What is K-Factor?
The K-Factor measures how quickly a product spreads through user referrals. It calculates how many new users each existing user generates. A K-Factor above 1 indicates viral growth, while below 1 means growth stabilizes or declines. SaaS and mobile apps use this metric to evaluate referral programs, viral loops, and user acquisition strategies. High K-Factor products typically leverage strong incentives and seamless sharing mechanisms.
