Amazon FBA
Start here when fulfillment and platform costs dominate the model
This preset includes heavier freight and fixed platform costs to help you quickly test whether an FBA structure still supports the current price.
01
Put the key cost drivers into one margin view
Selling price, discounts, returns, platform fees, ad spend, and taxes are calculated together so you do not stop at gross margin.
02
Start quickly with multi-platform presets
Use built-in starting templates for Amazon, TikTok Shop, Shopify, Etsy, and Temu, then adjust them to match your own assumptions.
03
Freight and dimensional weight stay in sync
The workspace shows chargeable weight, per-shipment freight, and monthly freight cost together so packaging and logistics risk are easier to spot.

Read The Result
How to read the model faster
- Start with net margin and break-even price to see whether the current selling price has enough room.
- Then check the downside case. If the model still stays profitable with higher ad rate and return rate, the SKU is usually more resilient.
- Finally compare chargeable weight and per-shipment freight to see whether packaging or logistics is eroding the margin.
