FBA vs FBM Calculator: Which Fulfillment Method Protects More Profit?

FBA and FBM can produce very different profit outcomes. FBA may offer convenience and conversion benefits, while FBM may give more control over shipping and handling. The better choice depends on cost, speed, category, size, labor, and operational capacity.

An FBA vs FBM calculator compares the same product under two fulfillment models. This helps sellers decide whether Amazon fulfillment or merchant fulfillment is stronger for a specific product.

FBA costs to include

FBA math should include referral fee, FBA fulfillment fee, inbound shipping, prep, storage allowance, returns, and PPC if advertising is part of the strategy.

FBM costs to include

FBM math should include postage, packaging, handling labor, customer service time, shipping software, returns, and any risk from slower delivery or lower conversion.

Compare with real numbers

Start by modeling the FBA version in the Amazon FBA Profit Calculator. Then compare it to your own FBM shipping and labor assumptions. The best method is the one that protects profit and fits your operations.
