ROAS Calculator
Calculate ROAS metrics for ecommerce, SaaS, marketing, and operations.
This ROAS calculator finds Return on Ad Spend - the revenue generated for every dollar spent on advertising - a key profitability indicator for evaluating whether ad campaigns are worth their cost.
Enter your total revenue from ads and total ad spend, and the calculator returns your ROAS.
Worked Calculation Examples
| Scenario | Result | Calculation Step |
|---|---|---|
| $8,000 revenue from $2,000 ad spend | ROAS = 4x | ROAS = 8,000 ÷ 2,000 = 4x - every $1 spent generated $4 in revenue. |
| $15,000 revenue from $5,000 ad spend | ROAS = 3x | ROAS = 15,000 ÷ 5,000 = 3x. |
The ROAS Formula
ROAS = revenue from ads / ad spend, often expressed as a ratio (like 4:1) or a multiple (4x). A ROAS of 4x means every $1 spent on ads generated $4 in revenue - it's a top-line revenue metric, not a profit metric, since it doesn't subtract the cost of goods or other expenses.
ROAS vs. ROI: Revenue vs. Profit
ROAS looks only at revenue generated relative to ad spend, while ROI (return on investment) factors in total costs, including product cost, shipping, and overhead, to measure actual profit. A campaign can show a strong ROAS while still being unprofitable once all costs are considered, which is why ROAS should be paired with margin data for a complete picture.

Frequently Asked Questions
How do you calculate ROAS?
Divide revenue generated from ads by the total ad spend: ROAS = revenue / ad spend, often expressed as a multiple like 4x.
What is a good ROAS?
It depends heavily on profit margins - a business with thin margins may need a much higher ROAS to be profitable than a business with high margins, so there's no universal target that applies to every business.
Is ROAS the same as profit?
No - ROAS measures revenue generated relative to ad spend, not profit. A high ROAS campaign can still be unprofitable if product costs, shipping, and other expenses eat into the margin on that revenue.

What formula does this roas use?
The formula is: ROAS = Revenue from Ads ÷ Ad Spend. ROAS rose to prominence as a standard marketing metric alongside the growth of trackable digital advertising in the 2000s and 2010s, when conversion tracking pixels and attribution software first made it possible to connect specific ad spend directly to specific resulting revenue - a level of measurement precision that traditional media like TV and print advertising had never been able to offer marketers.
