Scorecard

Will this SKU clear the Small Bulky cut?

One boring input card. The right side tells you, before launch dollars move, whether the box lands inside Amazon’s Small Bulky tier — the one whose 8–12% FBA + 8–14% FBT fee band is friendly to a single-SKU line.

Numbers from the brief, pass/fail cutoffs already in. Adjust as the fee schedule moves; the structure stays.

Worked examples

Five boring SKUs, ranked side-by-side.

The form above grades one input. This table grades five previously-scored SKUs on the four underwriting axes simultaneously — weight, size tier, fee band, repeat signal — with a weighted total that reconciles with what the form would produce for the same line. Each row links the math out to fee math and the CPM pad so the scorecard is the entry point of the underwriting funnel, not a calculator in isolation. Full per-axis methodology is in the notes below the table.

MethodologyHow each axis is scored▾

(weight × 0.20) + (size × 0.30) + (fee × 0.30) + (repeat × 0.20), clamped 0–100. Weights shown above so the ranking is honest.

  • Weight axisweight 0.20

    0–25 → 0 floor; 50 at 0.8 kg; 100 at ≥ 1.5 kg (capped at the 9 kg Amazon parcel ceiling above).

  • Size tier axisweight 0.30

    FBA Small Bulky = 100; Heavy Bulky = 60; Standard = 40; Oversize = 10. (Different knee than the form's pass/fail — the form reports pass/fail, the table reports 0–100.)

  • Fee band axisweight 0.30

    Amazon referral + FBA vs TikTok FBT commission. 10–14% sweet spot = 100; 8–17% friendly band ramps 50→100; outside 8–17% decays 50→0.

  • Repeat-purchase axisweight 0.20

    Consumable adjacency + replacement cadence. High = 100; Medium = 60; Low = 20.
