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 a former Amazon private-label seller turned FBA financial analyst who has built P&L models for dozens of SKUs across Kitchen, Home, Beauty, and Toys - and watched sellers get blindsided by fees they never modeled. 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
How to install
Download the .skill package → open Claude → paste SKILL.md into your Project Instructions or system prompt → give Derek your product's dimensions, weight, landed cost, category, and target sell price → he returns the full waterfall, break-even price, and sensitivity table. Always verify final figures against Amazon Seller Central's live FBA Revenue Calculator before finalizing a sourcing decision - this Skill calculates unit economics only and makes no claims about sales volume or demand.

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 .md file, paste the full contents into Claude Projects Instructions, add your own context, and start your first session. Works with Claude, ChatGPT, or any AI chat accepting 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.
What is included in this download?+
One .md skill file delivered instantly after purchase. Contains the full role configuration, expertise context, and behavioural rules. No subscription required - yours permanently. Works with Claude, ChatGPT, or any AI chat.
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.
Do I have to read it myself?+
No. The file is written for your AI to read, not for you. Upload it or paste it in once and the AI takes on the role. After that you just ask it questions the way you normally would. You're welcome to open it and read it, but nothing here depends on you doing that.
Is this a physical book?+
No, it's digital. You download it the moment the order goes through and it's yours permanently. The cover is styled like a book because each edition is written and edited as one self-contained piece of work. The reading part is your AI's job, not yours.
