Funnel

  1. 1CPM = ¥50,000 ÷ 2,000,000 × 1000 = ¥25.00
  2. 2CTR = 30,000 ÷ 2,000,000 = 1.50% → CPC = ¥1.67
  3. 3CVR = 600 ÷ 30,000 = 2.00% → CPA = ¥83
  4. 4Revenue = 600 × ¥200 = ¥120,000
  5. 5ROAS = 120,000 ÷ 50,000 = 2.40

💡 *Breakeven ROAS = 1 ÷ gross margin — at 40% margin you need ROAS ≥ 2.5 just to break even. Typical funnel benchmarks (e-commerce): CTR 1-3%, CVR 2-5%, CPM varies wildly by platform (¥15-60 Douyin feed). Diagnose by stage: low CTR = creative problem; good CTR but low CVR = landing page/pricing problem; good ROAS but low volume = budget/targeting too narrow.
