A channel at 1,000 subscribers growing 10% a month gains 100 subs. Holding 10% at 100,000 means gaining 10,000 a month, which almost nobody sustains. Deceleration dampens your entered rate as the channel scales, interpolating between these points so the curve bends smoothly instead of stepping.
| Channel size | Rate applied |
|---|
| Under 10K | 100% |
| 100K | 85% |
| 500K | 70% |
| 1M | 60% |
| 2M and up | 50% |
| Uploads per week | Multiplier |
|---|
| None | 0.50x |
| 1 | 0.80x |
| 2 (baseline) | 1.00x |
| 3 | 1.10x |
| 4 to 5 | 1.15x |
| 6 or more | 1.20x |
In rate mode each month is: previous month × (1 + your rate × deceleration × upload multiplier). In flat mode a fixed number of subscribers is added each month, adjusted by the upload multiplier only. Read the full methodology.
