Creator seeding budget vs paid amplification split worksheet (labelled synthetic)

Seeding without amplification math wastes both sides. TikTok Spark Ads document a format that boosts organic posts (including authorised creator posts) so engagement can accrue to the organic post while paid delivery runs. That is a format definition, not a recommended spend split.

Equations (labelled synthetic)

• seeding_cost = sum(creator_fees + product_gifts_cogs + agency)
• amplification_spend = media_spend_on_authorised_posts
• total = seeding_cost + amplification_spend
• seed_share = seeding_cost / total
• cost_per_authorised_post = total / authorised_posts
• Optional teaching KPI: blended_cpe = total / (organic_eng_during_window + paid_eng) — only if both engagement definitions are named.

Synthetic example

seeding_cost = 15500; total = 40500; seed_share = 0.3827; cost_per_authorised_post = 2025
