Work out subscriber growth projection instantly with clear inputs, formula shown and shareable results.
Net growth is gross growth minus churn, compounded monthly, and the doubling time follows from the logarithm of two over the logarithm of one plus the net rate. Churn compounds against you, so cutting churn from 4% to 2% does more for a channel than adding two points of gross growth.
Projection
subscribers = current x (1 + growth - churn) ^ months
Doubling time
months = ln(2) / ln(1 + net rate)
subscribers = current x (1 + growth - churn) ^ months. Net growth is gross growth minus churn, compounded monthly, and the doubling time follows from the logarithm of two over the logarithm of one plus the net rate.
