How to find the products losing you money

    A practical method you can run manually in a spreadsheet, or let Pythago run continuously.
    1. 1

      Get your true cost per unit

      Supplier price, inbound shipping, outbound shipping, packaging. Not an estimate — the actual figures for the last 30 days.

    2. 2

      Add transaction fees

      Payment processor percentage plus the fixed fee per order. On a €30 product this is often more than people assume.

    3. 3

      Account for returns

      A 6% return rate on a thin-margin product can erase the margin entirely, because you refund the revenue but rarely recover the cost.

    4. 4

      Pull ad spend per product

      This is where it breaks down manually. Standard Shopping gives it to you. Performance Max does not.

    5. 5

      Compare against break-even ROAS per product

      Not one blanket target — each product's own number, from its own margin.

    What you'll find

    Typically two or three products carrying the account, and a tail of products that convert but contribute nothing.

    Or skip the spreadsheet

    Pythago does steps 1–5 continuously and flags products below break-even, per campaign and per product.
