Mathematical Audit

How YouTube Growth Is Projected

Growth projection uses compound subscriber growth based on your current rate. Real YouTube growth is non-linear — channels accelerate once they hit algorithmic thresholds.

Linear Projection: Days to Milestone = (Milestone − Current Subs) ÷ Daily Growth Rate
Compound Projection: Future Subs = Current × (1 + Monthly Growth Rate)^Months
Daily Growth Rate = New Subscribers Last 30 Days ÷ 30
Monthly Growth % = (New Subscribers ÷ Start of Month Subs) × 100

Actual YouTube growth is not perfectly linear. Viral videos, algorithm picks, and seasonal trends cause spikes. Use compound projection for a more realistic estimate.
