Amazon FBA Profitability Calculator

$99

The Amazon FBA Profitability Calculator computes the full per-unit P&L for any FBA SKU: landed cost, FBA fulfillment fee, referral fee, storage fee, ad spend, and payment fee, down to net contribution. The Scorecard compares your catalog by margin tier with a recommended action, and the single-SKU Calculator runs the same math pre-launch for a GO/NO-GO call.

How it works

Every fee Amazon charges gets its own line, so nothing gets buried in a single “fees” number.

  1. Inputs: Business constants: payment fee %, ad spend % (a TACoS proxy), and your minimum margin target
  2. Fees: The lookup source: 22 FBA size-tier fees, 26 referral fee categories, and storage rates
  3. SKUs: Your product master: category, size tier, dimensions, weight, costs, and monthly units
  4. Calculator: A single-SKU scenario tool for pre-launch “should I list this?” decisions
  5. Scorecard: The catalog table: landed cost, FBA fulfillment, referral, storage, and ad spend rolled up to net per unit, monthly contribution, and tier
  6. SKU Dashboard: Pick a SKU for the full P&L waterfall and monthly contribution
  7. Dashboard: The catalog view: total contribution, tier distribution, top and bottom SKUs, and performance by category

Steps to use it

  1. Set payment fee %, ad spend %, and minimum margin target on Inputs
  2. Review Fees and update values as Amazon revises its schedule
  3. Build your catalog on SKUs: category, size tier, dimensions, weight, costs, monthly units
  4. Use Calculator for a pre-launch GO/NO-GO read on any hypothetical product
  5. Review Scorecard for per-SKU net contribution and tier
  6. Open SKU Dashboard for the full waterfall on any SKU, then Dashboard for the catalog view

Margin tiers are built in: A at 30% net margin or above, B from 20% to 30%, C from 10% to 20%, D below 10% or negative. Recommended action follows tier: keep and lean in at A, keep and optimize cost at B, reconsider sourcing or price at C, and kill or delist at D.
