Growth Calculators
Understand the economics behind your marketing.
Use these calculators to examine acquisition cost, advertising return, margin and break-even performance. They are designed to support better questions and decisions—not replace reliable attribution or financial analysis.

All monetary inputs should use the same currency. Nothing is converted, and no exchange rates are used.
Channel CAC
Estimate the cost of acquiring a customer through a specific campaign or channel.
Channel CAC = campaign or channel spend ÷ new customers acquired
Results appear here once valid values have been entered.
Blended CAC
Estimate the fully loaded acquisition cost across paid media, people, partners and technology.
Blended CAC = total acquisition costs ÷ total new customers acquired
Results appear here once valid values have been entered.
ROAS
Calculate the revenue attributed to advertising for every unit of advertising spend.
ROAS = attributed revenue ÷ advertising spend
Results appear here once valid values have been entered.
Break-even ROAS
Estimate the minimum advertising return required to recover advertising spend before overhead and other costs.
Break-even ROAS = 1 ÷ margin expressed as a decimal. For example: 50% → 2.00×, 40% → 2.50×, 25% → 4.00×.
Results appear here once valid values have been entered.
Margin-adjusted ROAS
Translate attributed revenue into estimated gross profit before comparing it with advertising spend.
Estimated gross profit = attributed revenue × margin percentage. Margin-adjusted ROAS = estimated gross profit ÷ advertising spend. Estimated amount after advertising spend = estimated gross profit − advertising spend.
Results appear here once valid values have been entered.
Use the numbers to improve the decision.
A calculator can show what happened based on the inputs provided. It cannot determine whether attribution is reliable, whether the customers are valuable or whether the result can be scaled. Review these figures alongside lead quality, conversion, sales velocity, retention and customer value.
- Are acquisition costs being calculated consistently?
- Does attributed revenue reflect the full customer journey?
- Is margin based on realistic fulfilment and delivery costs?
- Are different channels being compared over equivalent time periods?
- Is the business optimising for customers and commercial value rather than leads alone?

The numbers are most useful when they are connected to positioning, channel choices, conversion, capacity and realistic growth targets.
