How do I calculate YouTube subscriber growth rate?

Subtract the starting subscriber count from the current count, divide by the starting count, then multiply by 100.

Does this calculator connect to YouTube?

No. Enter two subscriber counts and the time between them manually. The tool does not access your YouTube account.

Is the goal timing a prediction?

No. If you enter a target, the tool extends the same net daily pace as simple arithmetic. Actual subscriber growth can speed up, slow down or reverse.

Where should I get my subscriber counts?

Use YouTube Studio or another record of the same channel at two different dates. YouTube Studio remains the source of truth.
