Broken links rarely show up as a line item. A visitor clicks a dead internal link, lands on a 404 page, and a share of them simply leave. Nobody logs that as lost revenue, so the fix keeps sliding down the backlog behind things with a clearer number attached. This calculator gives the problem a number you can put in front of whoever owns the roadmap.

The math is deliberately simple and every rate comes from you. It takes your monthly sessions, the share of sessions that hit a broken link or 404, and the share of those visitors who abandon instead of finding their way back. Those lost sessions are multiplied by your normal conversion rate and your average value per conversion. There are no hidden industry benchmarks; if you change a rate, the estimate changes with it.

How to use this tool

Pull monthly sessions and your site conversion rate from your analytics tool for the last full month.
Divide 404 page views by sessions to get the share of sessions that hit a broken link, then read the exit rate on the 404 page for the abandon share.
Enter your average order value or lead value and read the monthly and yearly loss, then compare it against the cost of running an audit and fixing the links.

What the math assumes

Assumes visitors who abandon after hitting a broken link would otherwise have converted at your site wide conversion rate.
Assumes an abandoned session is fully lost; it does not model visitors who come back later through search or a bookmark.
Assumes the value per conversion you enter is average revenue or lead value, not lifetime value.
The yearly figure is the monthly estimate multiplied by 12 with no seasonality applied.
No industry benchmarks are baked in; every rate in the result comes from the numbers you enter.

Frequently asked questions

Where do I find how many sessions hit a broken link?

The quickest source is the page view count for your 404 template in analytics, divided by total sessions. A crawl based link audit gives a more complete picture because it also catches links to pages that return errors without ever being visited.

Why does the calculator ask for an abandon rate instead of assuming one?

Because it varies a lot between sites. A 404 page with a search box and useful links keeps far more visitors than a bare server error, so your own exit rate on that page is more honest than any published average.

Does this include lost search rankings from broken links?

No. It only counts visitors who are on your site and leave because of a dead link. Ranking effects are real but too indirect to put a reliable dollar figure on, so they are left out rather than guessed.
