Target ROAS in Google Ads: How to Set It Right

What Target ROAS does, how to find your break-even, and how to set a target that grows profit instead of choking your traffic.

Quick answer

Target ROAS is a Smart Bidding strategy that sets bids to hit an average return on ad spend you choose. The starting point is your break-even ROAS, which equals 1 divided by your gross margin — at a 40% margin, that’s 2.5x. Set your target above break-even, near your recent actual ROAS, and tighten slowly. Pushing it too high improves efficiency but starves your campaign of traffic.

📢
2026 updateFrom 17 August 2026, Target ROAS optimises more consistently to the target you set, even when you change budgets. If your campaign has been beating its target, lower the target to your recent actual ROAS to keep that performance (a Bid Target Adjustment Tool can do this for you).
1What it is

Target ROAS bids to hit a return on ad spend

Target ROAS (tROAS) is a Smart Bidding strategy that sets your bids to achieve an average return on ad spend you choose. You tell Google the revenue you want back per rupee spent, and its AI predicts the value of each search and bids higher on the ones likely to be worth more.

ROAS = conversion value ÷ ad spend  •  a tROAS of 400% means you want ₹4 back per ₹1 spent

Your break-even ROAS is set by your profit margin. Enter your gross margin to see the ROAS you must beat to make a profit — then check where your current ROAS stands.

Set the target against your margin, not a guess

Before you pick a target, you need your break-even ROAS — the point where ad revenue exactly covers product cost. It’s simply the inverse of your gross margin:

break-even ROAS = 1 ÷ gross margin

At a 40% margin, break-even ROAS is 1 ÷ 0.40 = 2.5x. Any tROAS above 2.5x is profit; below it, you lose money on every sale. The calculator above does this for you and checks where your current ROAS sits.

3How to set it

Earn the right to use tROAS

  • Track conversion value, not just conversions — tROAS needs revenue data to optimise toward.
  • Build history first. Report values across your campaigns for around four weeks (or three conversion cycles) before switching on value-based bidding; ideally you’re already running Target CPA.
  • Start realistic. Set your first target near your recent actual ROAS, then tighten in small steps.
  • Don’t over-reach. A target set too high starves the campaign of traffic, because Google only bids on the safest, highest-value searches.
⚠️
Higher target isn’t always betterPushing tROAS up improves efficiency but shrinks volume. The best target is the one that maximises total profit, not the highest ratio you can hit.
Key takeaways
  1. Target ROAS bids to achieve an average return on ad spend you set.
  2. Break-even ROAS = 1 ÷ gross margin; below it you lose money on each sale.
  3. tROAS needs conversion value tracking and several weeks of value history first.
  4. Set the first target near your recent actual ROAS, then tighten in small steps.
  5. A target set too high improves efficiency but shrinks total volume and profit.
?Frequently asked

Target ROAS FAQs

What is Target ROAS in Google Ads?
Target ROAS is a Smart Bidding strategy that sets your bids to achieve an average return on ad spend you choose, using Google’s AI to predict and prioritise higher-value searches.
How do I calculate break-even ROAS?
Break-even ROAS is 1 divided by your gross profit margin. At a 40% margin it is 1 / 0.40 = 2.5x, meaning you need 2.5 rupees back per rupee spent just to break even.
What is a good Target ROAS?
One set above your break-even ROAS and near your recent actual ROAS. The best target maximises total profit, not the highest ratio, because pushing it too high reduces traffic.
Why is my Target ROAS limiting traffic?
A target set too high means Google only bids on the safest, highest-value searches, which shrinks your volume. Lower the target toward your recent actual ROAS to recover traffic.
What do I need before using Target ROAS?
Conversion value tracking and roughly four weeks, or three conversion cycles, of reported value data. Ideally you are already running Target CPA before switching to value-based bidding.
How should I adjust Target ROAS over time?
Change it in small steps and give each change a learning period. From August 2026, campaigns hold to your stated target more consistently, so set it to your recent actual ROAS to lock in performance.
