The five tools use different fee structures, fixed costs, and decision questions. Defaults are editable starting points; every model exposes its verification date, official sources, and known limits.
- 5 independent fee models
- 15 official-source records
- 3-step reproducible workflow
| Model | Variables modeled separately | Decision answered | Last checked |
|---|---|---|---|
| TikTok Shop US | Platform fee, creator commission, CNY cost, ads, logistics, samples, and returns | Are organic, creator-led, and paid orders profitable on their own? | |
| Amazon FBA | Referral fee, FBA fulfillment, storage, inbound placement, ads, and returns | Does the current price cover the ASIN's unit costs and target margin? | |
| Etsy | Transaction, country payment, Offsite Ads, listing, and buyer shipping | How much profit separates organic, 12%, and 15% ad-attributed orders? | |
| Shopify | Payment, third-party transaction, plan/app allocation, CAC, and returns | Does the store keep its target margin across gateways and order volumes? | |
| PayPal / Stripe | Percentage rate, fixed fee, order value, and monthly transaction count | At which order values do PayPal and Stripe effective rates diverge? |
