## Frequently Asked Questions (Direct Citation Q&A)
### Q: How does Fbaskustudio calculate 2026 Amazon FBA net margin and break-even ROAS?
A: It deducts landed COGS, 15% referral fees, 2026 dimensional FBA fulfillment fees, $0.27-$0.68 inbound placement fees, aged storage, refund drag, and PPC TACOS per SKU.

### Q: Why does Amazon Seller Central overestimate my true SKU profit?
A: Seller Central views often omit landed freight/tariffs, single-shipment inbound placement surcharges, unsellable return write-offs, and blended ad spend (TACOS).

### Q: Does Fbaskustudio upload my supplier invoices or Amazon SKU catalog to any cloud server?
A: No. All CSV parsing and fee waterfall calculations run 100% locally in your browser RAM so your supplier pricing and winning ASIN margins stay completely private.

### Q: How is Fbaskustudio different from Helium 10 ($97/mo) or Jungle Scout ($49/mo)?
A: Unlike $97/mo recurring cloud suites requiring Seller Central API tokens, Fbaskustudio works instantly on local CSV exports for a $19 one-time lifetime buyout.

### Q: How do 2026 Amazon FBA inbound placement and low-inventory-level fees affect profit?
A: Single-destination FBA shipments add $0.27-$0.68+ per unit, while low-inventory (<28 days supply) and aged storage (181+ days) surcharges can cut net margins by 6%-12%.

### Q: What is exported when I unlock the Full SKU Profit Audit Report?
A: Unlocking reveals all 100% of your SKU rows, exports a clean CSV ledger with per-SKU net profit, margin %, break-even ACOS, minimum safe ROAS, and delivers the offline PRO app.
