Ad Blocker Revenue Loss Calculator
Estimate how much display-ad revenue your site loses to ad blockers — the gap between blocked pageviews and what you could be earning.
How it works
Blocked views = pageviews × block rate · Lost revenue = (blocked views ÷ 1,000) × RPM · Captured = potential − lost
Ad blockers strip the ads from a page, so those visits earn nothing even though they still consume bandwidth. The revenue lost is simply the blocked share of your pageviews run through your ad RPM. Ad-block adoption skews high for technical and younger audiences — 25–40% is common on developer and gaming sites — so a content business can be leaving a quarter of its potential ad income on the table. That gap is why many publishers ask blocker users to allowlist the site, subscribe, or accept a paywall.
Worked example
A site gets 500,000 monthly pageviews at a $6 RPM, for $3,000 of full potential. A 25% ad-block rate means 125,000 views show no ads: 125,000 ÷ 1,000 × $6 = $750 lost per month, or $9,000 a year. The site actually captures $2,250 of the $3,000.
Frequently asked questions
How do I find my real ad-block rate?
Compare your ad server’s recorded impressions against your analytics pageviews, or run a small ad-block detection script. Rates vary hugely by audience — mainstream lifestyle sites may see under 10%, while tech and gaming sites often exceed 30%.
Do blocked visitors cost me anything?
Yes — they still consume server bandwidth and CDN transfer while generating no ad revenue, so heavy ad-block traffic raises your cost-per-earning-visitor. That is part of why the lost revenue stings twice.
What can I do about ad-block losses?
Common tactics are polite allowlist requests, ad-block-aware paywalls or metered access, offering an ad-free paid subscription, and diversifying into sponsorships or affiliate income that blockers do not strip. This calculator sizes the problem so you can judge whether it is worth acting on.
