- Include store commissions and payment failures in variable cost.
- Compare monthly and annual-plan cohorts separately.
Calculator guide
Understanding Mobile App Subscription Economics Calculator
App-subscription economics connect paid installs, trial conversion, churn, store fees, service cost, acquisition spend, and fixed product expense.
Calculation method
How the calculation works
Model mobile app subscription membership movement from opening members, new acquisition and churn, then calculate recurring revenue, contribution, acquisition spend, operating profit, break-even membership, and a transparent gross LTV-to-CAC reference. Roll opening paid users forward by new members less churn, then subtract variable service, acquisition, and fixed monthly cost from ending revenue.
App subscriber loop
Move installs through paid entitlement and renewal
The visual separates opening members, new joins, churn, ending paid users, store cost, and operating profit.
Worked situations
Practical examples
- Install growth can coexist with declining paid members.
- A lower churn rate can improve LTV more than a small price increase.
- Annual plans improve cash timing but create renewal concentration.
Better inputs
Useful tips
- Track cohorts by platform and acquisition source.
- Separate trials, paid users, and grace-period accounts.
- Model store-fee tiers and refunds explicitly when material.
Before relying on the result
Limitations and common mistakes
- Constant churn, price, acquisition, and cost are assumed.
- Trials, upgrades, refunds, taxes, store tiers, and cohort aging are simplified.
- Gross LTV is not a valuation.
Reference
Key terms
- Paid subscriber
- User with an active successfully billed entitlement.
- Store commission
- Platform share of subscription receipts.
- Gross LTV
- Steady-state contribution divided by churn.
Important note
Calculated from the entered technical values using the displayed model. Validate topology, workloads, capacity, security, redundancy, and observed performance before implementation.
Frequently asked questions
Should trial users be included?
Only after conversion to a paid entitlement.
Where do store fees go?
Include them in variable cost per member.
Is LTV exact?
No, it is a constant-churn gross reference.
