What is a slow site
costing you?
Slow pages don't announce themselves. They just quietly send would-be customers to a competitor. Put your own numbers in and see the sales a sluggish site may be costing you.
These figures are planning estimates, not a quote. Every project is different. The numbers use Stonekept's published pricing as a baseline; for an exact price, tell us what you need and we'll send back a fixed proposal.
A slow website is a leaky bucket
Every second a page takes to load, more visitors give up and leave. Each one who leaves is a sale that quietly didn't happen. It rarely shows up as a dramatic problem; it just means the phone rings a little less than it should. That's what makes it easy to ignore and expensive to keep ignoring.
The calculator above puts a number on it using your traffic and margins and a lift you choose, not a statistic we made up. When you're ready to see where your site actually stands, run it through our free speed test, then read how we build for speed and security from the ground up.
Good to
know.
How much does website speed really affect sales?
Enough to matter. Faster pages are consistently linked to higher conversion rates and lower bounce, because visitors, especially on phones, abandon slow pages quickly. The exact effect depends on your audience and site, which is why this tool lets you set your own expected lift rather than quoting a single figure as gospel.
Where do the numbers in this calculator come from?
From you. Your monthly visitors, your conversion rate, your average customer value, and a conversion-lift estimate you control. We don't bake in any invented statistics. The tool just does the arithmetic so you can see the scale of what a slow site may be costing.
