Why this calculator?

Subscription businesses can be hard to calculate or forecast accurately as they have many moving parts.

This calculator helps you work through the details quickly and produces a cost benefit analysis which contains key metrics and financial projections within minutes. This helps you compose a solid business case.

I designed this calculator to make a ROI calculation for justifying investment decisions in marketing, product development and financing of products, content or licenses.

You can download the spreadsheet which you can use as a template for these calculations as well once you've filled in the calculator.

Subscription business models have many moving parts. It makes it a bit challenging to produce a solid cost benefit analysis to determine if a business case will be profitable or not.
