This subscriber growth estimator models time to a target using your current subscriber count and observed net monthly gains. It assumes that the resulting percentage growth stays constant. It does not infer growth from channel age, predict YouTube recommendations or measure views-to-subscriber conversion. Use it as a scenario, not a promised milestone date.

Estimate time to a target if your observed monthly percentage growth stays constant. This compound-growth scenario is not a forecast or a views-to-subscriber conversion rate.
Formulas used
Months to target
ln(Target ÷ Current) ÷ ln(1 + Monthly gains ÷ Current)
Assumes constant positive monthly percentage growth; no timeline is available from zero growth.
The model assumes the same percentage growth every month, not a guaranteed target date. Zero or negative growth cannot project a higher target. A new channel needs observed growth first. Check your channel’s current public statistics.
Use your current subscriber total and net subscribers gained over one month.
Set a subscriber milestone. This is not a monetization-eligibility checker.
The result assumes your monthly percentage growth stays constant; actual growth can differ.
Creator planning a milestone
Challenge: Compare targets without promising a forecast
Solution: Model time to target, then revisit the inputs each month using observed net growth.
