Website Loading Time & Cost Calculator

A SaaS tool that helps developers and marketers understand the real cost of slow page loads — both in user experience and actual business impact (bounce rates, conversions lost). Users input their traffic and current load times to see concrete metrics on how speed affects their bottom line.

Core Web Vitals became a Google ranking factor in 2021, and with LCP, INP, and CLS now firmly embedded in SEO workflows, there's genuine ongoing demand from both developers and non-technical marketers who need to translate performance data into business language their stakeholders understand. No clear incumbent owns this specific framing — tools like GTmetrix and PageSpeed Insights measure speed but don't convert it into revenue impact, which is the gap here. The $500–2k/mo revenue band is realistic but tight, pointing to a lead-gen or freemium model rather than direct subscription, since most users will treat this as a one-time calculator rather than a recurring tool. The biggest risk is exactly that: it's a calculator, not a workflow, so retention is near zero and growth depends entirely on SEO or viral sharing, which is a fragile foundation for even a modest SaaS business.
