ROAS (Return on Ad Spend) is total revenue divided by total ad spend. A ROAS of 4x means you earned $4 for every $1 spent on advertising. It is the primary metric for measuring ad campaign efficiency.

A good ROAS depends on your profit margins. E-commerce businesses with 30–50% margins typically need a ROAS of 3–5x to be profitable. Use the break-even ROAS field with your actual margin to find your exact target.

What is break-even ROAS?

Break-even ROAS is the minimum ROAS you need to cover product costs. It equals 1 divided by your gross margin percentage. For example, a 25% margin requires a break-even ROAS of 4x (1 / 0.25 = 4).

How does ROAS differ from ROI?

ROAS measures revenue relative to ad spend only, while ROI accounts for all costs including product cost, fulfillment, and overhead. ROAS is a quick efficiency gauge; ROI tells you true profitability.

How do I improve my ROAS?

Improve ad targeting to reach higher-intent audiences, optimize landing page conversion rate, test ad creatives, increase average order value, and pause underperforming ad sets. Raising prices also improves ROAS without changing spend.

Can I use this for non-e-commerce campaigns?

Yes. Enter any revenue tied to your ads — lead value, subscription MRR, or estimated LTV. The break-even margin field is optional, so you can calculate basic ROAS for any campaign type.
