Page speed ROI calculator
Estimate the extra revenue a faster website could earn each month and year.
What faster pages could earn
The ~7% conversion drop per extra second is an industry rule of thumb (Deloitte / Google studies); real impact varies by site — measure your own Core Web Vitals to confirm.
Indicative estimate based on a heuristic. Actual gains depend on your audience, device mix and where the slowdown occurs in the journey.
Why page speed affects revenue
Every extra second a page takes to load pushes more visitors to leave before they buy. Industry research from Deloitte and Google points to a rough rule of thumb: conversions can drop by around 7% for each additional second of load time. This calculator applies that heuristic to your own monthly revenue so you can size the opportunity.
Enter your current load time, a realistic target, and the revenue your site earns each month. The tool works out the seconds you could save, an estimated conversion uplift, and the extra revenue that speed could unlock over a month and a year. It is a directional estimate, not a guarantee, so treat the numbers as a starting point for a business case rather than a precise forecast.
It is an industry rule of thumb drawn from studies by Deloitte, Google and others linking load time to conversion rates. Real impact varies widely by site, audience and device, so measure your own Core Web Vitals to confirm.
