The model, in plain English
Every extra second of load over a healthy mobile target (about 1.5 seconds) suppresses conversion by roughly seven percent — a heuristic from years of public speed-vs-conversion research. We cap that suppression at sixty percent so the model never overstates.
Plug in your visitors, current conversion rate, average customer value, and load time. The calculator shows the customers you close today, the customers you would close at a healthy load, and the gap. Multiplied by your average customer value, that gap is the monthly and annual dollar leak.
The result is illustrative because the inputs are yours. The free 48-hour Growth Audit replaces them with your real Google PageSpeed data and analytics, and names the three fixes that move the number most.
