How do I know if my Google Ads are profitable?

Compare actual ROAS to break-even ROAS from your margin, then calculate net ad profit in dollars. Platform revenue ROAS alone is not enough.

What ROAS is profitable?

Any ROAS above your break-even ROAS is profitable. The exact number depends on margin — there is no universal threshold.

Should I scale campaigns at break-even ROAS?

Break-even means zero profit. Scale only when ROAS is above break-even and ad profit is positive, unless you have strategic reasons to accept losses temporarily.

How to Check If Your Ad Campaigns Are Actually Profitable

Revenue ROAS in your ad platform is a starting point — not the final answer. Here is a five-step checklist to know if campaigns make money after product costs and ad spend.

Step 1: Calculate contribution margin

Contribution = (AOV × gross margin%) − fixed costs per order. Without this number, you cannot know if any ROAS is profitable.

Step 2: Find break-even ROAS

Break-even ROAS = AOV ÷ contribution per order

This is your floor. Actual ROAS below this means the campaign loses money.

Step 3: Compare actual ROAS

Pull actual ROAS from the ad platform for the same date range. Ensure conversion value reflects true AOV — especially if you use average order value vs last-click SKU value.

Step 4: Calculate ad profit in dollars

ROAS alone does not show dollar impact. Ad profit = total contribution from conversions minus ad spend. A campaign at 2.5× ROAS on $10,000 spend behaves very differently than the same ROAS on $500 spend.

Use the Ad Profit Calculator for revenue, contribution, and net profit in one view.

Step 5: Set scaling rules

Below break-even ROAS → reduce spend or fix funnel/margin
At break-even → optimize before scaling
Above break-even with positive ad profit → test incremental budget in 10–20% steps
Re-check after each scale — CPA often rises with volume
