Practical guide

How to Use the Amazon FBA vs FBM Calculator

An Amazon FBA vs FBM calculator is only as reliable as its fee and labor inputs. Pull FBA fees from current reports and time the real FBM workflow.

Keep demand assumptions equal

Start with the same order volume to isolate fulfillment economics. Model a separate scenario if Prime eligibility or delivery speed changes conversion.

Include hidden fulfillment costs

FBA has inbound and storage costs; FBM has packaging, labor, carrier, software and capacity costs. Omitting either side biases the result.

Model returns consistently

Refunded revenue and processing costs can differ by method. Use recent product-level return rates where available.
