What Do These Results Mean?
ROAS Ratio
Shows how much revenue you generated for every 1 unit of currency spent on advertising. For example, a 4.00:1 ROAS means you generated 4 in revenue for every 1 spent.
ROAS Percentage
Shows the same return expressed as a percentage. A 400% ROAS means your campaign generated revenue equal to four times the advertising spend.
Revenue per 1 Spent
Shows how much revenue was generated for each £1, $1, €1 or other selected currency unit spent on advertising.
Revenue Above Ad Spend
Shows the difference between attributed advertising revenue and advertising spend.
Important: Revenue Above Ad Spend is not the same as net profit because it does not include product costs, wages, fees, taxes or other business expenses.
Example Calculation
See how ROAS is calculated using a simple advertising campaign example.
Example:
Suppose a business spends £1,000 on an advertising campaign and generates £4,000 in revenue directly attributed to those ads.
Advertising Spend: £1,000
Revenue Generated: £4,000
ROAS Ratio: 4.00:1
ROAS Percentage: 400%
Revenue per £1 Spent: £4.00
Revenue Above Ad Spend: £3,000
Explanation
The campaign generated £4 in revenue for every £1 spent on advertising, giving it a ROAS of 4.00:1 or 400%.
The £3,000 revenue above advertising spend should not be treated as net profit because other business costs and expenses have not been deducted.
ROAS Formula
ROAS measures how much revenue your advertising generates compared with the amount spent on the campaign.
ROAS Ratio
ROAS = Revenue Generated ÷ Advertising Spend
For example:
£4,000 ÷ £1,000 = 4.00
This gives a ROAS of:
4.00:1
ROAS Percentage
ROAS % = (Revenue Generated ÷ Advertising Spend) × 100
Using the same example:
(£4,000 ÷ £1,000) × 100 = 400%
Revenue Above Ad Spend
Revenue Above Ad Spend = Revenue Generated − Advertising Spend
Using the example:
£4,000 − £1,000 = £3,000
Important: ROAS measures advertising revenue relative to ad spend. It does not measure overall business profitability because other costs and expenses are not included.

Frequently Asked Questions
Find answers to common questions about ROAS and measuring advertising performance.
What is a good ROAS?
A good ROAS depends on your industry, profit margins, advertising costs and business goals. A higher ROAS means more revenue is being generated relative to advertising spend, but a campaign can have a positive ROAS and still not be profitable after other business costs are included.
Is ROAS the same as ROI?
No. ROAS focuses specifically on revenue generated compared with advertising spend. ROI is broader and can measure the return after considering additional costs associated with an investment.
Can I use the ROAS Calculator for Google Ads, Facebook or other advertising platforms?
Yes. You can use it for Google Ads, Meta/Facebook Ads, Instagram Ads, TikTok Ads or other advertising campaigns as long as you know the advertising spend and attributed revenue.
Does a 100% ROAS mean I made a profit?
No. A 100% ROAS means the revenue generated equals the amount spent on advertising. It does not mean the business made a profit because product costs, wages, fees, taxes and other expenses are not included.
