How it works
Methodology & formulas
This calculator is transparent by design. Review the steps and formulas so you can trust the estimate and adjust assumptions when your dashboard differs.
Calculation steps
- 1FbaCostPerUnit = pickPack + weightHandling + inbound + packagingPerUnit.
- 2FbmCostPerUnit = fbmShippingLabel + fbmPickAndPack + fbmPackaging.
- 3CostDifferencePerUnit = fbmCost − fbaCost. Positive means FBA cheaper.
- 4Total difference = |costDifference| × quantity.
- 5Weight tier note derived from item weight ounces and size tier selection for educational guidance.
Formulas
- FBA per unit = pick&pack + weight + inbound + packaging
- FBM per unit = carrier label + pick labor + packaging
- Difference = FBM per unit − FBA per unit
- Total difference = difference × quantity
Important assumptions
- FBA per-unit = fbaPickAndPack + fbaWeightHandling + inboundToFbaPerUnit + packagingPerUnit.
- FBM per-unit = fbmShippingLabel + fbmPickAndPack + fbmPackaging when quantity 1, averages same per unit for batch.
- Size tier affects FBA rate card but input fees already reflect tier; tier field provides context only, not auto-fee lookup.
- Dimensional weight noted in weight insight but not auto-calculated — user should include dimensional impact in weight handling fee input.
- Cheaper method is lower per-unit total.

Worked example
8oz small standard item — FBA vs FBM
Small standard 8oz, FBA pick $2.50 weight $1.50 inbound $0.50 packaging $0.40, FBM label $4.00 pick $1.00 packaging $0.60, quantity 1.
FBA total $2.50+1.50+0.50+0.40=$4.90 per unit. FBM total $4+1+0.60=$5.60 per unit. FBA saves $0.70 per unit. For 100 units batch, total savings $70 choosing FBA. Light small standard favors FBA due to low weight handling and shared inbound freight.
