Amazon FBA Profitability Calculator

How to calculate Amazon FBA profitability calculator?

This calculator estimates per-unit profit by subtracting product cost, Amazon fees, referral fees, and advertising spend from the selling price.

Key formula: profit = selling_price - (product_cost + fba_fulfillment_fees + referral_fee + advertising_cost)

Using the Amazon FBA profitability calculator calculator: an example

Example values: Selling Price $29.99, Product Cost $8.00, FBA Fees $4.50, Referral Fee 15%, ACoS 10%.

Step-by-step calculation:

• Referral fee = $29.99 × 15% ≈ $4.50
• Advertising cost (ACoS) = $29.99 × 10% ≈ $3.00
• Total costs = $8.00 (product) + $4.50 (FBA) + $4.50 (referral) + $3.00 (ads) = $20.00
• Net profit = $29.99 − $20.00 = $9.99 (profit margin ≈ 33.3%)

Frequently Asked Questions

Does the referral fee apply to discounted or promotional prices?

Yes. Amazon’s referral fee is typically calculated on the final sale price after discounts and promotions unless a specific exemption applies.

How is ACoS reflected in this calculator?

ACoS represents advertising spend as a percentage of sales; the calculator estimates per-unit ad cost as Selling Price × ACoS% to approximate ad expense.

Are long-term storage fees included in FBA fulfillment fees?

Not automatically. Add any per-unit storage or long-term storage charges into the FBA Fulfillment Fees field so they are counted in total costs.

Can I use this for bundles or multi-packs?

Yes. Use the bundle’s total selling price and combined product cost; note that Amazon fees may vary with package size and weight so update FBA fees accordingly.
