ROAS, or Return on Ad Spend, is one of the key metrics used by e-commerce to measure the effectiveness of their advertising campaigns. Understanding what it is and how to calculate it is not only a fundamental aspect of managing an online store but also an extremely valuable tool in the decision-making process.

What is ROAS?

ROAS is an indicator that allows you to assess how much revenue is generated by each spent dollar (or other currency) on advertising. It’s a key metric that evaluates whether the investment in advertising is yielding the expected results. Without using this indicator, running an online store is complicated and risky.

How to Calculate ROAS?

Calculating ROAS is relatively simple. You just divide the revenue from advertising by the advertising costs. This means that if you spend 1000 dollars on advertising and generate 5000 dollars in revenue, your ROAS is 5. This means that for every dollar spent on advertising, you earn 5 dollars.
