Check markup against marketplace fee data
Markup and keystone targets are set before marketplace fees, but the final listing decision depends on fee drag. Use the Fee Index for same-input marketplace rows, Fee Changes for recent policy updates, and Seller Reports for dated summaries before turning a pricing rule into a listing plan.
After the source check, use the markup result as the starting point for a platform calculator or break-even pass.
Turn this result into a listing decision
Use the tool result as a starting point, then test payout, break-even price, shipping, and marketplace fit before you publish the listing.
Markup versus margin
Markup compares profit to cost. Margin compares profit to sale price. A $20 item listed for $50 has a 150% markup but a 60% gross margin before marketplace fees.
Resellers use markup for sourcing rules because it starts with buy cost. Margin is better after fees because it shows how much of the sale price remains as profit.
