How to use this calculator
- Enter values from one consistent period.
- Include all relevant costs, fees, or funnel stages.
- Select Calculate to refresh the estimate.
- Review the supporting metrics before making a decision.
Estimate how many paying subscribers your fan club needs to recover fixed costs after variable service costs and payment fees. The result separates first-month break-even from the recurring contribution each subscriber provides, helping you test pricing and cost assumptions before committing budget.
Contribution = Price × (1 − Fee rate) − Variable cost; Break-even subscribers = Fixed costs ÷ Contribution.
This is the minimum whole number of active paying subscribers required for subscriber contribution to cover the entered fixed costs.
It excludes taxes and future churn; model those separately when planning a multi-month launch.
With $5,000 in fixed costs, a $15 price, $2 variable cost, and 8% fees, contribution is $11.80 and break-even is 424 subscribers.
Use unique people who could reasonably see the fan club offer during the same measurement window.
Use settled revenue after refunds when evaluating realized performance; enter refund assumptions when forecasting.
Include every percentage or per-transaction fee in the relevant cost or fee input, without counting it twice.
Yes, if both campaigns use the same definitions, attribution window, currency, and treatment of costs.
No. The calculator is a planning estimate and does not automatically apply taxes or jurisdiction-specific rules.
