The Profitability Illusion

Many marketplace sellers see a gap between cost price and selling price and assume that gap equals profit. In reality, for most sellers, the "visible margin" can be 40-60% higher than actual profit after accounting for all cost layers.

The Complete Cost Stack

Every marketplace sale carries: product cost, platform commission (8-30% depending on category), shipping cost, packaging materials, return processing, advertising spend, and payment processing fees.

Building Your Profit Simulator

A profit simulator calculates net margin for any combination of selling price and cost inputs. Working backwards from a target margin is more strategic than cost-plus pricing. Define your required minimum margin, input all costs, and let the simulator tell you your floor price.

Portfolio Profitability Management

ABC analysis combined with margin data reveals which products deserve your attention. High-revenue, high-margin products are your stars. Low-revenue products need lifecycle management decisions. MetrivoAI's profitability module provides this portfolio view automatically.
