What is Target ROAS?
Target ROAS (Return on Ad Spend) is a Google Ads smart bidding strategy that automatically sets bids to help you achieve a specific return on ad spend. Instead of manually adjusting bids, you tell Google your target (e.g., 400% or 4x), and its algorithm optimizes bids in real-time.
How to Use These Calculators
Enter your target ROAS and planned ad spend to see exactly how much revenue you need to generate — and your expected profit.
Enter your target ROAS, conversion rate, and average order value to find the maximum cost-per-click bid that keeps you profitable.
Target ROAS Formula
Max CPC = (AOV ÷ Target ROAS) × Conversion Rate

Frequently Asked Questions
How do I calculate target ROAS?
Target ROAS is calculated by dividing expected revenue by ad spend. For example, if you want $400 revenue for every $100 spent, your target ROAS is 4x (400%). Use our Revenue Planner calculator above to find your numbers.
What is a good target ROAS for Google Ads?
A good target ROAS varies by industry: E-commerce typically targets 4x-8x, SaaS targets 3x-5x, and lead generation targets 2x-4x. Use our Max CPC Bid calculator to find what works for your specific margins.
What is the difference between target ROAS and target CPA?
Target ROAS focuses on revenue (return on ad spend), optimal for e-commerce. Target CPA focuses on cost per acquisition, better for lead generation where you care about each conversion cost rather than the value.
How long does target ROAS take to work?
Google Ads typically needs a 1-2 week learning phase after switching to Target ROAS. During this time, performance may fluctuate as the algorithm gathers data. It needs at least 30 conversions in the last 30 days to work effectively.
How do I set a target ROAS bid in Google Ads?
In Google Ads, go to a campaign, select a ad group, click on bid strategy, and choose 'Target ROAS'. Enter your desired percentage (e.g., 400% for 4x ROAS). Make sure you have conversion tracking with values set up.
