FAQ
Questions Viral Coefficient Calculator owners ask.
- 01
What is the K-factor?
The K-factor (Viral Coefficient) represents the average number of new users generated by a single existing user. It is calculated by multiplying the average number of invitations sent per user by the conversion rate of those invitees.
- 02
How do I know if my product is viral?
A K-factor greater than 1 indicates exponential growth (Viral). A K-factor of exactly 1 represents steady, linear growth (Critical), and a K-factor below 1 means the viral loop will eventually stop without external input (Sub-critical).
- 03
Can I project future user growth?
Yes, by using the forecast_growth_trajectory capability, you can simulate and view the projected total user population for a specific number of future growth cycles.
