How Do You Use a Minimum ROAS Bid Strategy?

Minimum ROAS is the old name for what Meta now calls ROAS goal. You set an average return on ad spend and Meta bids to keep your weekly average near it. It fits when you track purchase value and know the return you need to stay profitable. It does not fit if you cannot track conversion values, have too few weekly conversions, or care more about spending the full budget.

What does a ROAS goal do?

Meta says to select maximize value of conversions as the ad set performance goal first. If you use Advantage+ campaign budget, pick ROAS goal as the campaign bid strategy, then enter the value in each ad set. Meta says the system adjusts bids to maximize conversion value while keeping the weekly average ROAS near your goal, that day-to-day ROAS fluctuates, and that your actual weekly average may vary from the goal.

Meta renamed minimum ROAS to ROAS goal and says the rollout is gradual, so your account may show either label.

What do you need before you use it?

• Tracking. Meta says you need a working Meta pixel or Meta SDK tracking conversion events.
• Eligibility. You must meet the eligibility requirements for the maximize value of conversions performance goal.
• Enough volume. Meta says it works best with at least 50 to 100 weekly conversions in the ad set.
• A baseline. With no history, Meta suggests running highest value for at least 2 weeks and using the resulting ROAS as a starting goal.
• Time. If you deliver to people on iOS 14.5 or later devices, Meta says the ad set should be scheduled for at least 3 full days.

How do you read the goal number?

Meta expresses the goal as a number between 0.001 and 1000.00. A value of 1.00 means $100 spent returns about $100 in recorded purchase value. That covers advertising spend only; it does not cover product, shipping or other costs. At a 40% margin after costs, business break-even is 2.50, not 1.00. A value of 1.15 means about $115 per $100. Meta says to set the goal from the return your business needs to be profitable, and to base it on results within your attribution setting. The break-even ROAS page shows how to find that number from your margin.

What do you change when delivery or return drifts?

Meta describes two situations. Bid constrained means a significant part of the weekly budget is unspent. Budget constrained means it is fully spent and you want more.

What you see	What Meta suggests as a starting point
Bid constrained	Lower the ROAS goal by 5 to 10 percent
Underspending, with weekly ROAS below target	Consolidate ad sets to reach 50 to 100 or more weekly conversions
Fully spent, ROAS good	Raise the budget, and adjust the target after 1 week
Fully spent, ROAS well below target	Raise the goal by 5 to 10 percent
A bigger budget did not bring more value	Lower the goal, update creatives or expand the audience

The direction is the opposite of a cost goal, because a higher ROAS goal is a tighter limit. Meta says to wait at least 7 days after any adjustment and to judge weekly averages.

ROAS goal or highest value?

Meta says highest value maximizes conversion value while prioritizing spending your full budget, with no specific return target. ROAS goal maximizes value near your target and may spend less than the full budget in a competitive market. Choose ROAS goal if holding a return matters most, and highest value if spending the full budget matters most.

FAQ

Is minimum ROAS the same as ROAS goal?

By Meta’s renaming table, yes: minimum ROAS became ROAS goal. Meta says the change is rolling out gradually, so older labels may still appear in some accounts. Highest value and bid cap kept their names.

Why is my ROAS goal not spending my budget?

Meta says a ROAS goal may spend less than your full budget when the market is competitive, to protect your target. If a significant part of the weekly budget is left, Meta suggests lowering the goal by 5 to 10 percent as a starting point.

Does a ROAS goal guarantee my return?

No. Meta says the goal is an input to the ad auction and that adherence is not guaranteed. Your actual weekly average ROAS may vary from the goal, and Meta says more conversions give more accurate results.
