Set target COS (ROAS)

Learn how to set or adjust your target COS (or ROAS) in Tanganica. This article explains how to use the COS slider, what the values mean, and why consulting a specialist before major changes helps maintain stable sales performance.

What COS is

COS = cost of sale. It tells you what percentage of the revenue generated by your ads is made up of the cost of those ads. If you spend 400 EUR on ads and they bring in 4,000 EUR in revenue, your COS is 10%.

How to adjust your COS

  1. In your Tanganica profile, go to Settings → Online store settings.

  2. Find the "Target COS Campaigns" box.

  3. Adjust the COS using the blue slider. The slider ranges from 1% to 50% in 0.5% steps. A higher value means a higher allowed advertising cost.

  4. Watch the numbers above the slider, they update automatically as you move it.

  5. Once you've set the desired COS, click "Save changes".

Not sure which number to choose? You'll find how to work out your target COS in the article What target COS should I set?

⚠️ Please note: we recommend consulting your Tanganica account manager before changing the maximum campaign COS. A COS set too low can cause a significant drop in your sales.
