Shows the ROAS you need to break even.
ROAS = revenue ÷ ad spend. It measures revenue, not profit: a 4x ROAS can still lose money once product, shipping and other costs are taken out. ROI, by contrast, compares profit to the total investment.

About this tool
Return on ad spend measures revenue generated per unit of advertising cost: ROAS = revenue ÷ ad spend. It's usually written as a ratio (4x or 4:1) or a percentage (400%).
Example: $1,000 of revenue from $250 of ad spend is a ROAS of 4x, or 400% — every $1 of ads brought in $4 of sales. If your profit margin is 25%, you need a ROAS of 100 ÷ 25 = 4x just to cover the ad cost, so this campaign only breaks even.
ROAS is not ROI. ROAS uses revenue and only counts ad spend, while ROI uses profit and counts all costs — products, shipping, fees, staff. A campaign with a healthy-looking ROAS can still lose money if margins are thin, which is why the break-even ROAS figure is useful. Attribution also matters: platforms may count the same sale differently.
