Collab Post Engagement & Revenue Split Formula

Calculates total engagement rate and splits sponsorship revenue proportionally by each creator's follower count.

Total Engagement = Likes + Comments + Shares + Saves
Engagement Rate = (Total Engagement ÷ Total Reach) × 100
Creator A Share = Creator A Followers ÷ (Creator A Followers + Creator B Followers) × 100
Creator A Earnings = Sponsorship Fee × Creator A Share %

Revenue split is based on follower contribution. Cost per engagement helps evaluate overall campaign efficiency.
