Items priced under $15 are where Amazon's fee structure gets meanest: the $0.30 minimum referral fee can take 15% or more of a $2 sale, and a flat small-standard fulfillment fee near $3.91 eats a huge slice of a $5 gadget. Pricing cheap products needs the calculator more, not less.
| Price | Category (rate) | Raw math | Referral billed | Effective rate |
|---|---|---|---|---|
| $1.99 | Home (15%) | 15% x $1.99 = $0.2985 | $0.30 (floor) | 15.1% |
| $2.99 | Home (15%) | 15% x $2.99 = $0.4485 | $0.45 | 15.0% |
| $9.99 | Beauty (8% at ≤$10) | 8% x $9.99 = $0.7992 | $0.80 | 8.0% |
| $12.00 | Grocery (8% at ≤$15, no floor) | 8% x $12.00 | $0.96 | 8.0% |
The calculator enforces the $0.30 floor, the beauty/grocery 8% thresholds and the correct size row automatically:
Amazon bills the greater of your category rate times price or $0.30. On a $1.99 Home item, 15% computes to $0.2985, so the $0.30 floor applies. On a $2.99 item, 15% computes to $0.45, so the floor does nothing. Grocery, video games, gift cards, books/media and fine art have no minimum fee at all.
Beauty and Personal Care plus Baby Products pay 8% at or below $10 and jump to 15% above $10. Grocery and Gourmet Food holds 8% at or below $15. So a $9.99 beauty item pays $0.80, and a $12 grocery item pays $0.96 — check the price tier before crossing those thresholds, because the rate flips on the whole price.
Small-standard fulfillment at 12 oz and price tier 1 is $3.78 plus a 3.5% surcharge ($0.13), about $3.91 per unit, before referral. On a $4.99 beauty item you also pay a $0.40 referral plus roughly $3.01 large-standard fulfillment for a 4 x 3 x 1 in, 4 oz parcel — about $3.41 in Amazon fees against a product cost near $2. Cheap items only work with low landed cost, tight packaging, or bundles that lift the price.
Yes. For large-standard items FBA bills dimensional weight: the greater of actual unit weight or length times width times height divided by 139. A genuinely small gadget shipped in a bloated mailer can clear the 1 lb weight limit or the 15 x 12 x 0.75 in dimension limits and jump from $3.78 small-standard to roughly $5-plus large-standard fees. Measure the package, not the product.
