Quick Reference & Frequently Asked Questions
How does Fbaskustudio calculate 2026 Amazon FBA net margin and break-even ROAS?
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.
Why does Amazon Seller Central overestimate my true SKU profit?
Seller Central views often omit landed freight/tariffs, single-shipment inbound placement surcharges, unsellable return write-offs, and blended ad spend (TACOS).
Does Fbaskustudio upload my supplier invoices or Amazon SKU catalog to any cloud server?
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.
How is Fbaskustudio different from Helium 10 ($97/mo) or Jungle Scout ($49/mo)?
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.
