See Your Return On Ad Spend
The 321 Web Marketing ROAS calculator will help you evaluate:
Monthly Ad Budget
What are you currently investing across platforms like Google Ads, Facebook, LinkedIn, or Display? Knowing your total monthly spend is the first step in evaluating how efficiently those dollars are working.
Cost-Per-Click (CPC)
Cost-Per-Click, or CPC, is the average amount you pay every time someone clicks your ad. It helps you understand how much you’re spending just to get a single visitor to your website.
Conversion Rates
How many of your visitors turn into leads and how many of those leads become paying customers? These rates show how effective your landing pages, offers, and follow-up processes really are.
Average Customer Value
How much revenue does one closed deal bring in for your business? This number is essential to determine whether your ad spend is delivering a return or draining your budget.

Some Questions The Calculator May Not Have Answered
ROAS (Return on Ad Spend) shows how much revenue your business earns for every dollar spent on ads. It’s one of the clearest ways to measure whether your campaigns are profitable.
Not at all. While we specialize in Google Ads, this calculator works for any paid platform including Facebook, LinkedIn, YouTube, or even display networks.
You’ll want to have your monthly ad budget, average cost-per-click, conversion rates, and the average value of a new customer. If you’re unsure, estimates still provide useful direction.
ROAS measures the return from your ad spend alone, while ROI factors in all costs (like overhead or labor). ROAS is useful for assessing paid campaign efficiency specifically.
Low ROAS means your campaign isn’t generating enough value for what you’re spending. That’s a signal to revisit your targeting, creative, landing pages, or process, and we can help with that.
Yes. Run separate calculations for each campaign, like Search vs. Display, to see which channel is contributing the most to revenue.
