Start with Break-even Price to make sure your price covers costs and percent-based fees. Then use Profit Margin to verify net profit after shipping and ads. If you want to set a price based on a target margin, use Product Pricing. For ad planning, use Ad CPO to find your maximum ad spend per order. If you sell on Amazon FBA, use Amazon FBA Fee to estimate referral + fulfillment fees and sanity-check profit.
