Viral Coefficient Calculator
Discover why cycle time is your most powerful growth lever. This interactive tool shows how small changes in timing create exponential differences in user growth.
Number of users you start with
Average number of invites each user sends
Percentage of invites that convert to users
Time from invite sent to new user activated
📈 Sub-viral, but still growing
Formula: (Invites per User × Conversion Rate) = 3 × 30% = 0.90
Key Insights
Cycle time compression has a multiplicative effect over time periods
Reducing cycle time from 7 days to 1 day gives you 7x more growth cycles in the same period
A 10% improvement in conversion rate is linear, but a 10% faster cycle time compounds exponentially
Focus on reducing friction in your referral flow before optimizing other metrics
