# Run an Amazon Profitability Calculator on Live Fees

An Amazon profitability calculator that computes per-unit margin, the safe break-even and target-margin price, affordable ad spend, and a period P&L waterfall from Amazon's own fee estimates at each candidate price rather than from a rate card. The Profitability Calculator Skill asks for your cost of goods rather than guessing it and names where every fee came from.

Fees sourced, never invented

Is this the right Skill?

## Use it for a clear operating job.

Best for

*   Should I sell this ASIN, and at what price
*   Affordable ad spend at a target margin
*   Quarter-over-quarter margin movement by checkpoint

Use another path when

Live repricing, return-reason diagnosis, or ad campaign reporting; the per-unit floor is handed to repricing work as an input.

Starter prompt

## Start with the task, then add your scope.

Copy this into a connected client and replace the account, date, ASIN, or threshold details with yours.

```text
B08XYZ1234 sells for $29.99 in the US. Landed cost is $8, inbound freight about a dollar a unit, and I spend roughly $2 a unit on Sponsored Products. Am I making money on it, and what is the lowest price I could go to?
```

The Skill will request any required context or approval before guarded actions.

The outcome

## A defined result, not a generic answer.

Summary metrics, a fee waterfall, and an assumptions list naming where each number came from, with the margin denominator stated and any loss zones named.

Inputs

*   ASIN or SKU and marketplace
*   COGS, inbound freight, VAT rate, other per-unit costs, target margin
*   A prior period, for margin movement

Outputs

*   Break-even safe floor and target-margin price
*   Fee waterfall with the denominator named
*   Period P&L checkpoints and their movement

Workflow

## The playbook your agent follows.

1.  01
    
    ### Confirm context
    
    Confirm the marketplace and, where there is more than one, the account, identity, and Ads profile, presenting the options rather than picking silently.
    
2.  02
    
    ### Probe Amazon's side
    
    Batch fee estimates across roughly 0.5x to 2x the current price, and say which surcharges the estimate excludes.
    
3.  03
    
    ### Collect the seller's side
    
    Ask where COGS lives before asking for the number, then take inbound freight, VAT rate, other per-unit costs, and target margin.
    
4.  04
    
    ### Compute the cascade
    
    Recompute every fee at each candidate price and report the safe floor, naming any loss zone a whole-price band creates.
    
5.  05
    
    ### Report with assumptions
    
    Summary metrics, waterfall, then an assumptions list naming where each number came from and which denominator the margin uses.
    

Guardrails

## What keeps the workflow dependable.

No fee number is invented: a rate not in the tables, the API, or the seller's inputs is left out with a note

Without the MCPs it runs in manual mode on seller-supplied fees and labels the output as such

Estimate and actual stay distinct: live mode is Amazon's estimate of its fees, settlement is what was charged
