Amazon FBA pricing mistakes usually come from underestimating unit-level costs.
One mistake is only subtracting product cost. FBA fulfillment fees, referral fees, inbound shipping, prep costs, returns, and storage can all affect margin.
Another mistake is using the same target price after fees change. If fulfillment or referral fees rise, the old price may no longer leave enough profit.
A third mistake is scaling ads before checking profit per unit. More sales can create less cash if ad cost pushes unit profit too low.
Use the Amazon FBA Profit Calculator at /tools/amazon-fba-profit-calculator before changing price or ad spend. Then compare with the Marketplace Profit Calculator at /tools/marketplace-profit-calculator and Product Pricing Calculator at /tools/product-pricing-calculator.
