Page Speed Revenue Impact Calculator
A sizing exercise, not a promise.
Published speed-to-conversion relationships vary widely and are correlational — fast sites tend to be well-built sites generally. Use this to size whether the engineering work is worth scheduling, not as a forecast.

Frequently asked questions
Does page speed really affect conversion?
The correlation is well documented and the direction is consistent. The size of the effect varies enormously by site and traffic mix, and much of the published research comes from companies selling speed products.
How much conversion per second?
Figures between 2% and 20% per second appear in the literature. That range is too wide to plan against precisely, which is why this should size a decision rather than forecast a result.
What should I fix first?
Largest contentful paint on mobile, usually — images and render-blocking resources. It is the metric most closely tied to the perception of speed.
Does speed affect search rankings?
It is a ranking signal, though a modest one relative to relevance. The conversion effect is generally the larger commercial argument.
