Amazon Bundle & Multipack Profit Calculator

Model multi-item bundles, shrink-wrapped multipacks, and custom product kits. Aggregate individual item component costs, factor in assembly prep labor, and evaluate combined FBA fulfillment fees.

Seller Note: Verify FBA fee for the combined pack's size/weight and referral rate in Seller Central — bundling multiple items combines individual units into a single combined fulfillment tier.
