When to Use This Calculator
Use this calculator to evaluate your Google Ads campaign ROI — whether you are running Search, Shopping, Display, or Performance Max campaigns. It is particularly valuable when deciding whether to increase your daily budget, comparing performance across campaign types, or preparing a monthly performance report. If you use Target ROAS bidding in Google Ads, compare your actual ROAS here against your target to see if the algorithm is hitting its goal.
How to Read Your Results
A Google Ads ROAS of 5x means each dollar of ad spend generated five dollars in tracked revenue. Keep in mind that Google's default attribution uses last-click, which may over-credit Search campaigns and under-credit Display. If your ROAS looks surprisingly high, check whether you are double-counting revenue from users who would have purchased organically. For Shopping campaigns, subtract COGS from revenue before celebrating a high ROAS — a 10x ROAS on a 5% margin product is still barely profitable.
Google Ads Benchmarks by Campaign Type
ROAS varies significantly by campaign type. Compare your performance:
| Campaign Type | Average ROAS | Good ROAS | Notes |
|---|---|---|---|
| Search | 2-4× | 4×+ | High intent, users actively searching |
| Shopping | 4-8× | 8×+ | Product listings, best for e-commerce |
| Display | 1-2× | 2×+ | Brand awareness, lower direct ROAS |
| Video/YouTube | 1.5-3× | 3×+ | Brand storytelling, mid-funnel |
| Performance Max | 3-5× | 5×+ | AI-optimized across all channels |
Shopping campaigns typically have the highest ROAS due to high purchase intent. Data based on Google Ads industry reports (2023-2024).
Google Ads ROAS Formula
Google Ads ROAS = Conversion Value ÷ Ad Spend
If you spent $1,000 on Google Ads and generated $4,000 in conversion value, your ROAS is 4× (or 400%)
ROAS Percentage = (Conversion Value ÷ Ad Spend) × 100%
Suggested Target ROAS = Current ROAS × 0.9 (conservative approach)
