How to Calculate ROAS: Formulas, Examples, and Tips

Last Updated:  
November 18, 2024

If you’re running ads to boost your ecommerce business, you’ve probably asked yourself: how effective are they?

Knowing how to calculate ROAS—Return on Ad Spend—gives you a clear answer. ROAS is a crucial metric for understanding whether your ad dollars are turning into real revenue or just clicking away.

With global digital ad spending expected to reach over $740 billion by 2024, ecommerce businesses are investing heavily in ads to capture customer attention.

However, calculating and improving ROAS isn’t always easy. Many businesses struggle to capture accurate data, optimize campaigns, and consistently track performance.

This is where Triple Whale steps in. As a powerful ecommerce data analytics solution, Triple Whale simplifies ROAS tracking and optimization, giving you a clear view of what’s working.

In this guide, we’ll dive into what ROAS is, how to calculate it, and why it matters so much. We’ll also look at common pitfalls and advanced strategies to help you get the most out of every ad campaign.

Let’s explore how you can track this metric effectively and keep your advertising and marketing campaigns on the path to success.

What is ROAS?

ROAS (Return on Ad Spend), tells you how much revenue you’re getting back for every dollar you put into ads. If you’re spending money to get customers’ attention, you want to know it’s working—and that’s where ROAS comes in.

Now, why is ROAS so crucial? Because it’s the clearest indicator of whether your ads are pulling their weight. By tracking this marketing metric, you’ll know right away if your ad dollars are generating the revenue you expect. Think of it as a quick thumbs-up (or down) on your ad strategy.

Let’s say you spend $1,000 on ads and make $5,000 in revenue from them. That’s a ROAS of 5:1. For every dollar you spent, five came back in revenue. 

Not too shabby, right?

ROAS vs. ROI

But what about ROI (Return on Investment)? Well, that’s the big-picture metric. While ROAS zeroes in on ad-specific spending and revenue, ROI considers everything: production costs, shipping, overhead—you name it. In other words, ROI tells you if your entire investment pays off, not just the ads.

In ecommerce, ROAS and ROI both matter. ROAS gives you a fast check on ad effectiveness, while ROI gives you the full profit story. Balancing the two helps you get a clearer view of your marketing success—and avoid the classic trap of great ads that don’t add up financially.

Why is ROAS Important for Ecommerce Businesses?

For ecommerce businesses, ROAS is a powerful tool for making smart, strategic decisions about where to put your ad dollars. With ROAS, you know if your ads are generating enough revenue to justify their advertising spend. This insight is essential when you’re planning budgets and figuring out which campaigns deserve more fuel—and which might need a little tweaking.

Imagine this: You run a campaign with a solid ROAS of 6:1. For every dollar spent, you’re getting $6 back in revenue. That’s a sign your campaign is on fire, and you can confidently scale it up, knowing it’s pulling in solid returns.

On the other hand, if your ROAS drops to 1:1, you know it’s time to hit pause, reassess, and optimize before spending more.

A good ROAS can drive profitability and make scaling easier. When your ads perform well, you have more room to invest in growth, new products, or even additional ad channels. It’s all about maximizing the impact of each dollar you put into advertising.

What is a good ROAS?

While the average ROAS across industries tends to hover around 2:1, a healthy benchmark to aim for is around 4:1. This means $4 in revenue for every $1 spent. But in some cases—like high-margin products or niche markets—you might see businesses aiming for a 10:1 ratio or higher.

Keeping an eye on ROAS can help you strike that balance between spending and earning. With tools like TripleWhale, you’ll get the clarity you need to spot high-performing campaigns, refine budgets, and keep your business profitable, one ad dollar at a time.

How to Calculate ROAS: The Formula for Ad Spend

Calculating ROAS is refreshingly simple when you use the ROAS formula. The formula goes like this:

ROAS = (Revenue from Ads) / (Cost of Ads)

Let’s break that down. The “Revenue from Ads” is the total income generated by your ads—everything earned from clicks that convert to sales. The “Cost of Ads” includes all the expenses directly tied to those ads, like ad placement costs, creative spend, and so on.

