How to use this calculator

  • Enter your Google Ads spend.
  • Enter revenue attributed to the campaign.
  • Add your target ROAS and gross margin for a stronger profitability check.
  • Review the revenue gap and health score.

What the result means

ROAS shows how much revenue is generated for each dollar spent on ads. Higher ROAS indicates stronger media efficiency, but profitability still depends on margin and operating costs.

ROAS = Revenue ÷ Ad Spend

A campaign can have strong ROAS but weak ROI if margins are low or fulfillment costs are high.

Example calculation

If you spend $1,000 and generate $5,500 in attributed revenue, ROAS is 5.5x or 550%.

Tips for better results

  • Segment campaigns by product margin.
  • Use target ROAS bidding only after conversion tracking is reliable.
  • Raise average order value to improve ROAS.
  • Check ROI if your product margin is low.

FAQ

What is a good ROAS for Google Ads?

A ROAS above 4x is often considered good, but the right target depends on margin, customer lifetime value, and acquisition cost.

How much ROAS do I need to be profitable?

Break-even ROAS is roughly 1 divided by gross margin. A 50% margin usually requires at least 2x ROAS to break even before overhead.

Why is my Google Ads ROAS lower than expected?

Low ROAS can come from weak targeting, low conversion rate, poor offer fit, or revenue tracking issues.

How can I improve Google Ads ROAS?

Improve keyword intent, landing page conversion, product margin, average order value, and negative keyword coverage.

Is ROAS more important than ROI for Google Ads?

ROAS is useful for ad efficiency, while ROI is better for final profitability because it includes non-ad costs.
