Subscription Economics Sandbox
When sales open, you receive the digital product after purchase. The full product page below explains what the tool does, which workflow you follow and what you create at the end.
Subscription Economics Sandbox is a local-first JSP Original for Pricing, Money & Return. It is designed to make financial assumptions visible before you build business decisions on top of them.
What this tool calculates or builds
Based on your own input, the tool produces a twelve-month simulation of customer count and operating result based on price, costs, churn, and inflow.
What you enter
- Monthly price
- Variable cost per customer per month
- Monthly churn percentage
- New customers per month
- Fixed monthly costs
- Starting number of customers
Why this can be useful
A price or revenue number says little while costs, payment fees, volume, churn, or buffers remain invisible. This tool puts those assumptions next to each other so you can examine a scenario before treating a price, discount, subscription, or expense as obvious.
What do you receive?
- a self-contained browser calculator or builder;
- a directly calculated or assembled result based on your input;
- copy, print/PDF, and text-export functions;
- a README and personal/internal-use licence;
- no external account or API key required for the core function.
Privacy
The core calculation and working input remain in your browser and are not sent to JIM STEPHEN PINAS.
