How it works
Methodology & formulas
This calculator is transparent by design. Review the steps and formulas so you can trust the estimate and adjust assumptions when your dashboard differs.
Calculation steps
- 1Calculate annual price from monthly and discount
- 2Monthly gross = paidMonthly × monthlyPrice
- 3Annual gross total yearly = annualSubs × annualPrice, monthly equivalent = total ÷12
- 4Total gross monthly = monthly gross + annual equivalent
- 5Substack fee = totalGross × substack%
- 6Stripe percent portion = totalGross × stripe%
- 7Stripe fixed portion = effective transactions × fixed
- 8Total Stripe = percent + fixed
- 9Total fees = substack + stripe
- 10Net monthly = gross - fees
- 11Effective rate = totalFees ÷ gross ×100
- 12Per subscriber = totalFees ÷ totalPaid
- 13Annual fees = monthly gross×12 fee + annual gross fee calculated yearly for accurate fixed count
Formulas
- AnnualPrice = monthly×12×(1-discount%)
- MonthlyGross = monthlySubs × monthlyPrice
- AnnualMonthlyEquiv = annualSubs×annualPrice ÷12
- TotalGrossMonthly = monthlyGross + annualEquiv
- SubstackFee = totalGross ×10%
- Stripe% = totalGross ×2.9%
- StripeFixed = (monthlySubs + annualSubs/12)×$0.30
- TotalFees = substack + stripe% + fixed
- Effective% = totalFees ÷ gross ×100
Important assumptions
- Annual price = monthlyPrice ×12 × (1 - annualDiscount%)
- Annual monthly equivalent = annualSubs × annualPrice ÷12
- Total gross monthly = monthlyGross + annualEquivalent
- Substack fee = totalGrossMonthly × substackFeePercent
- Stripe percent = totalGrossMonthly × stripePercent
- Stripe fixed = (monthlySubs + annualSubs/12) × stripeFixed
- Effective fee rate = totalFeesMonthly ÷ totalGrossMonthly ×100
- Fee per subscriber = totalFeesMonthly ÷ totalPaidSubscribers
