ROAS Calculator
Calculate your return on ad spend instantly and understand how much revenue your advertising generated for every unit of ad spend.

How much did you spend on advertising?
How much revenue did your advertising generate?
ROAS measures revenue generated relative to advertising spend. It does not account for other business costs unless those costs are included separately in your analysis.

Enter your advertising spend and revenue to calculate ROAS.
How ROAS is calculated
ROAS = Revenue Generated ÷ Advertising Spend
ROAS Percentage = ROAS × 100
$10,000 ad spend
$40,000 revenue
$40,000 ÷ $10,000 = 4.00x ROAS
A 4.00x ROAS means $4 in attributed revenue was generated for every $1 spent on advertising.
For every $1 spent on advertising, the campaign generated $4 in attributed revenue. This is an illustrative example, not a BUZZ client result.
What does ROAS tell you?
ROAS provides a ratio between advertising spend and attributed revenue. It can help marketers compare campaign performance, evaluate advertising efficiency, monitor changes over time, and support budget and optimization discussions.
There is no universally "good" ROAS. An appropriate target depends on factors such as gross margin, operating costs, customer acquisition costs, customer lifetime value, attribution model, business model and campaign objective.
ROAS is one piece of the performance picture.
ROAS
Revenue generated relative to advertising spend.
CPA
Cost required to acquire a conversion or customer, depending on the defined conversion.
CAC
Customer acquisition cost. Can include broader acquisition costs beyond media spend depending on how the business defines CAC.
ROI
A broader profitability-oriented measure that can account for costs beyond advertising spend.
ROAS is useful. It is not the whole story.
ROAS alone does not show these parts of the picture:
Profit Margin
Revenue does not equal profitability once costs are factored in.
Operating Expenses
Costs beyond media spend are not reflected in this ratio.
Customer Lifetime Value
A single-purchase ROAS may understate long-term customer value.
Organic Contribution
Some revenue may be influenced by channels beyond paid media.
Incrementality
ROAS doesn't show whether the revenue would have happened anyway.
Attribution Accuracy
Different attribution models can produce different reported ROAS.
Use ROAS alongside the metrics that matter for your business model and campaign objective.
A note on attribution
ROAS depends on how revenue is attributed to advertising. Different platforms and analytics systems can use different attribution methods, so reported ROAS may vary between sources. This calculator performs the arithmetic only; it does not validate or adjust your underlying attribution data.
