保本 ROAS 计算器
输入毛利率,立即得到广告不亏钱所需的最低 ROAS(保本 ROAS = 1 ÷ 毛利率)。再输入目标利润率,可反推达成利润目标所需的目标 ROAS。保本 ROAS 取决于你自己的单位经济模型而非平台基准,是评判任何 ROAS 数字好坏之前必须先知道的数字,适合电商和 DTC 广告主在制定出价策略前使用。
主要用途
This calculator tells you the minimum ROAS a campaign must hit just to avoid losing money, derived from your profit margin. Enter your gross margin percentage (or your cost and price) and it returns the break-even ROAS — the revenue-per-dollar-of-spend figure below which every sale erodes profit. Because break-even ROAS is simply the inverse of margin, a 25% margin needs a 4.0 ROAS while a 50% margin breaks even at 2.0, a relationship that surprises many advertisers chasing a single universal target. Teams use it to set realistic bid and budget targets, judge whether a channel can ever be profitable at current pricing, and brief agencies with a number grounded in unit economics rather than a guess.

新手提示
- Use margin after cost of goods and variable fulfilment, not gross revenue, or your floor will be too low.
- Break-even is the floor, not the goal — set your actual target above it to fund overhead and growth.
- Recheck the number whenever pricing, discounts, or shipping costs change your real margin.
