About this calculator
The estimates are based on McKinsey Global Institute research finding that knowledge workers spend an average of 2.6 hours per day reading and answering email. A 70% reduction reflects the typical result when AI handles triage, summarization, and noise filtering — leaving only emails that genuinely require your attention.
