What your ugly website costs you a month (the math, with your numbers)
A slow, phone-unfriendly site loses some of the people who were ready to call. With your own visitors, how many reach out and your average sale, the leak becomes a dollar estimate you can check, and a fix you can price.
The short answer: take your monthly visitors, the share who reach out, the share of those who buy, and your average sale. Then knock off the leads a slow or squished site loses. The gap is what ugly costs you. It is an estimate, and it is usually bigger than people guess.
Why a website leaks money
Most people who look you up do it on a phone: 73% of consumers did their last local business search on one (BrightLocal, 2026). And after good reviews, 54% go to your website next (BrightLocal, 2026). So your site is where ready customers land. A slow page, a desktop layout on a phone, or a number nobody can tap turns some of them around.
1. Start with what you have
Visitors a month (your website host or analytics shows it), the share who call or fill in a form, and how many of those buy. A plumber with 400 visitors, 4% who reach out and 30% who book has about 16 leads and 5 jobs a month from the site.
2. Price the leak, honestly
Speed: in Portent's study of lead-generation sites, conversion fell from about 40% at 1 second to 29% at 3 seconds (Portent, 2022). In a controlled test, Vodafone made its main content load 31% faster and sold 8% more (web.dev). We count 5 to 15% of leads lost for each second past 2.5 seconds, 10% likely. Phones and missing contact options lose more; those numbers are our assumption, so we say so.
3. Multiply it out
Leads lost, times the share who would have bought, times your average sale. Do it with a low, a likely and a high number, and keep the range. Anyone who hands you one exact dollar figure is guessing.
4. Compare it with the fix
Now you have a monthly leak and a one-time price for fixing it. Divide one by the other and you get how long the fix takes to pay for itself, by your own numbers.

Questions, answered
How much does a bad website cost a small business?
It depends on your visitors, how many reach out, how many buy and your average sale. A slow or phone-unfriendly site loses a share of those leads; the audit at audit.y00r.co estimates it with your numbers.
Does website speed really affect sales?
Yes, in the studies that measured it: Vodafone sold 8% more after making its pages 31% faster in a controlled test, and lead-generation sites convert less as load time grows.
Is the estimate a promise?
No. It is an estimate from your inputs and public research, shown with a range and its math. Fixing your site does not guarantee more sales.
