About This Calculator
Our ROAS Calculator (Return on Ad Spend) helps marketers, business owners, and advertisers measure how much revenue their advertising campaigns generate for every dollar spent. Simply enter your total ad revenue and ad spend to instantly calculate your ROAS ratio, ROAS percentage, net profit or loss, and profit margin. This essential marketing metric helps you evaluate campaign effectiveness, compare channel performance, and make data-driven budget allocation decisions.
ROAS is calculated using the formula: ROAS = Revenue from Advertising ÷ Cost of Advertising. The result is expressed both as a ratio (e.g., 5:1 meaning $5 earned per $1 spent) and as a percentage (e.g., 500%). For example, if you spend $2,000 on Facebook ads and generate $10,000 in revenue, your ROAS is 5:1 or 500%, meaning you earned $5 for every $1 spent. The calculator also shows your net profit (revenue minus ad spend) and profit margin percentage, giving you a complete picture of campaign profitability.
ROAS is different from ROI — while ROAS measures gross revenue against ad spend only, ROI accounts for all costs including cost of goods sold, operating expenses, and overhead. A good ROAS depends on your profit margins: businesses with 25% profit margins need a ROAS of at least 400% to break even after accounting for product costs. The calculator helps you determine whether your campaigns are truly profitable after removing advertising costs.

Frequently Asked Questions
What is ROAS in advertising?
ROAS (Return on Ad Spend) is a marketing metric that measures the amount of revenue generated for every dollar spent on advertising. It is calculated by dividing total advertising revenue by total ad spend. ROAS helps businesses evaluate the effectiveness of their advertising campaigns and determine which channels deliver the best return.
How do you calculate ROAS?
ROAS is calculated by dividing total advertising revenue by total ad spend. The formula is: ROAS = Revenue from Advertising / Cost of Advertising. For example, if you spend $1,000 on ads and generate $5,000 in revenue, your ROAS is 5:1 or 500%. A ROAS above 100% indicates profitable advertising.
What is a good ROAS?
A good ROAS depends on your industry, profit margins, and business goals. Generally, a ROAS of 4:1 (400%) is considered profitable for most e-commerce businesses, while 8:1 (800%) or higher is excellent. However, businesses with higher margins may profit from lower ROAS. Break-even ROAS is 1:1 (100%), meaning revenue equals ad spend.
What is the difference between ROAS and ROI?
ROAS (Return on Ad Spend) measures the gross revenue generated per dollar spent on advertising, while ROI (Return on Investment) measures the net profit after accounting for all costs including cost of goods sold, operating expenses, and overhead. ROAS focuses specifically on ad campaign performance, while ROI evaluates overall business profitability.
How can I improve my ROAS?
You can improve ROAS by optimizing ad targeting to reach higher-intent audiences, refining ad creative and copy for better conversion rates, using negative keywords to eliminate wasted spend, improving landing page experience, testing different ad platforms, retargeting warm audiences, and analyzing campaign data to reallocate budget to top-performing channels.
What is the difference between ROAS and CPA?
ROAS measures revenue generated per dollar spent on ads (revenue / ad spend), while CPA (Cost Per Acquisition) measures the cost to acquire a customer (ad spend / conversions). ROAS focuses on revenue efficiency while CPA focuses on cost efficiency. A high ROAS paired with a low CPA indicates strong advertising performance.
How do I calculate break-even ROAS?
Break-even ROAS is 1:1 or 100%, meaning your advertising revenue exactly equals your ad spend. Any ROAS above 100% generates profit, while anything below 100% results in a loss. To account for cost of goods sold, use: Break-even ROAS = 1 / Profit Margin. For example, with a 25% profit margin, your break-even ROAS is 4:1 or 400%.
What ROAS should I target for Google Ads and Facebook Ads?
For Google Ads (Search), a good ROAS target is typically 400% (4:1) for e-commerce and 300% (3:1) for lead generation. For Facebook Ads, a ROAS of 300% (3:1) is considered good for most businesses. However, targets vary by industry — SaaS companies may accept lower ROAS due to high customer lifetime value, while retail businesses need higher ROAS due to lower margins.
