Formula

Core Formula

\text{Net} = \text{Price} - \text{COGS} - \text{Referral} - \text{FBA} - \text{Inbound} - \text{Ads} - \text{Storage}

How it works: Referral is a percent of selling price. FBA fulfillment is the per-unit pick and pack fee from the size tier. Inbound covers shipping inventory to Amazon. Storage is optional per unit for planning.

Worked Example

Selling price $39.99, COGS $12, referral 15%, FBA fulfillment $5.50, inbound $0.50, ads $3, storage $0:

1Step 1: Referral = 39.99 x 0.15 = $6.00

2Step 2: Total costs = 12 + 6 + 5.5 + 0.5 + 3 = $27.00

3Step 3: Net = 39.99 - 27 = $12.99

4Step 4: Margin = 12.99 / 39.99 = 32.5%

Modeling Amazon FBA Unit Economics

Fulfillment by Amazon moves storage, picking, packing, and customer service into your cost structure alongside referral fees. Sellers who only subtract COGS from price often miss the full picture. This calculator separates referral (a percent of price), fulfillment (a per-unit fee from size tier), inbound shipping to Amazon, advertising spend, and optional storage so you can compare SKUs on a like-for-like basis.\n\nUse it as a planning tool before you reorder inventory or change price. Pair it with a returns assumption and your actual fee reports when you need an end-of-month reconciliation.

Referral fees depend on category and are a percent of the customer price.
Fulfillment fees depend on size tier and shipping weight, not a flat percent.
Inbound and storage costs matter most for heavy or slow-moving products.

Always cross-check fees in Seller Central before final pricing decisions.

Frequently Asked Questions

Where do I find FBA fulfillment fees?

Amazon publishes fee tables by size tier and shipping weight. Use the estimate in Seller Central for your SKU or the official rate card for your marketplace.

Does this include returns?

No. Treat returns, refunds, and remittance as separate adjustments. This tool is a simple per-unit snapshot.

How is this different from the general e-commerce profit calculator?

This page focuses on FBA line items (referral, fulfillment, inbound, storage) so sellers can model one SKU without picking another platform.
