Subscriber Growth Rate Calculator

Net subscriber growth compares subscriber additions and losses with the starting audience, giving a clearer picture than additions alone.

How to use this calculator

  1. Enter starting subscribers, new subscribers, unsubscribed subscribers using the same measurement window and units.
  2. Check the result and intermediate values, then change one input at a time when comparing scenarios.
  3. Keep the stated scope and assumptions attached to any result you share.

Formula and method

Ending subscribers = starting subscribers + gained − lost; net growth (%) = (gained − lost) ÷ starting subscribers × 100.

  • Ending count is 12,740; net growth is about 6.17%.
  • This is a count-based metric. It does not measure active audience quality, engagement, paid status or acquisition cost.
