How I calculate this
This model uses a 2.5 second baseline and assumes a 7 percent revenue difference for each extra second. These are fixed modelling assumptions, not a prediction for your business. Full load time and Largest Contentful Paint are different measurements.
illustrative uplift = visitors × conversion rate × average sale × min(0.07 × max(load − 2.5, 0), 0.6)
The model caps the illustrative uplift at 60 percent of current revenue. This cap is a calculator setting, not an established industry limit.
This is a what-if estimate, not a promise or evidence of lost revenue. Your real numbers depend on your market, your traffic quality, and your site.

This calculator is only as good as the load time you feed it. Run my free speed test to get your actual number, then let's talk about closing the gap. We can use the results to work out which improvements are worth making.
