FAQ
Questions Payback Period Calculator owners ask.
- 01
What is the payback period?
The payback period is the number of months it takes for a customer to generate enough gross profit to cover their initial acquisition cost (CAC).
- 02
How can I compare multiple marketing channels?
You can use the analyze_acquisition_channels capability by providing a JSON array of your channel data, including CAC, ARPU, and gross margin for each.
- 03
How does the budget recommendation work?
The recommend_budget_allocation capability uses an inverse payback weight logic. It prioritizes channels with shorter payback periods, allocating a larger portion of your total budget to the most efficient channels.
