How to use this calculator
- Enter your current subscriber count.
- Add average monthly new subscribers.
- Add monthly lost subscribers to measure churn.
- Enter your subscriber goal and calculate.
Estimate YouTube subscriber growth from new subscribers and lost subscribers. Forecast goal timing, milestone progress, churn risk, and whether your channel is growing at a healthy pace.
A higher net subscriber growth rate with low churn shows a healthy channel. If subscriber losses are high, the health score drops even when new subscribers look strong.
Use recent 30 to 90 day averages. A single viral video can temporarily overstate your long-term subscriber velocity.
With 25,000 subscribers, 1,800 new subscribers, and 250 lost subscribers, net growth is 1,550 per month. A 50,000 subscriber goal is about 16.1 months away.
Use your current subscribers, monthly net gain, and target. The calculator estimates the months needed to reach 100,000 subscribers.
A strong channel often grows above 5% per month at smaller sizes, while larger channels may grow slower but more consistently.
Subscriber loss can come from content mismatch, inactive accounts, inconsistent uploads, or viewers unsubscribing after a viral mismatch.
Enter your current subscribers and monthly net growth. The calculator estimates how many months are needed for 10K.
Improve retention, create searchable evergreen videos, use clear subscribe CTAs, and build repeatable content series.
