About

RoasFloor helps ecommerce sellers and media buyers estimate the break-even ROAS and maximum acquisition cost a product can support before spending on ads. Enter a selling price and cost assumptions, then compare and share a calculation through a URL.Free public calculators cover break-even ROAS, target ROAS, CPA, landed cost, import tariffs, dropshipping profit, MER, blended ROAS and TikTok Shop fees. They work without signup. An optional Pro workspace saves SKU scenarios ($19/month or $190/year).A hypothetical $60 order with $24 product cost, $3 inbound logistics and $3 assumed payment fees leaves $30 for ads: 2.0x break-even ROAS. Increase only logistics to $9 and it leaves $24: 2.5x. This example excludes duties, returns, overhead, platform fees and other delivery costs; it is not a customer result or a tariff quote.I built RoasFloor to make the cost assumptions behind an advertising target easier to inspect and share. The site explains its formulas and assumptions. It is a pre-spend planning tool and does not sync ad accounts or orders.
