Assumptions

$7.00 to reach 1,000 people, in line with what social ads cost. The only number we choose. Everything else is measured.

Only original posts count. Retweets, replies, and quote tweets are left out: we price your own words, not what you amplified.

Impressions come straight from X. Where a post’s count is missing, we estimate its reach from engagement.
