Both figures come from the same calculation: order revenue minus commission on whichever base the platform actually uses, minus per-order and payment fees, minus the consumption tax sitting inside your price where that applies, minus your product cost and shipping. No midpoints are invented — where a marketplace publishes a band, you see the band.
Referral fee on item price plus delivery and gift wrap. Two tier shapes are both in use: flat bands (apparel, beauty, baby, grocery) and marginal "portion of" tiers (jewelry, watches, furniture, electronics accessories).

Referral fee on the total sales price including shipping and handling. No monthly fee, payments included. WFS fulfilment prices on weight alone with additive modifiers.
On a $29.99 product costing $8.00 with $5.00 shipping, Amazon nets about $12.49 per unit versus $12.49 on Walmart Marketplace — a gap of roughly $0.00. That ordering can flip with a different price or category, so run your own numbers before committing.
