If you’ve ever run a digital ad campaign, whether on Meta, Google, TikTok, or anywhere else, you’ve probably wondered one thing: Is this actually working?
In the world of paid advertising, success isn’t based on assumptions. It’s measured. Most business owners can't answer that question with actual numbers.
They know their ad spend, they know their revenue is up or down, but they don't know if the ads are profitable or just burning cash.
ROAS, Return on Ad Spend, answers that question directly. It is one of the most reliable metrics used across the industry.
We work with brands across Canada that want to understand their advertising results more clearly, especially when budgets are tight, and every decision needs to count.
We’ve seen businesses transform their advertising by actually measuring ROAS instead of just looking at clicks or impressions or other metrics that don't connect to revenue.
ROAS helps businesses see which campaigns are driving real revenue and which ones need to be optimized or paused.
In this article, we’ll break down what ROAS means, how to interpret it, how to calculate it, and what a good ROAS looks like for your business.
What Is ROAS
ROAS stands for Return on Ad Spend.
It's the metric showing you exactly how much revenue you're generating for every dollar spent on advertising.
If you spend $100 on ads and generate $400 in revenue from those ads, your ROAS is 4:1.
The ROAS meaning is straightforward; it's an efficiency measure for advertising spend.
Higher ROAS means your ads are more efficient at generating revenue. Lower ROAS means you're spending more to generate less. This might still be okay for some companies, depending on profit margins and other factors, but you need to know the exact numbers.
ROAS vs ROI
ROAS is different from ROI, Return on Investment.
ROI considers all costs, including ad spend, product costs, overhead, and everything else. ROAS specifically measures return on advertising spend only.
This makes it a clearer metric for evaluating advertising performance without getting tangled up in other business costs.
Importance of ROAS Marketing
In ROAS marketing, this metric drives decisions about which campaigns to scale, which to optimize, and which to kill.
For example, if one campaign has 8:1 ROAS and another has 2:1 ROAS, you know where to put more budget and where to make changes.
ROAS applies to any paid advertising, be it Google Ads, Facebook ads, Instagram ads, TikTok ads, display advertising, or any other. Any time you're paying for advertising, you should be tracking ROAS to understand if that spend is working.
The power of ROAS is that it cuts through all the noise and helps you see the actual picture.
It doesn't matter if an ad got 10,000 impressions if it only generated $50 in revenue on $200 spend. That's 0.25:1 ROAS, which means it lost money. Meanwhile, an ad with only 500 impressions that generated $800 on $100 spend has an 8:1 ROAS and is printing money.
The shift from vanity metrics to revenue metrics changes everything about how you approach paid advertising.
The ROAS Formula and How to Calculate ROAS
The ROAS formula is dead simple:
Revenue from Ads ÷ Ad Spend = ROAS.
Example: You spent $1,000 on Facebook ads last month. Those ads generated $5,000 in revenue. ROAS = $5,000 ÷ $1,000 = 5 (or 5:1 or 500%).
It’s simple. The challenge isn't calculation; it's accurately tracking which revenue came from which ads.
How to calculate ROAS in practice requires attribution. You need to know that this purchase came from that ad campaign.
Most advertising platforms provide this attribution in their reporting. They track clicks, conversions, and revenue back to specific campaigns.
However, attribution gets messy. Customers might see a Facebook ad, later Google your company, and then click the email link before buying. Which ad gets credit?
Different attribution models handle this differently. Last-click attribution gives credit to the last thing the customer clicked. First-click gives credit to the first interaction. Multi-touch tries distributing credit across touchpoints.
For ROAS calculation, most businesses use platform-reported conversion values. Google Ads tells you how much revenue campaigns generated. Facebook tells you the revenue from its ads. These numbers aren't perfect, but they're consistent enough to guide decisions.
It is important to note that ROAS measures revenue, not profit. If your ROAS is 3:1 but your profit margin is 25%, you're actually losing money on those ads. Always consider profit margins alongside ROAS.
The breakeven ROAS depends on your margins. If you have a 50% profit margin, breakeven ROAS is 2:1. If you have a 25% profit margin, breakeven ROAS is 4:1. Below breakeven ROAS, you're losing money on ads even though revenue is coming in.