For example, if you spent $5,000 on a Facebook ad campaign and earned $20,000 from it, you’d calculate your ROAS like this:

ROAS = $20,000 / $5,000 = 4:1

This means that for every dollar spent, you earned $4 back. That’s a pretty solid result! A ROAS of 4:1 or higher is generally a good indicator that your campaign is effective and profitable.

Understanding ROAS Analysis

ROAS analysis is a crucial step in evaluating the effectiveness of an ad campaign. It helps businesses understand the revenue generated by their advertising efforts and make data-driven decisions to optimize their ad spend. By analyzing ROAS, businesses can identify areas of improvement, optimize their ad campaigns, and increase their return on investment (ROI).

To perform a thorough ROAS analysis, you can use various tools and techniques. For instance, Google Ads provides detailed insights into your ad performance, allowing you to see which campaigns are driving the most revenue. Excel can be used to create custom reports and track your ROAS over time. Data analytics software, like Triple Whale, offers advanced features for tracking and optimizing your ROAS across multiple ad platforms.

By regularly analyzing your ROAS, you can pinpoint which ad campaigns are delivering the best results and allocate your ad spend more effectively. This ensures that every dollar you invest in advertising is working hard to drive revenue and growth for your business.

Common Mistakes When Calculating ROAS

Calculating ROAS may look straightforward, but it’s easy to make mistakes that can lead to inaccurate results. These little missteps can add up, resulting in a skewed view of your digital marketing efforts and ad performance.

Let’s go over some common errors and how to avoid them so you can keep your ROAS numbers on point.

  • Forgetting all costs. Many people focus only on ad spend but forget other expenses. Remember to include software subscriptions, design costs, or other fees directly related to the campaign.
  • Ignoring overhead costs. Overhead might not feel as directly tied to ads, but it still impacts your profitability. Think about costs like account management, creative production, and any tools your team uses to run the campaign.
  • Not accounting for discounts or promotions. If your ad includes a discount or a special promotion, make sure to factor that into your revenue calculations. Promotions can impact the total revenue generated, which influences your ROAS.
  • Using gross revenue instead of net revenue. ROAS should be based on the revenue after returns and refunds. Calculating based on gross revenue gives an overly optimistic view of your results.

To avoid these pitfalls and get an accurate ROAS, consider these tips:

  1. List all costs. Keep a checklist of expenses, including the less obvious ones. This will ensure you’re capturing the complete cost of each campaign.
  2. Review revenue figures carefully. Always base ROAS calculations on net revenue to get a true sense of returns.
  3. Use TripleWhale’s ROAS Calculator. Our calculator helps you double-check each input, ensuring that every dollar and cost is accounted for.

Avoiding these common pitfalls will give you a clearer picture of your campaign performance, making your ad budget decisions sharper and more effective!

How to Improve ROAS in Advertising Campaigns

Once you’ve nailed the basics of ROAS, it’s time to dive deeper. Integrating various marketing tools can help you fine-tune your campaigns, maximize returns, and make sure every ad dollar is hard at work.

Here are some powerful methods to boost your ROAS:

  • Segmentation. Tailor your ads to different customer groups. By segmenting audiences based on behavior, demographics, or purchase history, you can create ads that resonate on a personal level.
  • A/B Testing. Experiment with different versions of your ads to see which one performs best. Test elements like images, copy, and CTAs to understand what drives clicks and conversions.
  • Attribution modeling. Understand which touchpoints drive results. Attribution modeling helps you see where your ads have the most impact along the customer journey, so you can invest in the best-performing channels.

Ad Campaign Optimization

how to effectively trak and optimize ROAS

Ad campaign optimization is the process of improving the performance of an ad campaign to achieve better results. This involves fine-tuning various elements of your campaign, such as ad targeting, ad creative, bidding strategies, and landing pages.

To start, focus on optimizing your ad targeting. By segmenting your audience based on behavior, demographics, or purchase history, you can create more personalized and relevant ads. This increases the likelihood of conversions and improves your ROAS.

Next, experiment with different ad creatives. A/B testing different versions of your ads can help you identify which images, copy, and calls-to-action (CTAs) resonate most with your audience. This allows you to refine your ads and boost their effectiveness.

Bidding strategies also play a crucial role in ad campaign optimization. Adjusting your bids based on performance data can help you get the most out of your ad spend. For example, you might increase bids for high-performing keywords or reduce bids for underperforming ones.

