ROAS (Return on Ad Spend) is a marketing metric that measures the revenue generated for every dollar spent on advertising. ROAS is calculated by dividing total revenue by total ad spend. For example, if you spend $1,000 on ads and generate $4,000 in revenue, your ROAS is 4.0x — meaning you earn $4 for every $1 spent.

What does ROAS stand for?

ROAS stands for Return on Ad Spend. It is the most widely used metric for measuring advertising efficiency. A ROAS of 1.0x means you break even — every dollar spent returns exactly one dollar in revenue. A ROAS above 1.0x means you're generating more revenue than you spend.

A good ROAS depends on your industry, profit margins, and business model. The cross-industry average ROAS is approximately 2.19x. For e-commerce, 3–4x is generally considered good. A business with 40% profit margins needs a minimum ROAS of 2.5x to break even, and should target 3.75–5x for sustainable growth. Use this calculator to find your personal break-even ROAS.

What is break-even ROAS?

Break-even ROAS is the minimum ROAS you need to cover your costs. The formula is: Break-even ROAS = 1 ÷ Profit Margin. If your profit margin is 40%, your break-even ROAS is 2.5x. Industry best practice is to target 1.5–2x your break-even ROAS to cover overhead and generate sustainable profit.

What's the difference between ROAS and ROI?

ROAS measures revenue generated per dollar of ad spend (Revenue ÷ Ad Spend), while ROI measures profit after all costs ((Revenue − Total Cost) ÷ Total Cost × 100%). ROAS focuses purely on advertising efficiency; ROI gives you the complete profitability picture including COGS and overhead. You need both metrics for a full view of campaign performance.

How do iOS privacy changes affect ROAS tracking?

Apple's App Tracking Transparency (ATT), introduced with iOS 14.5, limits ad platforms' ability to track conversions from iPhone users. This means your reported ROAS on Facebook and Instagram may be 20–30% lower than your actual ROAS. To improve accuracy: use server-side tracking, implement Conversions API, and cross-reference with first-party data from your store or Google Analytics.

What costs should I include in my ad spend?

For the most accurate ROAS, include all advertising-related costs: platform ad spend (what you pay Facebook, Google, TikTok, etc.), creative production costs (video, images, copywriting), landing page costs, agency or freelancer fees, and tool subscriptions. Example: $5,000 platform spend + $1,000 creative + $500 tools = $6,500 total ad spend.

What is an attribution window?

An attribution window is the time period after an ad interaction during which a conversion is credited to that ad. Common windows: Facebook uses 7-day click / 1-day view; Google uses 30-day click / 1-day view; TikTok uses 7-day click / 1-day view; LinkedIn uses 90-day click. Different attribution windows can make the same campaign appear to have very different ROAS figures across platforms.

How often should I check my ROAS?

Monitor ROAS weekly for active campaigns and daily during launches or high-spend periods. Allow at least 7–14 days of data before making major optimization decisions — shorter windows can be misleading due to attribution delays and statistical noise.

ROAS & Ad Metrics Glossary

ROAS

Return on Ad Spend — the revenue earned for every dollar spent on advertising. ROAS = 3x means you earn $3 for every $1 spent. The cross-industry average ROAS is approximately 2.19x.

ROAS = Revenue ÷ Ad Spend

ROI

Return on Investment — measures the profitability of an investment after all costs, including COGS and overhead. Unlike ROAS, ROI gives the complete profit picture.

ROI = (Revenue − Cost) ÷ Cost × 100%

CPA

Cost Per Acquisition — the average cost to acquire one customer or conversion. Lower CPA = more efficient campaigns. Compare your CPA to your average order value to assess profitability.

CPA = Ad Spend ÷ Conversions

CPC

Cost Per Click — the average cost for each click on your ad. Average CPC varies widely: Facebook ~$0.97, Google Search ~$2.69, LinkedIn ~$5.26.

CPC = Ad Spend ÷ Clicks

CPM

Cost Per Mille — the cost to show your ad 1,000 times. Lower CPM = more reach per dollar. Average CPM: Facebook ~$7.19, TikTok ~$10.00, YouTube ~$9.68.

CPM = (Ad Spend ÷ Impressions) × 1,000

CTR

Click-Through Rate — the percentage of people who saw your ad and clicked it. Average CTR: Google Search ~2%, Facebook ~0.9%, LinkedIn ~0.5%.

CTR = Clicks ÷ Impressions × 100%

CVR

Conversion Rate — the percentage of clicks that result in a conversion (purchase, signup, etc.). Average CVR: Google ~4.4%, Facebook ~9.2%, TikTok ~1.1%.

CVR = Conversions ÷ Clicks × 100%

Break-Even ROAS

The minimum ROAS needed to cover your costs. If you have a 40% profit margin, your break-even ROAS is 2.5x. Target 1.5–2x your break-even for sustainable growth.

Break-even ROAS = 1 ÷ Profit Margin

Attribution Window

The time period after an ad interaction during which a conversion is credited to that ad. Facebook: 7-day click / 1-day view. Google: 30-day click. LinkedIn: 90-day click.
