster pages to higher conversion rates and lower bounce. The exact impact varies by site, which is why this tool shows its assumption openly and lets you change it.
What's a good target load time?
Under two seconds is a solid goal for most local-business sites, and under one second is excellent. The default target here is 2.0 seconds.
How do I find my current load time?
