Frequently Asked Questions

What does the Consent Cost Calculator measure?▾
It estimates how much analytics data you lose when visitors reject cookie consent banners. It detects your CMP (consent management platform), analyzes which trackers require cookies, and calculates the percentage of visitor data you cannot capture.
How is data loss calculated?▾
Data loss = 1 - (consent acceptance rate x (1 - browser block rate)). The browser block rate accounts for users with ad blockers and privacy browsers that block trackers regardless of consent. We use an industry average of 12%.
What do the grades mean?▾
Grade A means less than 15% data loss (excellent). Grade B is 15-30% (good). Grade C is 30-45% (moderate). Grade D is 45-60% (poor). Grade F means over 60% data loss (critical).
How accurate are the consent acceptance rates?▾
We use industry-average acceptance rates for each CMP based on published benchmarks. Actual rates vary by geography, industry, banner design, and user demographics. The estimates provide a reasonable baseline for planning.
What is the difference between cookie-based and cookieless trackers?▾
Cookie-based trackers (like GA4, Facebook Pixel) require user consent under GDPR/ePrivacy. Cookieless trackers (like Plausible, Fathom) do not use cookies or personal data, so they capture data from all visitors regardless of consent.
How can I reduce data loss?▾
Switch to cookieless analytics (Plausible, Fathom, Umami), optimize your consent banner for higher acceptance rates, use server-side tracking where legally permitted, or implement consent mode to capture anonymized data from non-consenting users.
Does this tool check GDPR compliance?▾
No. This tool estimates data loss from consent mechanics. It does not verify legal compliance. Consult a privacy professional for GDPR/ePrivacy compliance advice.
