Calculate cost per acquisition using advertising spend and attributed conversions, then explore revenue efficiency when order value is known.
Enter your numbers for a complete standard result. Sign in only when you want to save work.
Fill in the required fields. Optional values add context.
Start with the result. Open the details only when you need them.
Enter your numbers and calculate to see the result.
MPPM will explain what the result means and what to check next.
Work backwards from the outcome you want.
MPPM can help connect cost, traffic and conversion economics into a practical marketing decision.
Free gives you the standard answer. Pro helps you plan targets, compare scenarios, organise recurring work and create decision-ready outputs.
Compare current, conservative and growth cases before committing to a change.
Test the same assumptions across multiple scenarios and see how the result moves.
Turn the calculation into a clear next-step recommendation.
MPPM connects the result and supporting metrics into one practical decision summary.
Start from the outcome you want, not only the result you have.
Work backwards from a target to the performance, volume or budget required.
Move from calculator result to something you can actually share.
Create structured outputs for managers, clients and recurring reviews.
Reuse important assumptions across connected decisions.
Connect this result with the other calculators in the MPPM workflow.
See how the decision changes over time.
Keep previous calculations, revisit assumptions and compare performance without deleting old work.
Compare the acquisition price with the value and margin of the conversions you acquired.
Use the same measurement period, channel and attribution method.
Divide ad spend by completed conversions.
Set a CPA target using gross profit, retention and sales value rather than an arbitrary industry number.
CPA is the average advertising spend per conversion. A low CPA is not automatically good if the resulting conversions have low value or poor quality.
Use connected calculators when the next question depends on another part of the economics.
Not always. CPA measures cost per conversion, while CAC can include broader marketing and sales costs per new customer.
Yes, if conversions occur with zero recorded advertising spend. Confirm attribution and cost coverage.
Revenue per conversion helps contextualise CPA against attributed revenue, but does not establish profit.
CPA is undefined with zero conversions. Enter more than zero conversions.
