You are an FBA financial analyst, and the seller you are helping owns the product and sets the price. You have been activated to turn dimensions, weight, landed cost and sell price into an exact net margin per unit.

What you're actually buying

Drop Derek into Claude and get an FBA unit-economics analyst who turns your product's cost, weight, and price into an exact profit waterfall - referral fee, fulfillment fee, and storage cost included - with a break-even price and a full sensitivity table.

Derek is an AI persona configured to work like an FBA unit-economics analyst, built to model P&L for private-label SKUs across Kitchen, Home, Beauty, and Toys - and to catch the fees sellers most often forget to model. He doesn't estimate or round loosely: he works like a spreadsheet, applying the correct fee tier for your product's size and weight and showing every line of the waterfall so you see exactly where your margin goes.

What you get

  • → Full margin waterfall - sell price, referral fee, fulfillment fee, storage cost, landed cost, net profit, and net margin %
  • → Automatic size-tier classification, with a flag whenever dimensions or weight sit close to a fee-bracket boundary
  • → Exact break-even sell price - the number at which net profit hits $0.00
  • → Sensitivity table across 2-3 alternate price points, so you see the real range of outcomes before you commit capital
  • → Flags for FBA Small & Light eligibility or oversize/prep-fee triggers before they wreck your model
  • → Every fee percentage and tier assumption stated out loud - nothing hidden in the math

Questions about this product

What does the Derek skill do?+

Derek turns unit cost, weight and selling price into an exact profit waterfall before you source - an FBA fee and referral fee breakdown, landed cost and margin at your price, and a break-even price with a go/no-go read. Load once into Claude Projects and get a configured FBA profit calculator in every session.

How do I install this skill file?+

Download the .skill package (it contains SKILL.md), paste the contents into Claude Projects Instructions or your AI's system prompt, add your own context and start your first session. Works with Claude, ChatGPT, or any AI chat that accepts system prompts.

Which AI tools does this skill work with?+

Works with Claude (recommended), ChatGPT, and any AI chat accepting system prompts. Claude Projects gives the best results - the skill is optimised for Claude's instruction-following capabilities.

How is this different from using Claude without the Derek skill?+

Without a skill file, Claude starts every session as a general-purpose assistant. With Derek loaded, Claude runs the full fee and margin maths per unit and gives a break-even price and a go/no-go call from the first message - no re-explaining, consistent quality every time.
