Methodology

MarginIndex is an independent research platform focused on e-commerce margins and cost structures.
The goal is clarity — not promotion.

How analyses are created

  • Public data

    Platform fee structures and publicly available documentation.

  • Real scenarios

    Selling models based on realistic pricing, volume, and margin assumptions.

  • Cost modelling

    Operational costs, returns, and fee stacking included in calculations.

  • Break-even logic

    Identifying where selling becomes structurally profitable or unprofitable.

What MarginIndex does not do
