What you receive

  • Current contribution margin per unit and per month
  • Margin and margin percent at each candidate price
  • Break-even units and required volume change
  • Profit change at today's volume
  • Below-cost, thin-margin, and price-parity flags

Who it is for

Sellers, agencies, and agents pressure-testing a discount or price increase before changing it in Seller Central.

Delivery: usually a structured result, workbook, or ZIP depending on the tool.

How it stays safe

Friday does arithmetic on the costs and volume you supply. It does not read your seller account, fetch live fee schedules or competitor prices, forecast demand, or change any price. It does not publish listings or tell you what to charge, and it is not accounting, tax, or pricing-compliance advice.
