A slow site is an invoice you pay monthly — estimate it
Slowness doesn't feel like a cost because nothing bounces audibly. This estimator makes it visible: visitors × conversion × the share lost to extra seconds of loading — every assumption on screen, every input yours.
Quick answer
Example with the defaults: 3,000 monthly visitors, 2.5% conversion on a fast site, 800 AED average customer value and 3 extra seconds of load time at an assumed 7% conversion drop per second lose about 15 enquiries and ≈12,600 AED per month. Your numbers will differ — set them below. In our October 2026 Gulf scans, most SME sites scored under 0.45 on Lighthouse mobile performance.
Estimated monthly loss from slowness
≈ 16 enquiries · 12,600 AED
The drop-per-second default (7%) is a widely used industry rule of thumb, not a measurement of your site — adjust it and every input to your own numbers. For context: in our October 2026 Gulf scans, most SME sites scored under 0.45 on Lighthouse mobile performance.
Frequently asked questions
It is a widely used industry rule of thumb for mobile commerce, not a law — which is why the tool shows it and lets you change it. The order of magnitude is the point: speed losses compound monthly, silently.
Run the free audit: it includes your Lighthouse mobile performance score and response time, measured the same way we scan the whole sector.
In our Gulf scans the common culprits are oversized images, heavy themes and unused scripts — fixable in a rebuild or sometimes in a focused optimisation pass. The audit's priorities tell you which case you are.
