What can a broken website lead path cost each month?
Use your own numbers. This calculator does not promise lost revenue; it shows the economic exposure when calls, forms or booking paths fail.
Estimate only. Actual outcomes depend on traffic quality, seasonality, offer, sales handling, attribution and the exact failure. Use gross profit—not revenue—when making budget decisions.
Simple enough to challenge. Useful enough to prioritize.
Leads at risk = visitors × normal conversion rate × failure rate.
Sales at risk = leads at risk × close rate.
Gross revenue exposure = sales at risk × average sale value.
The customer usually does not report the problem.
Dead phone links
The number looks correct, but tapping it does not initiate a call or routes to the wrong line.
Silent form failure
The visitor sees a confirmation while the submission never reaches the inbox or CRM.
Mobile obstruction
Overlays, chat widgets or layout shifts cover the primary action.
Server instability
Intermittent 5xx responses lose only some visitors, making the defect easy to dismiss.
