What is a slowsite costing you?
Slow pages quietly lose sales. Plug in your traffic, conversion rate, and load time to see the revenue you could be leaving on the table — and what a faster site could recover.
That's about $50,400/year and roughly 42 extra sales/leads a month you could recover by getting from 4s down to ~1s.
Estimate only. Based on the well-cited industry average that conversions fall ~7% per extra second of load time; uplift is capped at 40%. Your real numbers depend on your audience and offer.
The math behind the number.
The estimate uses a well-cited industry average: conversions fall about 7% for every extra second a page takes to load. We compare your current load time to a fast ~1-second target and project the difference.

Visitors × conversion rate × value tells us what you earn today.

Every second over ~1s shaves roughly 7% off conversions.

Speed is revenue.
Every extra second of load time costs you visitors, conversions, and search rankings. The numbers are consistent across years of research.

Questions, answered.
It starts from your baseline — monthly visitors × conversion rate × value per sale. Then it applies a widely cited industry average: conversions drop about 7% for every additional second of load time. It compares your current load time to a fast ~1-second target and projects the revenue that gap represents, capped at a conservative 40% uplift.
It’s a long-standing benchmark from studies by Akamai, Google, Deloitte, and others showing conversion rates fall roughly 7% for each extra second of load time, with mobile bounce rising sharply past three seconds. It’s an average — your real numbers depend on your audience and offer — which is why we label the result an estimate.
Run our free speed test first to get your real mobile and desktop load times, then plug the number in here. If you’re guessing, most page-builder and off-the-shelf sites land between 3 and 7 seconds on mobile.
Yes — it’s completely free, requires no email, and runs entirely in your browser. Nothing you type is sent anywhere or stored.
The usual wins are optimized images, far less JavaScript, smart caching, and a modern framework instead of a heavy page builder. Often a purpose-built site is faster — and cheaper over time — than patching a slow one. That’s exactly what we do, targeting a 95+ PageSpeed score on every build.