Finally, ensure that your landing pages are optimized for conversions. A well-designed landing page with a clear CTA can significantly improve your conversion rate and ROAS.

Ad campaign optimization requires ongoing monitoring and analysis of ad performance data. By continuously testing and experimenting with different strategies, you can improve your ROAS, increase conversions, and reduce your cost per acquisition (CPA).

Attribution Modeling and Customer Acquisition Cost (CAC)

Attribution modeling is the process of assigning credit to different marketing channels and touchpoints for driving conversions. This is important for understanding the true impact of an ad campaign on customer acquisition and revenue generation.

There are various attribution models to choose from, such as first-click, last-click, and multi-touch attribution. Each model provides a different perspective on how your marketing efforts contribute to conversions. By using attribution modeling, you can identify which channels and touchpoints are most effective and allocate your ad spend accordingly.

Customer acquisition cost (CAC) is another important metric for evaluating the effectiveness of an ad campaign. CAC is the cost of acquiring a new customer, and it helps you understand how much you’re spending to bring in new business. By comparing your CAC to your customer lifetime value (CLV), you can determine if your ad campaigns are profitable.

Understanding CAC and attribution modeling allows you to optimize your ad spend and improve your ROAS. By focusing on the most effective channels and reducing your CAC, you can drive more revenue and achieve better results from your ad campaigns.

Tracking ROAS doesn’t have to be complicated—especially with the right tools on hand. 

For ecommerce brands, Triple Whale’s ecommerce operating system is a standout. It’s designed to centralize all your metrics, offering a full view of ad performance across channels. With Triple Whale, you get real-time insights, which means no more guessing on whether your ads are hitting the mark.

  • Shopify Integrations. They help tie revenue back to your ad spend. 

Each of these has unique strengths, but the real power comes when you use them together to capture a complete picture of your ad performance.

When it comes to calculating ROAS, you have two options: manual or automated. Manually calculating ROAS might work for one or two campaigns, but it quickly becomes overwhelming as you scale up. This approach risks errors and can be time-consuming, especially if you’re pulling data from multiple sources.

That’s where automated platforms, like Triple Whale, really shine. They handle calculations instantly, integrate seamlessly with your ecommerce tools, and even automate daily updates. 

Using an integrated approach saves time and keeps your ROAS accurate, allowing you to focus on improving strategy instead of chasing numbers.

Practical Examples of ROAS Calculation

Let’s break down ROAS with two real-world examples of advertising campaigns: a small start-up and a larger ecommerce business. These scenarios highlight how ROAS works at different scales, showing both simple and more complex calculations.

Imagine a start-up spends $500 on a social media ad campaign and earns $2,000 in revenue from it. To calculate ROAS, divide the revenue by the ad spend:

ROAS = $2,000 / $500 = 4:1

This means they made $4 for every $1 spent—a solid return! With a tight budget, knowing this ROAS can guide their future ad investments, helping them identify what works without overspending.

Now, let’s look at a larger ecommerce business. Say they invest $50,000 in ads across multiple channels and bring in $150,000 in revenue. Using the same formula:

ROAS = $150,000 / $50,000 = 3:1

For every dollar spent, they’re earning $3. While the return is slightly lower, this larger-scale campaign can focus on other metrics, like lifetime customer value, to guide ad strategies.

In both cases, calculating ROAS provides valuable insight. Whether you’re a small start-up or a big business, knowing your ROAS lets you make informed decisions about budget allocation and campaign scaling. With TripleWhale’s tools, you can track ROAS effortlessly, ensuring your ad spend aligns with your growth goals.

Mastering ROAS: Final Tips on How to Calculate ROAS

Knowing how to calculate ROAS for your advertising campaigns can be a game-changer for your business. Tracking this metric not only helps you understand how well your ads are performing but also lets you make smarter decisions about budget and campaign strategy.

Remember, a strong ROAS is great, but it’s only part of the bigger picture. Pairing ROAS with other metrics like ROI ensures you’re looking at both short-term wins and long-term profitability. Use these insights to keep your marketing dollars working harder for you.

With TripleWhale, tracking and improving ROAS is simple and intuitive. So go ahead—analyze, adjust, and keep pushing for the growth you’re after.
