Formula
Contribution per subscriber = price × (1 − fee rate) − variable cost
Break-even subscribers = fixed costs ÷ contribution per subscriber
The subscriber result rounds up because a fraction of a subscriber cannot cover the remaining cost.
What the result means
Use the main result as a planning estimate tied to the assumptions entered. Compare scenarios with the same definitions and period rather than treating the output as a guaranteed outcome.
This calculator is an operational estimate. It does not include taxes or costs you do not enter.
