Return on Ad Spend (ROAS) is a key performance metric that tells you how much revenue you earn for every dollar spent on advertising. It’s one of the most important numbers for anyone running digital ads—because clicks are nice, but revenue pays the bills.
How to Calculate ROAS
The formula is simple:
ROAS = Revenue from Ads / Cost of Ads
Example: If you made $5,000 in sales from a $1,000 ad campaign, your ROAS is:
$5,000 / $1,000 = 5.0
That means for every $1 you spent, you earned $5 back.
Why ROAS Matters
ROAS helps you:
- Evaluate ad performance across different platforms and campaigns
- Decide where to invest more and where to cut back
- Set realistic budgets and forecast growth
- Measure profitability, not just traffic or clicks
High ROAS = your ads are working.
Low ROAS = something’s broken.
What’s a “Good” ROAS for a WordPress website?
It depends on your margins. A high-ticket SaaS product may do fine with 2.0. An ecommerce store with tight margins may need 4.0 or higher.
General ballpark:
- < 1.0 – You’re losing money
- 1.0 – 2.9 – Barely breaking even
- 3.0 – 4.9 – Decent performance
- 5.0+ – You’re doing great (assuming margins support it)

Frequently Asked Questions
You can, but it’s harder. ROAS works best when you can assign clear dollar values to conversions like purchases, subscriptions, or lead value estimates. For example, if a business averages $500 net income from all their website form submissions you could use Conversion Bridge to set a value for the event to help calculate ROAS.
Not necessarily. Conversion Bridge supports ROAS reporting via several platforms, including Meta, TikTok, Plausible, and others—no GA4 required.
ROAS looks only at ad revenue vs. ad spend. ROI includes all costs (ad spend, production, overhead), making it more comprehensive but harder to calculate cleanly.
ROAS turns your ad spend into a business metric, not a guessing game. It helps you know what’s working, optimize for profit, and scale smarter.
Conversion Bridge ensures your ROAS data is delivered accurately and consistently from your WordPress site to your analytics and ad platforms, making it easier to measure and optimize performance using the tools you already rely on.
