Website Cost Calculator: What Is Your Website Costing You?

What is your website costing you?

Plug in four numbers you probably already know. You’ll see roughly how much business slips away when visitors land on your site and leave without calling, booking, or filling out a form.

Find this in Google Analytics or your website platform’s stats. A rough number is fine.

Calls, form fills, emails, and bookings that come from the site. Best guess is okay.

Think of the last 10 people who called or filled out a form. How many ended up buying?

How the math works

Your site’s conversion rate is the share of visitors who reach out. Right now that’s your monthly inquiries divided by your monthly visitors. The calculator compares it to the rate you picked for a well-built site, using the same traffic, the same share of inquiries that become customers, and the same customer value.

Missed revenue = (visitors × target rate − current inquiries) × share who become customers × customer value

It doesn’t assume more traffic. The gap comes only from turning more of the visitors you already have into conversations. Things that commonly hold that number down:

  • The site is hard to use on a phone, where most local searches happen.
  • Pages load slowly, so people leave before they see anything.
  • There’s no clear next step, like a call button or a short form.
  • Nothing shows proof, such as reviews, photos of real work, or prices.
  • It looks dated, so visitors wonder if you’re still open.

This is an estimate, not a promise. Real results depend on your market, your offer, and how you follow up. But if the number surprised you, it’s worth a closer look.
