ROAS Calculator (Return on Ad Spend)

Return on Ad Spend (ROAS) is a foundational marketing metric that translates total ad expenditure and resulting revenue into a clear multiplier (e.g., 3.5x) or percentage (e.g., 350%). It is the primary KPI used inside ad platforms like Meta Ads Manager, Google Ads, and TikTok Ads to evaluate the top-line efficiency of specific campaigns, ad sets, and creatives.

How do you use this ROAS calculator?

1. Enter Ad Spend: Input the total amount spent on a campaign or advertising channel.
2. Enter Revenue: Input the total revenue generated from that specific ad spend.
3. Get Your Multiplier: The calculator will translate the data into a ROAS Multiplier (e.g., 3.0x), a Percentage(300%), and show the gross profit (revenue minus spend) to help you measure campaign efficiency.

What is ROAS and how does it measure efficiency?

ROAS allows marketers to compare the efficiency of different advertising channels at a glance. To understand ROAS, you need:

• Ad Spend: The exact dollars spent directly on media acquisition.
• Attributed Revenue: The gross revenue the ad platform claims credit for based on its specific attribution window (e.g., 7-day click, 1-day view).
• The Multiplier: A ROAS of 4.0x means that for every $1.00 spent on ads, the campaign generated $4.00 in gross revenue.

How do you calculate ROAS?

The formula for ROAS is simple division. You can express it as a flat multiplier, or multiply it by 100 to express it as a percentage.

• ROAS (Multiplier) = Revenue from Ads / Total Ad Spend
• ROAS (Percentage) = (Revenue from Ads / Total Ad Spend) * 100
• Gross Profit = Revenue from Ads – Total Ad Spend

Why use ROAS instead of Cost Per Acquisition (CPA)?
