Newsletter Growth Calculator
Project your email newsletter subscriber growth over 6, 12, and 24 months based on your current list size and growth rate.
Projected Subscribers
Newsletter growth uses compound growth to project your subscriber count over time.
Future Subscribers = Current Subscribers × (1 + Monthly Growth Rate / 100)^Months
Example: 1,000 subscribers at 10% monthly growth = 3,138 in 12 months
Typical monthly growth rates:
- New newsletter (< 6 months): 10–30%
- Established newsletter: 3–8%
- Large newsletter (50k+): 1–5%
Growth strategies:
- Lead magnets and content upgrades
- Social media cross-promotion
- Referral programs (like SparkLoop)
- Paid subscriber acquisition ($1–5/subscriber typical)
Note: This assumes consistent growth. Actual growth often varies month to month, and churn (unsubscribes) should be factored in.
