Simple enough to explain. Useful enough to act on.
This calculator deliberately avoids false precision. It exposes the commercial assumptions so a marketing and finance team can challenge the same model.

Advertising spend ÷ new customersGross profit after media
(Revenue × gross margin) − ad spendInterpretation
A number becomes valuable when it changes a decision.
Before you scale budget
- Confirm that attributed revenue uses a consistent window
- Include refunds, fulfilment costs and sales-cycle delay
- Compare platform conversions with CRM-qualified outcomes
- Check whether extra volume changes conversion rate or CPC
- Write down the budget decision and review date
ROAS questions
Common questions, direct answers.
What is ROAS?
Return on ad spend is attributed revenue divided by advertising spend. A ROAS of 4.0x means four euros of attributed revenue for each euro spent on media.
What is break-even ROAS?
In this simplified model, break-even ROAS is one divided by gross margin. At a 50% gross margin, the modelled break-even ROAS is 2.0x before overhead and other costs.
Is a higher ROAS always better?
Not automatically. A high ROAS can coexist with low volume, weak attribution or poor lead quality. Read ROAS together with gross profit, customer acquisition cost and qualified pipeline.
Can I use this for B2B marketing?
Yes, as a directional model. For B2B, use won revenue or a consistently weighted pipeline value and allow for the real sales-cycle delay.
