Steps

1Platform = ¥129 × 5.0% = ¥6.45; ads = ¥25.80
2Gross = 129 − 6.45 − 25.80 − 45 − 6 = ¥45.75
3Refund drag: 10% × (shipping + ads ¥31.80) = ¥3.18/order
4Net = 45.75 × 0.90 − 3.18 = ¥38.00
5Breakeven ROAS = 1 ÷ (1 − platform − cost ratio) = 1.80 — any ad ROAS below this loses money

💡 The silent killer in e-commerce is the refund drag: a 25% refund rate doesn't just lose 25% of revenue — you still pay shipping and ads on those orders. "GMV vanity" hides this: ¥1M GMV at 3% net margin = ¥30k, less than a salary. Track net profit per order, not GMV. Apparel refund rates hit 30-50% on some platforms — model it honestly.
