What Is ROAS? How To Calculate It

ROAS (Return on Ad Spend) tells you how much revenue you earn for every dollar spent on ads. It’s simple: divide the revenue from your ad campaign by the total ad spend. For example, if you spend $100 on ads and generate $500 in sales, your ROAS is 5:1 (or 500%).

Here’s why ROAS matters:

• Measure Success: See which campaigns and products are performing best.
• Budget Smarter: Adjust ad spend to stay profitable, even as you scale.
• Plan Growth: Set clear goals and estimate future ad budgets.

Quick Formula:
ROAS = (Revenue from Ads / Total Ad Spend) × 100%

Example: If you spend $5,000 on ads and generate $30,000 in revenue, your ROAS is 6:1 (600%).

Target ROAS depends on your product category and profit margins. For example:

• Consumer Electronics: Average 9.0x
• Home & Kitchen: Average 6.5x

To break even, use this formula:
Break-Even ROAS = 1 / Profit Margin

Improving ROAS? Focus on:

• Keyword Targeting: Use high-performing and cost-effective keywords.
• Ad Formats: Test Sponsored Products, Brands, and Display ads.
• Performance Tracking: Use tools like Amazon’s Campaign Manager to refine strategies.

ROAS helps you make smarter ad decisions, ensuring profitability and growth.

ROAS Calculation Guide

Knowing how to calculate ROAS (Return on Ad Spend) is key to making informed decisions about your ad budget.

Basic ROAS Formula

Here’s the formula you’ll use:

ROAS = (Revenue from Ad Campaign / Total Ad Spend) × 100%

For example, if your campaign brought in $15,000 in sales and you spent $3,000 on ads, the calculation would look like this:

($15,000 / $3,000) × 100% = 500% or 5:1

This means for every $1 spent on ads, you earned $5 in revenue. Let’s break down how to calculate ROAS step by step.

3 Steps to Calculate ROAS

1. Track Ad Campaign Costs

Start by gathering all advertising expenses, such as:

• Pay-per-click (PPC) costs
• Spending on Sponsored Products
• Investments in Sponsored Brands
• Any other promotional expenses

Organize this data by campaign and time period to keep things clear and accurate.

2. Measure Revenue from Ads

Next, track the revenue directly tied to your ads. Use tools like:

• Amazon’s advertising dashboard to monitor ad-attributed sales
• Order values, including variations in product types
• Attribution windows (usually 7-14 days) to capture delayed purchases

Make sure to exclude organic sales for an accurate ROAS calculation.

3. Use the Formula

Here’s a practical example:

Monthly Ad Campaign Data:

• Total ad spend: $5,000
• Revenue from Sponsored Products: $22,500
• Revenue from Sponsored Brands: $7,500

Total revenue: $30,000

Now, calculate ROAS: ($30,000 / $5,000) × 100% = 600% or 6:1

This shows that every $1 spent on ads resulted in $6 in revenue, indicating a strong return on your investment.

Target ROAS Numbers

Target ROAS benchmarks help set realistic ad goals and ensure profitability.

Amazon ROAS Standards by Industry

ROAS performance varies across product categories on Amazon due to factors like profit margins, competition, and customer behavior:

These averages provide a general framework, but your target ROAS should align with your business model, profit margins, and growth goals. To fine-tune your targets, calculate your break-even ROAS.

Break-Even ROAS Formula

Break-Even ROAS = 1 / Profit Margin

Let’s break it down with an example:

• Selling price: $50
• Product cost: $20
• Amazon fees: $10
• Profit margin: 40% (($50 – $20 – $10) ÷ $50)

Using the formula: 1 ÷ 0.40 = 2.5x ROAS

This means you need to generate at least $2.50 for every $1 spent just to break even. To stay profitable, aim for 20–30% above this break-even point.

Other factors to keep in mind:

• Product lifecycle stage
• Seasonal demand
• Competitive landscape
• Long-term customer value

While aiming for a higher ROAS is ideal, setting targets too high could limit your ad reach and slow down growth. Balance profitability with scalability for the best results.

ROAS Improvement Methods

Boosting your ROAS starts with smart strategies that build on your understanding of how to calculate it. Here’s how you can take actionable steps to improve your returns.

Keyword and Audience Targeting

Focus on keywords and audiences that deliver results. Use Search Term Reports to pinpoint:

• High-performing keywords that consistently drive conversions.
• Cost-effective keywords that keep sales steady without inflating ad spend.
• Negative keywords to eliminate wasteful spending on irrelevant searches.

For Sponsored Brand campaigns, segment your audience based on factors like shopping behavior, purchase history, brand preferences, and product interests.

Here’s a tip: Adjust your bids based on when your audience is most active. Increase bids during peak shopping hours and reduce them during slower periods. Also, experiment with different ad formats to see what resonates most with your audience.

Ad Format Testing

Different ad formats serve different goals. Compare them to find what works best:

When testing, run each format for two weeks with consistent daily budgets. Pay attention to metrics like click-through rates, conversion rates, and ACoS. Once you identify the best performers, shift more of your budget toward those formats while keeping smaller tests running for further insights.

Performance Tracking Tools

Amazon offers built-in tools that can help fine-tune your campaigns. Tools like Brand Analytics, Campaign Manager, and Attribution Reports provide deep insights into areas like market basket trends, daily metrics, and the overall customer journey.

Set up dashboards to monitor key metrics such as:

• Daily and weekly trend analysis
• Performance benchmarks for specific categories
• Seasonal changes in customer behavior
• Competitor pricing trends

With these tools and strategies, you can refine your approach and make data-driven decisions to improve your ROAS.

Conclusion

Improving ROAS is key to staying competitive on Amazon. This metric – how much revenue you earn for every ad dollar spent – helps guide smarter, more profitable decisions.

The formula is simple: divide total ad revenue by total ad spend. Yet, the insights it provides can shape your entire advertising strategy.

Key points to remember:

• Understand your benchmarks: While a 4:1 ratio (earning $4 for every $1 spent) is often seen as strong, your ideal ratio depends on your product category and profit margins.
• Experiment with ad formats: Use Amazon’s analytics tools to fine-tune campaigns and test different approaches.
• Track and adjust constantly: Regularly review performance metrics to keep refining your strategy.

By focusing on these steps, you can make your ad spending more efficient and see steady growth. Testing keywords, experimenting with formats, and tracking results closely will help you maintain a profitable ROAS for your Amazon business.
