FBA Profit Calculator

Most sellers know their price and their unit cost and assume the gap is profit. It is not. Amazon takes a referral fee, a fulfillment fee, and storage, dimensional weight can blow up the shipping line on a light-but-bulky product, and there are cost lines sellers forget entirely. This skill builds the full stack and returns the real number, and settles the FBA versus FBM question with cost evidence.

When to use this

• Evaluating whether a product to source can actually be profitable.
• A product sells well but the bank balance does not grow and nobody knows why.
• Comparing FBA versus FBM, or comparing two product sizes or price points.
• Setting a price from a target margin instead of guessing.
• A product's fees feel high and the seller does not know which line to blame.
• Comparing two package designs by fulfillment cost.
