What Is a Good ROAS for Google Ads? (By Industry)

One of the most common questions in PPC: "Is our ROAS good?"

The honest answer: it depends. But that's not useful, so here's a more practical breakdown.

The short answer

A ROAS of 4x is often cited as a benchmark — meaning $4 in revenue for every $1 spent. But this number is nearly meaningless without knowing your margins.

Why margins matter more than ROAS

If you're selling a product with a 20% margin, a 4x ROAS means you're barely breaking even:

• Revenue: $4
• Cost of goods (80%): $3.20
• Ad spend: $1
• Profit: -$0.20

At 20% margin, you need a ROAS of at least 5x just to cover costs — before accounting for any other business expenses.

A simple formula to find your break-even ROAS:

Break-even ROAS = 1 ÷ gross margin

Anything above break-even is profitable. Your target ROAS should be meaningfully above this.

Take these with a grain of salt — your results will vary based on competition, ad quality, landing pages, and seasonality.

Lead generation: ROAS vs CPA

For lead generation campaigns, ROAS is often the wrong metric. You're not directly generating revenue from a click — you're generating a lead that may or may not close.

In these cases, track CPA (Cost per Acquisition) instead. See how to explain ROAS to clients for tips on presenting this distinction clearly in reports.

• What does it cost to get a qualified lead?
• What's the close rate on those leads?
• What's the average deal value?

From there you can work backwards to a target CPA that makes the campaign profitable.

How to set a ROAS target for a new client

1. Ask for their gross margin
2. Calculate break-even ROAS
3. Add a profit buffer (typically 20–30% above break-even)
4. Set that as the target

Example: 40% margin → break-even ROAS = 2.5x → target ROAS = 3x–3.5x

Then track actual ROAS monthly and adjust bids and targeting accordingly.

When to worry about ROAS

• ROAS drops more than 20% month-over-month without a clear reason
• ROAS is consistently below break-even
• ROAS looks good but conversion volume is too low to be statistically meaningful

A 10x ROAS on 3 conversions is noise, not signal.

The bottom line

A "good" ROAS is one that's profitable given your margins and growing over time. Start with your break-even number, set a target above it, and report on it consistently so you can spot trends early.
