ROAS (Return on Ad Spend)

ROAS measures the revenue generated for every dollar spent on advertising, calculated as revenue divided by ad spend.

A ROAS of 4x means every $1 spent on ads generated $4 in revenue. ROAS is useful for comparing campaign efficiency, but it doesn’t account for profit margin — a 4x ROAS on a low-margin product can be less profitable than a 2x ROAS on a high-margin one. Because of this, ZAVYANS reports ROAS alongside margin-aware metrics rather than treating it as the only number that matters.

ROAS in practice

If a Meta Ads campaign costs $1,000 and brings in $4,500 in sales, its ROAS is 4.5x. If the products have a 30% profit margin, those sales produce $1,350 of gross profit, so after the $1,000 ad cost the campaign made $350.

Common questions about ROAS

How do you calculate ROAS?

Divide the revenue from ads by what you spent on those ads. For example, 400,000 in revenue from 100,000 in ad spend is a ROAS of 4, often written 4x or 400%.

What is a good ROAS?

It depends on your margins. Break-even ROAS is 1 divided by your profit margin, so a business with a 25% margin needs a ROAS of at least 4 just to cover ad costs.

What's the difference between ROAS and ROI?

ROAS only compares ad revenue with ad spend. ROI compares profit with all costs, including product costs, fees and staff time.

Why does my ROAS look different in Meta and Google Analytics?

Each tool uses its own attribution rules and time windows, and ad platforms often count sales they influenced even when another channel got the final click. Compare trends within one tool rather than expecting the numbers to match exactly.