What Is a Good ROAS
There's no universal answer because it depends on your industry, profit margins, business goals, and stage of growth. But here are some general guidelines.
Every industry, business model, and profit margin is different. A ROAS that works for a high-margin brand may not work for one with tight margins.
But here are some general benchmarks:
E-commerce
For e-commerce, 4:1 ROAS is often considered a decent baseline. Below that, and you're probably not profitable after accounting for product costs, shipping, and overhead. Above 4:1 and you're in solid territory.
Above 8:1 and you're doing really well, or need to scale up spend to capitalize on what's working.
Lead Generation
For lead generation businesses, like B2B services or high-ticket services, ROAS calculation works differently because revenue isn't immediate.
You're measuring the value of leads generated against ad spend. If leads convert to customers worth $10,000 on average and you're getting leads for $100, that's excellent, even though ROAS might look lower initially.
Service Businesses
Service businesses often see lower ROAS on paper, but higher lifetime value. Acquiring customers for $500 through ads when the average customer lifetime value is $5,000 is great business, even though immediate ROAS might only be 2:1 or 3:1.
Startups
The startup growth phase might accept lower ROAS to acquire customers quickly and build market share. Once you've got a customer base and are focusing on profitability, you'd tighten ROAS requirements.
Premium or Luxury Goods
Premium products with high margins can operate profitably at lower ROAS. Luxury goods with 70% margins can be profitable at 2:1 ROAS. Budget products with 20% margins need 6:1+ ROAS to be profitable.
Geographic differences matter too. Canadian advertising costs differ from U.S. Competition levels, audience sizes, and cost-per-clicks vary. ROAS that's normal in Toronto might be different from what's normal in Calgary or Montreal.
The real question isn't ‘what's good ROAS’ universally. It's ‘what ROAS makes my business profitable given my specific margins, costs, and goals?’.
Calculate your breakeven ROAS based on margins, then target something meaningfully above that.
How ROAS Fits into the Bigger Picture
ROAS is a crucial metric, but it's not the only metric that matters. Looking at ROAS in isolation can lead to bad decisions.
Before you start ROAS marketing, it helps to understand the core marketing strategy and concepts that shape customer behaviour and influence how people share brands.
Customer lifetime value (CLV) is a critical context for ROAS. If you're only looking at immediate ROAS, you might kill campaigns that acquire customers who end up being very valuable over time.
First purchase might have 2:1 ROAS, but if those customers stick around and keep buying, the true return is way higher.
Some campaigns drive awareness that leads to conversions later through different channels.
Brand campaigns might have terrible direct ROAS, but they lift overall performance because people become aware of your brand, then later convert through search or direct traffic. Multi-touch attribution helps capture this, but it's imperfect.
Testing and optimization phases often have lower ROAS. New campaigns need time to optimize. If you kill everything that doesn't immediately hit target ROAS, you never let campaigns mature to potential profitability. Give campaigns a reasonable testing period before making decisions.
Seasonality affects ROAS dramatically. Q4 holiday shopping typically sees higher ROAS than February doldrums. Compare ROAS year-over-year or season-over-season, not month-to-month.
Making ROAS Work for Your Business
The transformation is dramatic when you go from ‘we're spending money on ads’ to ‘we know exactly what each dollar of ad spend generates in revenue.’
Start by calculating your breakeven ROAS. Know what you need to hit to be profitable. Everything else flows from that number.
Set up proper conversion tracking across all advertising platforms. Without accurate tracking, ROAS is meaningless. Invest time getting this right before spending big money on ads.
Look at ROAS alongside other metrics, like conversion rate, cost per acquisition, and customer lifetime value. A complete picture requires multiple metrics, not just ROAS.
Return on ad spend isn't a complicated metric, but using it strategically to guide advertising decisions separates profitable businesses from ones burning money. Know your ROAS, understand what drives it, and optimize relentlessly.
Hire professionals who can help your business implement ROAS tracking and use it to make smarter advertising decisions. Your advertising budget deserves that much attention.
