How the Subscription Growth Calculator Formula Works

The Subscription Growth Calculator utilizes a specific formula to project future subscribers. The formula is designed to account for both subscriber acquisition and churn, providing a realistic estimate of your growth potential. Here’s a breakdown of the formulas used:

  • For the initial estimate:
    current_subscribers * Math.pow(1 - (monthly_churn_rate / 100), time_horizon_years * 12) + (monthly_new_subscribers * 12 * time_horizon_years) * (1 + (growth_acceleration * time_horizon_years) * 0.5)
  • For the adjusted estimate:
    current_subscribers * Math.pow(1 - (monthly_churn_rate / 100) * 0.8, time_horizon_years * 12) + (monthly_new_subscribers * 12 * time_horizon_years) * (1 + (growth_acceleration * time_horizon_years) * 1.2)

This formula takes into account the compound effect of churn and growth, providing a range of potential outcomes based on varying scenarios. By adjusting the input values, you can see how different factors influence your subscriber growth.
