Calculate Amazon per-unit margin, break-even or target-margin price, affordable ad spend, and period P&L waterfalls. Use for ASIN profitability, unit economics, contribution or channel margin, landed cost, COGS, TACoS, fee and return impact, settlement reconciliation, or period-over-period margin movement. Excludes live repricing, return-reason diagnosis, and ad campaign reporting.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Amazon Profitability Two calculations that people routinely conflate. Work out which one is being asked for before doing anything else. | | **Per-unit cascade** | **Period P&L** | | --- | --- | --- | | Question | Should I sell this, at what price? | What did the business actually make? | | Scope | One hypothetical unit | A brand or account over a period | | Script | `scripts/margin.py` | `scripts/pnl.py` | | Reference | `references/formulas.md` | `references/period-pnl.md` | | Has | Break-even and target-price solvers | Cancellations, claims, chargebacks, reimbursements, overheads | | Lacks | Everything in the column to the right | Any notion of price solving | The period model is **not** the per-unit model summed up. It has revenue lines the per-unit model has no concept of, and the per-unit model solves for prices the period model cannot. Signals: "this ASIN", "should I price at", "can I afford" → per-unit. "last quarter", "our margin", "why did it drop", "net margin" → period. If genuinely ambiguous, ask. Running the wrong one produces a confident answer to a question nobody asked. **This skill is read-only.** It reads fees, listings, reports and costs, and computes. …

How to install
mdr add kuudoai/skills/amazon-profitability-calculator@sha256:698f695e3eb70873The line at the top of this page pins the label v0.2.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
